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.
To guarantee correct operation the tube "H" with its straight
arm inserted must be able to move within a minimum space
of 20 mm between the door arm "C" and the counterweight
housing "L". If the available space is inferior you will have to
use a curved arm.
4) Place the tube "H" (with the arm "R" inserted) parallel to the
counterweight 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 pro-
cedure 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, threaded
8
joints and relative sup-
ports and then fasten
down the support tubes
using the supplied 4,8 x
16 self-tapping screws.
7) M easure the distance
between the motor axis
"P" and the axis of the
telescopic arm hinge hole
"Q" with the garage closed
"x" and with the garage door
open "y".
Cut the tube "H" and straight
arm "R" to the minimum
measured size (minus a play
of 2 cm). Remember to file
down the sharp 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.
9) Check that the door is well balanced by manoeuvring it manu-
ally. The weight of the motor means you will have to increase
the counter weights by 4-5 kg on each side.
Compensate the counter weights until the garage door is
perfectly balanced.
Fitting the motor laterally
1) Once you have decided upon the correct assembly diagram
follow points 1,2,3 and 7 of the previous paragraph. In this
9
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 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
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
perfectly balanced.
