EMPLOYER AND EMPLOYEE
RESPONSIBILITIES
The installation and maintenance of evaporative
coolers at height has the potential to create
Occupational Health and Safety issues for
those involved. Installers are advised to ensure
they are familiar with the relevant State and
Federal legislation, such as Acts, Regulations,
approved Codes of Practice and Australian
Standards, which oer practical guidance on
these health and safety issues. Compliance
with these regulations will require appropriate
work practices, equipment, training and
qualications of workers.
Seeley International provides the following
information as a guide to contractors and
employees to assist in minimising risk whilst
working at height.
CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-J | 5
As with any product that has moving parts
or is subject to wear and tear, it is VERY
IMPORTANT that you maintain your cooler

MAINTENANCE NOTE
IMPORTANT SAFETY INSTRUCTIONS
INSTALLER AND MAINTENANCE
CONTRACTORS - RISK ASSESSMENT
Installer and Maintenance Contractors
A risk assessment of all hazardous tasks is
required under legislation. A risk assessment is
an essential element that should be conducted
before the commencement of work, to identify
and eliminate the risk of falls or to minimise
these risks by implementing control measures.
There is no need for this to be a complicated
process, it just is a matter of looking at the job
to be done and considering what action(s) are
necessary so the person doing the job does not
injure themselves.
This should be considered in terms of:
• What are the chances of an incident
happening?
• What could the possible consequence be?
• What can you do to reduce, or better still,
completely get rid of the risk?
SOME POINTS TO CONSIDER
• What is the best and safest access to the
roof and working areas?
• If a worker is alone, who knows they are
there and if they get into diculty, how can
they summon help?
• (Call someone on the ground? Mobile
phone? etc.)
• What condition is the roof in? Should the
trusses, underside or surface be checked?
• Does the worker have appropriate foot
wear? (Flat sole jogger type is advisable)
• Are all power cables / extension leads safe
and appropriately rated?
• Are all ladders, tools and equipment suitable
in good condition?
• Where ladders are to be used, is there a
rm, stable base for them to stand on?
Can they be tied or secured in some way
at the top? Is the top of the ladder clear of
electricity supply cables?
• Is there a roof anchor to attach a harness
and lanyard to? If so, instruction should be
issued for the use of an approved harness
or only suitably trained people used.
• Are all tools and materials being used,
prevented from slipping and falling onto a
person at ground level? Is the area below
the work area suitably protected to prevent
persons walking in this area?
• Does the work schedule take into account
weather conditions, allowing for work to be
suspended in high winds, thunder storms/
lightning or other types of weather giving
wet, slippery surfaces?
• Is there an on-going safety check system of
harnesses, ropes, ladders and access/lifting
equipment and where they exist on roofs,
anchor points before the commencement of
work?
• Is there a system which prevents employees
from working on roofs if they are unwell or
under the inuence of drugs or alcohol?
• Are there any special conditions to consider
i.e. excessive roof pitch, limited ground
area, fragile roof, electrical power lines?
OTHER IMPORTANT REQUIREMENTS
• Never force parts to t because all parts are
designed to t together easily without undue
force.
• Never drill holes in the tank of the cooler.
• Check the proposed cooler location, to
ensure that it is structurally capable of
supporting the weight of the cooler, or
provide an adequate alternate load bearing
structure.
• Ensure the installation complies with all
local and national regulations with regards
to electrical, plumbing and bushre
construction requirements.

TECHNICAL DESCRIPTION
AIRFLOW
The cooler has a single fan which draws hot outside air through
the rear-mounted air lters, through the dry channels of the air-
to-air indirect evaporative heat exchangers and into the plenum
at the front of the cooler.
Inside the plenum, the air is split into an exhaust ow and a
supply ow.
The exhaust air passes through the wet channels of the air-to-
air indirect evaporative heat exchangers and out through the
upper exhaust grille back to atmosphere.
The supply air passes over a secondary direct evaporative
cooling stage (Supercool cooler only), before entering the
customer's ductwork.
HEAT EXCHANGERS
Indirect Evaporative Cooling (IEC) Stage
All coolers have air-to-air indirect evaporative heat exchangers,
composed of alternating dry and wet channels separated by a
membrane. CW-H10 has 2 and CW-H15 has 3.
Through evaporation and conduction, heat is transferred from
the air in the dry channels, across the membrane, and into the
air in the wet channels.
The air in the dry channels is progressively cooled, but gains no
additional moisture.
Direct Evaporative Cooling (DEC) Stage
Supercool coolers are tted with a secondary direct evaporative
cooling stage.
The cooled air from the IEC stage passes over saturated
Chillcel® media, where, through evaporation, it is cooled further
with an increase in moisture content.

