Flow switch, relief valve and temperature and pressure gauge installation

Basic steps are listed below to guide you through the installation of the flow switch, relief valve, and temperature and pressure gauge provided with the unit.

1.For Models 399 - 500 install the close nipple on the outlet connection of the heat exchanger. Install the tee with the 3/4 inch fitting positioned vertically and on the top as shown in FIG. 6-1. For Models 600 - 800 install the tee directly to the outlet connection of the heat exchanger with the 3/4 inch fitting positioned vertically and on the top (see FIG. 6-2).

2.For Models 700 - 800 install the 3/4 inch close nipple in the tee. Install the relief valve on the 3/4 inch close nipple (FIG. 6-2). For Models 399 - 600 install the relief valve directly into the 3/4 inch fitting on the tee (FIG. 6-1).

3.Install the close nipple on the downstream side of the relief valve tee (FIG. 6-1).

4.Install the tee with the 1 inch fitting positioned vertically and on the top (FIG. 6-1).
