Water Connections at the Heat Pump

Two inch Quick Connect fittings have been installed on the water inlet and outlet connections, see Figure 7. Filtered cool water is plumbed to the inlet, located on the right side of the heat pump front panel. Heated water flows through the outlet, located on the left side of the heat pump front.

Plastic piping (PVC Schedule 40) should be connected to the heat pump. The unions, provided with the unit, accept 2 in. PVC pipe.

CAUTION — Make sure that flow requirements and pool water turnover rates can be maintained with the installation of additional heat pumps and plumbing restrictions.

Check Valve Installation

The heat pump must be protected from back-siphoning of water. If there is any chance of back-siphoning, provide a check valve between the pool and the heat pump outlet.

CAUTION — The chlorinator placement, water balance, and where chemicals are added, are very important aspects of the installation. Failure to protect the heat pump unit from chemical damage is not covered under the warranty.

When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat pump. A check valve must be installed between the heat pump and the chemical feeder to prevent back-siphoning of chemically saturated water into the heat pump where it will damage the components.

Automatic Flow Control Valve

The inlet/outlet header of the ThermalFlo HP heat pump comes equipped with an internal automatic flow control valve. The automatic flow control valve maintains the proper flow through the heat pump at rates up to 125 gpm (475 lpm). If the filter system flow rate is higher than 125 gpm (475 lpm), install a manual bypass valve, see Figure 6 on page 7.

NOTE: Be advised that if your circulation pump is over 2 HP or if the total flow exceeds 125 gpm, you will have to add an external bypass valve. Excess water flow will damage the heat exchanger.
