Installation
Location Considerations
Selecting the appropriate location for
installing a unit is very important. The
following factors should be considered:
Vertical Unit Ventilators
1. Floor design must have sufficient
structure to withstand the weight
of the unit while allowing for
openings in the floor for a Return
Air duct, electrical and piping
supply lines fed through the
floor. See Figures 6-10 for unit
dimensions and Table 5 for unit
weights.
2. Wall space design should allow
the unit to be mounted to the
wall securely. The wall surface
behind the unit should be
smooth and level. A wall slightly
out of level may cause problems
with unconditioned air
leaking into the room. Remove
any object projecting more then
1/8” (.3175cm) from the wall sur-
face.
NOTE: Additional gasketing
may be installed to accommo-
date for uneven wall.
3. There are two removable knock-
outs in the rear of the unit, on
either end, for piping and
electrical supply lines. A pipe
chase is located in the upper
back portion of the unit for
crossover piping
(See Figures 6-
10). The Fresh Air opening is
located in the lower back of the
unit and the path to the wallbox
on the outside wall should be
unobstructed.
4. The physical layout of the room
should accommodate any acces-
sories ordered with the unit.
Conditioned air is distributed
through the grille on top of the
unit and returned through the
return air grille on the bottom of
the unit. Avoid placing any
objects that may obstruct either
grille or interfere with airflow.
5. Internal access to the unit is
provided by the removable front
panel. Sufficient space should be
allowed to lift the panel for
maintenance purposes.
6. Make sure the unit is placed on a
level surface. The unit leveling
legs can also be adjusted to
accommodate slight out-of-level
installation surfaces.
Horizontal Unit Ventilators
7. Ceiling hung design must be of
sufficient structure to support the
weight of the unit.
See Table 5 for
weight data. Figures 11-14 show
hanging rod location and placement.
NOTE: Isolator and suspension
rods are to be provided by the
installer. Trane recommends 3/8”
rods for hanging suspension.
8. 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”.
Vertical and Horizontal Units
9. Sufficient free area around both
the discharge and wall box
should be maintained to ensure
proper ventilation. If any part of
the discharge is blocked off, unit
performance may be effected. If
the wall box is too small on the
inlet, water or debris could be
pulled into the unit. See Table 6
for minimum wall box free area
requirements.
10. 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” duct flange.
NOTE: Ductwork
for ducted units will be provided
by the installer.
11. If installing a split system, refer
to the condenser installation
instructions provided with that
unit for special location consider-
ations.
NOTE: Measurements in Figures
6-10 do not include adjusted
leveling legs. Adjustment of
Leveling legs should be done first.
New measurements from the
floor should be retaken before
installation.
