Ducted Evaporative Air Conditioning
DUCTED EVAPORATIVE AIR CONDITIONER MAINTENANCE
G ENERAL
All Ducted Evaporative Air Conditioners require some general maintenance to ensure continued cooling
efficiency and a long life. Maintenance is carried out at the beginning and end of summer to start up and
close down your unit.
We recommend that all maintenance work be undertaken by our fully trained and accredited Service
Technicians or an authorised Climate Technologies Service Provider.
The frequency of general maintenance will depend on local operating conditions such as water quality, air
borne dust and pollen.
It is essential that your evaporative air conditioner is maintained in accordance with this manual. Failure to
do so will affect the life of the product, reduce the level of efficiency and may void warranty.
For service Australia wide refer to the details on the service section of this manual.
NOTE: The manufacturer and its agents reserve the right to refuse service unless safety and accessibility
to the unit can be guaranteed. The cost of any extra equipment required to provide access to the
unit for servicing is the responsibility of the owner.
SAFETY: Prior to commencing any maintenance isolate the unit at the power source. Ensure the
roof is safe to access, your ladder is securely positioned and use suitable safety
equipment.
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.
W ATER T ANK
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. It may be necessary to repeat this procedure if the tank is very
dirty.
SAFETY: Wet roofs are dangerous – Take Care When Draining Tank.
W ATER L EVEL / F LOAT V ALVE
The water level should be set at nominal 65-70mm before filter pads are saturated. After run off from
operating filters the level should be 25 – 30mm from the top of the Aquamiser overflow. The float valve is
a mechanical type and is factory set. If the valve is leaking, the seal may require cleaning or replacing.
Turn of 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.
