Charging Valve Core

NOTE: A possible reason for leakage of refrigerant from the system may be a damaged or bent schraeder valve. To check that the valve core is the cause of leakage, use a soap solution. If the valve core is leaking replace it.

- Depressurize the system.
- Using a schraeder valve removing tool remove the valve core.
- Install a new core.

NOTE: Do not overtighten.

- Evacuate and recharge the system.
