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.
For metal buildings, fasten 2” x 2” x 3/16” (or larger)
angle iron frames to the building purlins. Retain
2-1/4” between frames. See Figure 1.
The GJ 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.
MOUNTING CONVERSIONS
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 cotterpins.
IMPORTANT SAFETY NOTES
FIGURE 2

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”.
On concrete buildings, attach a shaft support
bracket to the wall of the building. Refer to Figure 3.
OPERATOR MOUNTING
IMPORTANT: An additional wall mounting
plate (P/N 10-9098) or equivalent is
recommended to provide additional support
and to allow for adjustment of the drive chain.
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).
Mount Door Sprocket to Door.

The standard GJ operator is setup for mounting on right side of the door and in vertical position. If necessary,
refer to the operator mounting conversions on page 3. Refer to the illustrations and instructions below that suits
your application.
Be sure door sprocket
is properly aligned with
drive sprocket before
securing to shaft.
FIGURE 5

SENSING EDGES
All types of sensing edges with an isolated normally
open (N.O.) output are compatible with your
operator. This includes pneumatic and electric
edges. If your door does not have a bottom sensing
edge and you wish to purchase one, contact the
supplier of your operator.
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. Refer to the steps below
Important Notes:
a) Proceed with Limit Switch Adjustments before
making any sensing edge wiring connections to
operator as described on page 8
b) Electrician must hardwire the junction box to the
operator electrical box in accordance with local
codes.
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. 5

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.
8. Mount Chain Keeper
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.
EMERGENCY MANUAL HOIST OPERATION
IT IS STRONGLY RECOMMENDED THAT A
SENSING EDGE OR OTHER ENTRAPMENT
PROTECTION DEVICE BE USED IN
CONJUNCTION WITH THIS OPERATOR.
a) 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 chain keeper mounted on the wall.
b) Operate the door in the desired direction by
pulling on one side or the other of the continuous
loop hoist chain (large chain).
In case of emergency or power failure, the operator has provision for manually operating the door. An electrical
interlock will disable the electrical controls when manual hoist is used. To operate the hoist:
c) The disconnect chain must be released from
chain keeper before door will operate again
electrically.

1. Complete electrical connections to the operator
and the control station. Fasten the control station
to the wall and MOUNT THE WARNING NOTICE
BESIDE OR BELOW THE PUSH BUTTON
STATION.
2. Apply power to the operator. Press OPEN push
button and observe direction of output shaft
rotation. See Figure 4, page 4. Press the STOP
button.
If shaft does not rotate in the correct direction,
check for improper wiring at the control station or
between operator and control station.
If the operator is three phase and control station
wiring is correct, exchange any two of the three
incoming power leads.
If electrical problems persist, call our Toll Free
number for assistance (1-800-528-6563).
CABLE CONNECTION NOTE:
Be sure to use the control box opening with the
1-1/16" hole for the POWER cable. All control wires
use the 7/8" hole.
Refer to Master Wiring Diagram. Make connection
through holes labeled for power and control. Do
not run control wires in the same conduit as
power wires.
Before installing control station be sure to follow all warnings described below. Failure to so may result
in severe injury to persons and/or damage to operator. Do not install any wiring or attempt to run the
operator without consulting the wiring diagram. Install the optional Reversing Edge before proceeding
with the Control Station installation.

MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE
PROCEEDING WITH ADJUSTMENTS.
1. To increase door travel, spin nut away from actuator. To decrease door travel, spin limit nut toward actuator.
2. Adjust open limit nut so that door will stop in open position with the bottom of the door even with top of door
opening.
3. Repeat Steps 1 and 2 for close cycle. Be sure close limit actuator is engaged as door fully seats at the floor.
