Function Air is supplied into the space through the side slots and front panel of the diffuser and mixes with the room air outside the diffuser The throw pattern can be deflected in different (1, 2, 3 and 4) directions with the deflection panels Recommended maximum air temperature difference between supply and room air in cooling situation is 10 C. Installation CODE DESCRIPTION 1 Front panel 2 Deflector panel 3 Deflector plate 4 Spring 5 Plenum The terminal unit is connected directly to the duct by screwing or riveting. The desired flow pattern is selected during installation with the deflector panels. The recommended minimum safety distance in front of the terminal unit is 3xD. In an exhaust application neither deflector panels nor deflector plate are used.

Adjustment CODE DESCRIPTION 1 Front panel 2 Measurement and adjustment module 3 Pressure test plug 4 Equalisation plate 5 Plenum The supply volume flow rate is determined using the measurement and adjustment module MSM. Open the front panel and equalisation plate. Pass the tubes and control spindle through the equalisation plate and side slot of the diffuser. Replace the front panel. Measure the differential pressure using a manometer. The flow rate is calculated using the formula below. q v = k * p m K-factor for installations with different safety distances (D= duct diameter) SUPPLY AIR TBV >8XD min 3XD 100 6.0 8.5 125 10.0 13.0 160 17.1 22.8 200 27.5 32.1 250 47.9 55.5 EXHAUST AIR TBV k 100 8.8 125 21.8 160 21.8 200 51.2 250 53.2 Adjust the airflow rate by rotating the control spindle until the desired setting is achieved. Lock the damper position with a screw. Reassemble the tubes and spindle into the plenum and replace the diffuser front panel. The exhaust flow rate is determined by using the separate measurement module located in the equalisation plate. 4

Servicing Open the front panel of the diffuser and clean the parts by wiping with a damp cloth. Remove the equalisation plate, and measurement and adjustment module by gently pulling the shaft (not the control spindle or measurement tubes!). Wipe the parts with a damp cloth, instead of immersing in water. Reassemble the equalisation plate, and measurement and adjustment module by pushing the shaft back into place until the unit meets the stopper. Push the front panel back into place so that the springs lock. Suggested specifications Product code TBV/S-D S = Construction A Supply with MSM module B Exhaust with MEM module D = Diameter of duct connection 100, 125, 160, 200, 250 Specifics and accessories CO = Colour W White X Special colour The diffuser and plenum shall be made of painted steel with a white (RAL 9010) colour. The diffuser shall diffuse the supply air into the space through the side slot and perforated front panel, ensuring a high mixing rate. The flow pattern of the diffuser shall be adjustable in a 1, 2, 3 or 4-way direction by shaping the deflector. Code example TBV/A-100, CO=W The diffuser shall be integrated to a balancing plenum equipped with a measurement and adjustment module. The diffuser shall have a detachable perforated front panel in order to provide access to the measurement and adjustment module in the plenum. The balancing plenum shall have a spigot equipped with integral gasket for airtight duct connection. 14
