R-1234YF Charging Procedure - EMEA
Review the safety precautions and warnings in this information before performing this procedure. Failure to follow these instructions may result in serious or fatal injury.
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. See the equipment manufacturer instructions for more information.
- Start the charging procedure of refrigerant according to the instructions given in the manual to operate the equipment.NOTE:
In case of damage to the compressor or other system components, or after prolonged exposure of an open system to the air (over 6 hours) you must perform the SYSTEM WASHING procedure as follows. Using filtered compressed air to avoid introducing foreign objects into the system, clean all system components that connect to the compressor, including the compressor.
- Connect an R-1234yf refrigerant recovery/recycling/charging station that meets SAE standard J2843 to the refrigerant system.
- Charge the A/C system with the specified amount of refrigerant using the High pressure port.
- Recover the refrigerant from the Low pressure port using the recovery procedure.NOTE:
A/C system refrigerant capacity can be found on the HVAC Specification Label, located in the engine compartment.
- Repeat the charging procedure with the specified amount of R-1234yf refrigerant.NOTE:
In the case of SYSTEM WASHING, this procedure eliminated all oil in the system.
- When required, adjust the refrigerant oil level with the required amount. Refer to OIL, REFRIGERANT, STANDARD PROCEDURE .
- Disconnect the refrigerant recovery/recycling/charging station from the refrigerant system service ports.
- Reinstall the caps onto the refrigerant system service ports.
