INSTALLATION
REASSEMBLY PROCEDURE FOR SPLIT UNIT
PERFORMANCE SERIES ONLY
1. Position sections on level surface.
2. Apply polyurethane caulk in two parallel continuous beads
on both faces as indicated in Figures 9, 10 and 11.
3. Attach hand winches to either side of the base via relocated
lifting lugs and pull the sections together. Bolt base per Figure 9.
ASSEMBLY HINT
It may be advantageous to locate the first section in
it's final position and attach it to the support structure
before pulling the next section into position.
4. Install the reconnect flange attachment hardware starting
from the middle of the bottom angle working around to the
middle of the top angle, making use of a drift pin to align the
holes. Bar clamps may be needed to align the roofs together.
If bar clamps are needed, use wood for protection in between
the bar clamp and unit.
5. Split seams that have internal access to both sides of
split will be reattached with bolts and nuts. Split seams with
internal access to only one side of split will have cage nuts
on the blind side and bolts installed from accessible side. All
bolt holes require a bolt.
6. If bolt holes do not align, it may be due to racking during
transit to job site. Use jack to lift one side until holes on the
wall of the opposite side align. Bolt this wall together and
then remove jack from opposite side. As the unit settles, the
out-of-square racking caused during transit should realign.
7.
Once the sections are drawn together and the reconnect flanges
are aligned and attached, apply two parallel beads of caulk along
either side of the reconnect seam on the exterior of the AcuAir unit
as shown in
Figure 13.
8. Install the shipping split covers as shown in Figure 13 using
the #10 TEK screws and washers provided. Apply a fine bead
of caulk to either edge of the split cover and allow time to dry.
9. Once the shipping cover is in place and the caulk has had
time to set, apply the roof coating as shown in Figure 14.
10. INSPECT all splits to see if polyurethane caulk was applied
and split was bolted properly.
11. Reconnect all electrical conduit and wiring at the
reconnect junction boxes. Use electrical conduit sealing putty
to seal all conduit openings into and out of the junction box to
prevent the migration of moisture. (reference the information
on page 42)
12. INSPECT all splits to see if all electrical and piping
connections are complete and correct.
NOTICE
Temporary roof supports and diagonal (shipping) sup
-
ports should not be removed until the split sections are
completely reassembled.
