Using a strip of cardboard about 0.3 mm thick (e.g. business card), check if pretension between panel seal - 2 - and body is even all around. Cardboard should slide through gap with firm resistance.
If pre-tension is insufficient, press seal reinforcement (inside rubber) open with a wedge - 1 - or, if pre-tension is excessive, close seal reinforcement slightly. Glass panel - 3 - must be removed before adjusting seal.
