Attaching drive to header

It may be necessary to place the drive temporarily higher, so
that the rail does not hit the springs in sectional doors.
The drive must either be well supported (ladder) or held firmly by
a second person. Put drive head on garage floor under the lintel bracket.
Lift rail up till the holes of the fixing part and the holes of the lintel bracket
are aligned. Insert screw (14) through the holes and secure with nut (15).

Hang opener

Fully open the door, put down door opener on the door (Fig. A).
Lay a piece of wood / cardboard on the marked spot (X).
The opener must be securely fastened to a structural support of the
garage.
Three representative installations are shown (Fig. B).
Yours may be different. Hanging brackets (12) should be angled to
provide rigid support. On finished ceilings, attach support bracket(not
delivered) to a self-supporting structio-nal element before installing the
opener. For con-crete ceiling mount, use concrete anchors (22) provided.
On each side of opener measure the distance from the opener to the
structural support (or ceiling).
Cut both pieces of the hanging bracket to required lengths. Flatten one
end of each bracket and bend or twist to fit the fastening angles.
Do not bend at the bracket holes. Drill 4,5mm pilot holes in the structural
supports (or ceiling). Attach brackets to supports with wood screws (20).
Lift opener and fasten to hanging brackets with screw and nut (17). Check
to make sure rail is centered over the door.
Remove piece of wood / cardboard. Operate door manually.
If door hits the rail, raise header bracket.
After the installation of the garage door drive, particularly using a rail
extension, if the rail is observed to be bent up or down for more than 5 cm
during the beginning or end of the travel as well as while encountering an
obstacle, a central suspension must be provided by the customer.
For this, please contact the manufacturer of the garage door drive.
Pay attention to a horizontal course of the rail along the ceiling.
The distance can be adjusted by the given hole spacing.
Protruding ends of the ceiling fixture can be reduced if necessary.

Locate door control where the garage door is visible, away from door and
door hardware and out of the reach of children. Mount at least 1,5 m (5
feet) above the floor. Permanently fasten the caution label permanently to
the wall near the door control as a reminder of safe operating procedures.
There are 2 terminals on the back of the door control. Strip about 6mm of
insulation from bell wire. Separate wires enough to connect the white/red
wire to RED terminal screw and the white wire to WHT terminal screw.
Fasten the door control to an inside garage wall with sheet metal screws
(3) provided. Drill 4mm holes and use anchors (6) if installing into drywall.

Run the bell wire up the wall and across the ceiling to the garage door
opener. Use insulated staples (5) to secure wire.
Operation of the Door Control:
