INSTALLATION SECTION 11 – 19

Wear protective goggles when working overhead to protect your eyes from injury.

Disengage all existing garage door locks to avoid damage to the garage door.

To avoid serious personal injury from entanglement, remove all ropes connected to the garage door before installing the opener.

Installation of this product shall comply with ZH1/494, VDE 0700 Part 238, and VDE 0700 Part 1.

It is recommended that the opener be installed

2,1m (7 feet) or more above the floor where space permits.

POSITION THE HEADER BRACKET – 11

The header bracket must be rigidly fastened to a structural support of the garage. Reinforce the wall or ceiling with a 40mm (1-1/2") board if necessary. Failure to comply may result in improper operation of safety reverse system.

You can attach the header bracket either to the header wall (1) or to the ceiling (3). Follow the instructions which will work best for your particular requirements.

With the door closed, mark the vertical centerline (2) of the garage door. Extend line onto header wall above the door.

Open door to highest point of travel. Draw an intersecting horizontal line on header wall 5cm (2") above high point to provide travel clearance for top edge of door.

INSTALL THE HEADER BRACKET – 12

A. Wall Mount: Center the bracket (2) on the vertical guideline (1)

with the bottom edge of the bracket on the horizontal line (6) (with the arrow pointing toward the ceiling).

Mark either set of bracket holes (4 or 5). Do not use the holes designated for ceiling mount. Drill 4,5mm (3/16") pilot holes and fasten the bracket with wood screws (3).

B. Ceiling Mount: Extend vertical guideline (1) onto the ceiling.

Center the bracket (2) on the vertical mark no more than 150mm (6") from the wall. Make sure the arrow is pointing toward the wall.

Mark holes designated for ceiling mount only (4). Drill 4,5mm (3/16") pilot holes and fasten the bracket with wood screws (3).

ATTACH T-RAIL TO HEADER BRACKET – 13

Position opener on garage floor below the header bracket. Use packing material to protect the cover.

Note: To enable the T-rail to clear sectional door springs, it may be necessary to lift opener onto a temporary support.

The opener must either be secured to a support or held firmly in place by another person.

Raise T-rail until cable pulley and header brackets come together. Join with clevis pin (1). Insert ring fastener (2) to secure.

POSITION THE OPENER – 14

Note: A 25mm (1") board (1) is convenient for setting an ideal door-to-T-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 T-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 – 15

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 T-rail is centered over the door. REMOVE 25mm (1") board. Operate door manually. If door hits the rail, raise header bracket.

Grease the top and underside of rail surface on which the trolley slides. A tube of grease is supplied.

ATTACH MANUAL RELEASE ROPE & HANDLE – 16

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 cord (and as specified by local code).

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

INSTALL THE LIGHT – 17

Install a 40 watt maximum light bulb (1) in the socket as shown. The light will turn on and remain lit for 4-1/2 minutes when power is connected. After 4-1/2 minutes it will turn off.
