Re eiving Inspe tion
After unpacking the assem ly check it for
shipping damage. If any shipping damage is
found, report it immediately to the delivering
carrier. During unpacking and installation do
not handle y the inlet velocity sensor or the
control package.
Determine Position of the
Control En losure
The control enclosure can e installed on
either side of the ductwork y flipping the VAV
unit over 180 degrees. Unit with mercury
contactors, pneumatic controls, and digital
controls (DDC) need to e inspected efore
installing.
Important: Unit with mercury contactors is
position sensitive. As a result, efore installing
unit with mercury contactors, inspect the
position of the mercury contactors in the
control enclosure. Mercury contactors must e
heading up 90 degrees vertically. If they are
heading down, unscrew the mercury contactors,
rotate 180 degrees, and reinstall them.
If unit is equipped with pneumatic controls, it
should e mounted right side up and level
within ±10 degrees of horizontal, and parallel to
the airflow. The first letter in the model num er
indicates control type (P is for pneumatic). If
the unit is mounted upside down, the controller
will have to e repositioned, re-piped, and
recali rated. Analog control units (A-analog
model num er pre-fix) may e installed in any
orientation. Some Digital (DDC) controls
(D-digital model num er pre-fix) are position
sensitive dependent on the airflow sensor
transducer. Check with the controls
manufacturer for verification.
Supporting the Assembly
We recommend that each terminal unit e
independently supported, especially when
accessory modules, such as coils, attenuators,
silencers or multiple outlets are present.
Hanger straps may e used and screwed
directly into the sides or ottom of the unit
casing (see Fig. 1). Alternately, a carriage
made of unistrut may e used, somtimes this is
known as a trapeze setup. Support the VAV
and any accessories separately (Fig. 2). When
requested, unit is supplied with field mounted
hanger rackets for use with hanger rod up to
3/8" (9.5) dia. Hanger rackets should e
screwed into the top of the unit casing (see Fig.
3 & 4). Use the support method prescri ed for
the rectangular duct in the jo specifications.

Single duct terminals units are shipped from the factory with the following information labels.
1) Sample Nameplate Label
– affixed to the air terminal casing beside the control mounting panel. Shows tagging information, serial-model number, size, cfm, voltage,
amps, MOP, etc.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection as described in the job specification. The
diameter of the inlet duct for round inlets (unit size 4 through 10)
must be equal to the listed size of the terminal. The inlet collar of
the terminal is made 1/8" (3) smaller than listed size in order to fit
inside the duct (see figure 1). Unit size 12 through 16 utilize flat
oval inlet collars and unit size 24 x 16 has a rectangular inlet collar.
The flat oval inlets are undersized for flexible duct connection. For
hard inlet duct connections, refer to submittal drawing for
dimensional data. On exhaust units the duct should mate to the
terminal using slip and drive connections (see Fig. 4).
Important: Do not insert ductwork inside the inlet collar of the
assembly. For optimum performance, 2 to 3 equivalent diameters of
straight duct should be installed prior to the inlet of the unit. All
ducts should be installed in accordance with SMACNA guidelines.
The outlet end of the terminal is designed for use with slip and drive
duct connections. A rectangular duct the size of the terminal outlet
should be attached.
Field Wirin
All field wiring must comply with NEC and local codes. Electrical,
control, and piping diagrams can be found on labels affixed to the
exterior/interior of the control enclosure box. All Nailor electric
heaters are staged per specifications. The installing electrician
should rotate the incoming electric service by phase to help
balance the building electric load.
IMPORTANT: Electric re-heat units ordered with SC or
SS , route field wiring near bottom of control box. Do not
place directly behind SC or SS .
Fuse size designates the size of the internal fuse if it is supplied.
Maximum Overcurrent Protection (MOP) designates the largest
breaker or fuse in the electrical service panel that can be used to
protect the unit.

Recommended Maintenance
Single Duct Terminal Units supplied with stainless steel
construction are supplied with Celcon®bearings as standard.
Bronze oil impregnated bearings and 316 stainless steel
bearings are optional for certain applications. It is
recommended that those units equipped with 316 stainless steel
bearings be lubricated periodically as required by the application
and environment.
A Silicone based lubricant such as DuPont™ Pure Silicone
Lubricant with KRYT X®PTFE or equivalent should be applied
to the shaft between the shaft and the bearing surface to
prevent excessive wear. This can be done without removal of
the shaft by pushing or pulling the shaft in one direction while
using a spray applicator tube to inject lubricant into the small
gap formed on the opposite side.

