Use care to prevent refrigerant from touching your skin or eyes. Liquid refrigerant, when exposed to air,
quickly evaporates and will freeze skin or eye tissue. Serious injury or blindness may result if you come
in contact with liquid refrigerant.
Refrigerant R-134a air conditioning systems should not be pressure tested or leak tested with com-
pressed air. Combustible mixtures of air and R-134a may form, resulting in a fire or explosion, which
could cause personnel injury or death.
Always use correct refrigerant oil in R-134a air conditioning system. Never mix oils. If wrong oil is
used, or if oils are mixed, compressor could seize due to improper lubrication.
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.
Replacing only the amount of refrigerant oil that was removed during evacuation may result in wrong oil
charge; oil charge may have been incorrect prior to evacuation. The only way to ensure proper oil charge is
to check oil level in compressor with an oil level gage.
When handling refrigerant oil:
Oil should be free of water, dust, metal powder, and other foreign substances.
DO NOT mix refrigerant oil with other types or viscosities of oil.
Quickly seal oil container after use. Refrigerant oil absorbs moisture when exposed to air for any period of time.
