Check of door balance
Make sure, the door is free-mov-
ing and well balanced.
Lift the door halfway up and
release it. If balanced, the
door stays in this position only
by force of its springs. Call a
trained door systems technician,
if the door is out of balance or if
it binds.
Check of door gap
Make sure, the gap between
the closed door and the fl oor is
less than 6 mm. Otherwise the
reversal system may not work
properly.
