Figure 3. Pressure Sensor Dimensions
Install Pressure Sensors
Two pressure sensors are mounted on the pump manifolds, one on the discharge
and one on the intake. If there is a check valve in the discharge side of the pump,
mount the discharge sensor before the check valve. T-ttings can be used to mount
the pressure sensors.
Note: Install the pressure sensor upright so that water in the end of the pressure
sensor is able to drain back into the pipe.
1. Screw the sensor into a 1/4-18 NPT hole.
Caution: Do not use the main body that houses the electronics to tighten the
pressure sensor. Damage to the sensor may occur.
2. Tighten the sensor with a 7/8 inch wrench on the lower hex tting.
3. Connect the pressure sensor cable from the control module to the pressure
sensor. (Refer to Wiring Section.)
Caution: Do not use the main
body that houses the electronics
to tighten the sensor. Damage to
the sensor may occur.
Caution: The discharge and intake
pressure sensors are the same size.
Ensure the correct sensor is installed on
the correct manifold. Refer to Table 1.
