Refrigerant Handling Safety
Refrigerant Recovery
Some refrigeration system refrigerant compounds
are chlorofluorocarbons, and therefore may be
damaging to the earth’s ozone layer.
Consequently, the release of refrigerant into the
atmosphere must be avoided. Whenever
refrigerant is to be removed from the refrigeration
system, a refrigerant recovery unit must be used to
recover the refrigerant. This refrigerant can then
be recycled and reused, which is both
environmentally safe and economical.
NOTE: Consult the operators manual for your
recovery unit for the proper hookup and
operating procedures.

Compressor Function Test
Preliminary Checks
1. Check the suction and discharge pressures to
make sure they are in an acceptable range.
2. Check to make sure the unit is cooling.
3. Check the compressor for signs of overheating
such as discolored stickers on the compressor
body.
4. Check to make sure the compressor clutch has
12 volt power when energized.
DANGER: Explosion Hazard! Never
throw or strike refrigerant bottles and
never handle the packing carton roughly.
Do not use refrigerant bottles that are
damaged or dented. Store refrigerant
bottles out of reach of children.
DANGER: Explosion Hazard! Never
directly heat refrigerant bottles or put
them in hot water heated above 104 F (40
C) because the bottle might explode and
cause personal injury. When it is
necessary to heat refrigerant bottles for
charging in cold weather, use warm water
at a temperature below 104 F (40 C).
DANGER: Explosion Hazard! Never put
refrigerant bottles on the engine or the
radiator when charging Excessive heat
increases pressure to a dangerous level
that might cause the bottle to explode.
DANGER: Explosion Hazard! Never store
refrigerant bottles in direct sunlight, near
flame, or where the temperature exceeds
104 F (40 C). Always store refrigerant
bottles in a cool dry place.
CAUTION: Do not put the charge valve in
warm water.
