INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1.Installation work and electrical wiring must be done by
qualied person(s) in accordance with all applicable codes
and standards, including re-rated construction.
2. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
3. Ducted fans must always be vented to the outdoors.
4.Do not use this fan with any solid-state speed control device.
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 National 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.
INSTALLER AND MAINTENANCE CONTRACTORS -
RISK ASSESSMENT
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 (reservoir) 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/
wildre construction requirements.

INSTALLATION
PACK OUT KIT CONTENTS
COOLER LOCATION
Check the proposed cooler location to ensure it is structurally
capable of supporting the weight of the cooler. If the roof is
structurally inadequate, provide an alternate load bearing
structure.
The ideal location for the cooler is in a central position on the
roof (away from sleeping areas and where people spend most
of their time) so that the duct runs are of approximately the
same length. Carefully consider neighbouring residences and
noise levels when locating the cooler, if necessary talk to the
customer and the neighbour before carrying out the installation.
Always locate the cooler where it will receive adequate fresh air
and not in a recess where it may be starved for air or where the
air is polluted.
Ensure location is a minimum of:
• 10’ (3m) from a solid fuel heater ue,
• 5’ (1.5m) from a gas ue,
• 17’ (5m) from a sewer vent, and
• 2’ (600mm) from a wall.
The cooler must be mounted at least 10’ (3m), preferably 17’
(5m), 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.
Allow adequate access to and around the cooler for
maintenance. Provision must be made for access to electricity,
water supplies and drains.
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 (> 10’ or 3m away)
• Which is structurally capable of supporting the weight of the
cooler and service technicians
Required clearances around the cooler for future maintenance
and servicing are shown adjacent.

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.
New Installation
Use 24G or stronger metal roof jack. The cooler may then be
attached directly to the jack.
Replacement Installation
Roof Jack recommended wall thickness should be 24G or
stronger. The supplied roof jack adaptor may be required to
attach the cooler to the existing roof jack.
To assemble the roof jack adaptor, hold panels at 90 degrees
to one another. Align slots in upper and lower panels then slide
together.
INSTALLING THE ROOF JACK
ILL3363-A
ILL3363-A
Note! It is recommended that a strip of foam or sealant is
applied to the upper ange on the roof jack before securing the
cooler to provide an airtight seal.
Ensure that the top of the roof jack is level and square in all
directions (use a spirit level). This helps with levelling the cooler.
CONVEYING THE COOLER TO THE ROOF
ILL1667-A
Lifting and installing the cooler is made easier by removing the
pad frames rst. They can be replaced at the very end of the
installation procedure.
Do not slide the cooler, lift and carry it. It is recommended
that at least 2 people carry the cooler whenever it needs to be
moved. Do not drop the cooler. Always handle with care.
Important! For lifting or pulling purposes when using ropes or
slings, always apply the ropes around fan housing. Never tie
them to any or all of the 4 round corner posts.
WARNING! Take care that the ends of ladders, etc. don’t
penetrate into the opening of the cooler, as the Weatherseal or
the cut-o󰀨 plate may be damaged.
CAUTION! Never try to raise the cooler to the roof alone.
MOUNTING THE COOLER
Locate the cooler on the dropper with the tank (reservoir) sump
on the low (gutter) side of the installation.
ILL159-F
Fix the cooler to the dropper with 8 self-tapping screws provided
(2 screws per side). There are ten screw locations identied by
“V” notches. If access to the “high roof side” is limited, use 3
screws on each side and 2 on the front. In exposed or high wind
areas, seek advice from a structural engineer.
Important! Screw length must be less than 1.5” (40mm) to
avoid interfering with the weatherseal.
EXT

SECURING THE LEG SUPPORTS
The telescopic leg supports (with feet attached) slide up and
down inside the four corner posts. By removing the screw from
the lower end of the corner post you enable the leg support to
slide down to roof level.
ILL958-A
ILL958-A
Make sure each leg is vertical before securing. Secure foot to
roof with 2 screws (minimum).
ILL959-B
Maintain downward pressure on corner post as you replace the
screw to ensure that the bottom of the corner post is sitting ush
with base of corner support (view through “V” notch). Ensure
screw is horizontal when replaced.
ILL959-B
ILL960-A
ILL960-A
The support legs are not full weight bearing and are only
intended for additional support in case of high winds, etc.
ILL1649-A
ILL1650-A
ILL525-D
Check the Weatherseal moves freely and without obstruction by
lifting the latch and rotating counterweighted arm.
In the operating position it acts as a restrainer, preventing gusts
of wind from opening the Weatherseal. Once the cooler is
installed on the roof, squeeze the latch and rotate it clockwise to
its operating position.
(Model dependant, refer to Dealer.)
Where tted, the Weatherseal latch performs two functions.
In the locked position it acts as a latch, preventing movement
during transport.

