Water Piping; Electrical - Hayward Easy Temp Owner's Manual

Water piping

?
IMPORTANT
The piping sequence is as follows: pool > pool pump > fi lter > 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 fi lter
pressure gauge to verify that there isn't any indication of excessive pump
head pressure.
You can also make the connections using high-pressure fl exible hose, but
make sure the hose can withstand high pressure. The installation of a heat
pump bypass is not necessary unless the water fl ow 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.

CAUTION
The wiring of your pool heat pump should be performed by a qualifi ed
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.
