REFRIGERANT TEMPERATURE SWITCH
CAUTION: Do not heat more than necessary.
1. Dip the metal part of the refrigerant temperature switch into engine oil and increase the oil temperature using a gas burner or similar.
2. When the oil temperature reaches the standard value, check that voltage is supplied between the terminals.
NOTE: When the oil temperature is 150 °C (302 °F) or more and there is no continuity, the resistance will not be 2 ohm or lower until the oil temperature reduces to 120 °C (248 °F) or less.