INSTALLATION
Installation of the cooler water supply must conform to
local plumbing rules, regulations and standards.
The following specications for the cooler water
supply are required:
Water Connection ½” BSP
Min Water Pressure 15psi (100kPa)
Max Water Pressure 115psi (800kPa)
Min Water Flow 2.1 gallons/min (8 liters/min)
Max Water Temperature 104°F (40°C)
Important! If the water pressure exceeds maximum
specication then a pressure reducing valve is required and
must be supplied and tted by the installer.
WATER CONNECTIONS
A permanent water supply is required to be connected to the oat
valve inlet ttings leading into the cooler. The water connection
point is located on the underside of the cooler tank (reservoir).
You must install 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. DO NOT FIT SHUT OFF VALVES DIRECTLY ONTO
THE FLOAT VALVE NIPPLE.
WATER REQUIREMENTS
Important! In areas subject to freezing, the water supply line
to the cooler requires a drain down facility at the lowest point in
the water supply pipe.
Important! Flush the water pipe to remove any swarf before
nal tting. Swarf can lodge in the solenoid and oat valve,
preventing them from functioning correctly.
OVERFLOW & BLEED OFF FEATURE
A special "bleed-o󰀨" tting is supplied with the cooler. It has a
3-fold function: it acts as an overow, a drain and a bleed-o󰀨.
If the water level gets too high the excess water overows into
the tting and away to waste.
If the user wants to drain the tank (reservoir) he can lift the
tting out of the drain hole and the tank water will run away
to waste. The bleed function must always be commissioned,
except in areas where it is illegal to run water to waste.
The continuous bleeding of a small amount of water to drain
forces fresh water to enter the cooler and reduces the rate at
which salt and scale build up on the pads. The bleed-o󰀨 tting is
inserted into the large hole already formed in the tank.
Screw the tank nut rmly under the tank by hand.

8 |
The drain adaptor allows the attachment of a ¾" drain hose
to run water to a waste point. Attach it to the bleed tting
underneath the tank (reservoir) by using the drain nut.

The bleed rate can be varied according to local conditions.
With all the plastic plugs removed from the tray, minimum bleed
will occur. Insert plugs to increase the bleed rate to suit your salt
build up experience. See heading "Operating Adjustments" for
further details.
In those areas where draining of bleed-o󰀨 water is illegal, the
bleed must be disabled.
WARNING! In cases where bleed-o󰀨 is not used the pads will
require frequent inspection and replacement. Failure to do so
may cause water to leak into the building or onto the roof, which
may enter electrical components creating an electric shock or
re hazard. Where this condition is allowed to exist, Seeley
International (Americas) accepts no responsibility for any
damage or injury that might occur.
SETTING THE WATER LEVEL
WATER LEVEL ADJUSTMENTS
The water level in the cooler is important. Adjust the level at the
oat valve inside the cooler. Rotate the large plastic oat CCW
or CW to change the level. CW will lower the level; CCW will
raise the level.
NEVER ADJUST THE WATER LEVEL WITH THE COOLER
RUNNING because the residual water in the pads and pipes
will cause the water to over ow when it runs back into the
tank.
ILL188-C

Installation of the cooler must conform to local electrical rules,
regulations and standards.
Important! It is a requirement of Seeley International that
all Breezair coolers be connected to a dedicated circuit to
the distribution board, with a separate circuit breaker and
incorporate all pole disconnection switch in accordance with the
local wiring rules.
Electrical supply specications may vary depending on model
or region. Please refer to the rating label attached to the cooler
for details.
WARNING! If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or a similarly qualied
person in order to avoid a hazard.
WARNING! When retro-tting the cooler to an existing
installation always turn o󰀨 the electrical power at the source of
the wiring. DO NOT TAKE RISKS! Turn o󰀨 and tape over the
circuit breaker or remove the fuses and keep them with you
until the job is complete. Set cooler, isolator switch, wall switch,
motor and pump to “o󰀨”. Be sure to tell other occupants of the
building what you are doing.
The point of entry into the cabinet of the cooler is by knockouts
in the tank (reservoir).
Seal the gap between the conduit and the knock-out hole with
silicone sealant after making connections and clamping the
conduit cable.
Important! Ensure that all electrical connections are tight.
Loose connections will cause overheating that may lead to
machine damage or re.
Replace all covers on completion of work, using only the screws
supplied.
Do not tamper with factory wiring. Before leaving the job,
a trained, licensed technician must check that the cooler is
operating correctly.

