FITTING THE UNIT
Fitting the motor centrally
1) Remove the motor from its positioning base "A". Mark the position of
the motor axis on the positioning base "A" (or on the optional extended
base "B" GLOPS2) and fasten the profile to the cross piece of the
garage door. The motor axis must be 70 mm below the hinged point of
the door arm "C". (for non flush fitting garage doors) or half way up for
flush fitting garage doors (see figs 2-3). The motor support, complete
with its extensions, must be fitted to the side of the lock and has to cover
at least three cross pieces "D", "E" and "F" (fig. 8) using a minimum of
three Ø 5 mm rivets for each cross piece.

2) Fasten the geared motor (axis in the chosen position) to the support
base "A" (or to the optional extended base "B" GLOPS2), with the
night light facing towards the top, using the two previously removed
screws and lock nuts.
3) The telescopic arm fastening brackets "G" can either be welded to the

fixed frame of the garage door (reinforce the welding area if the metal
sheet is less than 2,5 mm thick) or fixed to the frame/wall using two
M8 bolts.
At this point slide the tube "H" between the arms of the bracket "G"
and fasten down (don't over tighten) using the supplied M8 x 25 screws

and lock nuts.

4) Place the tube "H" (with the arm "R" inserted) parallel to the counter-
weight housing "L" and measure the distance "W" between the end
of the motor shaft "S" and the internal part of the straight arm "O" as
shown in figure 9. Subtracting 63 mm from the distance "W" will give
you the overall length of the motor shaft extension tube (fig. 2,3).
Follow the same procedure to measure the cutting length for the other
extension tube.
Remember to file down the sharp edges after cutting.
5) Position the support brackets "M" (fig. 9) at the same height as the
geared motor axis and drill two Ø4 mm holes with which to fix the
bracket to the garage door framework.
6) Assemble the 316/GLOTG group (fig. 2-3) motor shaft extension tubes,
8
threaded joints and relative
supports and then fasten

down the support tubes
using the supplied 4,8 x
16 self-tapping screws.

7) Measure the distance
between the motor axis
"P" and the axis of the tel-

escopic arm hinge hole "Q"
with the garage closed "x"
and with the garage door open
M
"Y".
Cut the tube "H" and straight
arm "R" to the minimum meas-
ured size (minus a play of 2 cm).
Remember to file down the sharp
L
edges after cutting.
Reassemble and fasten down the
arms using the supplied M8 grub
screws.
8) Drill the extension tube as follows:
- Make sure that the garage door is closed and the geared motor is
free;
- Using a Ø10 mm drill bit make a hole in the centre of the joint "N"
(fig.2-3) which passes half way through the tube.
- Insert the Ø10x50 elastic pin halfway through the tube.
- Open the garage door and drill the joint from the other side then allow the
elastic pin to outcrop the same distance on both sides of the joint.

1) Once you have decided upon the correct assembly diagram follow
points 1,2,3 and 7 of the previous paragraph.
In this case there are two motor supports and they should be fixed to
the extreme right and left of the garage door maintaining a distance of
9
65 mm from the counterweight housing as shown in the drawing.
2) Insert the threaded joint of the telescopic arm directly into the threaded
shaft of the motor, push it well in, and fasten down using the supplied
grub screw.
3) Check that the door is well balanced by manoeuvring it manually. The
weight of the motor means you will have to increase the counter weights

by about 10 kg on each side.
4) Compensate the counter weights
until the garage door is perfectly
balanced.
