Mounting and operating instructions
4 MOUNTING
4.1 General
Attention:
It is recommended that a door leaf stop piece be mounted by the customer.
This stop piece prevents the door leaf from being damaged in the manual operating
mode.
Attention:
Check the free running movement of the door leaf. Should it fail to move smoothly and
silently, or if it is out of balance (i. e. it opens or closes by itself), these problems must
be eliminated first!
Warning:
The fastening bases must provide sufficient solidity. If necessary they have to be rein
-
forced by the appropriate means.
Attention:
The maximum admissible undulation of the fastening base is 1 mm. The drive me
-
chanism must be fastened without torsion and perpendicularly, using all the six fixing
holes!
