SAFETY
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 offer 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 dif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.

COOLER LOCATION
Check 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:
• 3m from a solid fuel heater ue,
• 1.5m from a gas ue,
• 5m from a sewer vent, and
• 600mm from a wall.
The cooler must be mounted at least 3m (preferably 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?

To separate the transition from the pallet cut off the front
tabs and the rear ap.
Note! These two pieces of timber will form a height
gauge to ensure the nished cooler is correctly
positioned.
Note! Some nails protruding from the timbers may
be added to help locate them. For roof slopes greater
than 45° add 15mm packer to top gauge.
PREPARING THE DROPPER
Cut a 50mm diameter cable exit hole in the dropper then
t and screw the cable grommet into position. Locate the
hole so the cables will not interfere with the operation of
the weather damper.
Before transporting to the roof, temporarily screw the
transition to the dropper using a screw in each corner.
Afx gauge timbers under the top and bottom edges
of the transition with 30mm screws supplied
Keep the pallet to create a gauge for locating the
transition piece and dropper.

The installer must ensure the dropper is suitable, and is
secured adequately for wind conditions at the site. Additional
restraints may be required if the cooler is more than 200mm
higher than the roof timbers, or design wind velocity at the site
exceeds 43m/s.
In exposed or very high wind areas use 16 screws, minimum
shank diameter 5.2mm to secure the dropper. In areas subject
to cyclones or where the cooler is located more than 8m above
the ground seek advice from a structural engineer.
Important! Ensure the weather damper operation is not
hindered by the attaching screws.

Fit & secure the transition to the top of the dropper,
repeating the same xing rationals for exposed, high
wind areas, cyclones etc.
Important! The ashing should go up, but not higher
than 20mm above the bottom of the transition and may
not add more than 7mm girth to the dropper including
fasteners. This ensures a neat installation.
The dropper may now be ashed to the roof. Make sure there is
no chance of water entering the roof space.
Install the dropper and securely x it to the roof structure on 3
sides. This may require the addition of extra structural timber.
MOUNTING THE DROPPER
Important! The dropper must never sit directly on any ceiling
joists or beams, as this may cause noise or vibration issues,
and possible ceiling damage.
LEVELLING THE DROPPER / TRANSITION
Ensure the top of the dropper (or transition for EZQ model) is
level and square in all directions (use a spirit level). This helps
with levelling the cooler.
ILL2129-A
Ensure duct insulation is rmly held in against the duct.
SECURING THE DROPPER & TRANSITION
Place level vials in side wells provided in the transition.
Pivot the transition/dropper off the appropriate gauge
timber (top or bottom) until the level reads true. Hold
dropper in place using one single screw into the rafter.
This will set dropper at an angle of 24°. Check for lateral
level by placing level vials in top or bottom wells.
Note!
Very few roof slopes will contact both gauge timbers
once the dropper is properly levelled. As a general rule:
• For roof angles less than 26°, only the bottom gauge
will apply.
• For roof angles greater than 26°, the top gauge will be
used.
This will be apparent when checking for level via the
level vials.
Note! The height gauges are intended to work off the
top nominal surface of the roof. Uneven roof surface
e.g. Tiles may require some packing up.
Once the dropper is secured, remove the gauges and
transition so that the dropper can be sealed.
SEALING THE DROPPER

BREEZAIR EXQ/EZQ/EXS EVAPORATIVE COOLERS INSTALLATION MANUAL |9
MOUNTING THE DROPPER cont
For EXQ/EXS model, x 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 40mm to avoid
interfering with the weather damper.
EXTRA NOTES FOR EZQ MODEL ONLY
ILL1667-A
ILL1420-B
ILL159-F
MOUNTING THE COOLER
Before mounting the cooler on the dropper, release the mains
power cable from the hook under cooler. Feed the cable down
into the dropper.
Locate the cooler on the dropper with the tank sump on the low
(gutter) side of the installation.
Also remove the lower pads, as they may fall out when
transporting the cooler to the roof.
CONVEYING THE COOLER TO THE ROOF
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 weatherdamper
or the cut-off plate may be damaged.
CAUTION! Never try to raise the cooler to the roof alone.

