PVC door/sash
Wooden door/sash
Aluminium door/sash
This step requires a certain precision in the drilling and driving of the screws that secure
the various sections of the rack so that it is properly fitted to the door/sash and perfectly
aligned, and to therefore ensure that the gearmotor works perfectly.
9.2. Mounting the gearmotor on the frame
9.2.1. Preparing for mounting
A previous section
(section 9 - Risk analysis)
recommends making a prior analysis of
where to position the gearmotor, the path of the power cables and where to fix the support
brackets. The following description is a recommendation by the manufacturer and
describes the main installation steps, the sequence of which also depends on the type of
sliding door/window used and its structure.
The gearmotor is supplied with a flat bracket for the standard fitting (the most common),
although a bracket for 90° fitting (on the reveal of the frame) is also available. In the event
of special anchoring requirements, appropriate solutions can be studied.

The screws for fixing the bracket to the gearmotor are supplied (
M5x14 metric flat head
screws
) and the bracket should be assembled on the gearmotor in the exact position
shown in the figures above, depending on how the gearmotor is mounted on the door/sash
(to the right or to the left).
9.2.2. Preparation and mounting of the gearmotor
For a professional, inexpensive and precise job, we recommend preparing the following
additional material: screws, equipment and tools.
Fixing on metal frames: M5 threaded inserts
(2 pieces)
, 2 M5x12 metric flat head
screws.
Fixing on wooden frames: Ø4.5 self-tapping wood screws
(2 pieces)
of a suitable
length for the type of frame.
Fixing on PVC frames: Ø4.8 self-tapping metal screws
(2 pieces)
of a suitable length
for the type of frame.
Equipment and tools: tape measure, pencil, electric drill/screwdriver, set of metal drill
bits, screwdriver bit, electrician's scissors, screwdrivers.
Before mounting the gearmotor on the frame or on the reveal of the door/window frame,
the fixing points must first be marked and drilled as indicated below:
a)
The gearmotor must be prepared by first inserting the pinion (z = 13) with the
hexagonal hole into the drive shaft and then the guide bushing (Ø4x6x6);
take care
not to drop or lose the bushing as it is essential for correct and silent coupling of the
pinion with the rack.
b) Insert the end of the shaft (with the bushing) into the housing on the rack.
c) Align the gearmotor as desired in accordance with the analysis made earlier; it is
recommended to place it in a horizontal or vertical position.
d) Mark the position of the holes for the bracket on the frame or the reveal with extreme
precision.
It is very important to achieve maximum precision at this stage in order for
the device to operate perfectly
.
e) Drill with a drill bit of the right size for the provided inserts or the right diameter for the
fixing screws.
On aluminium profile frames, it is recommended to use metric screws with threaded
inserts.
Once this is done, the gearmotor can then be mounted. For this step, it is advisable to
keep the door/sash open by at least 20 cm to facilitate start-up when setting the stroke end
positions.
Insert the power cable into the provided conduit until it reaches the inside of the
electrical junction box.
Insert the end of the drive shaft (with the bushing) into the housing on the rack.
Fix the gearmotor to the frame or to the reveal of the door/window frame with the
provided screws.
Adjust the position of the power cables and protect them inside a flexible conduit.
Carry out the electrical connections following the instructions in section 8.
