4. Place on a level surface in the position it was
removed from the unit.
5. Remove the plug knockout in the bottom of the
drain pan to convert it to through the base
drainage.
6. Plug the original condensate drain opening with a
field supplied 3/4" NPT plug.
7. Slide the condensate drain pan back into the unit,
align the drain support with the grommeted
opening in the rear support panel and push until the
support is seated in the grommet.
8. Replace the front support panel by aligning the
panel with tabs in the raceway. Align the plugged
condensate drain pan coupling in the grommeted
hole as the panel is put in place.
9. Replace evaporator access panel and supply air
access panels.
A condensate trap must be installed at the unit due to
the drain connection being on the "negative pressure"
side of the fan. Install the P-Trap using the guidelines in
the figure below.

Drain Pan Removal (Units with
Condensate Overflow Switch Option)
Before drain pan removal, the switch wire must be
disconnected from wire tie on panel and/or any tape
before drain pan can be removed.
Care must be taken so the wire does not catch on the
bottom of indoor coil or any protrusion.
N N o o t t e e : : When reversing the drain pan, on some units, the
condensate overflow switch will need to be
moved to the second hole in its bracket to avoid
contact with headers or indoor coil.

Filter Installation

Each unit ships with 2 inch filters installed. The quantity
of filters is determined by unit size. Access to the filters
is obtained by removing the filter access panel.
Refer to the unit Service Facts (shipped with each unit)
