INTRODUCTION
10. Determine the amount of lubricant removed from the air conditioning system during the refrigerant extraction
process. Replenish the air conditioning system with an equal volume of new, correct lubricant.
11. The system is now ready for service or repair.
Flushing
Do not flush this system. In the event of a major compressor failure, replace the compressor output pressure line and
receiver/drier to collect most of the debris.
DANGER
Avoid injury!
Observe ALL precautions listed below when servicing the air-conditioning system and handling re-
frigerant.
Failure to comply will result in death or serious injury.
D0043A
Flushing should never be done with compressed air. Certain mixtures of air and R-134a are combustible. Using
compressed air to flush R-134a systems could result in fire or explosion. Air from a shop compressor also contains
moisture that would contaminate the system.
NOTICE:
Never use CFC11, R11, CFC12, R12, CFC113, R13 or any other substance to flush an R134a system. To
do so would break down the lubricant and cause system corrosion.
Use of other flushing solvents may cause other problems. If a vacuum pump does not remove the solvent, it could
affect the chemical stability of the refrigerant and lubricant.
