Figure 1. Heat Exchanger Dimensions A. Water Connections A typical piping arrangement for the installed heat exchanger is shown in Figure 2. The heat exchanger is installed downstream of the filter and upstream of the water conditioning system. The heat exchanger shall be no more than 10 feet from the heat pump compressor unit. In addition, the heat exchanger water inlet and outlet connections shall have union connections to the water circuit. - Page 5 Figure 2. Typical Pool Installation Piping The heat exchanger water connections are nominal 2 inch PVC. Plumb these connections first, as follows: 1. With abrasive cloth (Oatey #31411 or equivalent), roughen the ID surfaces of the female connectors on the heat exchanger and the OD surfaces on the water supply and return PVC pipes.
