Function

Air is exhausted from the space through the egg crate core of the grille.
Wall or ceiling installation.

Installation

The grille is connected directly to the duct using either the installation frame or a Halton PRL balancing plenum or Halton BDR plenum.
Halton PRL is not available for all AGC sizes.

Clips fastening (standard)

The grilles are supplied with clips fastening as standard.
Clips fastening is used with installation frame (IF) or balancing plenums (Halton PRL and Halton BDR).

Concealed screw fastening (option)

Concealed screw fastening is possible when the grille is installed with an installation frame (IF) or with a Halton BDR plenum box.

In such cases, small holes are factory made in Halton BDR for each concealed screw.
Concealed screw fastening is not possible with Halton PRL plenum.
For ceiling installation concealed screw fastening is recommended.

Size of installation hole is LxH with an installation frame and (L-5)x(H-5) without installation frame.

Visible screw fastening

For ceiling installation the use of visible screw fastening is recommended. Bevel headed screws (4.2x25) are supplied with the grille.

Adjustment

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

The airflow rate can only be adjusted and measured when the grille is connected to the Halton BDR or Halton PRL plenum.

Define the exhaust airflow rate by measuring the pressure difference between the measurement tap on the Halton PRL or Halton BDR balancing plenum and the room air. The corresponding airflow rate is calculated using the formula below.

Adjust the airflow rate by turning the control spindle of the MEM.

Airflow adjustment damper (OD)

The airflow rate is adjusted by turning the damper blades behind the grille with a screwdriver. The measurement is performed when the 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 with a damp cloth.
Push the grille back into place until the springs lock (or by tightening the concealed screws).

Option:
Installation with balancing plenum Halton PRL + MEM or Halton BDR + MEM

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