duct over the upper duct.

k. Hold the ceiling template with one hand and with
the other, install the three 1/4" mounting bolts
through the template and into the base pan.
•
Finger-tighten the (3) bolts and check align-
ment. There should be an equal opening on
each side and the rear flange must be tight
against the roof opening.
•
EVENLY tighten the bolts to a torque of
40 to 50 inch pounds. This will com-
press the roof gasket to approximately
1/2". The bolts are self locking so over
tightening is not necessary.
If bolts are left loose there may not be an ad-
equate roof seal or if over tightened, damage
may occur to the air conditioner base or ceil-
ing template. Tighten to torque specifications
listed in this manual.
H. Wiring Of System
Reach up into the return air opening and pull the remaining
wires down. See FIG. 13.
1. Connection Of Low Voltage Wires
Disconnect the positive (+) 12 volt DC termi-
nal at the supply battery. Damage to equip-
ment could occur if the 12 volt DC is not shut
off.
a. Route Remote Temperature Sensor cable, if
applicable, and attach it to the connector that
matches its color protruding from the return air
opening.
