L CAUTION %

Avoid breathing refrigerant or lubricant vapor or mist.

Exposure may irritate eyes, nose and throat.

If accidental system discharge occurs, ventilate work area before resuming

service.

Additional health and safety information may be obtained from refrigerant and

lubricant manufacturers.

Special Considerations with R134a

R134a has been shown to be nonflammable at ambient temperature and

atmospheric pressure. However, tests under controlled conditions have indicated

that, at pressures above atmospheric and with air concentrations greater than 60%

by volume, R134a can form combustible mixtures.

While it is recognized that an ignition source is also required for combustion to

occur, the presence of combustible mixtures is a potentially dangerous situation

and should be avoided.

Under no circumstances should any equipment be pressure tested or leak tested

with Air/R134a mixtures. Do not use compressed air (shop air) for leak detection

in R134a systems.
