6. Maintain level tolerance to 1/2” across the entire width
and length of unit.
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.
LENGTH OF FORKS MUST BE A MINIMUM OF 60
INCHES.
Excessive exposure of this furnace to contaminated
combustion air may result in equipment damage or
personal injury. Typical contaminates include: per-
manent wave solution, chlorinated waxes and clean-
ers, chlorine based swimming pool chemicals, water
softening chemicals, carbon tetrachloride, Halogen
type refrigerants, cleaning solvents (e.g. perchloro-
ethylene), printing inks, paint removers, varnishes,
hydrochloric acid, cements and glues, antistatic fab-
ric softeners for clothes dryers, masonry acid wash-
ing materials.
If a unit is to be installed on a roof curb other than a
UP roof curb, gasketing must be applied to all sur-
faces that come in contact with the unit underside.
Before lifting, make sure the unit weight is distrib-
uted equally on the rigging cables so it will lift evenly.
All panels must be secured in place when the unit is
lifted.
The condenser coils should be protected from rig-
ging cable damage with plywood or other suitable
material.
