INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and Repair/Refrigerant Oil
Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C
compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant systemSee: Service and Repair/Refrigerant Oil Level.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the
rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
