3) Refer to FIGURE 40E. On the leg of the downturn plenum next to the cooling
coil cabinet locate the mounting screw illustrated. Measure up 6" (152mm). At
same centerline as the screw, drill the first 7/8" hole.
Second Hole:
1) Remove the cooling coil access panel(s).
2) Locate the coil blockoff plate. Measure up 4" (102mm) from the bottom of the
blockoff plate. At that location, find the center point of 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 cabinet, 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 40F.
