Expansion Valve: Testing and Inspection
1. CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
2. SET ON MANIFOLD GAUGE SET
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 kg/sq.cm, 199 - 228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will drop to 0 kPa (0 kg/sq.cm, 0 psi).
HINT: When the low pressure drops to 0 kPa (0 kg/sq.cm, 0 psi), check the receiver's IN and OUT sides is no temperature difference.