Check the weatherdamper 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 weatherdamper. Once the cooler is
installed on the roof, squeeze the latch and rotate it clockwise to
its operating position.
The weatherdamper latch performs two functions. In the
locked position it acts as a latch, preventing movement during
transport.
Important! Ensure that the four Tab Screws (which are
removed to separate the transition from the cooler) are
re-tted behind the tabs, after the cooler has been tted
into position.
Carefully lift the cooler onto the transition piece and
lower downwards ensuring all nine clips have engaged.

INSTALLING THE CONTROLLER CABLE
Connect one end of the MagIQtouch Controller cable (with
ferrite suppressor) to the cooler electronics box.
Feed looped end of the controller cable (A) through the “wedge
shaped” knockout and into the dropper.
Important! Ensure cables do not interfere with the
weatherdamper.
Note! It is important to route both cables out through the
dropper grommet before tting ductwork.
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 a separate isolation switch in accordance with the
local wiring rules.
A 10A socket outlet within one metre of the dropper’s cable exit
hole is required.
The following specications for the cooler electrical supply are
required:
240V / 50 Hz Single Phase
WARNING! If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly qualied
ELECTRICAL REQUIREMENTS
Installation of the cooler water supply must conform to
local plumbing rules, regulations and standards including
AS/NZS 3500.1
The following specications for the cooler water
supply are required:
Water Connection ½” BSP
Min Water Pressure 100 kPa (15 psi)
Max Water Pressure 800 kPa (115 psi)
Min Water Flow 8 litres / min
Max Water Temperature 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.
Harmony & Horizon
For Coolers with the inlet solenoid valve tted, the water
connection is a 1/2” BSP compression tting on the end of a
exible hose. This can t directly onto the water pipe or be
screwed directly onto the manual water shut-off valve. Always
ensure that the water pipe connection does not place sideways
strain onto the oat valve.
Homemaker
A permanent water supply is required to be connected to the oat
valve. The water connection point is located on the underside
of the cooler. The water connection tting is a 1/2” BSP male
adaptor suitable for a compression tting. Do not t the manual
water shut-off valve directly onto the plastic nipple. You must
install a manual 1/4 turn ball type shut off 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.
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.

INSTALLING THE INLET SOLENOID
For coolers tted with a drain and solenoid valve, it is a
requirement to t the new detachable hose set supplied.
Any old hose sets should not be re-used.
For EXQ/EXS model cooler, t the inlet solenoid under the tank
as shown:
Ensure washers are correctly located. Do not over tighten
plastic ttings.
Insert the solenoid cable through the hole in the cooler tank
(behind the drain valve) and connect to the water solenoid
valve. Make sure the cable is tted to the groove underneath
the tank so it does not get trapped by the solenoid cover when
tted. The cable leads can be connected to the solenoid either
way around.
Important! The cable must wrap underneath the solenoid.
Fitting the Solenoid Cover:
Once the solenoid valve and its cable has been tted, place the
cover over the assembly. Make sure the solenoid valve cable is
retained in the groove in the cooler tank. Secure the cover by
tightening the exible hose assembly nut (C).
Important! Make sure the cable cannot lay in the water at
any stage.
Connect the electrical leads to the solenoid. The electrical
cable leads can be tted either way around.
Fitting the Solenoid Cover:
Once the solenoid valve and its cable have been tted,
place the cover over the assembly. Ensure that the cover
does not touch the solenoid. Also make sure the solenoid
valve cable is retained in the groove in the cooler tank.
Then secure the cover at each end, with the two screws
supplied.
Important! If freezing conditions can occur at any time, a
drain down facility must be provided at the lowest point of
the water supply pipe.
Taps or shutoff valves used must not be of the non-return
type.
Fit the inlet solenoid under the tank as shown.
Release the coiled up solenoid cable then remove the
overow cap. Pass the cable down and out of the overow
pipe. Ret the cap, ensuring the cable is located in the
groove in the cap.

