Checking Refrigerant Leaks

CHECKING REFRIGERANT LEAKS





Conduct a leak test with an electronic leak detector whenever leakage of refrigerant is suspected and when conducting service operations that are accompanied by disassembly or loosening of connection fittings

NOTE: In order to use the device properly, read the information 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 too loose, tighten to the proper torque. Check for gas leakage with a leak detector.
2. If leakage continues even after the fitting has been tightened, discharge the refrigerant from the system, disconnect the fittings, and check its seating face for damage. Always replace, even if the damage is slight.
3. Check compressor oil and add oil if required.
4. Utilize a partial charge the system to recheck for gas leaks. If no leaks are found, evacuate and charge the system.
