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.
WARNING
Do not attach supply and return duct work to the bottom of the unit
base pan as the drain pan could be compromised.

may result in equipment damage or personal injury. Typical contami-
nates include: permanent wave solution, chlorinated waxes and
cleaners, chlorine based swimming pool chemicals, water softening
chemicals, carbon tetrachloride, Halogen type refrigerants, cleaning
solvents (e.g. perchloroethylene), printing inks, paint removers, var-

in contact with the unit underside.
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.
