Water piping ? IMPORTANT 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 ! CAUTION The wiring of your pool heat pump should be performed by a qualified electrician in accordance with local requirements. A properly-sized breaker and copper wire must be used. Check the heat pump data label for required maximum breaker size. WARNING The unit must always be powered off before opening the access panel. OWNER'S MANUAL 7
