Unit  
Information  
Single-Duct Units  
Figure 1 –Typical Single-Duct Units  
Dual-Duct Units  
The basic unit consists of a sheet metal  
casing with an air valve, which is used  
to modulate the air being delivered into  
the occupied zone.The unit is designed  
to modulate either cooling or heating  
air between the temperatures of 40°F  
and 140°F. Air enters the air valve  
through the round or rectangular inlet  
and exits into the sheet metal casing to  
be distributed to the zone either  
through integral round outlets in the  
casing or through rectangular duct  
attached to the discharge of the unit.  
The basic unit can also be ordered with  
factory-mounted electric or hot water  
heating coils attached to the discharge.  
(See Figure 1.)  
Dual-duct units provide two air valves:  
one as heating primary air and the  
other as cooling primary air. Both  
discharge into the common outlet,  
which leads to the zone being con-  
trolled. (See Figure 2.)  
The units are provided with a slip and  
drive rectangular duct connection or  
can be ordered with integral outlet  
plenum.  
Sequencing of the hot and cold air  
valve is dependent upon job  
requirements. One typical control is the  
valves working in conjunction with each  
other to respond to zone temperature.  
VCCF  
When the cooling valve becomes fully  
closed or reaches a specified minimum,  
then the heating valve will begin to  
modulate or vice versa.The typical  
result is that air flowing to the zone  
varies from the maximum down to a  
minimum and back up to a maximum  
as the load varies and as the controls  
would cause one air valve to close and  
the other to open.  
These re-heat units are used primarily  
to reheat air-to-zone temperature when  
the load in the occupied space is low.  
Primary air is modulated through the  
VariTrane air valve by rotating the  
damper blade. All air valves have a  
round/rectangular inlet for easy fit-up  
with incoming ductwork.  
Another typical application is when the  
unit provides a constant volume to the  
zone.When the zone sensor is tied  
directly to the heating valve, it will  
modulate the heating valve according  
to the zone temperature.  
VCWF  
When the heating valve is fully closed  
or there is a call for cooling in the zone,  
the cooling valve will be at constant  
supply. As the space becomes too cool,  
the heating valve will modulate open,  
decreasing the cooling valve flow.The  
typical result is that the air flowing into  
the zone stays at a constant flow  
VCEF  
whether the unit is heating or cooling.

Information  
Fan-Powered and Fan-Powered  
Low-Height Units  
VariTrane fan-powered and low-height  
fan-powered units can be either parallel  
or series, with or without re-heat. (See  
Figure 3.)  
VariTrane fan-powered unit fan sizes  
02SQ–05SQ and 08SQ–10SQ were  
performance tested at .12 in. w.g. and  
sizes 06SQ and 07SQ were tested at .15  
in. w.g. Units are not designed to  
operate unducted and below these  
tested static pressures.  
The fan on a series unit runs  
continuously whenever the main air  
handler unit is in operation.There are  
various options for starting the fan.The  
fan can be started three ways: 1)  
remotely, 2) by a duct pressure switch,  
or 3) by a combination of both.The  
particular fan control method may vary  
from unit to unit, depending upon job  
needs.  
Note: Fan-powered units are available  
with rectangular discharge connection  
only. The optional heater is mounted on  
the discharge of the unit. Hot water coils  
are connected to either the plenum inlet  
or on the discharge on parallel units, and  
to the discharge of series units.  
Figure 3 –Typical Fan-Powered Units  
Typically, the heater is off while the air  
valve modulates primary air and  
responds to zone temperature. If zone  
temperature decreases to the point  
where a decrease in primary air will not  
maintain the desired temperature, the  
re-heat will be activated to increase the  
temperature of the discharge air.  
On a parallel unit, theVariTrane air valve  
delivers primary cooling air to the unit  
outlet.When the space temperature  
decreases beyond air valve control, the  
fan is turned on as the first stage of  
heat.The fan delivers plenum air from  
above the occupied space to the unit  
outlet, which is mixed with primary air  
and delivered to the occupied space.  
VSCF  
VPCF  
Note: Either the fan, the air valve, or both  
can deliver airflow into the occupied  
space. In order to prevent primary airflow  
from exiting through the fan when the  
fan is not running on a parallel unit, a  
back draft damper is provided. When the  
fan is not running, the efficiency of this  
system is the same as a standard single-  
ductVAV unit.  
VSEF  
VPEF  
Typically, the control systems applied to  
parallel units cause the air valve to  
close to zero or a minimum flow before  
the fan is activated. After the fan is  
activated, the optional heat will be  
activated upon further reduction in  
zone temperature.Therefore, minimal  
primary air is mixed with the heated air.

