Opening
8. 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.
a. Finger-tighten the bolts and check alignment.
There should be an equal opening on each side
and the rear flange must be tight against the roof
opening.
b. EVENLY tighten the three bolts to a torque
of 40 to 50 inch pounds. This will compress
the roof gasket to approximately 1/2". The
bolts are self locking so over tightening is
not necessary.

Disconnect 120 volt AC. Failure to follow these
instructions could create a shock hazard caus-
ing death or severe personal injury.
WARNING
!
Reach up into the return air opening and pull the re-
maining wires down.
