Operating and Maintenance Manual



When connecting ductwork to dampers take care to ensure that damper casing is not twisted by ductwork and that fixings do not penetrate cog housing of the damper which will affect the damper mechanism. Ductwork must be independently supported and should not be left to hang from the damper. Sealing should be in the form of prestik or neoprene strip. Ensure actuator rotation is correct in relation to blade location to prevent breaking linkages.

At six (6) month intervals disconnect actuator and check for freedom of movement.
