Configuration
The classroom unit ventilator is configured in both a:
• horizontal (ceiling mount)
• vertical (floor mount)
configuration. The units range from 750
cfm to 2000 cfm for the horizontal configuration, and from 750 cfm to 1500
cfm for the vertical configuration.
Cabinet
The units are constructed of 14- and 16gauge zinc coated steel. All steel surfaces are cleaned, phosphatized, rinsed
and dried before application of final finish paint. The paint is applied by an
electrostatic powder spray system, minimum thickness of 1.5 mil which results
in an appliance grade finish.
Front Panels
The front panels are retained by Allen
wrench operated locks which open with
a 180-degree rotation. The vertical front
panel is constructed of either 14 or 16
gauge material dependent upon model
option selected.
End Pockets
Unit Ventilators are equipped with end
pockets to provide field installation of
valves, piping, and controls. The units
have a large pipe access opening in
both end pockets and large knockouts
for piping and electrical connections.
All electrical connections are made in
the left-hand end pocket, with exception
of units equipped with the electric heating coil option.
Drain Pan
The drain pan is positively sloped in all
planes to assure proper drainage and
help eliminate the risk of microbial
growth. To help ensure indoor air quality, the drain pan is insulated on the bottom to help prevent condensate formation. The drain pan can be easily
removed for cleaning purposes. A drain
plug is located on each end of the drain
pan on the vertical unit. The drain pan
is drilled-out and pitched toward the
cooling coil connection during assembly per model number selection.
Fanboard
The fanboard assembly is acoustically
designed in a single, rigid assembly
that includes the fans, fan housing,
bearings, fan shaft and motor. The fan
motor is mounted on the fanboard. The
fanboard is made from 14 gauge galvanized steel to resist corrosion and
increase strength.
115V Motor
The motor is a single speed permanent
split capacitor with thermal overload
protection. A multiple tap auto-transformer is wired to the motor to provide
different speed settings. The motor
speed is not affected by damper positions. Standard motors are rated up to
0.25 ESP. High static motors are rated
from 0.25 ESP to 0.45 ESP.
Motor bearings are permanently lubricated. Isolation of the motor is provided
internally at the union shaft.
Sampling Chamber (Option)
A sampling chamber is provided for
housing the room air sensor whenever
a unit mounted sensor is specified for
Tracer ZN520 controls (Figure 1). The
sampling chamber is placed below the
air-coil where room air is continuously
drawn into the chamber before being
tempered by the coil. This ensures an
accurate response to temperature
changes in the room.
Filter
Standard units are equipped with a single 1-inch thick filter that is accessible
without removal of the unit front panel.
Filter options include throw-away and
permanent renewable.
Dynamic air barrier units contain two
filters (1-standard/1-return air). The
return air filter requires front panel
removal for filter access.
OA/RA Damper
Trane unit ventilators are equipped with
dual blade type mixing damper to
ensure proper modulation and mixing
of return and outdoor air designed in
accordance to ARI 840. A splitter is
placed between the damper blades to
separate the fresh-air and return-air
compartments to prevent draft blowthrough.
An ultra low-leak damper seal is
applied on all vertical unit configurations. The seal consist of a medium
density, closed-cell neoprene material.
The seal is fixed and not part of the
damper assembly. The outside-air
damper closes into the closed cell neoprene material, providing a positive
pressure seal.
Figure 1: Sampling Chamber
General Information
UV-SVN002-EN 5
OA/RA Actuator (Option)
The OA/RA actuator provides true
spring return operation for positive
close-off of the OA/RA damper. The
spring return system of the actuator
closes the outside damper if power is
lost to the building. When ordered with
factory mounted controls, the actuator
is 3-point floating. A 2 to 10 VDC actuator is also available when other than
Trane controls is required. See Table 1
for technical data of the OA/RA actuator.
Face and Bypass (Option)
The face and bypass option consist of
an actuator, damper blade and 2-position water valve (option).
During bypass mode, the damper
moves to prevent air from traveling
through the coil. The damper blade is
tightly sealed to eliminate heat pickup
while in the full bypass mode.
A two-position isolation valve control
(option) further enhances this system
by closing off all water flow to the coil
during full bypass operation. 2-pipe
main steam systems utilize the face and
bypass as part of the standard operation and may incorporate the optional
isolation valve.
Face and Bypass Actuator
(option)
The face and bypass damper actuator
incorporates a direct couple design for
both the horizontal and the vertical configurations. The actuator is provided
with electronic protection against overload. It does not contain, nor require a
limit switch. When reaching the damper
end position, the actuator automatically
stops. The gears can be manually disengaged with a button on the actuator
housing.
See Table 2 for technical data.

