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.

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.

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.