INSTALLATION
Wiring to the cooler must be rated at cooler rated amperes
or higher, and must be protected by a suitable fuse or circuit
breaker. Cables are to be double insulated all the way into the
cooler junction box.
Ensure that all electrical connections are tight. Loose
connections will cause overheating that may lead to machine
damage or re.
Replace all covers on completion of the work, using only the
screws supplied.
DO NOT TAMPER WITH FACTORY WIRING.
Before leaving the job, a trained, licensed technician must
check that the cooler is operating correctly, and must set
the motor full load amps using a clip-on ammeter. Make this
adjustment at the motor pulley (sheave). See later detail under
heading "Operating Adjustments".
The Power Pack tted in this cooler contains a junction box with
main power supply termination box attached.
Connect the power supply and control cables inside this
termination box as shown on "WIRING DIAGRAMS" on Page
9.
The junction box is factory sealed; do not attempt to open it;
there are no eld serviceable parts inside.
The junction box contains plug receptacles for fan motor, water
pump, and other optional features if used.
Fan motor amperes must be adjusted before closing the
termination box using a clip-on ammeter on the power wires.

INSTALL AND OPERATION MANUAL EXT |11
INSTALLATION
Important: Install all the pad frames except the one on the
motor side.
Ensure that all intended doors, windows or other means of
exhaust are open in the building, and that all outlet grilles are
open fully.
WARNING: Beware of rotating fan, belt and pulleys whilst
making adjustments to motor speed, pulley or belt tension
settings. Ensure the cooler is switched OFF via the electronic
module isolation switch whilst working inside the cooler.
Set the cooler running at the highest speed for about 10
minutes, or until the motor has reached its normal operating
temperature (hot!).Motor load must be checked without the
pump running.
Clip your ammeter onto the free cable in the main termination
box. This should be done by a trained licensed electrician.
MOTOR POWER (AMPS)
ILL1013-D
For convenience, the rated motor current, in amps, is printed
on a small label attached near the cable fork (in addition to the
normal motor nameplate label located at the back of the motor).
Check the measured amps against the motor nameplate amps.
If the measured amps are less than the nameplate amps the
adjustable motor pulley sheave must be altered to increase the
fan speed, thereby delivering the full capability of the cooler to
your installation. The measured amps must be equal or close
to, but never more than the nameplate amps. (see heading
“Pulley Adjustment”)
If the measured amps are greater than the motor nameplate
amps the fan MUST be slowed down by adjusting the motor
pulley sheave in the opposite manner. Failure to do this will
cause overheating in the motor and may cause the motor’s
thermal protector to trip.
Replace all covers when adjustments are completed using the
screws provided.
A = Fixed Sheave
B = Grub Screw
C = Adjustable Sheave
D = Locking Cap
E = Locking Cap Screw ILL1208-D
The outer half of the pulley is on a thread and can be moved in
or out by removing the locking cap and then turning the outer
half by hand in the desired direction.
When an adjustment is made, replace the locking cap, aligning
the screw hole with the nearest hole in the adjustable half. Lock
it into place with the securing screw. Ret the belt, reset the belt
tension, then run the cooler and check the amps. Repeat the
process until the amp level is set.
You can start and stop the cooler for this procedure by using the
isolating switch inside the cooler.
PULLEY ADJUSTMENT
The motor pulley is adjustable in order to set the motor amperes
at the correct (nameplate) level, and thus provide the owner
with full machine cooling capacity.
DO NOT USE THE PULLEY ADJUSTMENT TO SET BELT
TENSION
The adjustment is made with the cooler switched OFF. Never
attempt this procedure with the cooler operating.
• Remove the drive belt.
• To increase the fan speed (and therefore the motor amps),
the two halves of the pulley must be closer together, ie: turn
the adjustable half clockwise.
• To decrease the fan speed (and therefore the motor amps),
the two halves of the pulley must be further apart, ie: turn the
adjustable half counter-clockwise.

RESETTING THE PUMP CIRCUIT BREAKER
1. Disconnect power supply at the main panel.
2. Remove the junction box from the blower housing.
3. Invert the junction box and locate the circuit breaker.
4. Press the button until it "clicks" and remains in.
5. Reposition the junction box on the blower housing
(ensure locking screw is reinstalled.
Should a 2 speed motor overload, one of the circuit breakers
will trip, showing a white button. To reset, press this white
button until it "clicks" and remains in.

BELT TENSION
Belt tension is important! If it is too tight there will be
excessive belt and bearing wear. If it is too loose there will be
belt slip, excessive belt wear and loss of cooler performance.
There are two adjuster bolts with locking nuts attached to the
motor mounting.
The tension should be adjusted so that the deection on one
side of the belt is 5/8” to 13/16”.
To make the adjustment, loosen the locking nuts and screw the
bolts in or out as required to change the belt tension. Re-tighten
the locking nuts.
It is important to recheck the motor amps again after re-setting
the belt tension.

