Bleed-off
All evaporative air conditioners need some water bleed-off to prevent build-up of mineral deposits in
the system. The correct setting of the bleed rate will ultimately govern the life of the unit.
With normal town water supply, bleed rate should be adjusted so that the discharge is not less than
approximately 10 litres per hour. Increased water hardness may require a higher bleed rate and
increased maintenance.
The method for setting the bleed rate is to adjust the patented DIALFLO unit located externally on the
unit.
It is recommended to plumb the bleed-off away from the unit to a down pipe in situations where the
discharge may cause unsightly stains, e.g. Colorbond Roofs.
If dump valve fitted and dumping cycles activated, bleed off may not be required.
Dump Valve (Where Fitted)
A dump valve can be fitted to a unit using the MANUAL control. There are no timer control functions
available with this control. The dump valve solenoid is activated or deactivated when the pump
operation is used.
