FIG. 7 –
SPLICE KIT FOR SHIPPING SPLIT ASSEMBLY
Do not apply Butyl tape to both sides
of the split. The double thickness will
cause the seam caps not to fit properly.
3. The segment opposite the top rail splice channel,
that extends from inside the top rail, will need to
have the first 3 or 4 screws from the top of the wall
panel removed on both sides of the unit. This will
aid in bringing the segments together.
4. Slide segments into place, aligning the perimeters
of each segment. An aid has been provided for ease
of alignment, these are the bolt holes in the lifting
brackets at the bottom of the unit. Slide top rail
splice channel into the other top rail and bring seg-
ments together.
5. Once the segments are together, climb inside the
unit and put the splice kit top rail into place. Align
holes from splice rail to the top rail, then into the
top rail splice channel. This is accomplished by us-
ing a drift pin. When the holes are aligned, run a
1/2" self-tapping hex head bolt (supplied) into the
holes on both sides of the unit.
6. In the splice kit top and bottom rail there are holes
that should be aligned with the other segment. Place
a 1/2" bolt in the adjoining holes using a fender
washer on both sides, a lock washer and a nut.
Place bolts and hardware into every hole.
7. Replace screws in wall panel that were removed in
Step 3.
8. Apply caulking and place roof seam cap onto raised
seam. Then bend the end piece down and run a
self-drilling screw into the hole supplied.
9. Apply caulking and place wall seam cap onto raised
seam. Then run self-tapping phillips head screw into
the supplied holes.
INSTALLING UNIT ON CURB
1. Units should not be moved over a roof covering but
should be lifted from the ground onto the curb or
support framework.
The curb gasket which is provided
must be installed before the unit is
lowered on the curb. The gasket is
shipped with the curb package.
2. SEAL (to curbing): When setting the unit onto the
curb, the installer should ensure that a sealing
gasket is positioned between the unit and curb
to provide a continuous airtight and watertight
connection.
3. The base of curb mounted units extend beyond the
curb.
4. Installation should be in accordance with local code
requirements.
ISOLATORS
The standard fan isolation consists of rubber-in shear
(See Figure 8) or spring isolators (See Figure 9) mounted
under the internal fan assembly.
Optional seismic isolators mounted under the fan are
also offered. (See Figures 12 and 13)
Fan Isolators must be prepared for operation:
1 . Loosen tie down bolts and/or remove the shipping
blocks from the blower/motor frame.
2. Check blower/motor frame for correct height and
that the frame is level.
