HVAC SYSTEM (HEATER, VENTILATOR AND A/C)

5. Refrigerant Leak Check                              CAUTION:
                                                       Carefully check the external surface of hoses
A: INSPECTION                                          and tubes at approx. 25 mm (0.98 in) per sec-
1) Operate the A/C system for approx. 10 minutes,      ond.
and confirm that the high-pressure side shows at
least 690 kPa (7.03 kg/cm2, 100 psi). Then stop the
engine to start the leak test.                                        (A)
2) Starting from the connection between the high-
pressure pipe and evaporator, check the system for
leaks along the high-pressure side through the
compressor. The following items must be checked
thoroughly.
3) Check the joint and seam between the pressure
switch (triple pressure switch) and high-pressure
pipe.                                                                                             AC-00036
4) Check the connections between the condenser
and pipes, and welded joints on the condenser.                (A) Flexible hose
The leak tester may detect the oil on the condenser
fins as a leak.                                        10) Disconnect the drain hose from the heater

8) Starting from the connection between the low-
pressure pipe and evaporator, check the system for
leakage along the low-pressure side through the
compressor. The following items must be checked
thoroughly.
