Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. 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 system.
NOTE: Replacement of the refrigerant line O-ring seals is required anytime the A/C expansion valve is removed. Failure to replace the rubber O-ring
seals may result in a refrigerant system leak.