TRANSPORT
UNPACKING THE COOLER
The cooler will be delivered on a dedicated pallet and will be
wrapped in plastic lm which will need to be removed before
installation.
A small bag of installation components along with the exhaust
transition side rails and grilles can be found under the lid of the
main cabinet of the cooler. The exhaust transition will need to
be raised into place before operation.
WARNING: Once unwrapped, the exhaust transition assembly
should be tted together as soon as practicable to avoid loose
components becoming lost/damaged and/or a hazard.
MOVING THE COOLER
The cooler can be moved by forklift truck. Only use the
openings on the cooler. Do not lift through the pallet.
ILL1916-A
Min. forklift tyne gap

LIFTING THE COOLER
The cooler may be lifted by crane with slings through the cooler
base forklift truck tyne openings.
Do not attempt to lift using any cabinet features or by retrotting
lifting lugs. The cabinet may be damaged and/or lift safety
compromised.
It is recommended to use a spreader bar on the straps or slings
to protect the upper edges of the cooler with a corner protector
beneath the lifting straps to avoid any damage to the cabinet
during the lift.
12 | CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-J
The cooler base has a series of mounting holes for securing
the cooler. Dimensions and locations of the mounting holes are
shown in the cooler views at the beginning of this manual.
Where necessary, installers should use a sucient number of
suitably rated vibration isolation mounts to support the operating
mass of the cooler.
DRIP-TRAY
When coolers are installed indoors, or anywhere that water
leakage could cause damage, install a corrosion resistant drip
tray under the whole unit.
Recommended sizes:
CW-H10:
1500 x 1300 x 50mm (59” x 51” x 2”)
CW-H15, H15S, H15S PLUS:
1500 x 1900 x 50mm (59” x 75” x 2”)
Apply silicone sealant between drip-tray and cooler base at
every xing.
SUPPLY AIR DUCT CONNECTIONS
Dimensions for the supply air duct interface are shown in the
cooler views at the beginning of this manual.
Vibration absorbing exible connections are recommended for
all duct connections to the cooler.
All ducts must be independently supported.
All duct direction changes must utilise a generous radial turn
with internal air directors to minimise turbulence and maximise
eciency.
All ducts are to be suitably insulated to minimise temperature
losses.

COOLER LOCATION
Check the proposed cooler location, to ensure that it is
structurally capable of supporting the weight of the cooler, or
provide an adequate alternate load bearing structure.
Model Shipping Weight Operating Weight
CW-H10 250KG (550 LB) 255KG (560 LB)
CW-H15 340KG (750 LB) 330KG (728 LB)
CW-H15S, H15S Plus 355KG (783 LB) 345KG (761 LB)
Always locate the cooler where it will receive a plentiful supply
of fresh air, NOT in a recess where it may be starved for air or
where the air is polluted. Provision must be made for access to
electricity, water supplies and drains.
Air exiting the cooler exhaust is warm and heavily laden
with moisture. Ensure the cooler’s exhaust air will not cause
corrosion or damage to other nearby items. Do not allow
exhaust air to re-circulate into the air intake of the cooler.
Ensure the cooler location is a minimum of:
• 3.0m (10’) from a solid fuel heater ue
• 1.5m (5’) from a gas ue
• 1.0m (3.5’) away from adjacent solar panels or similar roof
mounted xtures
• 6.0m (20’) from a sewer vent
• 3.0m (10’) (preferably 5.0m (17’)) away from any TV antenna
or antenna cables. Make sure the cooler is not between the
antenna and the transmission tower that is providing the
television signal to the home.
ILL1925-A
Extra service or warranty charges may apply for the cost of any
equipment or additional labour involved in accessing the cooler
if these guidelines are not met.
Note! Do you need to discuss the installation of items like
safety anchor points with the customer?
ACCESS FOR SERVICING AND
MAINTENANCE
The cooler should be installed in a position that allows adequate
access for installation, and future maintenance and servicing
activities. This should comply with installation guidelines and
any local, State and National regulations.
Consider the following for installation location:-
• Which has clear access to and around the cooler
• Which is clear of xtures in line with below clearances
• Which is clear of fall edges (> 3m (10') away)
• Which is structurally capable of supporting the weight of the
cooler and service technicians
Required clearances around the cooler for future maintenance

