Function

Air is supplied into the space through the side slots and front panel of the diffuser and mixed 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 situations 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 with the deflector panels during installation.

It is recommended that the minimum safety distance before 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 airflow rate is calculated using the formula below.

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.

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.

Specification

The diffuser and plenum is made of epoxy-painted steel with a white (RAL 9003) colour.
The diffuser difsfuse the suspply air into the space through the side slot and perforated front panel, ensuring a high mixing rate.
Flow pattern of the diffuser i adjustable in a 1, 2, 3 or 4-way direction by shaping the deflector.

The diffuser is integrated to a balancing plenum equipped with a measurement and adjustment module.
The diffuser has a detachable perforated front panel in order to provide access to the measurement and adjustment module in the plenum.
The balancing plenum has a spigot equipped with integral gasket for airtight duct connection.
