6 Installation Location
NOTE: These air handlers are designed for indoor instal-
lation only.
The AVPEC product line may be installed in one of the up-
flow, downflow, horizontal left or horizontal right orientations
as shown in Figures 3, 4, 5 and 6. The unit may be installed
in upflow or horizontal left orientation as shipped (refer to
specific sections for more information).
Minor field modifications are necessary to convert to down-
flow or horizontal right as indicated in below sections.
6.1 Upflow Installation
No field modifications are mandatory however to ob-
tain maximum efficiency, the horizontal drip shield, side
drain pan and drain pan extension, can be removed.
Side Drain Pan and Extension Removal: Refer to
Figure 1, remove the two (2) screws that secure the
drip shield support brackets to the condensate collec-
tors (front and back). Unsnap the side drain pan from
the bottom drain pan using a screw driver or any small
lever. The side drain pan, drip shield brackets and the
drain pan extension may now be removed. From Figure
1, drain port labeled (A) is the primary drain for this ap-
plication and condensate drain line must be attached to
this drain port. Drain port (a) is for the secondary drain
line (if used).
If the side drain pan is removed, the drain port opening
in the access panel must be covered by the accessory
drain port plug (DPK1) as shown in figure 1.1.
6.2 Horizontal Left Installation
No field modifications are permissible for this
application.
Drain port labeled (B) in Figure 1 is the primary drain
for this application and condensate drain line must be
attached to this drain port. Drain port (b) is for the sec-
ondary drain line (if used).
In applications where the air handler is installed in the
horizontal left position (←), and the return air environ-
ment see humidity levels above 65% relative humid-
ity coupled with total external static levels above 0.5"
e.s.p., a condensate kit is available for field application.
Kit nomenclature can be found in the table 1.
6.3 Downflow/Horizontal Right Installation
IMPORTANT NOTE: In the downflow application, to
prevent coil pan "sweating", a downflow kit (DFK) is
available through your local distributor. The DFK is not
supplied with the air handler and is required to minimize
pan sweating on all downflow installations. See Table 2
for the correct DFK and follow the instructions provided
for installation.
Refer to Figure 7 and 8 for the location of the compo-
nents referenced in the following steps.
