INSTALLATION INSTRUCTIONS
6.DISCHARGE DUCT & CEILING TEMPLATE INSTALLATION
A.Remove the air box and mounting hardware from their carton. The upper duct is shipped inside the lower duct
which is part of the ceiling template.
FIG. 8
B.Remove the upper duct from the ceiling template and locate it over the blower discharge.
Note: The edge without the flange installs toward the rear and side of the opening.
C.Use two of the sharp pointed sheet metal screws to hold the duct to the base pan. The holes are
the pan for each location.
D.Check gasket alignment over roof opening and adjust if necessary (roof gasket centers over opening). Unit may
be moved from below by lifting and sliding.
E.Reach up into the return air opening and pull the conduit power cable down for later connection. See FIG. 9.
F.Measure the ceiling thickness:
1.If the distance is 2” to 3” remove the perforated tabs from the bottom duct only.
2.If the distance is 3” to 4” install ducts as received.
3.If the distance is 4” to 6” (maximum thickness), optional Duct Kit and Bolt Kit are available:
Duct Kit | (Part No. 3106775.004) |
Bolt Kit | (Part No. 3100895.006) |
G.Take the ceiling template and slide the lower unit over the upper duct.
H.Hold the ceiling template with one hand and with the other, install the four 1/4” mounting bolts through the template and into the base pan. See FIG. 10.
1.
the rear flange must be tight against the roof opening.
2.Evenly tighten the bolts to a torque of 40 to 50 inch pounds. This will compress the roof gasket to ap-
proximately 1/2”.

FIG. 9
If bolts are left loose there may not be an adequate roof seal or if over tightened, damage may occur to the air conditioner base or ceiling template. Tighten to torque specifications listed in this manual.
