.
All Ducted Evaporative Air Conditioners benefit from 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.

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.

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.

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.
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.
