Improper installation and sealing of divider
plate will cause the compressor to quick cycle
on the cold control. This may result in fuse or
circuit breaker opening and/or lack of cool-
ing.
CAUTION
c. Place divider plate up to bottom of air condi-
tioner base pan firmly. The foam tape on the
divider plate must seal to bottom of base pan.
See FIG. 17.
Note: The adhesive on the insulation is extremely sticky.
Be sure the part is located where desired before pressing
into place.
d. With slight pressure then push the divider plate
against the double sided tape on the ceiling
template.
e. Locate the 1/8” x 7” x 18” self -adhesive insula-
tion supplied with the return air kit. Remove the
backing paper from the insulation and carefully
stick onto the ceiling template divider panel.
See FIG. 18.
Excess width is intended to seal the di-
vider plate to the sides of the 14-1/4" x 14-
1/4" (±1/8") opening. This is to help pre-
vent cold air discharge from circulating into
the air conditioner return air opening.
If the insulation is too high, stick excess
height of insulation to the air conditioner
base pan. Do not cover up unit rating plate.