Page 1 of 4
Receiving Inspection
After unpacking the assembly check it for shipping damage. If any
shipping damage is found, report it immediately to the delivering
carrier. During unpacking and installation do not handle by the inlet
velocity sensor or the control package.
Supporting the Assembly
Dual duct units are designed to be independently supported. When
requested, unit is supplied with field mounted hanger brackets for
use with hanger rod up to 3/8" (9.5) dia. Hanger brackets should be
screwed into the top of the unit casing sides and/or the inlet and
outlet ends. Hanger straps may alternately be used and screwed
directly into the sides of the unit casing. Use the support method
prescribed for the rectangular duct in the job specifications.
Important: If unit is equipped with pneumatic controls, it should be
mounted right side up and level within ±10 degrees of horizontal
and parallel to the airflow. The terminal is marked with a label
stating "Top of Unit".The first letter in the model number indicates
control type (P is for pneumatic). If the unit is mounted upside
down, the controllers will have to be re-positioned, re-piped, and re-
calibrated. Analog control units (A-analog model number pre-fix)
may be installed in any orientation. Some Digital (DDC) controls (D-
digital model number pre-fix) are position sensitive dependent on
the airflow sensor transducer. Check with the controls manufacturer
for verification.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection as described in the job specification. The
diameter of the inlet duct "D" (see Figure 1) for round inlets (Models
3230 and 3240 with mixing attenuators) must be equal to the listed
size of the terminal; i.e., a duct that actually measures 8" (203)
must be fitted to a size 8 terminal inlet. The inlet collar is made 1/8"
(3) smaller than nominal duct size in order to fit inside the duct.
Model 3210 (no mixing attenuator) utilizes flat oval inlet collars on
unit sizes 12 through 16. They are undersized for flexible duct
connection. For hard inlet duct connections, refer to submittal
drawing for dimensional data. The supply ductwork should be
insulated up to the face of the terminal unit.
Important: Do not insert duct work inside the inlet collar of the
assembly. For optimum performance, 2 to 3 equivalent diameter
of straight duct should be installed prior to the inlet of the unit. All
ducts should be installed in accordance with SMACNA guidelines.
The outlet end of the terminal for models 3230 and 3240 is supplied
with a rectangular collar. A rectangular duct the size of the terminal
outlet should be attached.
Model 3210 is supplied with slip and drive duct connections. A

Re eiving Inspe tion
After unpacking the assembly check it for shipping damage. If
any shipping damage is found, report it immediately to the
delivering carrier. During unpacking and installation do not
handle by the inlet velocity sensor or the optional control
package.
Installation
For installation, cut a rectangular opening in the side of the duct.
The opening should be the height of the duct and 12" (305) wide
as shown in Figure 1. If the duct has internal insulation, cut a 1
inch wide strip of insulation inside the duct. The strip of
insulation removed will allow the assembly to slide in smoothly.
Make sure the inlet airflow sensor is installed upstream of the
damper and in direction of airflow. Use sheet metal screws
along the left and right side of the mounting plate as well as the
top and bottom flanges in order to secure the mounting plate to
the rectangular duct. eal as necessary in order to meet
applicable standards. Any control components can now be
installed and connected.

Receiving Inspection
After unpacking the assembly; check it for shipping damage. If any
shipping damage is found, report it immediately to the delivering
carrier. During unpacking and installation do not handle by the
control package.
Supporting the Assembly
Although the basic unit is light enough that it can be supported by
the ductwork itself, we recommend that it be independently
supported, especially when accessory modules, such as coils,
attenuators, or multiple outlets are present. When requested, unit is
supplied with field mounted hanger brackets for use with hanger
rod up to 3/8 (9.5) dia. Hanger brackets should be screwed into the
top of the unit casing. Hanger straps may alternately be used and
screwed directly into the sides or bottom of the unit casing. Use the
support method prescribed for the rectangular duct in the job
specifications.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection as described in the job specification. The
diameter of the inlet duct for round inlets (unit size 4 through 10)
must be equal to the listed size of the terminal. The inlet collar of
the terminal is made 1/8 (3) smaller than listed size in order to fit
inside the duct. Unit size 12 through 16 utilize flat oval inlet collars.
The flat oval inlets are undersized for flexible duct connection. For
hard inlet duct connections, refer to submittal drawing for
dimensional data.
Important: Do not insert ductwork inside the inlet collar of the
assembly. For optimum performance, 2 to 3 equivalent diameters
of straight duct should be installed prior to the inlet of the unit. All

