HEAT PUMP
Water In
Plumbing connections to
the heater must be made
by hand only as it may
break the water Inlet or
Outlet connections.
1. A 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. These units are fitted with a flow switch which are not effected by water pressure.
Therefore, the fitment of a flow check valve due to the installed height either above
or below water level is not required.
3. For units installed above the pool water level the return water to the pool valve on
the bypass valve set should be closed approximately 15-20% to ensure the heat
exchanger is completely full of water to allow heat transfer to occur.
