Doco DOCOMATIC 1200, Installation Manual

Page: 11 / 23

• Put all those mechanical locks and devices of the garage door, which are not required after installing the drive, out of
operation and remove them.
• Please note that the drive is installed with the garage door closed: all tools and tackles required must be kept inside the
garage if it does not have any other access route.
2.2 Pre-assembly of the drive
FIG. 6: Pre-assemble the rails
• Depending on the model of the equipment, the rails must first be pre-assembled. First plug the rails into one another with
the help of the cap rails. The rails must be pushed into one another up to the stop points.
FIG. 7: Put the chain / toothed belt in place
• Pull the chain / toothed belt already in the rail in the direction of the open end of the rail. When doing so, please ensure
that the attachment (a) is located on the correct side of the rail.
FIG. 8: Mount the head retainer (toothed belt version)
• Pull the head retainer (1) out of the rail (2). Remove the transportation lock (3). Place the drive wheel (4) into the ball-
bearing and push the head retainer back into the rail.
FIG. 9: Mount the head retainer (chain version)
• Pull the head retainer (1) out of the rail. Attach the sprocket (4) and the transportation lock (3) and push the head retainer
back into the rail.
FIG. 10: Put the rubber liner in place (only chain version)
• To prevent vibrations at the points marked with "c", affix the self-adhesive rubber liner as close as possible to the end of the
rail in the front (a) and at the rear (b).
FIG. 11: Mount the clamp
• Pull the chain / toothed belt already in the rail in the direction of the open end of the rail. When doing so, please ensure
that the attachment (a) is located on the correct side of the rail.
• Next, fix the deflection roller assembly to the clamp as shown. While doing so, please ensure that the square-shaped end
of the mushroom head bolt is correctly seated in the deflection roller assembly holder.
FIG. 12: Tighten the drive medium
• The chain or the toothed belt must then be pre-tensioned to such an extent that the chain or the toothed belt does not
drop down any longer.
FIG. 13: Test the carriage
• Finally, check whether the carriage can be moved easily in the rail. To do this, operate the emergency unlocking lever on
the carriage and move it in the rail simultaneously.
• Make sure to check that the carriage is latched onto the attachment after this test. For this purpose, move the carriage
over the attachment, while the emergency unlocking lever is not in operation, so that the carriage latches automatically.
FIG. 14: Mount the door fitting
• Different installation parts can be used for those versions of the appliance with a straight push rod (a): the straight exten-
sion can be used for overhead tilting doors (d) and the sectional door bracket (c) can be used for sectional doors. The
standard version of the equipment uses a curved push rod (a) and no other installation parts are supplied or used.
• Following this, the door fitting (b) is mounted on the push rod (a).
2.3 Installing the drive
FIG. 15: Mark the centre of the door
• Measure the width of your door and mark the centre of the door at the lintel, the upper edge of the door and on the
garage roof (behind the opened door and near the motor head).
FIG. 16/17: Obtaining the required height
• The rail must be mounted in such a way that there is about 10-20 mm clearance between the highest point of door mo-
vement (a) (the highest point that the top edge of the door can reach during its movement) and the bottom edge of the
rail (b). In the process, however, please ensure that the rail is always mounted horizontally.
• The angle α may not exceed 30°, otherwise proper power transfer cannot be guaranteed.
• The distance between the lower edge of the rail and the upper edge of the garage door must be between 5 and 7 cm
when the door is closed.
