Maintenance

Bleed Off

The bleed off should be checked to ensure it runs continuously and that there is no buildup of mineral
deposits in or on your air conditioner. White deposits indicate high mineral content and the bleed off
system should be checked. Should the bleed nozzle become blocked, use a fine pin or similar to clear.
If the bleed is running as per normal, the bleed nozzle is clean and the deposits are still forming, then
more bleed may be required.
In areas of poor water quality (where total dissolved
solids are greater than 300 p.p.m.) increase the diameter
of the bleed nipple using a 1.6mm (1⁄16") drill bit.
Pump Operation
Check the pump spins freely and that the strainer is
clean. Ensure the water slinger washer is in place on the
stainless steel shaft under the motor above the water
line.
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. See diagram.
Spraying the area with suitable water displacement
lubricate (such as WD-40®) may assist.
In areas of low voltage, the pump may not provide
enough water to wet the filters. To rectify, remove the
water restrictor from the pump supply hose adjacent
to the bleed off tee piece. See diagram.
