Before starting any maintenance work on your unit, ensure it is disconnected
from the power supply.
Note:
It is essential that your evaporative air conditioner is maintained in accordance with this manual. Fai-
lure to do so will affect the life of the product and reduce the level of efficiency.

General
Filter Pads
Visually check Filter pad for damage or blockage. Gently hose down pad from both sides to remove any
build up of salts, dust and pollen. In dusty areas more regular cleaning is recommended. Check the water
distributor, making sure it is clear and free from blockage. Failure to do so may lead to uneven water distri-
bution and therefore less efficient operation.
Water Tank
It is important to keep the water tank clean and free from sediment and algae growth. Using a small soft
bristle brush, brush all surfaces in the tank while it is full of water . Turn off the water inlet to the unit (an
isolation valve should be fitted to the water inlet before the float valve or at the water supply faucet). Drain
the tank by removing the drain plug and afterwards replace the drain plug and open the water valve. After
refilling, it may be necessary to repeat this procedure if the tank is very dirty.
Water Distributor
Check the water distribution system for blockage in top.
Note: Water supply line to float valve must be flushed before connecting.
Water Level / Float Valve
The water level should be set at nominal
(19mm) below height of stand pipe lip. The float valve is a me-
chanical type. Make the adjustment bending the rod tight as position marked bellow. If the valve is leaking,
it may require replacement.
Note: Water supply line to float valve must be flushed before connecting.
Note: Some discharge from the overflow may be experienced after shut down due to water draining
back from the filter pad. This is normal.
