sensor and all other optional field components will be
found in the electrical box or fan compartment. They
are secured there for transport and to easily find
them on the job site.

the fan section from the core section for ease of
installation and maneuverability in tight locations.
Use the following steps to disassemble the fan
section from the core section.
1. Remove the cover from the fan.
2. Undo the screw terminals that are holding the
power wires and the communication wires.
*See back of manual for electrical drawings.
3. Loosen the cable glands and pull the wires out of
the motor.
4. Pull the pressure tube from the nozzle port on
the fan bell mouth.
5. Push the pressure tube and all cables back into
the core section, through the rubber grommets
that are on the fan wall.
6. Repeat steps 1 ― 5 for the other fan.
7. Remove bolts for each corner and top shelf.
8. Pull apart the two sections.

2.4 Horizontal Installation
2.4.1 Front Doors
The hanging brackets are supplied loose with the
necessary hardware to install them. They are not
shipped assembled due to the variability of installation
access on job sites.
Each hanging bracket is composed of two pieces: an
inner component and an outer component. The units
are designed to have four sets of brackets to support
the unit.
Note Depending on the ducted opening location
selected during the design phase, the location of
the brackets will vary. Please consult your submittal
drawings for specific locations.

Warning
The unit must be installed with both the inner and outer bracket. Each unit must also have all four brackets installed
to meet these guidelines.

Assembly of Hanging Brackets
1. Locate the position of the brackets on the outside
of the unit.
2. Mark the 8 hole locations and drill to allow for
the ¼" bolt. 32 - ¼" bolts, 32 - ¼" lock nut, 32 - ¼"
washers and 64 - ¼" washers have been provided
with the unit.
3. Assemble the hanging bracket by aligning the 8
holes of the outer bracket through the unit and
with the inner bracket. Note: the inner component
should be oriented so that its flange is pointing to
the ceiling, and the outer bracket has the single
hole pointing to the ceiling.
4. Install the 8 bolts. Caution - Do not over tighten
and crush the panel.
5. Install 4 tek-screws in the flange portion of the
inner bracket and secure it to the top casing of the
unit.
6. Install 4 tek-screws in the lower flange of the outer
bracket to secure it to the bottom frame of the unit.
7. Repeat steps 1 through 6 for the remainder of the
brackets.
8. The hole in the outer brackets are designed for a
½" threaded rod to hang the units by.

2.4.2 Side Doors
When a Nova unit is ordered with side doors, there is no access to install hanging brackets and the unit must
be supported from below as seen in the image. The sizing of the supports is to be designed by the installing
contractor.
2.5 Vertical Installation
A floor mounted Nova unit will ship with an installed base rail. These units can be installed directly on the floor or a
housekeeping pad.

2.6.2 Vertical Coupled Accessories
Base mounted accessories that are connect to a duct connection in the lower position of the unit will come with
matching base rails.
Accessories that are to be connected to a duct connection in the upper position will need to be supported
externally. This can also be done with Unistrut or similar.

2.6.3 Decoupled Accessories
Ceiling hung decoupled accessories will not come with hanging brackets and can be supported in the ceiling with
Unistrut and threaded rod or equivalent.
Accessory modules can come with base rails for floor mounting.

2.7 External Sensors
2.7.1 Supply Air Temperature Sensor
TTH-6202 sensors are installed in the ventilation
duct using the accompanying bracket, which must
be attached to a firm, level surface by means of
two screws. The supply voltage is provided via the
Modbus connection. TTH-6202 has a pre-fitted cable,
which is equipped with a standard RJ12 connector.
The cable may be extended up to 50 m using a
Category 3 extension cable. The sensor must be
mounted according to, and must be aligned parallel to
the air flow in the center of the duct.
5'*
*Sensor must be installed a minimum of 5' from the heating or cooling module.
2.7.2 Pressure Sensor
Sensor must be installed ⅔ of the way
down the duct in the duct path that
would result in the most pressure drop.

