SITE PREPARATIONS
It is imperative that the wall or mounting surface provide adequate support for the operator.
This surface must:
a) Be rigid to prevent play between operator and
door shaft.
b) Provide a level base.
c) Permit the operator to be fastened securely and
with the drive shaft parallel to the door shaft.
The safety and wear of the operator will be adversely
affected if any of the above requirements are not met.
OPERATOR PREPARATION
IMPORTANT SAFETY NOTES
5-1/2”
The GH operator may be mounted on either the right (standard) or left side of door, and in either a vertical (standard) or horizontal mounting position. Refer to the steps below if you require the hand chain and/or disconnect
chain to be on the opposite side of the operator; Or if the operator is being mounted in a horizontal position.
Hand Chain Right/Left Conversion
Remove the two snap rings (1 pc. outer, 1 pc inner) on
hand chain shaft assembly. Position roll-pin to fit
through cutout in frame and slide complete shaft
assembly through housing and bevel gear. Insert shaft
assembly on opposite side of housing, and replace
bevel gear, bearing, hardware, and snap rings on the
opposite side of shaft in the same manner.
Disconnect Lever Right/Left Conversion
Remove cotter pins on the ends of the disconnect
shaft (square shaft), move the disconnect lever arm to
the opposite side, and replace the cotter pins. Be sure
to keep two(2) 12ga. washers on the side without the
lever arm.
Horizontal Mounting Conversion
Remove cotter pins on the ends of the disconnect
shaft (square shaft), and remove lever. Replace lever
using square hole on opposite end of lever. Reposition
sash chain to opposite end of lever also. Replace cotter pins.

1a. Wall Mounting
The operator should generally be installed below
the door shaft, and as close to the door as possible. The optimum distance between the door shaft
and operator drive shaft is between 12” - 15”. Refer
to Figure 3.
OPERATOR MOUNTING
IMPORTANT: The shelf or bracket must provide adequate support, prevent play between
operator and door shaft, and permit operator
to be fastened securely and with the drive
shaft parallel to the door shaft.
1b. Bracket or Shelf Mounting
The operator may be mounted either above or
below the door shaft. The optimum distance
between the door shaft and operator drive shaft is
between 12” - 15”. Refer to Figure 4.
1c. Place door sprocket on the door shaft. Do not
insert the key at this time.
2. Place drive sprocket on the appropriate side of the
operator. Do not insert the key at this time.
3. Wrap drive chain around door sprocket and join
roller chain ends together with master link.
4. Raise operator to approximate mounting position
and position chain over operator sprocket.
5. Raise or lower operator until the chain is taut (not
tight). Make sure the operator output shaft is parallel to door shaft and sprockets are aligned. When
in position, secure the operator to wall or mounting
bracket.
6. Align sprockets and secure, (see Figure 5).

These operators are equipped with a manual hoist. An
electrical interlock will disable the electrical controls
when the hoist is used.
To operate the hoist:
1. Pull the disconnect chain (small chain) to engage
the hoist mechanism. The disconnect chain may be
locked in position by slipping the end through the keyhole of the chain keeper mounted on the wall.
2. Operate the door in the desired direction by pulling
on one side or the other of the continuous loop hoist
chain (large chain).
3. The disconnect chain must be released from the
chain keeper before the door will operate again electrically.
7. Install Hand Chain
Place hand chain around hand chain wheel. Be
sure to pass it through both openings in the chain
guide. Remove enough links so chain hangs approximately two feet above the floor
EMERGENCY MANUAL OPERATION
This operator has provisions for manually operating the door in case of emergency or power failure. Refer to the
appropriate instructions below for your model operator.

8. Mount Chain Keeper / Keyhole Bracket
Using suitable hardware mount the chain keeper
approximately 4 feet above the floor, near the free
hanging chain. Remove disconnect sash chain
from bag and place the end through the keyhole in
the the chain keeper. Remove excess links if necessary.
TURN OFF POWER TO THE OPERATOR BEFORE
MANUALLY OPERATING YOUR DOOR.

LIMIT SWITCH ADJUSTMENT
MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE
PROCEEDING WITH ADJUSTMENTS.
If other problems persist, call our toll-free number for
assistance - 1-800-528-2806.
1. To adjust limit nuts depress retaining plate to allow
nut to spin freely. After adjustment, release plate
and ensure it seats fully in slots of both nuts.
2. To increase door travel, spin nut away from actu-
ator. To decrease door travel, spin limit nut toward
actuator.
3. Adjust open limit nut so that door will stop in open
position with the bottom of the door even with top
of door opening.
4. Repeat Steps 1 and 2 for close cycle. Adjust close
limit nut so that actuator is engaged as door fully
seats at the floor.
PHOTO EYES & SENSING EDGES
Sensing devices supplied for door industry type operators
with an isolated normally open (N.O.) dry contact output
are compatible with your operator. This includes through
beam and retro reflective photo eyes, and pneumatic and
electric edges. If your door does not have bottom safety
photo eyes or a sensing edge and you wish to add a safety device to your application, please contact your local
LiftMaster Authorized Dealer.
If not pre-installed by the door manufacturer, mount the
sensing edge on the door according to the instructions provided with the edge. The sensing edge may be electrically connected by either coiled cord or take-up reel.
Important Notes:
a) Proceed with Limit Switch Adjustments before making
any sensing edge wiring connections to operator as
described below.
b) Electrician must hardwire the junction box to the oper-
ator electrical box in accordance with local codes.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL) CONT’D
WIRING: For wiring of your sensing device to the
operator, refer to the wiring diagram on pages 11-13.
See field connection terminals identified as
Reversing Device.
TAKE-UP REEL: Take-up reel should be installed 12"
above the top of the door.
COIL CORD: Connect operator end of coil cord to
junction box (not supplied) fastened to the wall
approximately halfway up the door opening.
IT IS STRONGLY RECOMMENDED THAT A
SAFETY PHOTO EYE OR SENSING EDGE BE
USED IN CONJUNCTION WITH THE OPERATOR.

On all models with B2 control wiring, a terminal bracket
marked R1 R2 R3 is located on the outside of the electrical enclosure. Any commercial type LiftMaster brand
receiver may be mounted to this bracket. The operator
will then open a fully closed door, close a fully open
door, stop an opening door, and reverse a closing door
from the radio transmitter. In TS control wiring the operator will only open the door or reset the timer to close.
However, for additional door control from a 3 button
transmitter, a commercial three-channel radio receiver
(with connections for OPEN/CLOSE/STOP) is recommended.
2. Be sure to run all control wires through the conduit
hole in the electrical box enclosure marked with the label
shown below.
3. Apply power to the operator. Press OPEN push button
