Pool Heat Pump _15
PLUMBING SPECIFICATIONS
Factory connections are for a 1 1/2" union nut.
Join the Pool Heat Pump inlet and outlet with rigid PVC (schedule 40). All joints must be glued with PVC glue. If rigid pipe
is not available, you can use soft or flexible piping with stainless steel clamps.
When the piping installation is completed, start the pool pump and check the system for leaks.
Check valve & Chemical trap loop
Ensure that the check valve and chemical trap loop are installed as shown above. The loop should be at least 8 inches
above the top of the chlorinator/feeder to prevent chlorine backup into the heater when the water pump is off. Install a
check-valve on the heater side of the loop to to prevent chlorine damage.
Flow rate
The
DPL
Pool Heat Pump is designed to handle the full flow from the pool pump. No bypass is required if the flow is in the
30 to 70 gallon per minute range.
Warning:
Flow rates exceeding 70 GPM may damage the unit and compromise its efficiency.
External Bypass
Good practice also suggests considering the use of an external bypass on the inlet and outlet to enable the pool owner
to bypass the pool heater if service or maintenance is required.
