Aldes MR Modulo: Adjustable Constant Airflow Regulator

READ AND SAVE THESE INSTRUCTIONS

SETTING THE AIRFLOW

Twist the rotating adjustment ring until the desired airflow is reached. Reference the correlation table at right and printed on the device. No tools required.

Illustration shows a small diameter Aldes MR Modulo device.

Illustration shows a hand rotating an adjustment ring on a larger diameter Aldes MR Modulo device to set the airflow.

INSTALLATION

The MR Modulo will push-fit into circular ducts in close proximity to a take-off or terminal. Orient the MR Modulo according to the airflow direction indicated on the device. Horizontal or vertical mounting is acceptable.

To avoid acoustic and aeraulic disturbance, provide the following distance between the device and the terminal (grille / diffuser / inlet):

Exhaust Air: 1x the device diameter Ø
Supply Air: 3x the device diameter Ø

Diagram illustrating recommended clearance distances for the MR Modulo in ductwork. For exhaust air, a distance of 1x the device diameter is shown. For supply air, a distance of 3x the device diameter is shown before the terminal (grille/diffuser/inlet).

MAINTENANCE

MR Modulo performance is not altered by clogging, therefore it requires practically no special maintenance.
If the intended application includes air heavily loaded with grease or dust, a fitting with an access panel or door, such as that used for flame dampers, should be used.
Clean with soaped water. When cleaning, plug the hole on the plastic body, at the base of the bulb, to prevent any obstruction and any penetration of liquid or foreign body inside the bulb.
