Note: In order to properly use the electronic leak detector, it is recommended to read its instructions.
1. Check the tightening torque of the pipe connections. When loosening, tighten the connections to the specified torque. With a leak detector (A) make sure there are no gas leaks.
2. If the leak persists after tightening the joint, discharge the system, disconnect the joint and check the sealing surfaces for damage. Even slightly damaged connection parts must be replaced.
3. Check the amount of compressor oil and top up if necessary.
4. Charge the system and check for leaks. If no leaks are found, vacuum purge and charge the system.
