RECONNECT INSTALLATION PROCEDURE
1. Position sections on level surface.
2. Apply polyurethane caulk in two parallel continuous beads
on both faces as indicated in Figures 15, 16 and 17.
3. Attach hand winches to either side of the base via relocated
lifting lugs and pull the sections together. Bolt the base flanges
per Figure 15.
ASSEMBLY HINT
It may be advantageous to locate the first AcuAir unit
section in its final position and attach it to the support
structure before pulling the next section into position
against it.
4. The factory installed unit reconnect flanges will be joined
using ¼” bolts and nuts shipped loose in a container in the
blower section of the unit. All bolt holes require a bolt.
If bolt holes do not align, it may be due to racking during
transit to job site. Use a 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.
Continue assembly with bolting other side, base, and roof,
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. Check to see if all bolts are secured properly, and apply
polyurethane caulk to all exterior seams per Figures 18.
ASSEMBLY HINT
It is recommended that the base flange bolts be only
loosely fitted prior to fitting all 1/4" reconnect external
flange bolts. Once all of the 1/4" flange bolts are in place,
tighten the base flange bolts and finish tightening all of
the reconnect flange bolts. This sequence will help make
alignment of the reconnect flange holes a bit easier.
6. Apply two continuous .25” dia. beads of caulk on either
side of the floor section split. Reference either the lower left
or the lower right views of Figure 15.
7. Center the split cover over the floor split and two parallel
beads of caulk. Attach the split cover using #12 TEK screws.
It may be necessary to predrill holes through the base flange
for the TEK screws.
8. Seal the edges of the split cover with beads of caulk as
shown in Figure 15.
9. Inspect all splits to see if polyurethane caulk was applied
and split was bolted properly.
10. 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)
11. Inspect all splits to see if all electrical and piping
connections are complete and correct.
