G pressure in the system rises G operating current rises G cooling (or heating) efficiency drops G moisture in the refrigerant circuit may freeze and block capillary tubing G water may lead to corrosion of parts in the refrigerant system Therefore, the indoor unit and tubing between the indoor and... - Page 68 07-007 W-2WAY_II_NA 1/23/07 6:09 PM (4) Do a leak test of all joints of the tubing (both indoor and outdoor) and both gas and liquid service valves. Bub- bles indicate a leak. Wipe off the soap with a clean cloth after a leak test.
- Page 69 07-007 W-2WAY_II_NA 1/23/07 6:09 PM NOTE The required time in the above table is calculated based on the assumption that the ideal (or target) vacuum condition is less than –14.7 psig (–755 mmHg, 5 Torr). (2) When the desired vacuum is reached, close the “Lo” knob of the manifold valve and turn off the vacuum pump.
