To provide efficient cooling or ventilation the
building must have sufficient exhaust open-
ings to outdoors in the form of doors, win-
dows or other vents. To assist air circulation,
open windows or doors that are furthest from
the outlet vent in each room. In every room
that has an outlet vent, provide an exhaust
opening about 2 or 2.5 times the vent size of
the room. Where the design of the building
prevents adequate exhaust, consideration
should be given to the provision of mechani-
cal extraction such as an exhaust fan.
EFFECTIVE COOLING
Congratulations on choosing a new cooler
for your home.
Your cooler is built from the highest quality
materials and engineered to provide many
years of economical, trouble free cooling.
Please take a few minutes to read these in-
structions so you have a full understanding
of how to operate your cooler. Your installer
should demonstrate the features and proce-
dures set out in these instructions. The in-
staller should also provide you with a Model
and Serial number, which can be filled out
on the last page.

The ON/OFF button turns the cooler on and
off.
There are two modes of operation to choose
from, Automatic mode or Manual mode. When
the cooler is turned on, it will start in the mode
of operation it was in when last turned off.
If your cooler has not been operated for a
while, then when you start it, “Pre Cool Cycle”
may sometimes flash on the display as shown.
This indicates that the water pump will oper-
ate to saturate the cooling pads for a few min-
utes before the fan is turned on. This is to
ensure that when the fan starts, only cool air
enters your home.

culate through your home.
AUTOMATIC MODE
The AUTO button switches between Automatic
mode and Manual mode. When “Auto” is dis-
played the cooler is under Automatic control
and will operate according to the temperature
sensed at the thermostat.
When the cooler is turned on, it will read the
temperature and set the cooler operation ac-
cordingly. If the temperature increases at the
thermostat, then the fan speed will increase.
As the temperature decreases the fan speed
will decrease until the cooler turns off.

USING THE COOLER
You can experiment with the settings
on your thermostat. This is the best
way to get the most from your cooler.
With the cooler running in Automatic mode,
you may find that you are too cold or that the
cooler is blowing too much air. Press ▼to
lower the automatic temperature setting and
reduce the amount of cooling.
If you are too cold with the cooler running in
Manual mode, then press ▼ to reduce the
fan speed. You can also circulate fresh
uncooled air by pressing COOLCOOL
COOLCOOL
COOL until “Vent”
displays.
You may find that with the cooler running in
Automatic mode, you are not cool enough.
Simply press ▲to increase the cooling rate.
Now that you have read these instructions,
press ON/OFFON/OFF
ON/OFFON/OFF

utes to complete. After this time, the fan will
come on automatically, and you can enjoy
the comfort of cool fresh air!

During operation, the standard bleed system
will drain small amounts of water. This ensures
fresh water is continually added to dilute salt
accumulation in the water caused through
evaporation. This helps keep the cooler in good
condition and ensure optimum performance.
The bleed rate will depend on local operating
conditions and will be set by the installer.

STANDARD BLEED SYSTEM
AUTOMATIC DRAIN VALVE
This cooler comes with a standard bleed sys-
tem or the optional automatic drain valve. If the drain valve was installed instead of the
standard bleed system then your cooler will au-
tomatically drain after a set time of continuous
operation. This ensures the water is always fresh
and helps maintain your cooler in good condi-
tion to ensure optimum cooling performance.
The frequency of the automatic drain may have
been adjusted by your installer according to the
general water quality in your area.
When the cooler is turned off for 72 hours,
the drain valve will open automatically and
empty water from the cooler. When the cooler
is turned on again, fan operation will delay
for a few minutes while the tank refills and the
cooling pads are saturated again.
At any time when the thermostat is OFF, you
can drain the cooler by pressing and holding
▲and ▼for 1 second.The display will show
“dr” to confirm the operation has activated.

MAINTENANCE
Regular maintenance is essential to ensure the
cooler operates efficiently for many years. Ser-
vices must be performed before and after the
summer season. More frequent servicing may
be required in dusty conditions or in areas with
poor water quality.
We recommend maintenance is car-
ried out by an authorised Dealer or
Service Agent. Climbing onto and
working on the roof can be hazard-
ous and could result in personal in-
jury or property damage. Failure to
carry out maintenance will affect your
warranty coverage.
WARNING
END OF SEASON SERVICE
Please note that some State regulations re-
quire evaporative air coolers to be serviced
at specific intervals.
HEALTH REGULATIONS

MAINTENANCE
•Turn off the power supply to the cooler
•Remove the pad frames as shown.
•Ensure the power switch in the cooler is off.
•Gently wash the pads to remove any dust
build up during the winter period. If the pads
are in poor condition, replace them.
IMPORTANT: Do not damage the pads
with high pressure water spray.
•Replace the bleed system if it was removed
during previous maintenance and ensure the
o-ring is fitted. (If fitted with a drain valve this
will not be necessary as it will automatically
close when the cooler is turned on).
•Turn on the power switch inside the cooler.
•Turn on the water and then the power.
•Re-fit the pad frames and run the cooler.
PRE-SEASON SERVICE
Take hold of the pad frame and pull it towards
you until the internal side clips disengage.
To remove a pad frame, insert a flat screw
driver tip into the slot as shown and lever until
disengagement occurs.
REMOVAL OF PAD FRAMES
Do not run the cooler with the pad
frames removed.
