MOUNTING DOOR BRACKET AND ARMS
11
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 support pipe assembly with
90mm long clevis pin
(Fig. 15)
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. 16).
Mount the door bracket to the centre line of the door
(Fig. 16)
,
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. 17)
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.
