REFRIGERANT TEMPERATURE SWITCH
CAUTION
Do not heat more than necessary.
1. Dip the metal part of the cooling 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.
Standard value:
NOTE: When the oil temperature is 150
°C or
more and there is no continuity, the resistance will
not be 2
Ω or lower until the oil temperature
reduces to 120
°C or less.