Fit the bleed tray as shown:
Screw the nut up tightly by hand underneath the cooler.
Do not overtighten.
Note! Make sure the bleed tray is correctly oriented (the bleed
tray must sit underneath the Chillcel pad when it is tted) and
that the o-rings are tted before placing the threaded bush into
the hole.
The bleed rate is controlled by the number of plugs that are
inserted into the tray. The more plugs inserted, the more water
will bleed off.
Important! For Homemaker models, the water probes and
inlet solenoid cable must be removed and discarded. The
supplied shorting plug must be tted to the electronics module
(before the power is turned on), where the water probes were
connected (A).

The oat valve will eventually stop the water from entering the
cooler. Wait for this to happen and check the water level.
ILL1827-B
ILL1825-A
If the level is too high rotate the oat clockwise. Drain some
water from the tank and allow it to rell to the new set point. If
too low rotate the oat in an anti-clockwise direction.
TESTING THE DRAIN VALVE
The drain valve can also be tested from the “Service Operating
Screen”.
Set DRAIN to ON to energise the component and close the
drain.
Set DRAIN to OFF to open the drain.
Alternatively, the “Manual Drain” option in the COOLER
SETTINGS menu can be used.
REFITTING THE PAD FRAMES
Ret the pad frames by locating the bottom edge in the tank
groove, then push the top in under the lid.
Ret the corner clips after replacing the pad frame(s).
It is advisable to check the water level again after the oat valve
seal has “bedded in”.
Once the water level is correct, isolate the control box and
reconnect the pump plug.
Look for a moulded triangle shape marking in the tank.
EXTRA NOTES FOR EZQ MODEL ONLY
Scroll down and select the “Service Operating Screen” feature.
This will open a screen which allows direct control of the fan
and all water components for testing and troubleshooting
purposes.

PAD FRAME POSITIONS
When re-tting pads, ensure that they are tted in their
original positions. EXQ210, EZQ215 and all EXS model
coolers have pads that vary from the standard 90mm thickness.
While removing the pad frames, take note of the location each
belongs to.
Check for stickers indicating correct locations for thick or
cut edge pads.

Water Manager
Select the preferred water management method:
• Salinity Measurement - replaces water when Salinity level
reaches set point.
• Timed Drain - drains Tank After 8 tank ll cycles or every
1-2 hours (system dependant).
• No Drain Control - salinity control external to electronics
eg. continuous bleed.
• No Water Thermostatic - allows Thermostatic control in
VENT mode. No water present. Cooling performance is
limited.
Weather Seal Open Speed
The cooler fan will turn on at the specied weather seal opening
speed for the rst 10 seconds each time it starts up. It will then
return to the set fan speed.

Sets the time delay before the drain valve opens after the pump
in the cooler is turned off.
Autoclean
Select the preferred cleaning interval (50 / 100 / 200 hours).
At 8.00am after the selected running hours has been reached,
the cooler will drain the tank, ll with fresh water and operate
the pump for 5 minutes. When complete, drains the tank and
returns to previous operation mode.
Stickers adhered to the fan scroll indicate the correct position.
If tted incorrectly they may cause problems:
• Thicker pads may catch on internal components causing
damage.
• Thicker pads may impede the correct operation of the oat
valve.
• Incorrect positioning of pads may cause a drop in cooler
performance.
• Incorrect tment may allow water to bypass the pad and be
carried over into the air stream and ducting.
• Water bypass may cause damage to internal electronic
components.
TESTING THE PUMP
Test the pump by turning the cooler on at the MagIQtouch
controller, in “COOL” mode. Check that water is evenly
distributed to all pads.
ADJUSTING COOLER SETTINGS
Within the SETTINGS menu of the MagIQtouch Controller is
the COOLER sub-heading. Here various settings of the cooler
can be adjusted.
Before tting the 4 main pad frames, make sure the 3 lower
pads are retted into their respective positions in the base
of the cooler.
To ret the pad frame, locate the bottom edge in the tank
groove, then push the top in under the lid. The frame
should clip into the cooler with a rm push of the hand at
the two points where the screwdriver was used. Remember
to insert the corner clips after replacing the pad frame(s).
