DUAL PRESSURE SWITCH
INSPECTION
1) Check dual pressure switch (1) on liquid pipe for continuity at
normal temperature (approx. 25C (77F)) 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 ªPERFORMANCE DIAGNO-
SISº in this section.
Switch ON : above ªCº and below ªDº
Switch OFF : below ªAº or above ªBº
ªAº: Approx. 200 kPa (2.0 kg / cm
2)
ªBº: Approx. 3200 kPa (32 kg / cm
