- Add the correct type and amount of refrigerant oil to the system as specified by the vehicle manufacturer.
- Evacuate the A/C system to remove air and moisture.
- Recharge the system with the correct type and amount of refrigerant.
- Reconnect the battery and test the A/C system for proper operation and leaks.
Note: Refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
4. Operating Instructions
Once installed and the A/C system is properly charged, the compressor operates automatically as part of your vehicle's climate control system.
- To activate the air conditioning, select the A/C function on your vehicle's climate control panel.
- Adjust the temperature and fan speed settings to your desired comfort level.
- The compressor will cycle on and off as needed to maintain the set temperature.
