Pool Heat Pump
Protection devices
The integrity and performance of your pool heat pump and its components are protected
by internal safety controls. In normal use, your Waterco unit should never reach the thermal
protection level. However, if it should happen, you should identify the stated code on the
temparature display and refer to Service Analyser codes.
Adjustment Of The Bypass Valves
The adjustment may vary according to pool pump size and ambient temperatures.
ATTENTION: IT IS VERY IMPORTANT THAT THE BYPASS VALVES ARE SET AS DESCRIBED
BELOW FOR THE CORRECT FUNCTION OF YOUR POOL HEAT PUMP