ELECTRICAL REQUIREMENTS
ELECTRICAL SUPPLY INSTALLATION
INSTALLATION OF THE COOLER MUST CONFORM
TO LOCAL ELECTRICAL RULES, REGULATIONS AND
STANDARDS.
It is a requirement of Seeley International that all coolers be
wired with a dedicated circuit and circuit breaker/fuse at the
distribution board.
A mains isolation switch, with all pole disconnection, shall be
furnished by the contractor and installed adjacent to the cooler.
IMPORTANT! There are specic models for regional voltages
and frequencies which are not interchangeable. Specically, the
fan motor(s), transformer(s) and pump(s) may be unique to the
voltage/frequency of supply.
See the cooler rating label for the correct electrical data. Before
connecting the device, make sure the power supply matches
the cooler voltage and frequency.
Electrical Supply Specication (50Hz Option):
380-415V / 50 Hz / 3N~ / 4.9A (FLA)
Electrical Supply Specication (60Hz Options):
440-480V / 60 Hz / 3~ / 9A (FLA) 11.5A (MCA) 15A (MOPD)
200-240V / 60 Hz / 3~ / 11A (FLA) 14.5A (MCA) 20A (MOPD)
200-240V / 60 Hz / 1~ / 8A (FLA) 10.5A (MCA) 15A (MOPD)
Mains power terminals are provided inside the electrical cabinet
with glands provided for cable entry.
MOTOR LOCKED-ROTOR PROTECTION
Due to the built-in motor locked-rotor protection, the starting
current (LRA) is equal to or less than the nominal current (FLA).
FIRE TERMINALS
A pair of terminals labelled "FIRE" are provided for integration
with a building re management system.
These terminals provide power to the cooler controls and are
supplied with a bridge.
To use with a building management system, remove the bridge
and connect the terminals through a NORMALLY CLOSED
relay which opens in a re event.
Interrupting power to the PLC will immediately stop all cooler
components, including fans.
HIGH LEAKAGE CURRENT
IMPORTANT! High leakage current. Earth connection
essential before connecting supply.
The cooler utilises a fan motor with a built in inverter drive. To
comply with EMC regulations these drives adopt EMC lters
that connect to the motor earth terminals. The normal lter
leakage current to earth may accumulate to a total leakage
current in excess of 10mA. For asymmetrical power systems or
if a phase fails, the leakage current can increase to a multiple of
the nominal value.
To comply with regulations and to prevent electric shock this
leakage current must be properly addressed.
In particular, the earth terminal at the mains power point of
connection must be properly connected and earthed. Power
must not be applied until this is correctly completed.
RESIDUAL CURRENT CIRCUIT BREAKER
(RCCB)
The cooler utilises a fan motor with a built-in variable speed
drive (VSD). If local electrical standards require the use of a
residual current circuit breaker (RCCB), only AC/DC-sensitive
residual current devices (type B) are permissible. If incorrectly
selected and/or sized, pulsed charging currents from the
capacitors in the integrated EMC lter can lead to the instant
tripping of RCCB when the cooler power supply is switched on.

24VDC POWER SUPPLY
The cooler is provided with a 24VDC switch mode power
supply for use with internal components and optional sensor
accessories. The maximum power available for external
components is 30W.
TRANSFORMER TAPPINGS
440-480V / 3~ coolers ONLY are tted with a transformer to
power the cooler electronics. By default the input voltage
jumper is set for 480V. If the power supply has a dierent
phase-to-phase voltage, reposition the jumper as per the table

