CAUTION:

Do not grip bonding surface.
It is not the length of pressing in time but rather the level of pressing (approx. 10 ... 15 N/cm² ) which is decisive here.
Separation of seal after pressing destroys the adhesive layer.

NOTE: After being pressed on gently, seal can be pulled off again up to 3 times. Do not dirty adhesive area.

Suspend seal (1) with open lip pointing inwards over door. Pull protection of positioning aid (liner) off seal in sections.

Stick on seal (1) as follows:

Position seal with color coding on door window frame at front top.
Gently press seal without stretching up to start of positioning aids.
Check positioning of seal, correct if necessary (sag max. 30 mm).
Firmly press down seal vertically to adhesive area up to above-mentioned area.
Gently press seal without stretching up to entrance area.
Check positioning of seal, correct if necessary and firmly press.
Pull remaining protective film (liner) off seal.
Press remaining seal without stretching.
