6. Prepare Cabinets to Install Filler Panels (See FIGURE 46H)
a) At the side corners of both the cooling coil cabinet and the
furnace, remove the factory-installed screws that attach the
cabinet tops.
b) Across the edge of the cooling coil cabinet, remove the row of
screws that attach the top.
the blockoff plate and drill a 7/8" hole. The hole should be
approximately even with the hole drilled in the downturn
plenum leg.
Third Hole:
On the cabinet leg on the entering air side of the cooling coil cabi-
net, measure up 10" (254mm) from the bottom pan. At that height,
measure in 4" (102mm) from the edge and drill a 7/8" hole.
b)
On the outside of the furnace section
(where the flanges were joined in Step 4),
locate the three hole plugs. Remove the
center plug exposing a 7/8" hole in the
cabinet leg. See
FIGURE 46F
.
c)
Run the wires attached to the damper mo-
tor 1) out through the hole in the dis-
charge plenum leg into the cooling coil
cabinet, 2) through the blockoff plate,
across the coil cabinet, 3) out through the
hole in the cooling coil cabinet leg, and 4)
into the furnace section.
d)
On the bottom of the electrical box in the furnace section, remove the
hole plug that is below the terminal blocks. Route the damper motor
wires up through the hole and into the electrical box. Attach accord-
ing to the connections on the wiring diagram. Refer to sample in
FIGURE 46G
.
7. Install the Cabinet Side Filler Panels (See FIGURE 46J)
Place a piece of the supplied insulation against the inner panel of the
cooling coil cabinet. Slide the filler panel into place and attach with
1/2" sheetmetal screws. Repeat on the other side. NOTE: It may be
easier to slide the filler panels in place with the door panels re-
moved.
