A) PRELIMINARY CHECKS
-
Check that the door is well built.
-
Check that the door fits the frame correctly.
-
The door must move smoothly when manually opened and closed.
-
The door gear should be checked for friction and lubricated.
-
It is advised to fit rubber buffers to the door and frame. They will reduce the noise as the door strikes the open and close
position stops, and keep the door a few degrees inclined while opening so that it is easier for the operator to start the closing
movement.
B) SINGLE PIECE COUNTER BALANCED DOOR (Fig. 3)
The side brackets must be fitted to the door with supporting
flanges facing outside. The operator - side brackets must be
centrally mounted on the door with the output shaft below, at least
5 cm from the hinge pivot of the balancing arm and the door.
The correct installation method is as follows:
1) Adjust the side fixing brackets for the door.
2) Fit the brackets to the unit using the eight M10 screws
provided.
3) We recommend that all welds are tacked first, and only fully
welded when correct positioning is achieved. Weld the side
fixing brackets to the door frame, making sure the assembly is
exactly vertical.
4) Move the door to the closed position and release the
emergency device.
Insert an axle shaft and turn it to run the operator up to the limit
stop.
Then turn it back 5° (see Fig. 4) to stop the piston heads from
reaching the far end.
The position achieved is with the door closed: it cannot be
modified until the installation is completed.
5) Install the telescopic arms, adjusting their length to the
balance arms of the door. Weld the telescopic arm bracket
(No 4 - Fig. 2) to the door frame, making sure that sufficient
travel is allowed on the telescopic arm (25 - 35 cm minimum).
6) Insert the differential shafts in the shaft of the operator,
adjusting their length to the width of the door; fit the bearing
(No 6 - Fig. 2) and the stop ring.
7)Tack weld the differential shafts to the telescopic arm and the
bearing to the door frame. It is important that the differential
shafts are horizontal.
8) Manually open and close the door to check that all the
components are correctly positioned and that the door works
normally.
9) If you are satisfied, fully weld and reconnect the release
device.
