Heat Wheel Modules
Coils and heat wheels slide out for easier servicing.
There should be enough clearance left on one side of
the unit (usually the piping connection side) to
completely remove the coils and heat wheel for
maintenance or replacement.

Mounting & Suspension
Celebrity TM air handlers can be designed for horizontal
or vertical airflow applications, and can be floor
mounted or suspended. Units may be delivered in
separate module components, or completely factory
assembled with all modules connected. In the latter
case, if the unit was received fully assembled on a
skid, then the equipment should be lifted into place
using the shipping skid to prevent damage to the
modules.
Floor Mounted
Make sure the unit is level, and installed with a
minimum height of 6” to allow for proper drainage of
the condensate line. Other installation provisions may
be necessary according to job specifications.
Suspended
Modular air handlers are equipped for suspended
installations. All modules must be connected and the
unit must be completely assembled before the unit is
lifted into position. The base of the unit must be
supported before hoisting. Do not lift the unit by any
part other than the unit base.
Unit base rails are manufactured with suspension rod
holes. To suspend an assembled unit, insert support
rods through the aligned base rail holes on both sides
of the unit. Secure suspension lines to the rods and to
an overhead support structure. The air handler must
be installed level as the internal drain pan is
manufactured with a slope toward the drain. Be sure
not to obstruct service access doors with the
positioning of the suspension lines. Other installation
provisions may be necessary according to job
specifications and requirements.
NOTE
An auxiliary (emergency) drain pan is
recommended for all applications where there is a
risk of water damage to surrounding structure or
furnishings. Refer to local codes.
