Function

Supply air is supplied with a 15° vertical angle deflection through the vanes into the space mixing with room air in front of the grille.

Wall installation for horizontal supply or ceiling installation for vertical supply.
In wall installations the recommended distance from the ceiling is 200 mm when the supply air is directed to the ceiling.

The grille can also be used as an exhaust unit.

Installation

Size of the installation hole is LxH when installation frame is used, and (L-5) x (H-5) without installation frame.

The grille is connected to the circular duct using either a Halton PRL balancing plenum or a Halton BDR plenum or alternatively directly to the rectangular duct using the IF/ALE installation frame.

Fastening options

Clips, as standard (CL)

The grilles are supplied with clips fastening as standard.
Clips fastening is used with IF/ALE, Halton PRL and Halton BDR.

Concealed screw (CC)

Concealed screw fastening is possible when the grille is installed with an installation frame (IF/ALE) or a Halton BDR plenum, though not with a Halton PRL balancing plenum.

Holes for screws are provided in the Halton BDR.

For ceiling installation concealed screw fastening is recommended.

Visible screw

Visible screw fastening is not possible due to the reduced width of the frame (18 mm).

Adjustment

In order to enable airflow adjustment and measurement of airflow rate it is recommended that you connect the diffuser to the Halton BDR plenum or Halton PRL balancing plenum equipped with the MSM module.

The supply flow rate is determined by using the MSM measurement and adjustment module.
Detach the grille and pass the tubes and control spindle through the grille.
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.

Replace the tubes and spindle in the plenum and replace the grille.

Airflow adjustment damper OD/ALE

The airflow rate is adjusted by turning the damper blades (1) behind the grille using a screwdriver. The measurement is carried out when grille is installed.

Servicing

Remove the grille by gently drawing it out by the frame. Use a screwdriver if necessary.
Clean the parts by wiping then with a damp cloth.
Push the grille back into place so that the clips lock (or fix by tightening the concealed screws).

Option:
With balancing plenum Halton PRL or Halton BDR + MSM

Remove the measurement and adjustment module by gently pulling the shaft (NB. not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth, instead of immersing in water.
Reassemble the measurement and adjustment module by pushing the shaft until the module meets the stopper.
Push the grille back into place so that the clips lock.

Specification

The grille has horisontal fixed vanes with a 15° angle deflection and an 18 mm wide flat frame, anodised or polyester-painted with a white (RAL 9003) colour.

Option 1

The grille can be connected to the ductwork using a plenum with mineral wool as sound insulation material.

Option 2

The grille can be connected to the ductwork using a balancing plenum, which comprises polyester fibre with a washable surface as sound attenuation material.
The plenum comprises an airflow measurement and adjustment unit.
The grille is removable in order to provide access to the measurement and adjustment module in the plenum.
