[7] ELECTRICAL SYSTEM
(1) Electrical Circuit
The process of magnetic clutch being engaged is shown below.
Main Switch (3) ON → A/C Switch (15) ON → Blower Switch (12) ON (Low, Medium 1, Medium 2 or High) →
Compressor Relay (7) ON → Thermo Amplifier (4) ON (the thermostat temperature is more than 3 °C (37.4 °F)) →
Pressure Switch (6) ON (if refrigerant pressure is between 0.21 MPa (2.1 kgf/cm
2
, 30 psi) and 2.65 MPa (27 kgf/cm
2
,
384 psi) → Magnetic Clutch of Compressor Engaged.
