3.2.5.2 Verication
1. Connect the SMT to the compressor.
2. Verify that the suction and discharge pressures are to specification. Refer to the “Temperature/
Pressure Sensor Verification” section of this manual for the appropriate values.
3. Verify that the temperature values are as expected. Refer to Figure 31 (Pressure/Temperature
Sensor R/T Curve) below for both the Suction and Discharge sensors.
4. If either sensor is found to be out of specification, refer to the "High and Low Pressure
Temperature Sensors" section of this manual regarding the replacement steps.
