INSTALLATION

This section describes how to install 39M units, compo-
nents, and component parts. Units specified on a single order
are shipped with most components assembled in the specified
airflow direction. When an upper component exceeds the 108-
in. maximum height limit, it is shipped out of its operating po-
sition. Some component parts also require assembly or adjust-
ment; see the section on each component type for specific in-
structions.
CAUTION
Failure to assemble the units according to the procedures
set forth below is considered improper installation and
abuse and may not only negatively impact the weathertight
performance of the unit, but may also negatively affect the
Carrier warranty.

NON-STACKED UNITS

1. The 39M split units will arrive at the jobsite in separate
pieces with section to section gasket installed. If the gas-
ket is damaged, obtain the required length of 0.25 in. x
1.50 in. closed cell gasketing locally (i.e., McMaster
8694K94 or Grainger 6YLW0).
2. Set upstream section on roof curb first for outdoor units
or on the pad for indoor units.
3. Remove shipping cover.
4. Set downstream section on roof curb or pad. Refer to unit
nameplate (Fig. 1) for sequence of section order. Down-
stream section must be set within
section for proper installation.
5. Pull baserails to contact bottom lifting lug connection. Do
not fully tighten. See Fig. 24, Detail C.
6. Align top brackets. Start the screw, but do not fully tight-
en. See Fig. 24, Detail A. For outdoor units, removal of
the roof at the split is necessary to access the top brackets.
7. On side of unit, when Intelliclamp connectors are present
(sizes 36 and larger only), align Intelliclamp connector,
start the screw, but do not fully tighten. See Fig. 24, De-
tail B.
8. (SIZES 17 AND LARGER ONLY) Remove the roof at
the split to access the top Intelliclamp connector(s), align
the Intelliclamp connector(s) and start the screw but do
not fully tighten.
9. Fully tighten all bolts starting from the base rails and
moving to the top. For outdoor units, reinstall all roof
sections. Section to section gasket should be compressed
to a thickness no larger than
caulk at shipping split joints from top of inside roof over-
hang to roof curb.
