Hang The Opener - LiftMaster PRO7100 Instructions

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 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
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 chain. 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 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 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 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
Do not attempt to operate your opener until instructed during the
travel limits programming procedure. IT WILL NOT RUN. (See
Adjustment section.)
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 LIGHT AND LENS
Install a 40 watt maximum light bulb (bulbs not included) in the socket
(1). 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.
Replaced burned out bulbs with rough service light bulbs.
Apply slight pressure on the sides of the lens (2) and slide tabs (3) into
slots (4) in the end panel. Reverse the procedure to remove the lens.
Use care to avoid snapping off lens tabs.
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.
Sectional and One-Piece Door Installation Procedure:
Door bracket (1) has left and right side fastening holes. Assemble and
install the bracket and plate (2) if your installation requires top and
bottom fastening holes.
1. Center bracket (with or without plate, as required) at the top of
inside face of door as shown. Mark holes.
2. A. Wooden doors
Drill 8mm holes and fasten the door bracket with nut, lock washer,
and carriage bolt (3).
B. Sheet metal doors
Fasten with sheet metal screws (4).
C. One-piece door optional
Fasten with sheet metal screws (4).
CONNECT DOOR ARM TO TROLLEY
A. One-Piece Door Installation:
Pull the manual release handle down to disengage the trolley.
Connect straight door arm (1) and curved door arm sections (2) to
obtain nearly the longest possible length, with hardware (3, 4, 5).
With door closed, connect straight door arm section to door bracket
with a clevis pin (6). Secure with a ring fastener (7). Connect
curved arm to trolley with remaining clevis pin. Secure with ring
fastener. Last, reconnect trolley: rotate the metal release lever (see
Illustration 13, center view) and manually open the door until the
trolley engages.
B. Sectional Door Installation:
Close garage door. Pull the manual release handle down to
disengage the trolley. Slide trolley about 5cm from door. Connect
