Description
The A/C refrigerant lines and pipes are used to carry the refrigerant between the various A/C system components.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire A/C system and can
reduce the flow of refrigerant within the system.
Operation
High pressure is produced in a refrigerant system when the A/C compressor is operating. Extreme care must be
exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good
practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and
properly routed. Depending on vehicle, model and market application, refrigerant lines are connected to each other or
other A/C system components with block-type or quick-connect type fittings. To ensure the integrity of the refrigerant
system, O-rings and/or gaskets may be used to seal the refrigerant system connections. The refrigerant lines and
hoses cannot be repaired and must be replaced if leaking or damaged.
WARNING!
The A/C system contains refrigerant under high pressure. Repairs should only be performed by qualified service
personnel. Serious or fatal injury may result from improper service procedures.
If accidental A/C system discharge occurs, ventilate the work area before resuming service. Large amounts of
refrigerant released in a closed work area will displace the oxygen and cause suffocation and serious or fatal
injury.
CAUTION:
Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on an R-134a A/C system. These refrigerants are not compatible and damage to the A/C sys-
tem will result.
CAUTION:
Never use R-12 refrigerant oil in an A/C system designed to use R-134a refrigerant oil. These refrig-
erant oils are not compatible and damage to the A/C system will result.
CAUTION:
Do not run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
CAUTION:
Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.