Unit  
Installation  
Dual-Duct  
Due to their weight, theVAV terminal  
units should be suspended from the  
uppermost ceiling, independent of the  
false ceiling grid. Suspension devices  
are to be supplied by the installer. Units  
must be installed level and upright.  
Failure to level the unit properly may  
prevent proper operation of the  
controls and/or terminal unit. Units are  
not designed to be installed vertically.  
Consequently, this will also void the UL  
ratings and any warranty on the unit.  
Dual-duct units should be supported by  
either hanger straps or by using a  
threaded rod in conjunction with the  
hanger brackets that are provided on  
the unit. See Figure 5.  
Figure 5  
Dual-Duct Hanger Bracket Locations  
Single-Duct  
Depending upon the size and weight of  
the single-duct unit, it may be capable  
of being supported by the ductwork  
that is connected to it. No hanger  
brackets are provided on these units  
since the unit should be supported by  
means of a hanger strap.The hanger  
strap should be secured directly to the  
unit casing as shown in Figure 4.

Installation  
Duct Connections  
Care should be taken to properly  
support the water coil piping  
connections while connecting the  
adjoining pipe.  
Actuator Mounting  
AllVariTrane units should be provided  
with a minimum of 1.5-duct diameters  
of straight duct prior to the inlet of the  
unit. It is recommended that at least 48  
inches of straight duct be provided  
from the discharge of the units prior to  
any take-offs or transitions. This is a  
requirement for electric heat fan-  
powered units used in  
Trane offers a factory-mounted actuator  
with a 90-second drive time.The  
actuator drives 1 degree per second. A  
field-installed actuator may be used if  
desired.The actuator shaft has a ½-inch  
diameter and is designed to travel  
clockwise to close the damper and  
counter-clockwise to open the damper.  
There is an indicator on the end of the  
actuator shaft that can be used to  
determine the position of the damper.  
It is recommended that piping to the  
water coil should be done after field-  
mounted controls, external insulation,  
and ductwork connections have been  
completed.  
Do not connect water valve or pipe  
extensions to the water coil  
connections unless supported.  
applications with 100%  
downward discharge.  
Note: In order to maintain the UL rating  
forVariTrane electric coils, there must be  
four feet of straight unlined ductwork  
downstream of the reheat coil prior to  
any diffuser takeoffs.  
Unit Accessibility  
CAUTION  
Single-duct and dual-duct units  
Equipment Damage  
provided with hot water reheat have an  
access panel located on the side of the  
water coil. All other single-duct and  
dual-duct units are provided without  
access, as all functioning components  
are external to the unit.  
Note:When installing or replacing the  
actuator tighten the actuator set screw  
per the manufacturer’s instructions.  
Failure to follow the manufacturer’s  
specifications may result in unit  
malfunction.  
After all connections are made, check  
that the entire ductwork system is  
airtight. In some high-pressure  
Fan-powered terminals are provided  
with a sliding side access.  
systems, duct sealer may be necessary.  
Provide insulation around the entire  
inlet collar (all the way to the unit  
casing).  
Low-height terminal units have a  
removable bottom panel.  
Clearances  
Use caution not to damage the flow  
tubes when making ductwork  
connections or insulating.  
For proper service, it is recommended  
that at least 36” of side clearance be  
provided to service and access single-  
duct and dual-duct terminals units.  
Cut “slits” in the insulation for the flow  
tubes and secure with duct tape.  
Fan-poweredVAV units have a plenum  
inlet that must be clear of obstructions.  
Allow at least 36” of clearance in front  
of the side access and plenum opening.  
If the unit is to be installed in a location  
with high humidity, external insulation  
around the heating coil should be  
installed as required.  
Low-height fan-powered terminals  
require the same plenum clearance  
requirement that applies to the  
standard fan-powered units. However  
the access to the internal components  
is located on the bottom of the unit.  
Water Coil Connections  
Water coil piping connections will be  
3/8” or 7/8” OD.  
If necessary, you can change the coil  
connection from left-handed to right-  
handed (and vice-versa) by  
disconnecting the coil from the unit  
and rotating the coil “like a steering  
wheel” 180°.  
It is also recommended that 6” of  
clearance be provided to the top and  
bottom of all the units.  
Note:The minimum clearance for  
The inlet piping should always be  
connected to the bottom connection of  
the coil regardless of handedness.  
controls and heater controls should be  
36” for all models except units with 575-  
volt electric heaters, which require 48” of  
clearance. NEC and/or local codes  
override all clearance requirements.

