The ARUF**14** and ASPT**14** product lines may be in-
stalled in one of the upflow, downflow, horizontal left or hori-
zontal right orientations as shown in Figures 2, 3, 4 and 5. The
unit may be installed in upflow or horizontal left orientation as
shipped (refer to specific sections for more information).
No field modifications are mandatory. However, to obtain
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 sup-
port brackets to the condensate collectors (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 re-
moved. From Figure 1, drain port labeled (A) is the primary
drain for this application and condensate drain line must be
attached to this drain port. Drain port (a) is for the second-
ary 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.

SIDE DRAIN PAN REMOVAL
6.1 Upflow Installation
No field modifications are mandatory.
6.2 Horizontal Left Installation
No field modifications are permissible for this application.
Install unit as shown in Figure 4.
Remove red plugs from side drain pan before connecting
condensate drain pipes. Use removed plug to close drain
ports on vertical drain pan. The bottom right drain connec-
tion in side drain pan is the primary drain for this application
and condensate drain line must be attached to this drain
connection. The bottom left drain connection in side drain
pan is for the secondary drain line (if used).
In applications where the air handler is installed in the hor-
izontal left position, and the return air environment see hu-
midity levels above 65% relative humidity coupled with to-
tal external static levels above 0.5" e.s.p., a condensate kit
is available for field application. Kit nomenclature can be
found in Table 2.
