Chamberlain ML5500 Garage Door Opener User Manual


 
HANG THE OPENER
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
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
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.

connected. After 4-1/2 minutes it will turn off.
Replace burned out bulbs with rough service light bulbs (230V/W40/E27).
Apply slight pressure on sides of the lens (2) and slide tabs (3) into slots
(4) in the end panel. Reverse the procedure to remove the lens.
