Reassembling Split Units
Some RL Series units are built and shipped
in two separate sections.
Shipping covers should be removed from the
ends where the sections will connect.
Lifting and setting the largest section first is
recommended, 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.