WATER SUPPLY INSTALLATION
The cooler requires a permanent water supply to be
connected. A built-in Inlet Solenoid Valve, controlled by the
water management system, allows water into the cooler when
required.
INSTALLATION OF THE WATER SUPPLY MUST CONFORM
TO LOCAL PLUMBING RULES, REGULATIONS AND
STANDARDS.
The following specications for water supply are required:
Water Connections:
½” BSP (Aus/Eur), ½” NPT (USA) male.
Water Supply:
100kPa (15psi) - 800 kPa (115psi)
10L/min (2.6 gal/min) MINIMUM
20L/min (5.3 gal/min) RECOMMENDED
Water Supply Temperature:
40°C (105°F) MAXIMUM
Water Supply Salinity:
100 to 1150μS/cm
ILL1940-B
WATER REQUIREMENTS
WATER SUPPLY PRESSURE REGULATION
The Installer must provide a pressure regulator in the water
supply line adjacent to the cooler to regulate water supply
pressures between 100kPa (15 PSI) and 800kPa (115 PSI).
Important! Water pressures which are lower than 100kPa (15
PSI) will prevent the inlet solenoid valve from opening.
Important! Water pressures which are higher than 1200 kPa
(175 PSI) and/or water temperatures which are higher than
40ºC (105ºF) risk inlet solenoid valve failure.
Water pipes installed on the outside of a building, or any other
exposed location, shall have adequate insulation to protect
against freezing in the winter and solar radiation heating in the
summer.
If a non-return valve is installed in the water supply line, it
is recommended that a suitable pressure relief valve is also
installed between the cooler and the non-return valve to limit
the pressure rise associated with the heating eects of ambient
temperature and solar radiation.
WATER SUPPLY ISOLATION
The Installer must provide a manual 1/4 turn ball type shut o
valve (do not use a stop cock) in the water supply line adjacent
to the cooler, subject to local plumbing regulations. This allows
the water supply to be isolated whenever work needs to be
done on the cooler.
In areas where temperatures can cause water supply pipes
to freeze, a drain down facility should be provided during the
installation. This drain down facility must be activated prior
to freezing conditions to avoid possible damage to the cooler
components.
WATER SUPPLY FILTRATION
The Installer must provide an inlet water lter in the water
supply line, external to the cooler, to prevent any debris from
entering and damaging cooler components.
Important! Flush the water pipe to remove any contaminants
(swarf, lings or dirt) before nal tting. Contaminants can
lodge in the inlet solenoid valve, preventing it from functioning
correctly.
The cooler's water management system is designed to use
water that is suitable to be classied as ‘potable’ and t for
human consumption. If alternative water (including rain water) is
to be used that contains unusually high or low levels of salinity,
hardness, acidity or chemical contaminants, then additional
ltration or treatment systems should be employed to render the
water ‘potable’.
WATER HAMMER
Not all installation pipeworks are the same, and some may
require additional prevention against water hammer. If water
hammer is a problem, it is the responsibility of the Installer to t
an appropriate water hammer arresting device external to the
cooler.

CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-J | 17
WATER DRAIN INSTALLATION
The cooler requires a permanent water drain to be connected.
A built-in drain valve, controlled by the water management
system, releases water from the cooler when required.
INSTALLATION OF THE WATER DRAIN MUST CONFORM
TO LOCAL PLUMBING STANDARDS.
Drain Connections:
The cooler installation kit contains components to congure the
drain valve discharge to one of the following options:
- Down or Rear Discharge
- 1.5" (40mm) BSP Male or 1.5" Flexible Coupling.
Drain Rate:
15 L/min (4 gal/min)
Important! Water drained from the drain valve is high in salinity
and must be carried away to a suitable discharge point on the
building or property. Never drain the water directly onto the roof
ILL2442-E
ILL2442-E
ILL2443
The removable access panel should be re-assembled after
drain line installation.
Important! Drainage systems with long pipe runs, multiple entry
points, and/or incorporating traps shall use a tundish or similar
device to create a 25mm (1") air-gap between the bottom of the
drain valve and the drainage system.

