a. Before installing unit, remove thumbscrews to
the filter panel. Carefully remove the COLLEC-
TION CELL by grasping the leading edge of the
frame. See Figure 6. Set aside in a safe place un-
til the unit is set in place and ready to start up.
b. Use a 5/16" nutdriver to remove the screws in
the FIELD CHARGER retainer and take out
both. Slightly lift the FIELD CHARGER and care-
fully remove. Set aside in a safe place until the
unit is set in place and ready to start up. See Fig-
ures 7 and 8.

c. Position unit to remove the bottom protector
plate by laying the unit on its back. Use a flat
blade screwdriver between the protector plate
and the unit to pry apart. See Figure 9. Gently
pull the plate towards the front of the unit to re-
move.
d. To convert the unit to horizontal left, front ac-
cess, slide the coil out on the coil channel sup-
ports and rotate the complete coil 180 degrees.
e. For maximum efficiency, remove the factory
installed baffle assembly from the apex of the coil
by using a 5/16" nutdriver to remove the hex
head screws. For the TEE3D40-65 units, there is
a coil support tab at the top of the coil connected
to the case must be removed first. Replace this
baffle with the factory supplied narrow coil baffle
using the screws removed previously. See Figure
15.

CAUTION
!
When installing the narrow coil baffle, make sure to
align the baffle up with the holes so NOT to puncture
the coil tubing.
f. The coil is then inserted back into the cabinet on
the opposite side coil channel supports. The unit
is now horizontal left with front access. Do not
reattach coil support tab.
g. If the unit is suspended, it must be supported
from the bottom near both ends as well as the
middle to prevent sagging. The service access
must remain unobstructed. If the unit is sup-
ported along the length of the front and back
with rails, the air handler only needs to be sus-
pended at both ends. See Figure 13.
If the unit is not suspended it must be supported
as mentioned above and isolated carefully to pre-
vent sound transmission. Vibration isolators (pur-
chased locally) must be placed under the unit.
h. It is always recommended that an auxiliary drain
pan be installed under a horizontal air handler
(See Condensate Piping) to prevent possible dam-
age to ceilings.
i. Isolate the auxiliary drain pan from the unit or
from the structure.
j. Connect the auxiliary drain line to a separate
drain line (no trap is needed in this line) and ter-
minate according to National and Local codes.
k. If a return duct is connected to the air handler, it
must be the same dimensions as the return
opening shown in the outline drawing on page
20.
l. On units with sheetmetal returns: Return
plenum must be flanged. Sheetmetal screws
