LIFT-MASTER PRO8000 Instructions page 20

ATTACH RAIL TO HEADER BRACKET
Position opener on garage floor below the header bracket. Use
packing material to protect the cover.
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.
Raise rail until rail brackets and header bracket come together. Join
with clevis pin (1). Insert ring fastener (2) to secure.
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 trolley from the belt. The trolley can remain
disconnected until connecting door arm to trolley is completed.
HANG THE OPENER 12
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 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 through hole in top of red handle so
"NOTICE" reads right side up as shown (1). Secure with an overhand
knot (2). Knot should be at least 25mm (1") from end of the rope to
prevent slipping.
A. C-rail: Thread other end of rope through hole in release stop of
plastic trolley (3), then through hole in metal release lever (4).
B. T-rail: Thread the other end of the rope through the hole in the
release arm (3) of the outer trolley.
Adjust rope length so that handle is 1,8m above the floor. Secure with
an overhand knot. 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 (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 right side panel of
the opener. Connect the bell wire to the screws as follows: white/red
to 1 and white to 2. For 27 MHz models, make sure the antenna
wire (8) is fully extended, at least 60cm (2 feet) away from existing
wiring.
OPERATION OF THE LIGHTED DOOR CONTROL BUTTON
Press to open or close the door. Press again to reverse the door
during the closing cycle or to stop the door during opening cycle.
INSTALL THE LIGHTS AND LENSES
Install a 40 watt maximum light bulb (bulbs not included) in each
socket (1). The lights will turn on and remain lit for 4-1/2 minutes when
power is connected. After 4-1/2 minutes they will turn off.
Replaced burned out bulbs with rough service light bulbs.
Apply slight pressure on the sides of each lens (2) and slide the tabs
(3) into the slots (4) in the side panels. Reverse the procedure to
remove the lenses. For convenience, the lenses may be installed
after Adjustment Step 21.
FASTEN DOOR BRACKET
If yours is a canopy or dual-track style 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.
