09 I Pool Heat Pump
Water Piping
The supplied plumbing layout must be followed without exception:
1. pool pump
2. filter
3. pool heat pump
4. chlorinator (when installed).
Rigid PVC piping is recommended with all joints primed and glued with a suitable PVC
adhesive cement. If rigid PVC pipe is not available,a suitable flexible hose of adequate
diameter may be utilised with stainless steel clamps. When the piping installation is
complete, operate the pool pump and check the system for leaks. Then check the filter
pressure gauge to see that excessive pump head pressure is not indicated.
Water Flow Rate
The recommended water flow rate range varies depending on the size of the heat pump
to ensure maximum heat transfer efficiency. The optimal flow rate is the mid point of
this range. Use the bypass valve to adjust the flow rate to within the recommended
range. See Performance Specifications table page 13.
Water By-pass Kit
A bypass kit consisting of 3 X two way valves must be installed for adjustment of
water flow and ease of service. Waterco offer prefabricated water bypass kits to fit
their heat pump domestic range. Ask your local Waterco sales office for details.
