INSTALLATION INSTRUCTIONS
6. 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. See (FIG. 14).

(FIG. 14).

Paper Backing
c.  Divider plate MUST be in-
stalled correctly. Incorrect installation could
cause compressor to quick-cycle, and could
result in supply circuit overload and reduced
product performance.
 T he adhesive on the double-sided
tape is extremely sticky. Make sure
the divider plate is properly positioned
before pressing into place.
Place the divider plate up to bottom of the
unit base pan firmly. The foam tape on the di-
vider plate must seal to bottom of base pan.
See (FIG. 15).

● Excess width is intended to seal the di-
vider plate to the sides of the roof open-
ing. This is to help prevent cold air dis-
charge from circulating into the unit return
air opening.
● If the insulation is too high, stick excess
height of the insulation to the unit base
pan. Do not cover up unit rating plate.
f. Place the electronic control box on the ceil-
ing template with the white 6 pin plug on the
curb side of the RV. Do NOT attach at this
time.
g. Plug the 6 pin connector into matching 6 pin
connector in the electronic control box. The
plug is polarized and will only fit in one direc-
tion. See (FIG. 18).
h. Plug the supplied freeze control sensor and
the 4 wire harness into their matching con-
nectors in the electronic control box.
i. Insert the freeze control sensor into the
evaporator coil fins approximately 1" above
