IMPORTANT:

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.
