Installation of the ELEVO gearmotor comprises 3 stages:
• Assembly of the guides (see sections 3.2.1 and 3.2.2).
• Mounting the gearmotor to the guide (see section 3.2.3).
• Mounting the gearmotor to the ceiling (see section 3.2.4)
3.2.1 - ASSEMBLY OF GUIDE
NOTE: the guides to be assembled are only available for the
ELEVO620 model.
1. Referring to fig. 4, remove the belt tensioner device (4a); insert
one end of the belt into the pulley (4b); reintroduce the belt
tensioner device into the guide (4c).
2. Pass the same end of the belt through the head [A],
as in fig. 5.
NB - Make sure that the belt is correctly positioned: it
must be with the teeth facing inwards, straight and
without twists.
3. Turn the lower section of the carriage so that the grooves
correspond with the two ends of the belt, as in fig. 6.
4. Place both ends of the belt into all the shaped slots of the
lower carriage [B]. Secure the ends of the belt with the 2
screws (V4.2x9.5) and 2 washers (R05), as in fig. 7.
5. Fix the belt guide [C] to the upper carriage [D] with the V6x18
screw and related M6 nut, as in fig. 8.
6. Insert the upper carriage [D] into the lower carriage [B] and
place the entire carriage assembly inside the guide, as in fig. 9.
7. Hammer the three pieces of the guide into place inside the
connection brackets [E], as in fig. 10 and 11.
Important – the guides must slide into the brackets until
they click into position.
8. Carefully position the belt into the guide, making sure that it is
not twisted.
9. Push the head [A] into the free end of the guide using
significant force, as in fig. 12.
10. Finally, tension the belt with the adjustment screw [F] of the
belt tensioner device, as in fig. 13.

CAUTION! the gearmotor could break if the belt is
TOO taut, and it could cause unpleasant noise if it is TOO
slack.
