HORIZONTAL LEFT

a. 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.
b. For maximum efficiency, remove the factory in-
stalled baffle assembly from the apex of the coil by
using a nutdriver to remove the 5/16" hex head
screw. For the TEE3F40-66 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 9.
▲
CAUTION
!
When installing the narrow coil baffle, make sure to
align the baffle up with the holes so NOT to puncture
the coil tubing.
c. 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 re-
attach coil support tab.
d. 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 suspended
at both ends. See Figure 11.
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.
e. 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.
f. Isolate the auxiliary drain pan from the unit or
from the structure.
g. 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.
h. If a return duct is connected to the air handler, it
must be the same dimensions as the return open-
ing shown in the outline drawing on page 13.
i. On units with sheetmetal returns: Return
plenum should be flanged. Sheetmetal screws
must be 1/2" in length or shorter.
j. No sheetmetal screws may be used to attach
return ductwork on the side of the unit.
k. Openings where field wiring enters the cabi-
net must be completely sealed.
Location of power entry is shown on the outline
drawing. Use 2.5" clear stickers provided to seal
all unused electrical knockouts. See Figure 8.
l. After ductwork connections are made, seal air-
tight and per Local codes.
