3. MECHANICAL INSTALLATION

See the relevant drawings of the mechanical installation at page. 22 - 23 (central sheet to be removed).
3.1 Checking the opening (fig.1).
• Check the dimensions of the opening, and their correspondence to the overall dimensions of the door supplied, taking into
consideration any necessary tolerances in the case of installation in an archway.
• Check that no existing structures obstruct the assembly of the door.
• Ensure the resting surfaces are level and, if necessary, adapt them using appropriate shims.
• Check the solidity of the opening: secure anchorage must be ensured by means of brackets or anchor plugs. In the case
of insufficient or dubious solidity, it is necessary to create an adequate self-supporting metal structure.
3.2 Fitting the uprights (fig.2).
• Measure the overall dimensions of the crosspiece (LT).
• Mark the exact position of the uprights on the floor.
• Remove the covers of the uprights and fix the bases according to the marks using special M8 size plugs.
• Plumb the uprights and fix them at the indicated points (A) with external brackets or (B) for fixing from inside column. M8
size plugs.
• Check that the installation is perfectly perpendicular by measuring the diagonals.
Do not drill holes in the right-hand upright near the counterweight sliding area (C).

3.3 Assembling the crosspiece

• Remove the M8 bolts preassembled on the ends of the crosspiece.
• Carefully lift the crosspiece using a forklift truck or other lifting equipment. Make sure that it cannot fall while being lifted
and protect the door section from being damaged (fig.3).
• Place the crosspiece on the uprights, reinsert the fixing bolts and tighten them (fig.4).
• For doors with PL > 4000 we recommend fastening the crosspiece in the centre (to avoid unsightly bending of the frame).

3.4 Assembling the counterweights

• Completely unroll the belt leaving 1 spare turn wound around the winding drum and passing the belt around the transmission
pulley (fig.5).
• Fix the belt in place using the special plaque (fig.6). Adjust the length of the belt so that the threaded bar remains
approximately 200 mm off the ground (when the door is wide open).
• Finely adjust the balance using the 4 lower counterweight elements.

3.5 Assembling the emergency release lever

• The emergency release lever must be assembled on the structure itself or on the wall at a minimum height of 1.8 m off
the ground (fig.8).
• If it is assembled on the structure, use the measurements indicated in (fig.9) and place the drive cable in the spaces and
connect it to the gearmotor brake (fig.10).
• Check that the device is operating correctly; when the lever is operated, the door section should be free to rise.
3.6 Installing the photocells
• Install the containers in the column covers. For installation and connections, follow the instructions in the photocell package.

3.7 Installing the safety edge

• Place the door section at a height of approximately 1 m.
• Insert the safety edge into the lower pocket of the door section (fig.11).
• Run the edge along the entire length of the door section and place it in the exact centre of the curtain.
• Insert the sliding blocks in the aluminium profile and fasten them using the self-tapping screws and placing them on the special
plastic spacers.
• Connect the free end of the cable chain to the nylon sliding block of the safety edge, (fig.12).
• Insert the sliding blocks in the aluminium profile and fasten them using the self-tapping screws and placing them on the special
plastic spacers.
• Fix each side of the curtain to the corresponding sliding block using a self-tapping screw (d) (fig.12).
