Refrigerant: Service and Repair
Evacuating the A/C System
1. Connect refrigerant recovery and recycling station to high and low side service ports. Pull vacuum on system and evacuate for 20-30 minutes.
Note vacuum gauge reading.
2. Close high and low side service valves.
3. Watch low side gauge for vacuum loss (one to three minutes). If loss is less than 3.38 kPa (1 in. Hg) from level recorded in Step 1, proceed to
charging the A/C system.
4. If vacuum loss is greater than 3.38 kPa (1 in. Hg) from level recorded in Step 1, charge with 0.23 kg (1/2 lb.) R-134a. Leak test, repair leaks, and
re-test.
IMPORTANT: Disconnect high side service valve from service port and check for vacuum loss before leak testing.
