Before starting any maintenance work on your unit, ensure it is disconnected
from the power supply.

General
Filter Pads
Visually check Filter pad for damage or blockage. Gently hose down pad 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. Using a small soft
bristle brush, brush all surfaces in the tank while it is full of water . Turn off the water inlet to the unit (an
isolation valve should be fitted to the water inlet before the float valve or at the water supply faucet). Drain
the tank by removing the drain plug and afterwards replace the drain plug and open the water valve. After
refilling, it may be necessary to repeat this procedure if the tank is very dirty.
Water Distributor
Check the water distribution system for blockage in top.
Motor and Blower Wheel
Check that the blower wheel spins freely. Check the motor for corrosion and spray with an anti-corrosive
agent if necessary.
Pump Operation
Check the pump spins freely and that the strainer is clean.
After a long idle period, the pump may stop rotating due to a mineral build up on the stainless shaft
adjacent to the motor. To free the pump shaft, remove mineral build up and rotate the shaft using fingers
or suitable sized pliers.
Spraying the area with suitable water displacement lubricate (such as WD-40®) may assist