FAN SPEED MANAGEMENT SYSTEM
The cooler fan is driven by an electronically commutated DC
motor with integrated variable speed drives (VSD) that allows
for 0-10Vdc speed control.
The fan speed is controlled by the inputs from the Primary
Control Method (e.g. Multi-Magic Wall Controller). Depending
upon the control type, speed control is either continuously
variable or in 10 discrete speed steps (Speed 1-10).
If, when commanded to start, the fan start delay option is
enabled, the fan will remain o until the delay timer has expired.
Upon starting, the fan will initially run at a xed slow speed for
30 seconds before increasing to the requested speed.
If pre-wet is enabled, the supply fans will remain at the xed
slow speed until the pre-wet cycle is complete.
WATER MANAGEMENT SYSTEM
The cooler contains multiple parts to supply, distribute and
manage the water needed for the heat exchangers.
Water Inlet Solenoid Valve
The inlet solenoid valve allows water into the water reservoir. It
is open during the following phases.
• Initial Tank Fill
Trigger: Entering IEC or DEC mode.
• IEC Tank Fill
Trigger: Indirect Watering Cycle = TANK FILL.
• DEC Only Tank Fill
Trigger: Low Probe = WET.
Once open, the inlet solenoid valve will remain open until the
water high probe has detected water for at least 5 seconds.
If the water drain valve is open, the inlet solenoid valve will
remain closed.
Indirect Pump Control (IEC Watering Cycle)
The indirect pumps move water from the reservoir to the 3
indirect heat exchangers.
The indirect heat exchangers do not require continuous
watering and the pump runs on the following cycle
• Tank Level OK - Water lled to high probe and waiting for
next IEC pump cycle to start.
• Indirect Pump Running (60 seconds).
• Core Drain - IEC pump stopped and excess water is
draining back to the reservoir (1 minute 30 seconds)
• Tank Fill - IEC pump stopped and inlet solenoid valve open
and re-lling to high probe (6 minutes 30 seconds)
Total IEC pump on time = 1 minute
Total IEC pump o time = 8 minutes
Direct Pump Control (Supercool coolers only)
The direct pump moves water from the reservoir to the Chillcel®
media. When running in DEC mode the direct pump runs
continuously. Excess water from the Chillcel® media drains
back to the reservoir.
COOLER CONTROL COMPONENTS
Water Salinity Control
As water evaporates from the heat exchangers, the salinity of
the remaining water naturally increases.
The water management system uses the 3-pin water probe to
measure water conductivity as a proxy for salinity. The probe
can sense conductivity down to 9 µS (about 4ppm) .
Water conductivity is updated every time water reaches the high
probe and, when it exceeds the upper set point, a salinity drain
cycle will start.
Chlorinator Control
The chlorinator is composed of specially treated plates. When
energised and submerged in water, electrical current ows
between the plates generating chlorine which is known to kill
bacteria in water supplies.
The chlorinator is active when the cooler is in IEC mode, AND
the water level is above the bottom probe AND the water
conductivity is >1500 µs/cm.
If the water conductivity remains <1500µs/cm for 24 hours, a
clean tank drain cycle will start.
Water Tank (Reservoir) Drain Valve
The drain valve will automatically open when power is rst
applied to the cooler. It will close again when IEC or DEC mode
is enabled.
During a salinity drain cycle, the drain valve opens until the
water level falls below the low probe, then the drain valve
closes immediately, and inlet solenoid valve opens to rell the
reservoir with fresh water.
During a clean water drain cycle, the drain valve remains open
for 10 minutes, after which the inlet solenoid valve opens to rell
the reservoir with fresh water.
The drain valve will open if it has been 3 days since IEC or DEC
mode was last run.

PRE-WET
Upon cooler start-up, Pre-Wet rst ensures the water tank is full
and then runs an extra 6-minute start up pump cycle to saturate
the heat exchanger cores.
During this Pre-Wet phase, the supply fan will be restricted to
Speed 1 regardless of controller input.
Pre-Wet ensures only cooled air is delivered, at the expense of
a longer start up time.
The Pre-Wet sequence will run again if the pumps have not run
in the last 30 minutes.
FAN START DELAY & RUN OUTPUT
RELAY
The Fan Start Delay can be a positive or negative timer.
If a positive timer is selected, the fan run output relay changes
state but the fan does not start until the timer has expired.
For example, this can be used to open or close 3rd party
dampers before the cooler fans start.
If a negative timer is selected, the fans start when requested,
but the fan run output relay does not change state until the timer
has expired.
For example, this can be used to ensure internal building
pressure is maintained before opening 3rd party relief vents.

