Unit Placement
For proper operation, the unit must be installed level (zero
tolerance) in both horizontal axes. For vertical discharge
units, allow space under the unit for supply air ductwork
connections.
Each section must be individually hoisted, set on the
housekeeping pad, roof curb, or pier mount and then
assembled. Individually place each section in the
appropriate installation location.
Note:
Prior to placing fan section in the appropriate
installation location, verify shipping tie-downs
have been removed.
Floor Mounting for Indoor Units
The skid tie down brackets can be used to tie down the unit
to the concrete slabs or other flat surface. Do not use tie
downs to lift the unit.
Ceiling Suspension for Indoor Units
Using a Field-Provided Mounting Frame
If a field-provided mounting frame is used for ceiling
suspension, the installer/contractor must provide a
ceiling-suspended mounting frame designed to support
the length, width, and weight of the entire air-handling
unit. See the Dimensions and Weights chapter for
approximate weights.
Note:
It is the building engineer’s responsibility to size the
structural channels and to provide the appropriate
hangers.
Structural channels in a field-provided frame can be
mounted parallel to airflow or perpendicular to airflow:
WARNING
Toxic Fumes!
Keep open flame away from unit exterior or interior. Do
not weld or use cutting torch on the exterior or interior
of the unit. The unit contains polyurethane insulation.
Flame could produce toxic gas which could result in
death or serious injury.
NOTICE
Equipment Damage!
Failure to comply with temperature requirements could
result in equipment damage. The internal sections of
this unit containing electrical components must not
exceed 104o F operating temperature. Internal sections
of the unit which do not contain electrical components
must not exceed 200°F temperature.
NOTICE
Microbial Growth!
Standing water and wet surfaces inside the equipment
can become an amplification site for microbial growth
(mold), which could cause odors and damage to the
equipment and building materials. The floor or
foundation must be level and the condensate drain at
the proper height for proper coil drainage and
condensate flow.

WARNING
Risk of Unit Dropping!
Improper use of the tie down brackets could result in
unit dropping and crushing technicians which could
result in death or serious injury, and equipment
damage. Do not use skid tie down brackets to lift the
unit. Tie down brackets are designed only to secure the
unit to the floor, housekeeping pad, or platform.
