HANG THE OPENER 13

The opener must be securely fastened to a structural support of the garage. Attach the hanging brackets toward the front of the opener as shown (1).

Three representative installations are shown. Yours may be different. Hanging brackets (2) should be angled (Figure A) to provide rigid support. On finished ceilings, (Figure B) attach a sturdy metal bracket (not supplied) (5) to a structural support before installing the opener. For concrete ceiling mount, (Figure C), use concrete anchors (6) 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 (3).

Lift opener and fasten to hanging brackets with screw, lock washer and nut

(4). 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.

ATTACH MANUAL RELEASE ROPE & HANDLE 14

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.

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).

Connect the door opener only to an outlet controlled by a double pole switch.

INSTALL THE LIGHTED DOOR CONTROL BUTTON 15

Locate push buttons where the garage door is visible, 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.

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 or concrete. 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 terminal screws (7) are located on the back panel of the opener. Connect the bell wire to the terminal screws as follows: white/red to 1 and white to 2.
