Unit Maintenance
Warning : Before commencing any maintenance work on your unit, isolate the power at the
supply (Fuse Box).
Note: It is essential that your evaporative air conditioner be maintained in accordance with this
manual. Failure to do so will effect the life of the product and reduce the level of efficiency.
Filter Pads
Visually check CELDEK pads for damage or blockage. 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. To clean the tank, use
a soft brush or similar. Wipe 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). Drain the tank by removing the 40mm standpipe. It may be necessary to repeat this
procedure if the tank is very dirty.
SAFETY: Wet roofs are dangerous – Take Care When Draining Tank.
Water Level / Float Valve
The water level should be set at nominal 65-70mm from the top of the overflow before filter pads are
saturated. After run off from operating filters the level from the top of the overflow fitting should be 25 –
30mm. The float valve is a mechanical type and is factory set. If it requires adjustment keep bends tight. If
the valve is leaking the seal may require cleaning or replacing. Isolate the water. Remove the split pin and
then float arm. Remove piston and clean or turn seal. Flush system and replace piston, float arm and split
pin.
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 pads. This is normal.
Motor and Fan
Check that the fan spins freely and that there is no build up on the blades.
Electrical
No general maintenance is required to the electrical system.
A Qualified Electrician should only carry out electrical connections and maintenance.
