Follow these precautions to prevent personal
injury while operating or maintaining this
equipment.
• Legs or casters must be installed and the legs/
casters must be screwed in completely. When
casters are installed the mass of this unit will allow
it to move uncontrolled on an inclined surface.
These units must be tethered/secured to comply
with all applicable codes. Swivel casters must be
mounted on the front and rigid casters must be
mounted on the rear. Lock the front casters after
installation is complete.
• Some 50 Hz models may contain up to 150 grams
of R290 (propane) refrigerant. R290 (propane)
is flammable in concentrations of air between
approximately 2.1% and 9.5% by volume (LEL lower
explosion limit and UEL upper explosion limit). An
ignition source at a temperature higher than 470°C
is needed for a combustion to occur.
• Refer to nameplate to identify the type of
refrigerant in your equipment.
• Only trained and qualified personnel aware of the
dangers are allowed to work on the equipment.
• Read this manual thoroughly before operating,
installing or performing maintenance on the
equipment. Failure to follow instructions in this
manual can cause property damage, injury or
death.
• Crush/Pinch Hazard. Keep hands clear of moving
components. Components can move without
warning unless power is disconnected and all
potential energy is removed.
• Moisture collecting on the floor will create a
slippery surface. Clean up any water on the floor
immediately to prevent a slip hazard.
