INSTALLATION
NOTE: Typical A/C service port shown.
1. Lubricate the valve core (3) with clean refrigerant oil prior to installation. Use only refrigerant oil of the type recommended for the A/C
compressor in the vehicle.
2. Remove the tape or plug from the service port (2).
CAUTION: A valve core that is not fully seated in the A/C service port can result in damage to the valve during refrigerant system evacuation
and charge. Such damage may result in a loss of system refrigerant while uncoupling the charge adapters.
3. Using a Schrader-type valve core tool, install and tighten the valve core into the service port(s).
CAUTION: Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C system. Failure to follow this
caution will result in serious A/C compressor damage.
4. Evacuate and charge the refrigerant system See: Service and Repair/Refrigerant System Charge.
NOTE: The protective cap helps aid in service port sealing and helps protect the refrigerant system from contamination. Remember to always
reinstall the protective cap onto the service port when refrigerant system service is complete.
5. Install the protective cap (1) onto the service port.
