12 Position the Header Bracket

The header bracket must be rigidly fastened to a structural support of the garage. Reinforce the wall or ceiling with a 50 mm (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 (4) on header wall 5 cm (2") above high point to provide travel clearance for top edge of door.

13 Install the Header Bracket

NOTE: Refer to vertical center and horizontal lines created in step 12 for proper placement of header bracket.

A. Wall Mount: Center the header bracket (1) on the vertical center line (2) with the bottom edge of the header bracket on the horizontal line (4) (with the arrow pointing toward the ceiling). Mark all of the header bracket holes (5). Drill 4,5 mm (3/16") pilot holes and fasten the header bracket with wood screws (3).

B. Ceiling Mount: Extend vertical center line (2) onto the ceiling. Center the header bracket (1) on the vertical mark no more than 150 mm (6") from the wall. Make sure the arrow is pointing toward the opener. Mark all of the header bracket holes (5). Drill 4,5 mm (3/16") pilot holes and fasten the header bracket with wood screws

(3). For concrete ceiling mount, use concrete anchors (6) provided.

14 Attach Rail to Header Bracket

Position opener on garage floor below the header bracket. Use packing material to protect the cover. Raise rail until holes in the header sleeve and holes in the header bracket align. Join with clevis pin (1). Insert ring fastener (2) to secure.

NOTE: To enable the 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.

15 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.

16 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 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).

17 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.

Connect Electric Power

TO AVOID INSTALLATION DIFFICULTIES, DO NOT RUN THE

3-en

GARAGE DOOR OPENER UNTIL INSTRUCTED TO DO SO.

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

18 Install Light

Gently pull lens (2) downward until the lens hinge is in the fully open position. Do not remove the lens. Install a 24V/21W maximum light bulb (1) in the socket 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.

19 Fasten Door Bracket

If you have a canopy 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. If your installation requires top and bottom fastening holes use both the door bracket and door bracket plate (2) as shown.

1.Center door bracket (with or without door bracket plate, as required) at the top inside face of door as shown. Mark holes.

A.Standard Sectional or One-piece doors: locate bracket at inside face of the door.

B.Sectional doors with two horizontal roller channels: 150 - 250mm below the top of the door.

2.A. Wooden doors

Drill 8mm holes (5/16") and fasten the door bracket with nut, lock washer, and carriage bolt (3).

B.Sheet metal doors

Fasten with wood screws (4).

C. One-piece door optional

Fasten with wood screws (4).

20 Assemble Door Arm

A. ONE-PIECE DOOR INSTALLATION:

Fasten the straight (1) and curved (2) door arm sections together to the longest possible length (with a 2 or 3 hole overlap) using hardware (3,4 and 5). With the door closed connect the straight door arm section

(1)to the door bracket with clevis pin (6). Secure with ring fastener (7). Disconnect the inner and outer trolley. Slide the outer trolley back toward the opener and join the curved arm (2) to the connector hole in the trolley (8) with clevis pin (6). It may be necessary to lift the door slightly to make the connection. Secure with ring fastener (7).

NOTE: When setting the up limit, the door should not have a “backward” slant when fully open. A slight backward slant (9) will cause unnecessary bucking and/or jerking operation as the door is bing opened or closed from the fully open position.

B. SECTIONAL DOOR INSTALLATION:

Connect according to Figure B, then proceed to Step 21.
