Location
All models are approved for alcove, closet, and attic installation
in the upflow, downflow or horizontal position. Refer to the
applicable section of this manual on pages 3-5 for specific
installation instructions on each position.
The air handler must be installed in a level position and should
be located for ease in connecting air duct with proper air
distribution.
Exterior surface of cabinet may sweat when unit is installed in
non-air-conditioned space such as attic or garage. Installer must
provide protection such as full-size auxiliary drain pan on all
units. Be sure to allow for filter access for periodic user servicing.
In addition, caulking must be applied around the power and
control wires entering the control box. This will prevent air
leakage into and condensate from forming inside the control
box.
Clearances
Clearances from the air handler to the combustibles are zero
inches from all sides, top, and bottom; one inch from discharge
air plenum; and the duct within 36 inches of the plenum.
Provide adequate space for servicing the air handler; at least 30
inches. All service and maintenance can be performed from the
front access doors of the air handler.
