MOUNTING DOOR BRACKET AND ARMS

STEP 12

With the centre point of the door located, mark a line

through the centre of the wall bracket onto the header

wall (above the door). Using the bracket as a template

mark a minimum of two holes and drill with appropriate

size bit. If necessary the wall bracket can be anchored

using more than two holes for a more secure fitting.

If the wall bracket is mounted onto concrete or brick wall,

use M8 or 5/6 loxins or dynabolts. If mounted onto

wooden lintel or beam, use wood screws #20 or

equivalent, minimum 50mm long. Attach the wall bracket

to the c- assembly with 90mm long clevis pin (Fig. 19) and

secure by snap pin.

MOUNTING DOOR BRACKET AND ARMS

STEP 13

The door bracket comes in two parts. The bottom plate

with two mounting holes is used on its own for any one

piece doors. The top plate is placed over the bottom plate

and uses 4 mounting holes for extra strength. This is used

on sectional doors. (See Fig. 20).

Mount the door bracket to the centre line of the door

(Fig. 20), using M6 or equivalent screws (not supplied)

Alternatively it can be welded on steel doors.

Note: As various types of doors exist, if in doubt about the

strength of the door, reinforcement may need to be added

to the frame of the door panel where necessary. Damage

to the door panel may occur if the bracket is installed

incorrectly on a panel with insufficient strength. The door

opener warranty does not cover damage caused by the

opener to the door and/or door panel.

STEP 14

Assemble bent and straight arm with screws, plain and

spring washer and nuts supplied in accessory pack. (Fig.

21) Then connect assembled arm to the door bracket and

the trolley by clevis pin and snap pin. Trolley must be in

disengage position. Always use both the bent and straight

arm.

If installing on a door with bad wave action, lengthening

the arm even further will assist the door operation by

reducing the wave action.
