6.1 Upflow Installation
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, re-
move the two (2) screws that secure the drip shield support
brackets to the condensate collectors (front and back). Unsnap
the side drain pan from the main 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 application
and condensate drain line must be attached to this drain port.
Drain port (a) is for the secondary drain line (if used).

6.2 Horizontal Left Installation
No field modifications are permissible for this application.
The bottom right drain connection is the primary drain for
this application and condensate drain line must be attached
to this drain connection. The top connection of the three
drain connections on the drain pan must remain plugged for
this application. The bottom left drain connection is for the
secondary drain line (if used).
In applications where the air handler is installed in the horizon-
tal left position, and the return air environment see humidity
levels above 65% relative humidity 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 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 Goodman distributor. The DFK is not supplied with
the air handler and is required by Goodman on all downflow
installations. See Table 2 for the correct DFK and follow the
instructions provided for installation.

Refer to Figure 6 and 7 for the location of the components
referenced in the following steps.
1. Before inverting the air handler, remove blower access
panel and coil access panel. The coil access panel and
tubing panel may remain screwed together during this pro-
cedure. Remove and retain the seven (7) screws securing
the coil access panel to the cabinet and the six (6) screws
securing the blower access panel to the cabinet.
2. Slide the coil assembly out using the drain pan to pull the
assembly from the cabinet.
NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO
PULL THE COIL ASSEMBLY OUT. FAILURE TO DO SO MAY
RESULT IN BRAZE JOINT DAMAGE AND LEAKS.
3. Removal of the center support is required on units with
21" wide cabinet. Remove and retain the two (2) screws
that secure the center support to the cabinet. Remove the
center support.
4. Using the drain pan to hold the coil assembly, slide the coil
assembly back into the cabinet on the downflow brackets
as shown in Figure 8.
5. Re-install the center support (if removed) using the two (2)
screws removed in Step 4.
6. Re-install the access panels removed in Step 1 as shown in
Figure 9.
