WARNING!

ARNING!

ARNING!

Keep hands clear of the dampers when they are moving. Risk of personal injury.

Openings with dampers should always be covered by ducts.

Any unducted air dampers should be fitted with a protective grille (not included in Munters delivery) to prevent

injury from the damper blade movement.

Damper maintenance

Clean and check the operation of the dampers, the gearing and bearings.

The blades can be cleaned with water or compressed air.

Check the position in respect of the indications “OPEN” and “CLOSED”.

If the dampers do not move freely, lubricate the gearing and bearings with silicone oil.
