Mount Unit
Unit can stand or lie on floor, or hang from ceiling or wall. Allow space for wiring, piping and servicing unit.
Important:
When unit is installed over a finished ceiling and/or living area, building codes may require a field-
supplied secondary condensate pan installed.
Under the entire unit. Some localities may allow as an alternative the running of a separate secondary condensate
line. Consult local codes for additional restrictions or precautions.
A. Upflow Installation:
If return air is to be ducted through a floor, set unit on floor over opening and use 1/8”
to 1.4” inch thick fireproof resilient gasket between duct unit and floor. Cut opening as per dimensions (See
Fig. 1). A field supplied bottom closure is required.
B. Downflow Installation:
In this application, field conversion of the evaporator coil is required, using
accessory downflow kit. Along with an accessory base kit. See installation instructions packaged with
accessory kits. See product data for kit pan numbers.
C. Horizontal Installation:
Units must not be installed with access panels facing up or down. All other units
are factory built for horizontal left installation. When suspending unit from ceiling, dimples in casing indicate
suitable location and screws for mounting metal support straps (See Fig. 2).

Note:
Modular units can be dissembled and components moved separately to installation area for reassembly. This
process accommodates small scuttle holes and limiting entrances to installation sites. (See Fig. 3.)
For optimum condensate drainage performance in horizontal
installations, unit should be leveled along its length and width.
