1) Check dual pressure switch (1) for continuity at normal temper-
ature (approx. 25 C (77 F)) when A/C system has a proper
charge of refrigerant and when A/C system (compressor) is un-
der operation. In each of these cases, switch should show prop-
er continuity.
2) Check switch for continuity at specified pressure as shown.
A: Approx 200 KPa (2.0 kg/cm
B: Approx 320 KPa (32 kg/cm
C: Approx 230 KPa (2.3 kg/cm
D: Approx 2800 KPa (28 kg/cm
Tightening torque for dual pressure switch
11 N·m (1.1 kg-m, 8.0 lb-ft)
