Installation—Mechanical
Location Considerations
Selecting the appropriate location for installing a unit is
very important. The following factors should be
considered:
1. Ceiling hung design must be of sufficient structure to
support the weight of the unit (see Tab l e 8 for weight
data). Figure 5, p. 13 through Figure 9, p. 17 show
hanging rod location and placement.
Note: Isolator and suspension rods are to be provided
by the installer. For hanging suspension, Trane
recommends 3/8-in. rods.
2. Service access is gained through the access panels on
the bottom of the unit. Sufficient space should be
allowed for panel removal. If the hinged panel option
is ordered, allow for a swing radius of 14-in.
3. Sufficient free area around both the discharge and wall
b
ox should be maintained to ensure proper
ventilation. If any part of the discharge is blocked off,
unit performance may be affected. If the wall box is too
small on the inlet, water or debris could be pulled into
the unit (see Tab l e 9) for minimum wall box free area
requirements).
4. Use the shortest and most efficient ductwork possible
when ducting the discharge and/or return air grille.
Units ordered with a duct collar discharge
arrangement are equipped with a 1-in. duct flange.
Note: Ductwork
for ducted units will be provided by
the installer.
5. If installing a split system, refe
r to the condenser
installation instructions provided with that unit for
special location considerations.
Note: M
easurements in Figure 5, p. 13 through
Figure 9, p. 17 do not include adjusted leveling
legs. Adjustment of Leveling legs should be
done first. New measurements from the floor
should be retaken before installation.
Unit Mounting
The horizontal unit ventilator may be attached directly to
the ceiling or suspended from the ceiling by hangers.
Hanger rods should be at least 3/8 in. diameter steel to
support unit weight, as given in Table 8, p. 21.
Install the hanging devices before hoisting the unit. A fork
lift or other special lifting device is required to hoist the
unit into mounting position.
Protect the unit finish by covering the lifting platform.
To hoist the unit into place, follow the instructions below:
1. Secure 2 x 4s to the lift forks. These two supports must
be long enough and spaced properly on the forks to
support the unit while it is being lifted and clear the
duct flanges on the unit.
2. Tip the unit onto the supports and slide it toward the lift
un
til the unit weight balances.
3. Lift the unit. Once in position, temporarily secure the
u
nit to the hanger rods or mounting studs with nuts
and washers.
4. Align the unit with the du
ct work. When in proper
alignment, tighten the mounting nuts securely.
5. Recheck the unit alignment and make sure the unit is
level
.
6. Replace all covers, panels and filters
before starting
the unit.
Note: Un
it must be mounted level. Coils and drain pans
inside unit are pitched properly for drainage before
shipment.
Horizontal Recessed Mounting
The recessing flange assembly ships in a box separate
from the unit. The assembly includes pre-cut flanges,
corner transition pieces, mounting screws, filler pieces,
and pressure sensitive gaskets. Refer to Figure 11 and
Figure 12, p. 22 for typical horizontal installation.

WARNING
Heavy Objects!
Always lift unit with fork trucks or other special lifting
device following the recommended procedures. Failure
to properly lift the unit as instructed, could result in
death or serious injury.
