4. When the low-pressure side reading increases to
0.098 MPa {1.0 kgf/cm
2
, 14 psi},

5. Inspect for leakage from the cooler pipe/hose connections using a gas leak tester.
z
If there is no leakage, go to Step 7.
z
If leakage is found at a loose joint, tighten the joint, then go to the next step.

z
If there is no leakage after tightening the joint, go to the next step.
z
If there is still a leakage at the same joint, discharge the refrigerant and then repair the joint. Repeat
the charging procedure from evacuation.
