2.1 Unwrapping the Product
When removing the shrink wrap, be cautious with
knives and sharp tools to prevent scratching the
paint.
The HMI, pressure sensor, external duct pressure
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.
2.2 Assembly
Remove the middle panel for wiring access. Fans
and filters are accessible via the bottom doors. Fans
should be pre-wired and no assembly is required.
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.

2.4 Installation
2.4.1 Ceiling Mount
Ventum is available exclusively for ceiling mount/
horizontal applications with inner and outer brackets
only. 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. The front panel of the unit must be
removed to slide the core into the unit.
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. Ceiling Mounted Unit

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.

Corner brackets come pre-installed with each Ventum unit. Accessories should be independently supported with
Unistrut on the end farthest from the unit. 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.

horizontal brackets and threaded rod or equivalent.

2.6 External Sensors
2.6.1 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.
*Sensor must be installed a minimum of 5' from the heating or cooling module.
2.6.2 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.

2.6.3 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.

2.6.4 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) requires 36 inches of clearance from an electrical connection. For Ventum, with
a front-mounted electrical box, the 3’ must be measured from the front of the box. The unit should be mounted such
that the bottom doors remain accessible.
4.0 Lifting Requirements
Units can be lifted by mounting angles. Lifting directly from the frame is not recommended.