AIR FLOW BALANCING
In order for the cooler to produce cool air it is mandatory that
some of the inlet air is forced to return through the indirect heat
exchanger cores and be exhausted to atmosphere. Therefore
only a proportion of the total inlet air is delivered into the cooled
zone.
THIS PROPORTION IS CRITICAL TO ACHIEVING
SATISFACTORY PERFORMANCE.
The supply air transition is equipped with a damper that can
be adjusted to 'balance' the proportion of supply and exhaust
air streams. Damper position is controlled through a lever with
locking screw located underneath the supply air transition.
The damper will need to be adjusted during commissioning
depending on the external static pressure of the duct system.
ILL2447-A
ILL2447-A
To balance the air ow.
1. Ensure all side panels and air lters are in place.
2. Connect all external supply and exhaust ductwork.
a. Stand-alone Cooling: Fully open all supply air outlets
in the entire ductwork system.
b. Pre-Cooling: Ensure all main Air Conditioning plant
fans are running at full speed - consult with Building
Manager and/or Air Conditioning contractor.
3. Using the cooler's PLC, start the Climate Wizard in LOCAL
and IEC modes at Speed 10.
4. Wait approximately 5 minutes, to allow the cooler to
complete the rst water ll and the pumps to start.
5. Adjust the supply air transition damper until the pressure in
the transition stabilises as follows:
a. CW-H10: 200 Pa (0.80 in wg static)
b. CW-H15: 175 Pa (0.70 in wg static)
c. CW-H15S: 175 Pa (0.70 in wg static)
d. CW-H15S Plus: 210 Pa (0.84 in wg static)
6. For multiple CW-H coolers connected to the same supply
duct, it may be necessary to re-check and adjust the supply
air transition pressures of all coolers after each cooler is
set.
7. For stand-alone cooling, balance all customer’s supply air
outlets in your usual manner. After balancing, check and
adjust the CW-H damper back to the above values.
8. Lock the damper in its nal position and record the nal
value.
Supply Transition Pressure = ................................
ILL3884-A
There is a hole in the right hand side of the supply air transition
suitable for manometer tubes for measuring pressure.
NOTE! Pressure measuring should be carried out using
an accurate instrument, either electronic or “inclined tube
manometer”. DO NOT GUESS.

MAINTENANCE FREQUENCY
Maintenance of an indirect evaporative cooler is essential in maintaining proper performance and reliability.
All maintenance must be done by competent, qualied, licensed technicians, in accordance with National and/or Local Regulations.
The frequency of service is largely dependent on the conditions under which the cooler is operated. External factors, such as air and
water quality, can aect the serviceable life of the cooler and its components. In particular, installations using hard water, usually
dened as greater than 200mg/L, will experience greater scaling problems requiring a more frequent cleaning regime.
Similarly, the amount and type of use can also have a signicant impact. The guidelines listed below are intended to provide help in
formulating a proper service regime. Local, and in some cases, individual factors should be taken into account when deciding on the
frequency of visits.
HEALTH REGULATIONS. In some regions, regulations require that evaporative air coolers be serviced at specic intervals. Ensure
all maintenance is done in accordance with any local and national regulations.

MAINTENANCE SCHEDULE
WINTER OPERATION AND SHUTDOWN
Climate Wizard coolers cannot be used in any cooling mode (INDIRECT, DIRECT or SUPERCOOL) in freezing conditions. In
particular the inlet water solenoid valve, pumps, and drain valve are likely to fail in such conditions.
It is recommended that, to prevent damage to cooler components, the following tasks are completed before the start of the winter
season.
1. Drain and clean the reservoir.
2. Drain down and isolate the water supply.
3. Isolate the power.
For installations requiring continuous operation through the winter, it is possible to run the cooler in VENT mode down to -20
o
C
(-4
o
F), however customers must ensure the controls are not accidently set to any cooling mode in these conditions.
Coolers tted a Multi-Magic Ambient Sensor will automatically enable freeze protection. See page 27 for full details.

