Inspect For Leakage Of Refrigerant

(b) Secure good ventilation (The gas leak detector may not react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust gas)

(c) Repeat the test 2 or 3 times

(d) Make sure that there is some refrigerant remaining in the refrigeration system.

When compressor is OFF: approx. 392 - 588 kPa (4 - 6 kgfcm2, 57 - 85 psi)

(e) Bring the gas leak detector close to the drain hose before performing the test.

HINT:

♦ After the blower motor stops, leave the cooling for more than 15 minutes.

♦ Expose the gas leak detector sensor under the drain hose.

♦ When bring the gas leak detector close to the drain hose, make sure that the gas leak detector does not react to the volatile gases.

If gas leaks are detected, lift up the vehicle.

(f) If gas leaks are not detected on the drain hose, remove the blower resistor from the cooling unit. Then insert the gas leak detector sensor into the unit to perform the test.

(g) Disconnect the connector and leave the pressure switch for approx. 20 minutes. Then bring the gas leak detector close to the pressure switch to perform the test.

(h) Bring the gas leak detector close to the refrigerant lines.
