Post and Rail Mounting
When mounting by post and rail, the structural support
should be run the full length of the unit. The structural
member should be located at the base of the unit as shown
in Figure 6 assuring the shaded area is well supported by the
structural member.
To assure proper system operation, it is important
that the unit is mounted level.
The post and rail setup should be done so that the unit
is level from side to side and over its entire length.
If resilient material is placed between the unit and the rail,
insert a heavy steel plate between the unit and the resilient
material to distribute the load. Cabinet penetrations (electri-
cal, piping, etc.) should be sealed in a professional manner
to protect against moisture and weather.

Rigging and Handling Instructions
Unit has either four or six lifting points (four-point shown below).
Caution: All lifting points must be used.
Note: Rigging cables must be at least as long as distance “A”.
Lift Only As Indicated
*Maximum recommended width for structural member is 5" (127 mm) to
allow for adequate space for duct connections and electrical entry.
Rigging and Handling
Lifting brackets with 2" (51 mm) diameter holes are provided
on the sides of the unit.
Use spreader bars, 96" to 100" (2438 to 2540 mm) wide
to prevent damage to the unit cabinet. Avoid twisting or
uneven lifting of the unit. The cable length from the bracket
to the hook should always be longer than the distance
between the outer lifting points.
If the unit must be stored at the construction site for an
intermediate period, set the unit in a reasonably level position
with adequate support.
Figure 7 shows an example of the rigging instruction label
shipped with each unit.
All lifting points must be used. Adjustment may be re-
quired for the middle cable in a 6-cable arrangement.

equal cable lengths may be re-
quired.