exterior/interior of the control enclosure box. All Nailor electric
heaters are staged per specifications. The installing electrician
should rotate the incoming electric service by phase to help
balance the building electric load.
Fuse size designates the size of the internal fuse if it is supplied.
Maximum Overcurrent Protection (MOP) designates the largest
breaker or fuse in the electrical service panel that can be used to
protect the unit.
Control Start-up, Operation
Your local Nailor Representative can provide detailed information
about start-up and operating procedures for Nailor’s digital, analog,
and pneumatic controls. For specific information on controls
provided by other manufacturers, contact the specific
manufacturer’s local or national office. This applies whether the
controls were factory or field mounted.
Note: Digital controllers may use specific communication
addresses based on Building Management Systems Architecture
and original engineering drawings. Installing the terminal in a
location other than that noted on the label may result in excessive
start-up labor.
Balancing Procedure
This balancing procedure assumes that the fan supplying the
system maintains a constant static pressure in the supply duct to
the terminal unit. Bypass terminal units are pressure dependent and
will need rebalancing if system duct static pressure changes.
The 3400 series are shipped with both inlet and bypass balancing
dampers as standard to permit ease of field balancing and to ensure
accurate adjustment and optimum operation.
1. Fully open the dampers of all supply outlets on the discharge
duct from the terminal unit.
2. Place terminal in the full open position, supplying 100% air to the
occupied space by adjusting the thermostat to full cooling.
3. Adjust the balancing dampers located in the terminal inlet to
provide the required total airflow.
4. Starting with the outlet furthest downstream, adjust the damper
of each air outlet to the required air volume.
5. Take a static pressure reading at the terminal unit, using a
magnehelic gauge or equivalent.
6. Adjust the room thermostat to full heating to provide 100%
bypass airflow or the minimum air volume to the room, if a
mechanical minimum air volume stop is utilized. An indicator mark
on the end of the driveshaft shows damper position, 90° rotation
CW to close.
7. Adjust the bypass outlet damper(s) on the terminal until the static
pressure reading equals that obtained in step 5.
8. Re-adjust the room thermostat to the desired setpoint
temperature. The terminal is now balanced.
Dimensions are in inches (mm).

with a lock nut (field supplied by
user). Length of screw is
unimportant as long as it has adequate thread length. Damper
rotates 90°, CW to close and has built in end stops.
1. Direct acting/normally closed damper connection: Disconnect
control air to actuator. Ensure damper and actuator are in
alignment. Damper should be fully closed.
(a) Using mechanical minimum stop. Adjust screw to back-off
damper to required minimum airflow position.
(b) Using damper end stops (no mech. minimum stop provided).
Loosen collar set and bushing on damper shaft. Rotate damper
shaft CCW to desired minimum airflow position and re-tighten
actuator connection.
2. Reverse acting/normally open damper connection:
(a) Using stroke stop screw. Apply 20 psi main air to actuator.
Insert screw (by others) and back-off damper to required minimum
airflow position.
(b) Using damper end stops (no built-in stroke stop screw). Loosen
damper/actuator collar set and bushing coupling. Apply 20 psi main
air to actuator. When actuator reaches the end of its rotation, rotate
damper shaft CCW to desired minimum airflow position and re-
tighten on shaft.
Electric Actuators
KMC MEP-5071 (standard). Position damper to the full open
position. Depress the gear disengagement button and position the
drive collar so the indicator mark is at the "90" mark. Tighten
setscrews on shaft. Loosen lower travel stop one-half turn and slide
to desired position. Tighten stop screw.
Honeywell ML6161B-2024 (optional). Use clutch to position damper
in fully open position. Insert setscrew with lock nut (supplied) in the
threaded hole in top left corner of actuator, turning CW until fully
inserted. With setscrew fully inserted, minimum position is 30°, fully
out O°. Use conversion of approx. 1.7 angular degrees per turn of
the setscrew. Back screw out of housing and stop slightly short of
the calculated position. This allows the setscrew to be set
accurately while taking airflow measurements. (Important: Do not
back-drive actuator with setscrew, damage may result.) Rotate
actuators to minimum position using the manual declutch.
Accurately set minimum flow by backing-off setscrew as required
using airflow measurement. Using locknut, secure against actuator
housing to lock setscrew in place.

