GENERAL INFORMATION
1. IMPORTANT: If installing the unit
over a finished ceiling or living
area, be certain to install an
auxiliary condensate drain pan
under the entire unit. This
auxiliary drain pan should extend
under any evaporator coil
installed with the air handler and
the open portion of the
condensate drain assembly.
2. IMPORTANT: If using a cooling
evaporator coil with this air
handler:
Be sure the air passes over the
coil/pump before passing over
the cooling coil.
IMPORTANT: Support this unit
when installed. Since this air
handler is suitable for attic or
crawl space installations, it may
be installed on combustible wood
flooring or by using support
brackets. See Figure 5.
5. IMPORTANT: If installing in a
utility room, be sure the door
is wide enough to:
a. allow the largest part of the air
handler to pass; or
b. allow any other appliance
(such as a water heater)
to pass.
6. IMPORTANT: This air handler is
not approved or recommended
for installation on its back, with
access doors facing upwards
(see Figure 3).
CLEARANCE -
ACCESSIBILITY
The design of air handlers with input
ratings as listed in the tables under
Figure 4 are certified by UL for the
clearances to combustible materials
shown in inches.
See name/rating plate and clearance
label for specific model number and
clearance information.
Service clearance of at least 24” is
recommended in front of
all air handlers.
NOTE: Use recommended 24”
clearance if accessibility clearances
are greater than fire protection
clearances.
Air handlers are shipped with a
bottom closure panel installed.
When bottom return air is used,
remove the panel by removing the
two screws attaching the panel to
the front base angle.
SITE SELECTION
1. Select a site in the building near
