SPECIFIC WARNING AND CAUTION STATEMENTS
To help identify the label hazards on the Unit and explain the level of awareness each one carries, an explanation is
given with the appropriate consequences:
DANGER -- means an immediate hazard which WILL result in severe personal injury or death.
WARNING -- means to w arn against hazards or unsafe conditions which COULD result in se ver e per sonal injury or
death.
CAUTION -- means towarn against potential hazardor unsafepractice w hich COULD result inminor personal injury,
product or property damage.
The statements listed below are applicable to the refrigeration unit and appear elsewhere in this manual. These rec-
ommendedprecautions mustbe understood andapplied during operation and maintenance of the equipment covered
herein.
WARNING
When servicing the un i t, us e caution when handling R-134a. The refrigerant when in contact with
high temperatures (about 1000_F) will decompose into highly corrosive and toxic compounds.
WARNING
Be sure to avoid refrigerant coming in contact with the eyes. Should refrigerant come in contact
with the eyes, wash eyes for a minimum of 15 minutes with potable water only. THE USE OF
MINERAL OIL OR REFRIGERANT OILS IS NOT RECOMMENDED.
WARNING
Be sure to avoid refrigerant coming in contact with the skin. Should refrigerant come in contact
with the skin, it should be treated as if the skin had been frostbitten or frozen.
WARNING
Be sur e ventilation in the workspace is adequate to keep the concentration of refrigerant below
1000 parts per million. If necessary, use portable blowers.
WARNING
Beware of rotating fan blades and unannounced starting of fans.
WARNING
Do not use a nitrogen cylinder without a pressure regulator. Never mix refrigerants with air for
leak testing. It has been determined that pressurized, air-rich mixtures of r efrigerants and air can
undergo combustion when exposed to an ignition source.
WARNING
Never fill a refrigerant cylinder beyond its rated capacity. Cylinder may ruptur e due to excessive
pressur e when exposed to high temperatures.
WARNING
When starting the unit, be sure that all manual refrigerant valves in the discharge line are open.
Severe damage could occur from extremely high refrigerant pressures.
