Vehicle: 2003 Subaru Baja 2.5 H4 GAS
Using Vacuum Pump
Vacuum pumps suitable for removing air and moisture from A/C systems are commercially available. A specification for system pump down used here is 28-291/2 inches vacuum. This reading can be attained at or near sea level only. For each 1000 feet of altitude this operation is performed, the reading will be 1 inch vacuum higher. For example, at 5000 feet elevation, only 23-241/2 inches of vacuum can be obtained. The system refrigerant must be completely recovered before it can be evacuated. Damage to the vacuum pump will result if pressurized ...
