Instructions

STEP 9 Starting with the back of the
AC coil, place a piece of sheet metal
from the kit centered and upright,
resting on the top of the coil.
STEP 10 Mark the 4 corners, both
vertically and horizontally where the
sheet metal will intersect with the
furnace and supply plenum. Be sure
to mark the orientation of the sheet
metal so when it’s take down for
cutting, it goes back facing the same
direction.
STEP 11 Draw a straight line from
each corner mark to form a box.
STEP 12 Add an additional 1” to the
sides and 1/2” to the top to allow for
corner overlaps. Leave the bottom
line as is.
STEP 5 Measure the length of each
edge for both the top of the AC coil
and the bottom of the supply ple-
num. The 8 S-Drives will be tted on
these edges to hold the sheet metal.
STEP 6 When cutting each S-Drive,
subtract 1/8 inch from each side for
allowance on the corner joints. NOTE:
The metal snips may crush the ends.
Use a screwdriver to gently open.
STEP 7 Place each S-Drive on the lip
on top of the new AC coil, as shown.
Repeat for all 4 sides along the bot-
tom with the “U” shaped channel on
the outside for each side.
STEP 8 Prepare to measure the sheet-
metal sides by noting the (1) back,
followed by the (2) front. Then the (3)
left side, nishing with the (4) right
side.
