Refrigerant System - Charge
REFRIGERANT SYSTEM CHARGE
WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation See: Heating and Air
Conditioning/Service Precautions/Warning and See: Heating and Air Conditioning/Service Precautions/Caution . Failure to follow these
instructions may result in serious or fatal injury.
NOTE: The Underhood HVAC Specification Label contains the refrigerant fill specification of the vehicle being serviced.
After all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerant charge can be injected into the system
When servicing the A/C system, use an R-134a refrigerant recovery/recycling/charging station (1) that meets SAE standard J2788. Per SAE standard
J2788, refrigerant recovery stations must charge the system to an accuracy of 14 grams (0.5 oz.). See the operating instructions supplied by the
equipment manufacturer for proper care and use of this equipment.
CHARGING PROCEDURE
CAUTION: A small amount of refrigerant oil is removed from the A/C system each time the refrigerant system is recovered and evacuated.
Before charging the A/C system, you MUST replenish any oil lost during the recovery process. Refer the equipment manufacturer
instructions for more information.
1. Evacuate the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Evacuate.
2. Connect an R-134a refrigerant recovery/recycling/charging station that meets SAE standard J2788 to the refrigerant system.
3. Measure the proper amount of refrigerant and heat it to 52° C (125° F) with the charging station See: Heating and Air
Conditioning/Specifications/Capacity Specifications/Refrigerant Charge Capacity. See the operating instructions supplied by the equipment
manufacturer for proper use of this equipment.
4. Open both the suction and discharge valves, then open the charge valve to allow the heated refrigerant to flow into the system.
5. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
6. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heating-A/C system
controls so that the A/C compressor is engaged and the blower motor is operating at its lowest speed setting. Run the engine at a steady high idle
(about 1400 rpm). If the A/C compressor does not engage, test the compressor clutch circuits and repair as required.
WARNING: Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning may result in serious or fatal
injury.
7. Open the low-side valve to allow the remaining refrigerant to transfer to the refrigerant system.
8. Disconnect the charging station from the refrigerant system service ports.
9. Reinstall the caps onto the refrigerant system service ports.
