OPERATING INSTRUCTIONS
U SING YOUR A IR C ONDITIONER
Evaporative Air Conditioners must always function on 100% fresh outside air.
Therefore they require you to open or provide exhaust outlets in the space being cooled.
Such outlets may be provided by the opening of doors and/or windows in various rooms or
sections. They may also be provided by the installation of special exhaust grilles through
doors, walls or into the ceiling (attic) space of the building.
Where the building does not allow such easy exhaust provisions, there must be some kind of
mechanical ventilation installed, such as an exhaust fan which can extract approximately
80% of the air that the air conditioner is discharging.
Never allow conditioned air to exhaust into a closed space, it must always be allowed to
exhaust to the outside.
Generally, the higher the relative humidity, the higher the air quantity required from the air
conditioner. You should therefore control the speed of your air conditioner accordingly. On
very dry days the air conditioner will give maximum cooling and this will decrease as the
humidity increases.
The air distribution system in your building has been fitted with air outlet grilles and they
probably have adjustable louvre blades. You can adjust the blades yourself to create your
own pattern of air distribution in the space.
If you close the louvres too much you may get undesirable air noise.
O PERATING I NSTRUCTIONS
Turn on the water supply at the source and
make sure that the water isolation valve at
the unit is also turned on.
Turn on the electrical power at the source
and make sure that the isolating switch
outside the unit is turned on.
Turn COOL switch on.
It is recommended that you wait 10 minutes
for the pump to saturate the filter pads. A
longer period may be required where a dump
valve is fitted.
Select LOW fan speed, using the switch on
the control panel inside the building, then
switch unit ON. (It is recommended to start
the unit on LOW speed, and then switch to
HIGH if required).
At times, when the outside humidity is very
high, you may feel more comfortable using
ventilation system only. For ventilation
system only, turn the COOL switch off and
run the fan only. The fan speed can be
selected as described above.
Follow the above instructions about providing exhaust opening in the building. This is very
important. When unit is turned OFF the COOL switch should also be turned OFF as the
pump is independently switched.
