heights due to falling slide-in module (3.6 kg).
Sometimes the slide-in module is hard to pull out
of the wall sleeve/slide into the wall sleeve. Use
appropriate, certified climbing aids (ladders). Sta-
bility should be ensured, if necessary have the
ladders steadied by a 2nd person. Ensure that
you are standing securely and cannot lose your
balance and that there is no one under the unit.
When installing and removing the slide-in mod-
ule, support it from below with a hand.