(SCR) Motor Speed Control  
Adjustment Procedure.  
Figure 17 – Internal Potentiometer  
Electrically Commutated Motor (ECM)  
Trane offers an energy efficient ECM  
motor as a motor option. Balancing of  
an ECM motor is accomplished  
through electronic control adjustments  
on the ECM control board (see Figure  
15). Potentiometer settings for a  
multitude of CFM settings are given in  
Charts 4–15. Other potentiometer  
settings can be determined either by  
interpolating from these tables or by  
using the following equation:  
In order to make units more convenient  
and efficient to balance, an SCR  
(silicone control rectifier) is provided as  
standard on all fan-powered units.  
Max  
120 v  
The SCR is located on the side of the  
fan control box. To adjust the speed of  
the motor, the external knob must be  
rotated either clockwise or  
counterclockwise depending on the  
desired speed adjustment.  
208 v–  
277 v  
347 v  
CFMsetting = CFMmin +  
{(Potentiometer Setting) x [(CFMmax -  
CFMmin)/100]}  
There is an internal potentiometer  
(Figure 14) setting on the SCR controller  
that can be accessed by removing the  
control box cover. This internal  
potentiometer is set at the factory to the  
specific motor voltage.  
It may be necessary to adjust this in the  
field depending on the building’s power  
factor.  
DO NOT SET THIS  
POTENTIOMETER  
BELOW THE VOLTAGE  
OF THE FAN MOTOR.  
There is an LED on the ECM control  
board, which will blink one time for  
every 100 CFM of motor setting. For  
example, the LED on a unit set for 790  
CFM will blink 7 times. The LED on a  
unit set for 800 CFM will blink 8 times.  
NOTE: Do not set this potentiometer  
below the voltage of the fan motor.  
NOTE:This feature only verifies that the  
CFM is set properly. This feature does  
not indicate at what speed the motor is  
actually running.  
WARNING  
HazardousVoltage!  
Disconnect all electric power, including  
remote disconnects before servicing.  
Follow proper lockout/tagout proce-  
dures to ensure the power cannot be  
inadvertently energized. Failure to  
disconnect power before servicing  
could result in death or serious injury.  
The ECM must be “load tested.” In other  
words, the fan must be connected to  
properly test the ECM.

