NOTE: In different models, the throttle assembly may be Capillary or Electronic expansion valve.
4-4. Air Purging and Leakage Test
1. Connect charging hose of manifold valve to charge end of low pressure valve (both high/low
pressure valves must be tightly shut).
2. Connect joint of charging hose to vacuum pump.
3. Fully open the handle of Lo manifold valve.
4. Open the vacuum pump to evacuate. At the beginning, slightly loosen joint nut of low pressure
valve to check if there is air coming inside. (If noise of vacuum pump has been changed, the
reading of multimeter is 0) Then tighten the nut.
5. Keep evacuating for more than 15mins and make sure the reading of multi-meter is -1.0 X105
pa (-76cmHg).
