III. Water Connections
The heat pump inlet and outlet connections are NOT interchangeable.
They must be connected as instructed below.
1. Connect the heat pump in the return water line between the filter and the pool. See page 10,
Plumbing Diagrams.
2. Connect the filter outlet to the fitting marked
WATER IN at the bottom side of the unit. Unit
inlet/outlet connection fittings are 2-inch PVC unions.
3. Connect the fitting marked
WATER OUT to the return piping to the pool.
Water connections from the heat pump to the main return line can be PVC pipe or flexible pipe
approved for the purpose and, in either case, must be at least equal in size to the main pool
circulation piping.
4. Operate the pump and check the unit for water leaks.
Install a check valve and/or a Hartford loop AFTER the heat pump and
BEFORE any chlorinating devices. Install any automatic chemical feeders
AFTER the heat pump. Improper installation of erosion-type automatic
chemical feeders can result in serious damage to, or premature failure of,
the heat pump and will void the heat pump warranty.
IV. Controls and Indicator Lamps
Your heat pump incorporates safety controls and indicators to ensure its safe, reliable operation.
Water Pressure Switch: Prevents operation when the pump is OFF. The unit requires 5 psi
minimum pressure.
Water Temperature Control: Pool water temperature is controlled by the heat pump thermostat
on the unit control panel, which contains a switch and 2 thermostats, one for setting a heat spa
temperature and the other for a swimming pool temperature. The switch can operate an optional
external control system, or can switch between thermostats for pool or spa.
