TING INSTRUCTIONS
The principal of your unit is to introduce fresh air, which is washed through the filter pads to
provided cool fresh air. The air is exhausted taking with it any heat loading on the space.
Evaporative Air Conditioners must always function on 100% fresh outside air.
Exhaust / Air Relief
Evaporative air conditioners 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. Air exit areas
should be at least 0.5 square meters per 1000 litres of air.
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.
When deciding on an exhaust point using doors, windows or louvred vents, always keep the
opening options closed on the windward side of the building.
General Operation
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.
