PRELIMINARY INSTALLATION WORK
Before proceeding with installation, check the condition of the product
components, suitability of the selected model and conditions of the
intended installation environment.
IMPORTANT – The gearmotor
that is not fully efficient and safe
caused by poor installation or insufficient maintenance of the
door itself.
3.1 – CHECKING SUITABILITY OF THE ENVIRONMENT
AND THE DOOR TO BE AUTOMATED
• In the case of automating a projecting up-and-over door, ensure that
movement does not obstruct public roads or pavements.
• Ensure that the mechanical structure of the door is suitable for automa-
tion and complies with local standards.
• Check stability of the mechanical structure of the door, ensuring that
there is no risk of guides coming out of their seats.
• Move the door manually to open and close, checking that movement
has the same degree of friction throughout all points of travel (no increase
in friction must occur).
• Ensure that the door is correctly balanced: in other words, if left station-
ary (manually) it must not move from any position.
• Ensure that the space around the automation enables safe and easy
manual release.
