Water piping
The piping sequence is as follows: pool > pool pump > filter > heater > check
valve > chemical feeder > pool. Automated chlorine distribution systems, if
used, must be placed downstream of the heater to minimize harm to the pool
equipment. Use rigid PVC piping if possible (SCH40 or SCH80). All joints should
be glued with PVC glue. When the piping installation is complete, operate the
pool pump and check the system for leaks. Then, check the filter pressure
gauge to verify that there isn’t any indication of excessive pump head pressure.
You can also make the connections using high-pressure flexible hose, but
make sure the hose can withstand high pressure. The installation of a heat
pump bypass is not necessary unless the water flow exceeds 75 GPM.
Note: Certain installations have valves which isolate the heat pump from the water circuit. If the heat exchanger
is deprived of water circulation for several days, high chlorine gas could cause excessive corrosion. If the disconnect
switch is turned off, be sure that the pool water is allowed to circulate through the unit, or is drained out of it.
Electrical
The wiring of your pool heat pump should be performed by a qualified
electrician in accordance with local requirements.
Suitable electrical supply line:
See rating plate on the heat pump units for
electrical specifications. A junction box is not needed at the heat pump; con-
nections are made inside the heat pump electrical compartment. Minimum
wire size to be selected per nEC SEC.440.33 based on unit MCA.
An electrical disconnect switch that will interrupt all power to the unit is
required. This switch MUST be installed within line of sight of the heat pump.
Check the heat pump data label for required maximum breaker size.
The unit must always be powered off before opening the access panel.
