3.7 RIGGING AND HANDING

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.
CAUTION
Before lifting, make sure the unit weight is distributed equally
on the rigging cables so it will lift evenly.
Units may be moved or lifted with a forklift. Slotted openings in the
base rails are provided for this purpose.
CAUTION
All panels must be secured in place when the unit is lifted.
The condenser coils should be protected from rigging cable
damage with plywood or other suitable material.
Both ends must be
open for downflow or
sideflow ductwork to
provide ventilation