2.7.3 CO/VOC Sensor
VTH-6202 sensors are installed in the ventilation
duct using the accompanying bracket, which must
be attached to a firm, level surface by means of
two screws. The 18-30 V DC supply voltage (24 V
DC nominal voltage) is provided via the Modbus
connection. VTH-6202 has a pre-fitted 7000 mm cable,
which is equipped with a standard RJ12 connector. The
cable may be extended to as much as 50 m without
any negative eects on measuring accuracy. The
surrounding EMC environment must, however, be taken
into account and must be capable of being defined as
low. To extend the cable, use a crossover Category 3
extension cable, RJ12-RJ12, 6P6C. The sensor should
be installed in such a way that the air flow in the duct
can pass unhindered through the measuring hole
at the end of the sensor, which should be aligned
parallel to the air flow. Although the VTH-6202 is not
aected by the position in which it is installed, it should
not be installed in an upright position with the cable
downwards as this may cause moisture to accumulate
in the sensor.
The enclosure is opened without the use of tools
by pressing the snap lock at the side of the tube
connectors. PTH-6202 is attached onto a level
surface by 2 screws, which are screwed into a solid
surface. PTH-6202 can be fitted in all directions
without accuracy being aected. PTH-6202 also
functions with only one tube fitted to the connectors
(+ or -). However, two tubes should always be fitted to
ensure a suitable enclosure rating, if the connectors
do not face downwards. Pressure is supplied to the
measurement unit by tubes, the highest pressure
being connected to the ‘+ connector’ and the lowest
pressure to ‘- connector’. The pressure tubes must be
as short as possible and must be secured in position to
prevent vibration. To obtain the best possible results,
pressure must be measured where there is least risk
of turbulence, i.e. in the center of the ventilation duct
and at a distance of at least twice the width of the duct
from bends and six times the width from branches. If
there is a risk of condensation forming in connection
tubes, PTH-6202 is to be located in such a way that
condensate fluids cannot flow back into the pressure
transmitter.

2.7.4 Combination Temperature/
Humidity Sensor
HTH-6202 sensors are installed in the ventilation
duct using the accompanying bracket, which must
be attached to a firm, level surface by means of
two screws. The 18-30 V DC supply voltage (24 V
DC nominal voltage) is provided via the Modbus
connection. HTH-6202 has a pre-fitted 7000 mm
cable, which is equipped with a standard RJ12
connector. The cable may be extended to as much
as 50 m without any negative eects on measuring
accuracy. The surrounding EMC environment must,
however, be taken into account and must be capable
of being defined as low. To extend the cable, use a
crossover Category 3 extension cable, RJ12-RJ12,
6P6C. The sensor should be installed in such a way
that the air flow in the duct can pass unhindered
through the measuring hole at the end of the sensor,
which should be aligned parallel to the air flow.
Although HTH-6202 is not aected by the position
in which it is installed, it is advisable not to install
the sensor in an upright position with the cable
downwards as this may cause moisture to accumulate
in the sensor. It is important that HTH-6202 is installed
in such a way that the measuring hole is positioned at
the center of the duct.

3.0 Access Requirements
Top of Unit
The National Electrical Code (NEC) stipulates that there must be a minimum of 36 inches of clearance from an
electrical connection. The installing contractor must ensure there is at least 36 inches of clearance perpendicular to
the top of the electrical box.
Front of Unit
In order to open the doors of the unit, the installing contractor must leave 48 inches perpendicular to the doors.
If there is no intention to open the doors fully, they can be removed for servicing, by removing the hinge pins and
lifting o the doors.
4.0 Lifting Requirements
Horizontally Installed Units
Once the mounting angles have been installed, the unit can be lifted by the
angles.
Vertically Installed Units
A vertically installed unit that is delivered with base rails, can be lifted from
the base rail with the use of a spreader bar to prevent damage to the unit.
