Unit Placement and Assembly

• If the air handler is ordered with a mixing box or angle
filter section, it will arrive in sections. Some assembly
may be required. For details, see:
• Section assembly; see
• Ceiling-suspended indoor unit assembly; see
Suspension, " page 22.
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!
The internal sections of this unit containing electrical
components must not exceed 104
temperature. Internal sections of the unit which do not
contain electrical components must not exceed 200
temperature. Failure to comply with temperature
requirements could result in equipment damage.

Unit Placement

NOTICE:
Microbial Growth!
The floor or foundation must be level and the
condensate drain at the proper height for proper coil
drainage and condensate flow. 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.
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 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

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.

Risk of Unit Dropping!
o
F
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. 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.
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 "Dimensions and Weights" on page 14
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:
• For parallel-to-airflow channels, size channels based
on a four-point load distribution.
• For perpendicular-to-airflow channels, size channels
based on the load distribution of the individual
sections and install the channels so that both ends of
every section are supported.
