A/C System Charging Procedure
Adding Refrigerant
NOTE: The system should be charged with refrigerant only after following A/C System Evacuation and Leak Check
Procedures on page 36.
NOTE: Refrigerant charge is sensitive. Use smallest practical refrigerant bottle with accurate and reliable scale.
IMPORTANT: Keep all the A/C fittings capped and sealed until the installation of the refrigeration hoses.
Refrigerant oil is extremely hygroscopic and a system left open for more than 5 minutes may require extensive
evacuation time to remove moisture.
Special Tools Required
R-134a Refrigerant
Accurate Scale
1. Connect the refrigerant bottle to the gauge manifold and place it on a scale.
2. Open the refrigerant bottle valve for liquid and purge the charging line.
3. Keep the low pressure side valve of the gauge manifold closed. Open the high pressure side valve.
4. Slowly add refrigerant until reaching 2 lbs. of R-134a. NOTE: The system never uses more than 2 lbs. of
refrigerant. Accuracy is important. Over or under charging by 3 oz will reduce cooling capacity and reduce
maximum system run time.
5. Close the refrigerant bottle valve and the high side valve of the gauge manifold.
6. Remove the gauge manifold.
7. Reinstall only the access cover over the evaporator coil.
