- Find the refrigerant ports on the outside unit. There shall be two ports, one for the high-pressure facet and one for the low-pressure facet.
- Join the refrigerant charging hose to the low-pressure port.
- Connect the vacuum pump to the opposite finish of the refrigerant charging hose.
- Activate the vacuum pump and evacuate the refrigerant from the system.
- After the system has been evacuated, shut the vacuum pump.
- Open the refrigerant tank and join it to the refrigerant charging hose.
- Slowly open the valve on the refrigerant tank to cost the system with refrigerant.
- Monitor the refrigerant gauge set to make sure that the system is being charged to the proper stage.
- As soon as the system has been charged to the proper stage, shut the valve on the refrigerant tank.
- Disconnect the refrigerant charging hose and vacuum pump.
- Activate the AC unit and examine for any leaks.
How To Recharge A Window Ac Unit
