Installation of Flat Access Door

In order to install the flat access doors, you must first apply (stick) a self-adhesive template on a duct (a template is provided with each door). Second, the aperture has to be cut out (there is a tolerance of 3mm). Third, the doors are installed by unscrewing the hand knobs until a thread is levelled up with the top of the bolt. Using both hands, place the door in the hole at an angle, turn it straight and pull it out slightly to align. Then tighten the knobs.
