Sharp Edges
The fins on the air-cooled condenser coils have sharp
metal edges. Reasonable care should be taken when
working in contact with the coils to avoid the risk of
minor abrasions and lacerations. The use of gloves is
recommended.
Frame rails, braces, and other components may also
have sharp edges. Reasonable care should be taken when
working in contact with any components to avoid risk
of minor abrasions and lacerations.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally
nontoxic, non-flammable and non-corrosive, and pose
no special safety hazards. However, the use of gloves
and safety glasses are recommended when working on
the unit. The build up of refrigerant vapor, from a leak
for example, does pose a risk of asphyxiation in confined
or enclosed spaces and attention should be given to good
ventilation.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods (e.g.
steam cleaning) should not be used on any part of the
pressure system as this may cause operation of the
pressure relief device(s). Detergents and solvents, which
may cause corrosion, should also be avoided.
Emergency Shutdown
In case of emergency, the non-fused disconnect switch
on the power panel should be used as the emergency stop
device. When operated it removes the electrical supply
to the unit thus shutting down the unit.
Safety Labels
The following labels are fixed to each unit to give
instruction, or to indicate potential hazards which may
