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.

Inner Bracket

OuterBracket

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


6

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.

2.5 Installation of Accessories

2.5.1 Coupled Accessories

Coupled Accessory with Ceiling Mounted Unit

Mounted Coupled Accessory


8

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.

2.5.2 Decoupled Accessories

Ceiling hung decoupled accessories will not come with hanging brackets and can be supported in the ceiling with 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 CO2/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 effects 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 affected 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 affected. 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 effects 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 affected 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 RequirementsUnits can be lifted by mounting angles. Lifting directly from the frame is not recommended.
