Once the leak is found, replace and correct the leak or part. Also, whenever the
system is opened to the atmosphere or there has been a leak in the system,
the receiver drier must be changed.
Generally the air conditioning system is very sensitive to any contaminants or
non condensable’s, such as dirt and mo isture. Extra care is required when
installing or servicing the air conditioning system to eliminate the possibility of
contaminants entering the system.
Never leave hose fittings, compressor fittings, or components uncapped .
Dirt and moisture will harm the system performance very quickly and this is the
number one cause for compressor failure. Most compressor failures never
receive warranty due to contamination in the system.
When installing, or servicing air conditioning components, only new or properly
cleaned components should be used . Before charging the system with
refrigerant, the system should be pulled into a vacuum for a minimum of 45
minutes. This will allow for any moisture in the system to be removed.
