Safety Precautions
The symbol appears next to a point that is particularly important:
DANGER: Addresses a circumstance that, if encountered, will
lead to death or serious injury.
WARNING: Addresses a circumstance that, if encountered, might
lead to death or serious injury.
CAUTION: Addresses a circumstance that, if encountered, may
cause damage to equipment or minor injury.
DANGER: Never operate the unit with the discharge valve closed
as it could cause the compressor to explode, causing death or
serious injury.
DANGER: Never apply heat to a sealed refrigeration system or
container because it could explode, causing death or serious
injury.
DANGER: Fluorocarbon refrigerants, in the presence of an open
flame or electrical short, produce toxic gases that are severe
respiratory irritants capable of causing death.
DANGER: Be careful when working with a refrigerant or
refrigeration system in any enclosed or confined area with a
limited air supply (i.e., a trailer, container or the hold of a ship).
Refrigerant tends to displace air and can cause oxygen depletion
which may result in death by suffocation.
WARNING: Always wear eye protection such as goggles or safety
glasses. Refrigerant liquid, refrigeration oil, and battery acid can
permanently damage the eyes (see First Aid under Refrigeration
Oil).
WARNING: Keep your hands away from fans when the unit is
running. This should also be considered when opening and
closing the compressor service valves.
WARNING: Make sure gauge manifold hoses are in good
condition. Never let them come in contact with a belt, fan motor
pulley, or any hot surface.
WARNING: Make sure all mounting bolts are tight and are of
correct length for their particular application.
