and proper unit operation.
RIGGING AND HANDLING
Exercise care when moving the unit. Do not remove any packaging until
the unit is near the place of installation. Rig the unit by attaching chain
or cable slings to the lifting holes provided in the base rails. Spreader
bars, whose length exceeds the largest dimension across the unit,
MUST
be used across the top of the unit.
Units may be moved or lifted with a forklift. Slotted openings in the base
rails are provided for this purpose.

CAUTION
Before lifting, make sure the unit weight is distributed equally on the
rigging cables so it will lift evenly.

roof curb, gasket or sealant must be applied to all surfaces that come
in contact with the unit underside.
CAUTION
All panels must be secured in place when the unit is lifted.
The outdoor coils should be protected from rigging cable damage
with plywood or other suitable material.