3. Seeley also warrants the Fan Motor for the rst three (3) years from the date of the Goods purchase, if upon examination prove
defective by reason of improper workmanship or material, We will repair or replace at our option, the Fan Motor or any part
thereof without charge for parts, during normal working hours.
4. During the period to which any expressed warranty applies, all defective part(s) shall be replaced or repaired (at the discretion
of Seeley) without charge for either parts or labour, during normal working hours. Should we deem in our absolute discretion
to replace the Goods pursuant to clause 1 or clause 3, we may substitute any similar good even if it is not on our current price/
equipment list. Further, Goods presented for repair may be replaced by refurbished goods of the same type rather than being
repaired. Refurbished parts may be used to repair the Goods.
5. We are under no obligation to repair or replace the Goods or Parts under clause 1 and 3 above if (i) the Goods have not been
installed and commissioned in accordance with the Installation Manual (ii) the Goods have not been installed and commissioned
properly or competently, (iii) the Goods have not been operated, serviced and maintained in accordance with the instructions
provided in the Owner’s Manual, or (iv) if any such service or maintenance has not been properly or competently performed. It
is a condition of warranty cover that each item in the Maintenance Schedule in the Owner’s / Operation / Service Manual (if it
was published with such a Schedule) is performed with the frequency indicated, by a qualied, licensed technician, and that the
Maintenance Schedule is properly lled out (ie names, signature, date, and action taken) when the item is completed. Any failure
to carry out the required maintenance and servicing requirements, and any failure to properly ll out a Maintenance Schedule
in the Manual, will void your warranty. The addition of any third party device, (except where it is required by the installation
instructions and complies with those instructions), or the removal or alteration of any Seeley component, or damage due to
misuse of the unit, or faulty installation or commissioning, will void this warranty.
6. As far as the law permits, We will not be liable for any consequential loss suered through, or resulting from, the non-operation,
or ineective operation of the cooler. The warranties granted under clause 1 and clause 3 do not cover damage to the cooler or
other loss resulting from acts of God.
7. No other person, company or corporation is authorised to oer, or give on our behalf, any other warranty. The benets conferred
are in favour of You and any person deriving title to the cooler whilst in its original place of installation. Nothing in this warranty
shall be construed as aecting any rights You may have under all the relevant laws, or Commonwealth or State Legislation which
give You rights which cannot be modied or excluded by agreement.
8. In order to claim under the warranties granted under clause 1 or clause 3 You must:
a) either:
• contact us within the Relevant Warranty Period on Australia 1300 650 644; or
• log a warranty claim on our website (website address below) within the Relevant Warranty Period; and
b) make available for inspection by the service agent who will come to the location of the Goods or send to us at the address

and daytime telephone number, the address at which the Goods are installed, and the model and serial number of the
Goods.

WARRANTY TERMS (AUSTRALIA)
9. The warranty granted in clause 1 and clause 3 covers the costs of parts and labour but you will be responsible for:
a) the cost of travel incurred for a Seeley International service agent to get to and from the location of the Goods if the
location of the Goods is either: (i) outside the metropolitan areas of the capital cities; or (ii) more than 35 kilometres from an
authorised Seeley International branch or service representative; and
b) any costs for additional labour or equipment associated with gaining acceptable and safe service access to the Goods

and
c) any costs incurred by the Seeley International service agent in gaining access to the Goods which is necessary to comply
with any safety or workplace safety requirements and/or any other relevant regulations. For the avoidance of doubt, the
reference to any costs incurred also includes the cost of any necessary site inductions.
10. We are not responsible in any way for any failure and/or inadequate performance of the Goods which arises from or is connected
to the use in the Goods of non-genuine spare parts. Seeley International strongly recommends that only spare parts supplied or
approved by it are used in the Goods.
11. The employees and Executive of Seeley International are not responsible for the installation of the Goods and expressly disclaim
all liability resulting from incorrect installations or installations that do not conform to local electrical codes, local plumbing codes,
Occupational Health and Safety requirements, and by laws which are legislated or in eect at the time of installation.
12. This warranty is only valid and enforceable in Australia.
Note: It is important that the safety and privacy of our service technicians is protected at all times. Accordingly, We and our Seeley
International service agents reserve the right to refuse service if (i) safety and accessibility to the unit cannot be guaranteed or
(ii) the owner of the unit, occupant of the site where the Goods are located, or any other third party seeks to take photographs, or
make a video or audio recording, of the service technician(s) while they are on the site or carrying out service to the unit. If a service
technician attends the site but subsequently leaves for any of these reasons then a service charge will be made for the call which
charge shall be a debt immediately due and payable by the person or entity that has made the claim under this Warranty. If a service
call reveals no warranty fault found with the Goods, a charge will be made for the call.
Our liability under this warranty is limited to the extent permitted by law. That is, to the extent that it is fair and reasonable, if the
Goods are not of a kind ordinarily acquired for personal, domestic or household use or consumption, your remedies associated with
any failure or defect of the Product will be limited to:
a) the replacement of the Goods or the supply of equivalent goods;
b) the repair of the Goods;
c) the payment of the cost of replacing the Goods or of acquiring equivalent goods; or
d) the payment of the cost of having the Goods repaired
and subject to the terms and conditions included in this warranty.