Maintenance  
Figure 27 – Standard Motor Removal  
Figure 28 – Low-Height Motor Removal  
Periodic maintenance of theVariTrane  
product is minimal, but necessary for  
efficient operation. Routine mainte-  
nance consists of inspecting/replacing  
the air filters of the fan-powered  
terminals.  
Motors  
Both the PSC (permanent split capaci-  
tor) and the ECM (Electrically Commu-  
tated Motor) require no lubrication  
during its normal life of operation.  
FanWheel:  
Periodically, the fan wheel should be  
inspected for dirt or debris and cleaned  
as necessary.  
Standard height fan-powered series  
and parallel fan motors are replaceable  
through the filter opening and the  
standard sliding side access panel. To  
access the fan motor, the fan housing  
must be detached by removing the  
mounting bolts that hold the housing to  
the fan board. Removing the entire  
housing allows the fan motor, fan  
housing, and fan wheel to be re-aligned  
on a workbench or floor and prevent  
any possible fan wheel rubbing that  
may occur. Removing the housing will  
provide access to the motor shaft set  
screw that holds the fan wheel to the  
motor shaft.  
The low-height fan assembly was  
designed with an inlet ring that assists  
with removal of the fan motor. To  
access the fan motor assembly, the  
bottom panel must be removed. The  
inlet ring is held in place by six bolts  
and three motor mount bolts. Remove  
these bolts and the motor and fan  
wheel will come out of the fan housing.  
Filter  
The filter on fan-powered terminals will  
need to be inspected/replaced routinely  
depending on the environmental  
conditions of the plenum.  
Water Coil  
Water coils should be inspected and the  
fins should be cleaned periodically.  
Water coils have been provided with an  
access panel as standard to assist with  
inspection and cleaning.  
Fan Motor Replacement  
WARNING  
HazardousVoltage  
w/Capacitors!  
Disconnect all electric power, including  
remote disconnects and discharge all  
motor start/run capacitors before  
servicing. Follow proper lockout/tagout  
procedures to ensure the power cannot  
be inadvertently energized.Verify with  
an appropriate voltmeter that all  
capacitors have discharged. Failure to  
disconnect power and discharge  
capacitors before servicing could result  
in death or serious injury.  
WARNING  
Rotating Components!  
Disconnect all electric power, including  
remote disconnects before servicing.  
Follow proper lockout/tagout proce-  
dures to ensure the power cannot be  
inadvertently energized. Failure to  
disconnect power before servicing  
could result in death or serious injury.

Drywall/Plaster Ceiling  
All units must be installed upright and  
level as indicated by the arrow on the  
side of the units. Return air slots should  
be placed perpendicular and offset to  
the slot diffusers to avoid short-  
Finish installation of diffusers in plaster

completing the ceiling construction  
(Figure 31).  
1. Suspend the units above the intended  
ceiling level and their approximate  
horizontal positions and finish running

circuiting of air distribution patterns.  
Place the unit in its approximate final  
position and check that it is upright and  
level. For single- slot units, engage  
the back of the diffuser over the t-bar  
with an edge and both ends resting on  
the t-bar. For double-slot units, slide  
the unit over the t-bar. For center-  
notch units, place diffuser over the  
t-bar, straddling it across a t-bar and  
resting on the units ends.  
2.After drywall and/or plaster is installed,  
cut openings to receive the diffuser air  
outlets. Also, allow for access openings  
to complete installation and service of  
the unit.  
3.Slide the trim accessory up and into the  
ceiling opening. Using the rim  
accessory as a template, drill four guide  
holes in the lip of the diffuser slot.  
Lower the unit onto the trim frame and  
attach with the sheet metal screws.  
Concealed Spline Ceiling  
Follow these procedures to finish  
installation of control and satellite  
diffusers and concealed spline for  
suspension ceilings before completing  
the ceiling construction (Figure 30).  
Place the units in their approximate  
final positions. If using the trim angle  
diffuser, its slots must be even with the  
spline level. If applying the trim  
If the unit has a fire damper, make sure  
that the damper is still fully open.  
Diffuser discharge must always be  
flush with the ceiling tiles to assure the  
proper airflow (Coanda effect).  
Note:The bottom of the throat section  
must be parallel to the ceilings for proper  
air distribution.  
Diffusers require specific installation  
information when mounting to a  
desired ceiling type. Select the ceiling  
type that closely matches the job site  
application and use the following  
procedures.  
CAUTION  
accessory, the bottom of the diffuser  
must be level with the finished ceiling.  
Equipment Damage!  
Do not install trim frame into ceiling  
using screws.When diffuser is placed  
on the trim frames, it will pull out.  
If installing the trim accessory, insert  
the trim into the ceiling opening from  
below and engage the diffuser slot to  
the trim t-bar structure.With bottom  
flange of trim accessory against the  
ceiling, and using the pre-drilled holes  
in the flange as a guide, drill holes in the  
flange of the diffuser. Join the diffuser  
and trim accessory with self-taping  
sheet metal.  
T-Bar Ceiling  
Finish installation of the diffuser in t-bar  
ceiling. (See Figure 29.) Follow these  
procedures before the ceiling construc-  
tion is completed.  
1.Position the diffuser at each end resting  
directly on the structural t-bar for  
support and the t-bar fitting into the  
channel provided at the unit discharge  
air throw.
