DUAL PRESSURE SWITCH

INSPECTION
1) Check dual pressure switch (1) on liquid pipe for continuity at
normal temperature (approx. 25_C (77_F)) when A/C system
has a proper charge of refrigerant and when A/C system (com-
pressor) is under operation. In each of these cases, switch
should show proper continuity.
2) Using a manifold gauge set, check switch for operation at speci-
fied pressure as shown, refer to "PERFORMANCE DIAGNO-
SIS" in this section.
Switch ON : above "C" and below "D"
Switch OFF : below "A" or above "B"
"A": Approx. 200 kPa (2.0 kg/cm
"B": Approx. 3200 kPa (32 kg/cm
D
"C": Approx. 230 kPa (2.3 kg/cm
"D": Approx. 2800 kPa (28 kg/cm
