Reassembling Split Units
Some RZ Series units are built and shipped in
two separate sections.
Shipping covers must be removed from the
ends where the sections will connect.
Lift and set the largest section first, checking
for the correct location and position.
In order to simplify the connection of the two
sections, it is important to position and set the
second section as close as possible to the first
section. This will allow the use of a come-
along tool, to pull the second section against
the first section. One come-along tool is
required on each side of the unit, connected
at the base slots. The two sections must be
tightly adjoined before the splicing parts can
be installed.
All parts required for splicing the sections
together are factory provided. Neoprene
gasket is provided to be applied on ends of
both sections.
Once the unit is completely assembled, it is
important to visually inspect all exposed
areas and fill any gaps with butyl caulking.
Splicing
1. Align base rail and side sections.
2. Check roof alignment and connecting
flange.
3. Fill post seam with butyl caulking. Apply
butyl caulking between roof flange
sections.
4. Attach splice plate to outside of post to
cover seam. Splice plate is typically
required on both sides of the unit.
5. Install factory provided roof splice cap
over the two sections connecting flange
and secure with screws along the length
of the cap.
6. Apply butyl caulking to all seams and
perimeter of splice and to the perimeter of
the roof splice cap against the roof of the
unit.

Attach splice cap with screws from
each side of the cap only. Do not
install screws from the top.
