Installation Procedure
1. Disconnect electrical power at the main breaker.
2. Drain the system (if applicable).
3. Install the pressure sensor and pressure shut-off sensor at the
pressure tank tee downstream of the pressure tank (the pressure
tank should be between the pressure sensor and the pump). The
sensors have a ΒΌ-18 National Pipe Thread (NPT) connection.
The pressure sensors should not be installed in an inverted
orientation (up-side down). Make sure the pressure sensor and tank
are not located more than 3 feet off the main piping.
4. Install the unit to the wall using four mounting screws (not included) as
shown in Figure 1 below. Remove the SubDrive lid by removing the eight
lid screws.
