INSTALLATION INSTRUCTIONS
Water Piping
The following piping sequence must be followed without exception: 1-pool pump 2-filter
3-pool heat pump 4 chlorinator (when installed). Rigid PVC piping is recommended, all
joints should be glued with PVC glue. If rigid PVC is not available, you can use soft or
flexible piping 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.
NOTE: Units are designed to operate
with a minimum water circulation of 132 LPM/35 GPM.
NOTE: A bypass kit is strongly recommended and should be installed for adjustment of
water flow and ease of service.
1. Either a 1/3 pound check valve or a loop
MUST
be installed between the pool heat
pump and any automatic chlorinator to prevent highly chlorine concentrated water from
flowing back to the pool heat pump when the pool pump is not running.
2. Units which are located below the water level of the swimming pool may require the
pressure switch to be adjusted.
This can be checked by the following method:
i) switch on the water pump and pool heat pump.
ii) while the pool heat pump is running switch “OFF” the water pump.
If the pool heat pump shuts down automatically no further action is required.
If the heat pump continues to run you will need to have a qualified technician adjust the
water pressure switch. For further information please, contact Waterco.
