!0. Make sure there are provisions for installing conden-
sate drain lines.
!1. If side, front or rear return is required, air handler
must be elevated or placed on a plenum (TAYPLNM100
or 101). Connecting return duct directly to the side,
front or rear of the cabinet is not approved.
12. Route refrigerant and condensate drain lines away
from air handler so they do not interfere with access
panels and filters.
13. When external accessories are used, the additional
height and width requirements must be considered in
the overall space needed.
14. These units are not approved for outdoor installation.
15. These units are approved for draw-through applica-
tion only.

by removing the two screws at the drain pan and
the two screws holding the two brackets at the
top of the coil.
b. Remove the factory installed baffle assembly
from the apex of the coil by removing the 5/16"
hex head screws.

it must be the same dimensions as shown in the
outline drawing.
e. Pedestal and unit should be isolated from the
foundation using a suitable isolating material.
DOWNFLOW
a. For maximum efficiency, the horizontal drip
tray should be removed. Tray removal requires
that the coil be removed by sliding the coil out on
the coil channel supports. The tray is detached
by removing the two screws at the drain pan and
the two screws holding the two brackets at the
