Installation and Connection
sealed. This is done using the DEKAsyl MS adhesive sealant supplied, which is ideally suited for this purpose due to
its broad range of adhesion. Please note the following points:
–
Before you start working with the DEKAsyl MS adhesive sealant, it is essential that you have carefully read
through the safety data sheet for the DEKAsyl MS adhesive sealant and the technical data sheet in this
installation manual!
–
The prerequisite for good adhesive properties is a clean, dry and grease-free substrate. Therefore, clean the
roof surface with a suitable cleaning agent within a circumference of 35 cm around the drilled hole and allow the
surface to dry thoroughly.
–
If the surface is painted, ensure that the paint finish is sufficiently well bonded to the substrate.
–
If the coat of paint is already loose or peeling, remove it down to a stable layer in the area to which the adhesive
will bond. If you have any doubts concerning the adhesive properties, consult a paint and lacquer specialist or the
manufacturer of your vehicle.
9. The procedure for gluing the mounting plate is as follows:

–
Ensure before starting adhesive work that the processing temperature of materials to be glued and the adhesive
sealant is b5 °C and +35 °C. Prepare all necessary fastening elements and tools.
–
Prepare the tube of adhesive sealant in accordance with the instructions enclosed with the tube.
–
Remove the roof duct (Fig. A) and apply the adhesive sealant evenly to the underside of the roof duct flange.
–
Place the roof duct in the drilled hole and press it firmly against the roof of the vehicle.
–
Apply the adhesive sealant evenly to the underside of the mounting plate, completely covering the area within the
circular groove (Fig. D). This area of the vehicle roof must be completely coated with adhesive in order to achieve
the necessary bonding force.
–
Place the mounting plate onto the roof of the vehicle, as you did previously when marking out the drilled holes.
Make sure that the arrow on the mounting plate points forwards in the direction of travel of the vehicle and that
the fastening holes are perfectly aligned with the prepared holes in the roof.
–
Fasten the mounting plate in place with the prepared screws, evenly tightening six screws across the diagonals.
NOTICE
Risk of material damage due to applying too much force when tightening the screws!
The adhesive sealant used is capable of filling small gaps caused by the curvature of the vehicle roof. If you
apply too much force when tightening the screws, the mounting plate could be bent.
►
Tighten the screws carefully.
–
Use a clean colourless cloth to remove any adhesive sealant that leaks out at the sides. Pay attention to the
following:
~
Do not use any cleaning agents or thinners containing solvents, as this could damage the adhesive sealant
applied under the mounting plate.
~
It is recommended to soak the cloth in acetone or MEK. Apply the cloth soaked in acetone or MEK to an incon-
spicuous area to make sure that it does not adversely affect or damage the surface.
~
Use only cleansing paste and water to clean your hands.
