Odour-tight back-draft damper for square ducting
INSTALLATION
Insert the damper between ducting. Ensure the airflow direction is correct.
CAUTION: Do not use any sharp tools. They could damage the membrane. The
damper is not designed for use in aggressive environments.
MAINTENANCE
GBV back-draft damper components repel dirt and are maintenance-free. However, when used in a humid and dusty environment, you should periodically check their perfect cleanliness. Clean components using a soap solution when soiled.
WARRANTY CLAIMS – DISCLAIMER
Failure to follow the above instructions will void our warranty.
MAGNET ADJUSTMENT
The strength of the magnet can be adjusted using the steel screw, which
modifies the damper closing force.
Simply tighten or loosen the screw as needed with a Phillips screwdriver. To
increase the pull, loosen the screw closer to the magnet. At the same time,
care must be taken to ensure that the screw does not protrude too much and
that the damper is able to close completely. Higher negative pressure in the
duct may be the reason this step is required .