Modulating Water Valves (Option)
The modulating control valve option
provides optimum control of hot and
chilled water flow in various heating
and cooling applications. They are
designed to provide sinusoidal valve
actuator travel and operate silently,
resisting water hammer.
The actuator on the valve is a 24V, 3point floating type. See Table 3 for more
technical data.
Isolation Valves (Option)
The isolation valves are two position
24V, spring return type. They provide
added control in heating and cooling
applications when used in conjunction
with the face and bypass damper.
On heating coils and two-pipe changeover applications, the valve is a normally open type to prevent the coil from
freezing in case of power loss.
For cooling, the valve is normally
closed and opens when there is a call
for cooling. See Table 4, for more technical data.

Unit Ventilator Controls
Controls are provided either by Trane as
a factory-mounted option or furnished
by an outside vendor and mounted at
the job-site.
Units constructed for field installation
of controls are shipped with one of the
following type of controls:
•
No Controls/Field Installation:
(Option) The unit comes equipped
with an auto transformer, fan speed
switch and damper blade only.
•
End Device Package (EDP)
:
This option pre-wires optional
control components to a terminal
strip for wiring field provided
controller and temperature sensor.
NOTE: For controller operation malfunction of any non-Trane, fieldinstalled controls, consult the literature
or technical support of the controls
manufacturer.
Trane offers Direct Digital Controls for
the unit ventilator. The ZN520 (See
Figure 2) unit controller is designed to
provide control of the classroom unit
ventilator and the fan coil products and
adds increased functionality to the unit
ventilator.
When Trane controls are ordered for an
installation, the controls are shipped
already installed and factory-tested to
ensure proper operation at start-up.
NOTE: For more details on the ZN520
unit controller option or operation and
service/replacement issues, please refer
to
CNT-SVX04A-EN:
Tracer ZN520 Unit
Controller IOP.
Automatic Controls
Regardless of type of controls, all systems provide a sequence of operation
designed to provide rapid warm-up of
the room and increase ventilation while
offsetting overheating.
In addition, air conditioning installations will usually provide a means of
system changeover from heating to
cooling as well as provisions for drawing a pre-determined amount of outside
air into the room.
Unit Switch
The unit “On-Off” switch, provided by
Trane, is typically housed in the control
box mounted in the left hand end pocket immediately below the discharge
grille.
When Trane ZN520 unit controllers are
used, the unit switch is located on the
switch module in the end pocket behind
the front panel rather than below the
grille.

Receiving and Handling
8 UV-SVN002-EN
The unit ventilator is packaged in clear
stretch wrap and protective to allow for
immediate visual inspection. Vertical
units are also shipped with a protective
cardboard cover to help prevent
scratching and other cosmetic blemishes during transport (Figure 3).
Horizontal units are shipped with cardboard blocking on all edges for protection during shipping (Figure 4).
NOTE:
Before unwrapping, make a
visual inspection of the unit for any
damage that may have occurred during
shipping. All orders are shipped FOB
(Free on Board) from the factory, therefore any claims must be made with the
delivering carrier.
Following visual inspection, carefully
begin the following procedures:
1. Carefully remove the stretch
wrap and the top cardboard
cover.
If end covers have been
ordered for vertical units, the
panel will already be mounted to
the unit.
2. Remove remaining cardboard
blocking
3. Remove the front (vertical) or
bottom (horizontal) access
panel with a 7/32” Allen wrench.
4. Verify nameplate sales order
number is correct.
5. Remove shipping bracket from
the lower rear corners of the unit
and shipping skid. Access to the
screws holding unit to the skid is
obtained inside the unit.
6. Rotate fan wheels manually.
Wheels should move freely and
be in proper alignment. Visually
inspect the fan area for obstru-
tions or shipping damage.
7. Remove all applicable knockouts for coil piping and
electrical connections.
