PRE-INSTALLATION CHECKS
Before proceeding with installation, check the condition of the product
components, the suitability of the selected model and the suitability of
the intended installation environment.
IMPORTANT – The gearmotor cannot be used to power a door
that is not fully efficient and safe. Neither can it solve defects
caused by poor installation or insufficient maintenance of the
door itself.
3.1 CHECKING THE SUITABILITY OF THE
ENVIRONMENT AND OF THE DOOR TO BE
AUTOMATED
• When 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 being
automated and complies with local regulations.
• Check the sturdiness of the door's mechanical structure, ensuring
that the guides do not risk coming out of their seats.
• Move the door manually to open and close it, checking that movement
has the same degree of friction throughout all points of travel (no
increase in friction must occur).
• Make sure the door is properly balanced: in other words, if left
stationary (manually) it must not move from any position.
• Ensure that the space around the automation enables a safe and
easy manual release manoeuvre.
• Ensure that the surfaces chosen for the installation of the various
devices are solid and guarantee stable anchoring.
• Ensure that all devices to be installed are in a sheltered location and

protected against the risk of accidental impact.
• Ensure that the surfaces chosen for attaching the photocells are flat
and enable proper alignment between photocells.
3.2 CHECKING THE USAGE LIMITS FOR THE PRODUCT
To ascertain the suitability of the product with respect to the specific
features of the door and the area to be automated, the following checks
should be performed and their conformity should be verified against the
technical data in this paragraph and in the chapter "Product technical
specifications".
• Ensure that the dimensions and weight of the door are within the
following limits of use:
