Maintenance

General

Filter Pads

Visually check CELdek® pads for damage or blockage. Gently hose down pads 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 distribution 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 (DO NOT FORGET THE PUMP
STRAINER). 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 undoing the external overflow fitting lock
nut and removing the overflow fitting. 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. Check the delivery tube for kinks or holes.
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 (¾") below height of stand pipe lip. The float valve is a
mechanical type and is factory set. If it requires adjustment keep bends tight. 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 CELdek® filter pads. This is normal.
Motor and Fan
Check that the fan spins freely and that there is no build up on the blades. Check the motor for corrosion
and spray with an anti-corrosive agent if necessary.
