Installation and User’s Guide
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. Heated water
flows through the outlet, located on the left side of the heat pump.
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.
Automatic Flow Control Valve
The inlet/outlet header of the 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 100 gpm
(380 lpm). If the filter system flow rate is higher than 100 gpm (380 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 100 gpm
(380 lpm), you will have to add an external bypass valve. Excess water flow will damage the heat
exchanger.