Correct belt tension ensures the belt will not slip. Check the
temperature of the belt by hand after each adjustment, by
turning o󰀨 the cooler and holding one side of the belt in your
hand. If the belt is warm to touch, it is slipping!
Continue to tighten until it runs cool.

See previous heading "Overow and Bleed-O󰀨 feature" under
"Water Installation".
Adjusting the bleed rate is necessary to reduce the salt deposit
on the pads. Salt deposit can NEVER be entirely eliminated,
only the rate of deposit can be changed. The bleed feature
causes some salt concentrated water in the tank (reservoir) to
be drained away. Fresh water enters the cooler automatically as
the salty water exits.
The rate of bleed will vary according to water quality, but should
be set to a minimum rate as set out below:-
EXT155 (small cabinet): 0.08 gpm
EXT265 (large cabinet): 0.13 gpm
NOTE! Bleed adjustment cannot be precise as operating
conditions vary continually.
NOTE! Previous warning about running coolers without bleed-

COOLER OPERATION
HELLO AND CONGRATULATIONS ON PURCHASING
A SEELEY EVAPORATIVE COOLER
At Seeley International we manufacture evaporative coolers
from the highest quality materials, and we have designed the
product to provide many years of economical, trouble-free
cooling.
USING YOUR COOLER
Evaporative air coolers always function on 100% fresh outside
air. Therefore you must either open doors and windows, or,
provide exhaust outlets in the building.
FAILURE TO PROVIDE ADEQUATE EXHAUST OPENINGS
WILL CAUSE A BUILD UP OF HUMIDITY INSIDE THAT WILL
BECOME VERY UNCOMFORTABLE.
To provide e󰀩cient cooling or ventilation the building must have
su󰀩cient exhaust openings to the outside of the building.
To assist air ow, open windows and doors that are farthest
from the outlet vent in each room. In these rooms, provide an
exhaust opening 2 times the vent size of the room.
Where the design of the building prevents adequate exhaust,
consideration should be given to the provision of mechanical
extractions, such as an exhaust fan.
There are three main ways that an evaporative cooler can
operate to provide cooling comfort.
• The cooler can be set to cool at a constant fan speed, without
reference to the current temperature.
• The cooler can be given a temperature target, in which case it
will vary the fan speed in order to get as close to the target as
possible. (Note! Dependant on controller installed.
Note! Humid weather conditions may limit the temperatures
that can be achieved).
• The cooler can be set to a fan only mode, providing air
circulation only.
START UP
• Turn on the water supply and make sure the shut o󰀨 valve
at the cooler is also on.
• Turn on electrical power supply.
• Wait a few minutes for the water to ll the cooler tank.
• Turn on "cooling" at the wall control to start the pump and
pre-wet the pads.
• Turn on the fan to High or Low speed as desired.
• In humid weather you may feel more comfortable by turning
o󰀨 the cooling to run the fan only.
• You can create your own pattern of air ow in the building
by adjusting the outlet vents and doors and windows to
direct the air where you want it.

INSTALL AND OPERATION MANUAL EXT |15
MAINTENANCE
Maintenance Schedule servicing is essential to ensure the
cooler operates e󰀩ciently for many years. It must be carried out
by a qualied, licensed service technician.
It is important to note that all evaporative coolers have
components that may need periodic replacement (eg. lter
pads, hoses, o-rings etc).
Note! It is important that only new Seeley International factory
authorised replacement parts be used in this cooler. Failure to
do so may result in voidance of the factory warranty, improper
cooler and unsafe operation.
For detailed servicing requirements refer to the Maintenance
Schedule section.
Note! Failure to carry out the Maintenance Schedule services
will void your warranty cover.
While installation is not covered by warranty (e.g. duct work,
roof penetrations, electrical and water connections etc.), these
items should be checked as they can a󰀨ect the performance
(and/or safety) of the cooler. For this reason they are included in
the Maintenance Schedule.
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
(e.g. AS/NZ 3666.2:2011).
ACCESS FOR SERVICING AND MAINTENANCE
WARNING! As your cooler is mounted on the roof, we
suggest that any maintenance or checks be carried out by
an authorised Seeley International dealer or service agent.
Climbing onto the roof can be hazardous and could result
in injury to you and damage to your property.
Working at heights requires additional safety precautions.
Required clearances around the cooler for maintenance and
servicing are shown below.

Specic job sites may incur additional charges for servicing in
order to provide safe access to the cooler for servicing, which
may include, but not limited to sites:-
• with a roof pitch >30°
• with limited access to the roof
• where roof material or the condition of does not allow safe
access
• where the roof access point is > 13’ (4m) above ground
level
• where the cooler is located too close to a fall edge
• which are not structurally capable of supporting the weight
of the cooler and service technicians
Extra service or warranty charges may apply for the cost of
any equipment or additional labour involved in providing
safe access to the cooler.