Receiving Inspection
After unpacking the terminal unit, check it for shipping damage. If
any shipping damage is found, report it immediately to the
delivering carrier. Store units in a clean, dry location.
Caution: Do not use the inlet collar, damper shaft, airflow
sensor, electrical conduit, or tubing as a handle to lift or move
assembly. Damage to the air terminal unit or controls may
result.
Supporting the Assembly
Suspend the unit from the building structure in a horizontal plane.
Be careful not to obstruct all the access panels with support
channels or straps. When requested, unit is supplied with field
mounted hanger brackets for use with hanger rod up to 3/8" (9.5)
dia. Hanger brackets or straps should be screwed to the top corner
posts, unit casing sides or alternatively onto the inlet and outlet
ends of the unit if the top corner posts are not accessible. Fan
powered VAV terminal units are too heavy to suspend with the
ductwork. They must be independently supported.
Nailor recommends attaching straps or screws into the 16 gauge
frame of the 35S and 35P Series units for mounting when possible
as shown in the figures below.
Duct Connections
Slip each inlet duct over the inlet collar of the terminal. Fasten and
seal the connection by the method prescribed in the job
specification. The diameter of the inlet duct in inches must be equal
to the nominal size of the terminal inlet. The inlet collar of the
terminal is 1/8" (3) smaller than the nominal duct size to allow it to
fit inside the duct. Important: Do not insert ductwork inside the
inlet collar of the assembly. For optimum performance, 2 to 3
equivalent diameters of straight duct should be installed prior to the
inlet of the unit. All ducts should be installed in accordance with
SMACNA guidelines. Rectangular discharge opening is designed
for a flanged duct connection. A clear area around the opening has
been left for screw penetration. Fasten and seal all connections by
method prescribed in the job specification.
Minimum Access
Make appropriate accommodations for access panel removal.
Nailor 35S and 35P fan powered VAV terminal units have access
panels on the top, bottom and sides. Nailor 35N units have only
bottom panels. Model 37S has top and bottom panels. Model 38S
has only top panels (or bottom panel if the 38S 1 is oriented for
ceiling use). For low voltage control enclosure access, a minimum
of 18" (457) is recommended. Specific control enclosure location is
indicated on product submittals. Low voltage control enclosures
have removable covers that are attached with sheet metal screws.
High voltage controls enclosures have access panels that are
equipped with hinges. For clearances for full opening of hinged
access doors, refer to project specifications, submittal sheets and
NEC.
Important: These recommendations do not preclude NEC or
local codes that may be in effect, which are the responsibility
of the installing contractor.

