1. Position sections on level surface.
2. Install the foam gasket on one of the mating surfaces of
one of the sections to be reconnected as indicated in Figure 17.
Gasket material and caulk are shipped loose in boxes located
in the blower section of the air unit.
3. Apply a bead of polyurethane caulk to either side of
the foam gasket and across the lower reconnect ange as
indicated in Figure 17.
4. Attach hand winches to either side of the base via relocated
lifting lugs and pull the sections together. Bolt the base anges
per Figure 15.
5. The factory installed unit reconnect anges 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.
6. Check to see if all bolts are secured properly, and apply
polyurethane caulk to all exterior seams per Figures 18.
7. Apply gasket tape to either side of the section joint on the
interior oor of the unit as indicated in the details of Figure 15.
8. Center the split cover over the gasket tape and the joint
to be covered. Attach the cover using the #12 TEK screws. It
may be necessary to predrill holes through the base ange
for the TEK screws.
9. Seal the edges of the split cover with beads of caulk as
shown in Figure 15.
10. Inspect all splits to see if polyurethane caulk was applied
and split was bolted properly.
