RIGGING
The complete standard unit is shipped without skids.
(When optional skids are used, it may be necessary to
remove the skids so riggers skates can be used under
the unit end sheets to reduce the overall height.)
Each unit has four lifting holes (two on each end) in
the end sheets which should be used to lift the unit.
Care should be taken at all times during rigging and
handling to avoid damage to the unit and its external
connections. Lift only using holes shown in Figure 1
on page 11 .
Do not lift the unit with slings around
motor/compressor assembly or by means
of eyebolts in the tapped holes of the
compressor motor assembly. Do not turn
a unit on its side for rigging. Do not rig
with driveline in a vertical orientation.
If necessary to rig a unit by one end to
permit lifting or dropping through a verti-
cal passageway, such as an elevator shaft,
contact YORK Factory for special rigging
instructions.