Field Wiring
All field wiring must comply with NEC and local codes. Disconnect
switches are optional. Also, electrical, control, and piping diagrams
can be found on labels affixed to the exterior/interior of the control
enclosure box. Unless specifically requested by customer, all units
are wired for a single point connection to the fan and electric heater
(if present). All electric heaters will be staged per specification.
Motors rated for 277 or 120VAC on units with 480 or 208VAC
ratings respectively are always connected between the neutral and
L1 terminals. The installing electrician should rotate the incoming
electric service by phase to help balance the building electric load.
Fuse size designates the size of the internal fuse if it is supplied.
Maximum Overcurrent Protection (MOP) designates the largest
breaker or fuse in the electrical service panel that can be used to
protect the unit.
ELECTRICAL SUGGESTIONS AND REQUIREMENTS:
1. Provide a safety disconnect per NEC 424-19, 20, 21
2. Disconnect the power supply before wiring or servicing unit.
If a disconnect switch is present, it should be in the OFF
position while making power connections or repairs.
3. All units with electric heat should have copper wires sized
for 125% of Nameplate Amperage.
4. Follow wiring diagrams and instructions mounted on the
unit. 480V/3 phase heaters, for example, require a neutral
wire in addition to the full sized ground wire. NEC 424-15
and 250 also require that all units be grounded.
Control Start-up and Operation
Your local Nailor Representative can provide detailed information
about start-up and operating procedures for Nailor’s digital, analog,
and pneumatic controls. For specific information on controls
provided by other manufacturers contact the control manufacturer’s
local or national office. This applies whether the controls were
factory or field installed.
Note: Digital controllers may use specific communication
addresses based on Building Management Systems,
Architecture and original engineering drawings. Installing the
terminal in a location other than that noted on the label may
result in excessive start-up labor.
Primary Air Damper and Fan Adjustment
Before starting the fan motor, make sure duct system is free of
foreign objects, and filters are installed where required.
(1) Start motor and let it run-in at least 15 minutes. During run-in,
check ductwork connections for leaks and repair if necessary.
(2) All Nailor fan powered VAV terminal units incorporating PSC
motors use a solid state SCR speed controller to adjust motor
speed and consequently air volume. Speed controllers have built-in
maximum and minimum stops as detailed on the fan performance
pages in the Nailor VAV Terminal Unit catalog. Turning the manual
fan speed control counterclockwise will increase the fan speed;
clockwise will decrease speed. The fan speed control is located on
the side of the motor controls enclosure.
(3) For series units, set the unit to full cooling. Adjust and set
primary maximum cfm by measuring the airflow with a manometer
attached between the gauge ports in the pneumatic tube leading to
the high and low sides of the inlet air pick-up. A chart is attached to
the side of the unit showing airflow vs. pressure for different inlet
sizes. Adjust and set remote balancing dampers, if present. Do not
worry about airflow at this time; just proportion the outlets with the
dampers. Be sure to leave the dampers in the most possible open
position. This will generate the minimum noise level. Adjust the fan
speed control until the required CFM is obtained (by measuring the
air quantity at the room outlets or by zeroing the induction air if
primary and fan match). Fan should be adjusted with primary air at
maximum set point to ensure that no supply air is discharged at the
induction port. Recheck the fan and primary airflows when the
damper is reset to the minimum set point.
(4) For parallel units, turn the fan off, and set the primary air in the
same manner as described for series units. Proportion the diffusers
as above. Reset the primary airflow to the design fan turn-on point.
Measure the airflow again to verify proper airflow. Turn the fan on.
Allow the primary air damper to come under control after the fan is
started, and then adjust the fan until the prescribed airflow is
achieved by measuring the air quantity at the room outlets. Be sure
to allow the primary air damper to stabilize after each fan
adjustment and prior to measuring the airflow. Turn the fan off and
verify the minimum airflow point on the damper.
(5) For units equipped with ECM motors, set the primary air
dampers as described in (3). Set the fan as described on the ECM
MOTORS IOM, page 1. Proportion the dampers after the fan is set.
Remember to adjust the dampers so that they are in the most open
condition after proportioning. This will generate the minimum noise.
Maintenance Procedures
Fan and Motor
Nailor fan powered terminal units are equipped with permanently
lubricated motors. Inspect fan and motor assembly for dust and dirt
as often as dictated by operating environment. Clean assembly if
necessary.
If fan motor does not run, do the following:
a. Check for free rotation of blower wheel. Make sure no foreign
objects are in fan. Look for signs of freight or job site damage.
b. Check power supply. Disconnects should be in the "ON"
position.
Optional fusing should also be inspected. Check transformer for
proper output.
c. Check for proper control signals and PE switch setting (if
provided) and relay function.
Fan motor runs but emits excessive noise:
a. Maximum airflow may be too high, or discharge static
pressure may be incorrect.
b. Blower may have clearance problems. Make sure all
components are securely attached.
c. Verify integrity of ductwork. Leaks or loose connections
could cause noise. Check for rattling diffusers or rattling or
incorrectly adjusted balancing dampers.
Fan motor runs, but airflow too low:
a. May be due to ductwork restrictions, dirty air filters,
or clogged water coils.
b. Readjust fan speed control.
c. Discharge static pressure may be incorrect.
Check balancing dampers.

If repair or replacement is required:
Disconnect all power before servicing. Motor and fan should be
removed as an assembly. Remove the four hex nuts from the
mounting lugs holding the fan assembly to the discharge panel, and
remove the assembly through any convenient access panel. Do not
allow assembly to hang from wiring. If removing motor from blower,
first loosen the set screw holding the blower wheel to the motor
shaft. Remove the three screws holding the motor to the fan
housing, and slide motor and fan housing apart.
To put the assembly back together, reverse the procedure. Be sure
to align the blower set screw with the flat section of motor shaft.
Note: Over-tightening motor mounting screws may crush
isolation bushing, causing excessive fan noise.
Primary Air Damper Replacement
Nailor’s primary air valve assembly is not repairable. The entire
assembly should be replaced if it is damaged.
Labels
Each fan-powered unit is shipped with a nameplate label affixed to
the control casing. Principle nameplate data on the label typically
include Order-Serial number, Model number, Unit size, Motor
horsepower, Amperage, MOP, Heater (if present) data, Supply
Voltage, and Airflows. Also provided are calibration, airflow, as well
as other labels as necessary. We suggest that you read all labels
before beginning installation. If you have any questions, please
contact your local Nailor Representative. Their phone numbers can
be found on our website at www.nailor.com.