EXPRESS WARRANTY STATED HEREIN, AND YOU RELEASE AND DISCHARGE US FROM ALL OTHER CLAIMS,
WHETHER IN CONTRACT OR TORT, BY STATUTE OR COMMON LAW, AND YOU FURTHER AGREE TO INDEMNIFY
AND HOLD US HARMLESS FROM ALL OTHER CLAIMS (INCLUDING BUT NOT LIMITED TO CLAIMS ALLEGING
PRODUCT LIABILITY, STRICT LIABILITY, DECEPTIVE TRADE PRACTICES, BODILY INJURY, AND/OR PROPERTY
DAMAGE) TO THE MAXIMUM EXTENT PERMISSIBLE UNDER LAW).
THE EXPRESS WARRANTY PROVIDED HEREIN BY SIA IS THE SOLE AND EXCLUSIVE WARRANTY AND IS IN
LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE HEREBY
DISCLAIMED. EXCEPT FOR THE EXPRESS LIMITED WARRANTIES HEREIN, THE CLIMATE WIZARD COOLER IS
SOLD “AS IS, WHERE IS.” NO OTHER PERSON OR ENTITY IS AUTHORIZED TO OFFER, OR GIVE YOU, ON OUR

the purchaser). The date the Cooler was commissioned must be provided to Seeley at the time of warranty registration; or
(2) If the date the Cooler was originally commissioned cannot be veried by Seeley, the installation date shall be deemed to be the
date on the purchaser’s invoice for the purchase of the Cooler.
However, if the Cooler is not installed within 90 days of the date on the purchaser’s invoice for the purchase of the Cooler, then the
warranty coverage commences on the date that is 90 days from the date on the purchaser’s invoice.

SUBJECT TO THE CONDITIONS AND EXCEPTIONS STATED HEREIN, your remedies for any claim related to the CLIMATE

If SIA elects to replace or repair either parts or coolers, SIA may, in its discretion, use refurbished parts or coolers in making
the replacement or repairs, and may, in its discretion, substitute similar SIA authorized parts or coolers instead of the identical
warranted part or cooler, even if such parts or coolers are not on its current price/equipment list. You shall have no recourse for
breach of the Express Limited Warranty if written notice of claim is not received by SIA within the applicable Relevant Warranty
Period, in which case your claim shall be deemed time-barred for all purposes.

from you your business and/or property, but the assignee has no further right of assignment); and
10. normal wear and tear; and
11. the cooler’s cooling performance, eciency, water, and electricity consumption, all of which may vary widely depending upon

oat valves, plumbing components, cooler pads); and
15. calcication of the cooler pads, since calcication may be aected by minerals in the water supplied to the cooler and in the

components) which is the responsibility of your Supplier and/or installer; and
17. acts of God or nature, e.g., re, ood, tornado, power outage, lightning, dust storm; or acts of theft or vandalism; or any
intentional act which impairs the utility of or damages the cooler; and
18. all costs of labour and travel incurred in connection with repairing or replacing a defective part or the cooler; and

performed, and the name, signature and contact details of the qualied, licensed technician who performed the work; OR
24. any installation, commissioning, service or maintenance has not been properly or competently performed in accordance with
applicable electrical, plumbing, building and safety codes and regulations; OR
25. use of any replacement parts or spare parts not authorized by SIA; OR

premises).
EVEN IF THE EXCLUSIVE CONTRACTUAL REMEDY (OF REPAIR, REPLACEMENT, OR REFUND OF THE PURCHASE
PRICE) PROVIDED HEREIN FAILS OF ITS ESSENTIAL PURPOSE, SIA SHALL NOT BE LIABLE TO YOU FOR ANY
CONSEQUENTIAL, INCIDENTAL, INDIRECT, PUNITIVE, EXEMPLARY, OR SPECIAL DAMAGES, INCLUDING, WITHOUT
LIMITATION, LOST REVENUES, DOWNTIME, LOSS OF USE, SUBSTITUTE EQUIPMENT, GOODWILL, DAMAGE TO OR
