Install Lighted Door Control Button
Locate push buttons where the garage door is visible (at a
height of at least of 1,5m), away from door and door hardware
and out of the reach of children.
Serious personal injury from a moving garage door may result
from misuse of opener. Do not allow children to operate the
lighted door control button or remote control transmitter.
Permanently fasten the caution label on the wall near the lighted
door control button as a reminder of safe operating procedures.
There are 2 screw terminals (1) on the back of the lighted door
control button (2). Strip about 6mm (1/4") of insulation from bell wire
(4). Separate wires enough to connect the white/red wire to terminal
screw 1 and the white wire to terminal screw 2.
Fasten the lighted door control button to an inside garage wall with
sheet metal screws (3) provided. Drill 4mm (5/32") holes and use
anchors (6) if installing into drywall. A convenient place is beside the
service door and out of reach of children.
Run the bell wire up the wall and across the ceiling to the garage
door opener. Use insulated staples (5) to secure wire. The receiver
quick connect terminals are located on the back panel of the opener.
Connect the bell wire to the terminals as follows: white/red to red (7)
and white to white (8).
Operation of the Lighted Door Control Button

Fasten Door Bracket
If yours is a canopy or dual-track one-piece style garage door, a door
arm conversion kit is required. Follow the installation instructions
included with the replacement door arm. Exercise care in removing and
assembling arm conversion kit. Keep fingers away from the sliding
parts.
NOTE: Horizontal and vertical reinforcement is needed for lightweight
garage doors.
Sectional and One-Piece Door Installation Procedure:
Door bracket (1) has left and right side fastening holes. Assemble
and install the bracket and plate (2) if your installation requires top
and bottom fastening holes.
1. Center bracket (with or without plate, as required) at the top of
inside face of door as shown. Mark holes.
2. A. Wooden doors
Drill 8mm holes (5/16") and fasten the door bracket with nut,
lock washer, and carriage bolt (3) or use wood screws.
B. Sheet metal doors

Position the Opener
NOTE: A 25mm (1") board (1) is convenient for setting an ideal door-
to-rail distance (unless headroom is not sufficient).
Raise the opener onto a stepladder. Open garage door. Place a
25mm (1") board (1) laid flat on the top section of door near the
centerline as shown. Rest the rail on the board.
If the raised door hits the trolley, pull down on the trolley release arm
to disconnect the inner and outer trolley sections. The trolley can
remain disconnected until connecting door arm to trolley is
completed.

Hang the Opener
The opener must be securely fastened to a structural support of
the garage.
Three representative installations are shown. Yours may be different.
Hanging brackets (1) should be angled (Figure A) to provide rigid
support. On finished ceilings, (Figure B) attach a sturdy metal bracket
(not supplied) (4) to a structural support before installing the opener.
For concrete ceiling mount, (Figure C), use concrete anchors (5)
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 (3/16") pilot holes in
the structural supports (or ceiling). Attach flattened ends of brackets
to supports with wood screws (2).
Lift opener and fasten to hanging brackets with screw, lock washer
and nut (3). Check to make sure rail is centered over the door.
Remove 25mm (1") board. Operate door manually. If door hits the
rail, raise header bracket. Use rail grease and lubricate bottom
surface of rail (6).
16
Attach Emergency Release Rope &
Handle
Thread one end of rope (1) through hole in top of red handle so
"NOTICE" reads right side up as shown (3). Secure with an overhand
knot (2). Knot should be at least 25mm (1") from end of the rope to
prevent slipping.
Thread other end of rope through hole in release arm of the outer
trolley (4). Adjust rope length so that handle is 1,8m (6 feet) above
the floor. Secure with an overhand knot.
NOTE: If it is necessary to cut rope, heat seal cut end with a match or
lighter to prevent fraying.
17
Install Light
Press the release tabs on both sides of lens (2). Gently rotate lens
back and downward until the lens hinge is in the fully open position.
Do not remove the lens. Install a 40 watt (socket size E27), maximum
light bulb (1) in the socket (3) as shown. The light will turn on and
remain lit for 2-1/2 minutes when power is connected. After 2-1/2
minutes it will turn off. Reverse the procedure to close the lens.
Replace burned out bulbs with rough service light bulbs.
18
Connect Electric Power
TO AVOID INSTALLATION DIFFICULTIES, DO NOT RUN THE
GARAGE DOOR OPENER UNTIL INSTRUCTED TO DO SO.
Connect the opener to a mains which is properly EARTHED
according to the wiring instruction tag attached to power supply
cord (and as specified by local code).
