7. Start each mounting bolt through the ceiling tem-
plate and up into the unit base pan by hand. Install
wood screw in each end of the ceiling template.
This insures a tight fit of the return air cover to
ceiling. See FIG. 11.
Evenly tighten the four mounting bolts to a
torque of 40 to 50 inch pounds. This will com-
press the roof gasket approximately 1/2". The
bolts are self locking so further tightening is
not necessary. See FIG. 11.
8. Installation of Divider Plate
a. Measure the ceiling to roof thickness:
• If distance is 2.0" - 3-3/4", remove perfo-
rated tab from divider plate.
• If distance is 3-3/4" - 5-1/2", remove no
tabs.
b. Remove the backing paper from double sided
tape located on ceiling template. See FIG. 12.

If bolts are left loose there may not be an ad-

may occur to the unit base or ceiling template.
Tighten to torque specifications listed in this
manual.

c. Place divider plate up to bottom of the unit base
pan firmly. The foam tape on the divider plate
must seal to bottom of base pan. See FIG. 13.
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 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. 14.
• Excess width is intended to seal the divider
plate to the sides of the 14-1/4" x 14-1/4"
(±1/8") opening. This is to help prevent
cold air discharge from circulating into the
unit return air opening.
• If the insulation is too high, stick excess
height of insulation to the unit base pan.
Do not cover up unit rating plate.
FIG. 13
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 cooling.
