Split Unit Assembly
Units may be split into modules for
shipping. Fan and coil modules must be
bolted together and factory provided splices
must be installed before operation of the
unit.
Split units will also require electrical
connection between the modules and
individual
units after assembly. See
Electrical Installation section and unit
specific wiring diagrams, within the unit
control compartment, for details.
Assembly
1. Remove all shipping covers prior to
assembly of modules.
2. Move the coil section to the required
location. See Figure 8.
3. For dual units (45-70 tons), move the
second coil section close to the first coil
section and align the bolt holes of the
coil sections. Compressor and control
service access doors of each section
should be on the same side of the
complete unit. A crow-bar or similar tool
can be used to line up the sections.
Factory provided bolts can then be used
to secure the coil sections together. See
Figure 9.
4. Align and set each fan section on top of
the coil section(s).
5. For dual units, align the bolt holes of the
fan sections, if they are shipped
separated. Fan service access doors of
each section should be on the same side
of the complete unit. A crow-bar or
similar tool can be used to line up the
sections. Factory provided bolts can then
be used to secure the fan sections
together. See Figure 9.
6. For dual units, install horizontal, vertical
and top splices, overlapping the fan and
coil sections. Fasten splices with self-
tapping #10 hex head screws. See Figure
9 and Figure 10. Single units (23-35
tons) do not require these splices. Only
corner slices are required for single
units.
7. Install corner splices, overlapping the
fan and coil sections. Fasten splices with
self-tapping #10 hex head screws. See
Figure 9 and Figure 10.
