Refrigerant Recovered
General Safety Instructions:
WARNING
Do not remove air conditioner compressor oil
fill plug without first recovering the system.
Failure to recover the system could cause
uncontrolled release of
high-pressure
refrigerant, which can freeze skin and eye
tissue causing serious Injury or blindness.
GENERAL INFORMATION
CAUTION
l Always use the correct refrigerant oil in R-134a air conditioning
system. Never mix oils. If the wrong oil is used, or if oils are
mixed, the compressor could seize due to improper lubrication.
l Refrigerant oil must be from a container that has not been opened
or that has been tightly sealed since its last use. Tubing, funnels,
or other equipment used to transfer refrigerant oil should be very
clean and dry. Failure to follow this caution may result in
contamination of system.
NOTE
Replacing only the amount of refrigerant oil that was removed during evacuation may result
in the wrong oil charge; oil charge may have been incorrect prior to evacuation. The only way
to ensure proper oil charge is to check the oil level in the compressor with an oil level gage.
