Hose/Line HVAC: Service and Repair

COMPRESSOR MANIFOLD AND TUBE ASSEMBLY







Removal and Installation

CAUTION: Do not stress or bend the aluminum lines on the compressor manifold and tube assembly to facilitate removal. Bending or squeezing the lines together may damage the welds and lead to premature failure of the line.

NOTE: Installation of a new receiver/drier cartridge is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the receiver/drier cartridge.
