ON±VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
2. SET ON MANIFOLD GAUGE SET (See page AC±19)
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes.
Then check that the high pressure reading is 1.37 ± 1.57 MPa (14 ± 16 kgf/cm
2, 199 ± 228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT:
When the low pressure drops to 0 kPa (0 kgf/cm
2, 0 psi), check the receiver's IN and OUT sides is no temper-
ature difference.
