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.
F ILTER P ADS
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. Do not hose Celdek with high pressure.
U NIT W ATER R ESERVOIR
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 unit reservoir.
W ATER L EVEL / F LOAT V ALVE
The water level should be set at nominal 30-35mm from the top of the overflow. 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. Turn
the water off. 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. Adjust float valve.
M OTOR AND F AN
Check that the fan spins freely and that there is no build up on the blades.
E LECTRICAL
No general maintenance is required to the electrical system.
A Qualified Electrician should only carry out electrical connections and maintenance.
B LEED O FF
The bleed rate should be checked to ensure it is adequate and that there is no build
up of mineral deposits in or on your air conditioner. White deposits indicate high
mineral content and the Bleed Rate should be increased. If it is at maximum and the
deposits are still forming, then more regular maintenance is required.
P UMP
Check the pump spins freely and that the strainer is clean.
