Position coil cabinet in relation to the blower so they will be correct
for desired application.
For upflow and horizontal applications apply foam seal strip around
top of coil cabinet. For downflow application apply foam seal strip
around bottom of coil cabinet. Set blower on top of coil cabinet so
they are flush. Secure cabinets together using the three tabs on the
bottom of the cabinet. Bend the tab out from the bottom so it fits over
the coil cabinet. If no pilot holes are present, drill a hole as required
for a screw.

NON-DUCTED RETURN AIR CLOSET
INSTALLATION
The cabinet can be installed in a closet with a false bottom to form a
return air plenum, or mounted on an open platform inside the closet.
Platform should be high enough to provide a free (open) area for
adequate return airflow into the bottom of the cabinet. The open area
can be on the front side or a combination of front and sides, providing
there is clearance on the sides between cabinet and closet. Refer to
ACCA Manual D for sizing and free area recommendations.
NOTE:
Local codes may limit application of systems without a
ducted return to single story dwellings.
HORIZONTAL LEFT AND RIGHT
INSTALLATIONS
The air handler cabinets can be installed in either downflow,
horizontal left or horizontal right applications. When a coil cabinet is
applied, refer to the coil installation manual for proper drain pan and
airflow requirements. They must have the drain pan repositioned for
right hand airflow. Refer to coil installation manual.
CAUTION
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in property
damage.
A field fabricated auxiliary drain pan, with a separate drain
is REQUIRED for all installations over a finished living
space or in any area that may be damaged by overflow
from a restricted main drain pan. In some localities, local
codes require an auxiliary drain pan for ANY horizontal
installation.

SUSPENDED CABINET INSTALLATION
1. The cabinet may be supported on a frame or shelf, or it may be
suspended.
2. Use metal strapping or threaded rod with angle iron supports
under the auxiliary drain pan to suspend cabinet. These supports
MUST run parallel with the length of the cabinet. Refer to Figure
5.
3. Ensure that there is adequate room to remove service and
access panels after installing supporting brackets.
4. Place field installed vibration isolators in auxiliary drain pan to
support cabinet.
