  1. Attach an air Conditioning Service Station.

  1. Open high pressure valve to charge the system to about 100 kpa (14psi), then close the supply valve.

  1. Check the system for leaks using a leak detector.

  1. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.), release any charge in the system according to the Discharge Procedure on page HA-59.

  1. After checking and repairing leaks, the system must be evacuated (see System Evacuation on page HA-27).


The leak detector is a delicate device that can detect small amounts of halogen.

In order to use the device properly, read the manuals supplied by the manufacturer to perform the specified maintenance and inspections.

If a gas leak is detected, proceed as follows:

  1. Check the torque on the connection fitting and, if necessary tighten to the proper torque. Check for leakage with the leak detector.

  1. If leakage continues even after the fitting has been retightened, discharge the refrigerant from the system, disconnect the fittings, and check the seat for damage. Replace fitting, even if the damage is slight.

  1. Check compressor oil and add oil if required.

  1. Charge the system and recheck for leaks. If no leaks are found, evacuate and charge the system.
