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 is 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. 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.
