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
because 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.
Safety Precautions
WARNING: Always wear 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 and belts 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.
WARNING: Never drill holes in the unit unless absolutely necessary.
Holes drilled into the unit may weaken structural components. Holes
drilled into electrical wiring can cause fire or explosion.
WARNING: When using ladders to install or service refrigeration
systems, always observe the ladder manufacturer's safety labels and
warnings. A work platform is the recommended method for
installations.
WARNING: Exposed coil fins are very sharp and can cause painful
lacerations.
