Figure 2. Suction Pressure Transducer.
NOTE
Before installing the replacement suction pressure transducer, it must be calibrated.
Calibration of the suction pressure transducer cannot be accomplished if the run
relay is energized. The following steps will allow you to calibrate the transducer while
the run relay is de-energized.
Calibration of the transducer must be accomplished at atmospheric pressure (0.0
psig or 14.7 psia). If the sensor reading is greater than 20 psig (34.7 psia) or less
than -6.7 psig (8 psia), the transducer cannot be calibrated.

Item 5) closed and lower cover.
