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.

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.

Suggested specifications

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.

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.
