PREPARATION
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 5-1/2" (13.97 cm) between frames.
Both J and H series operators have dual output shafts and may
be mounted on either the right (standard) or left side of door, and
in either a vertical (standard) or horizontal mounting position. If
you need to move the drive sprocket, loosen BOTH set screws,
remove the sprocket and key, and place on the opposite side of
the drive shaft. Be sure to tighten BOTH set screws securely.
HAND CHAIN HANDING
For models H and HJ with manual hoist hand chain systems, the
handing of the operator must be determined at the time of order.
The handing is indicated by last letter of the model name
(R or L). The hand chain wheel can not be switched on site. If
your installation causes the hand chain to hang in the door
opening, hook the chain off to the side near the top of the door
jamb.
To prevent possible SERIOUS INJURY or DEATH:
• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an
interlock switch.
• ALWAYS call a trained professional door serviceman if door
binds, sticks or is out of balance. An unbalanced door may
not reverse when required.
• NEVER try to loosen, move or adjust doors, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension and can cause SERIOUS PERSONAL
INJURY.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.

IMPORTANT NOTE: Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The operator
may be wall mounted or mounted on a bracket or shelf. If necessary, refer to the preparation on page 5. Refer to the illustrations and
instructions below that suit your application.
MOUNT THE OPERATOR
1. Wall Mounting: The operator should generally be installed
below the door shaft, and as close to the door as possible
(Figure 1).
Bracket Shelf Mounting: The operator may be mounted either
above or below the door shaft (Figure 2).
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.
NOTE: The optimum distance between the door shaft and
operator drive shaft is between 12-15" (30.5-38.1 cm).
2. Place door sprocket on the door shaft. Do not insert the key
at this time.
3. Place drive sprocket on the appropriate side of the operator.
Do not insert the key at this time.
4. Wrap drive chain around door sprocket and join roller chain
ends together with master link.
5. Raise operator to approximate mounting position and position
chain over operator sprocket.
6. 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.
7. Align sprockets and secure (Figure 3).
8. Install Hand Chain (Models H and HJ only)
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 2' (.61 m) above the floor.

BRAKE ADJUSTMENT
A solenoid brake is available as an option (not included as a
standard feature). The brake is adjusted at the factory and should
not need additional adjustment for the the life of the brake
assembly.
Replace brake assembly when necessary. Refer to the illustration
for identification of components for the solenoid type brake
system.
CLUTCH ADJUSTMENT AND
AUXILIARY REVERSAL SYSTEM
The Auxiliary Reversal System is designed to protect the door
and motorized operator. It is NOT a substitute for a safety sensing
device. The Auxiliary Reversal System works in tandem with the
adjustable clutch to detect if a closing door runs into or comes
across an obstruction. If an obstruction is met and causes the
clutch to slip, the Auxiliary Reversal System will return the door
to the full open position when closing or stops the door when
opening.
1. Remove cotterpin from nut on the clutch shaft.
2. Back off clutch nut until there is very little tension on the
clutch spring.
3. Tighten clutch nut gradually until there is just enough tension
to permit the operator to move the door smoothly but to allow
the clutch to slip if the door is obstructed. When the clutch is
properly adjusted, it should generally be possible to stop the
door by hand during travel.
4. Reinstall cotterpin.

CONTROL WIRING
DETERMINE WIRING TYPE
Refer to the wiring diagram located on the inside cover the
electrical box to determine the type of control wiring.
STANDARD C2 OR B2 WIRING
Standard operators are shipped from the factory with jumper set
for C2 wiring, which requires constant pressure on button to
close the door. If momentary contact on close direction is desired
(B2 wiring) you must include an entrapment protection device.
See close control jumper setting below.
CONSTANT PRESSURE ON CLOSE (C2 WIRING)
Red jumper wire was placed on terminal #2 in electrical
enclosure. The operator will require constant pressure on close
control in order to keep door moving in the close direction.
MOMENTARY CONTACT ON CLOSE (B2 WIRING)
Move red jumper wire from terminal #2 to terminal #3. The
operator will require only momentary contact to close the door.
SPECIAL CONTROL WIRING
If your operator was shipped from the factory with non-standard
control wiring or with optional accessories that require addition
instructions, refer to the wiring diagram(s) indicated in the
special control wiring data box. When a replacement wiring
diagram is present, wiring diagrams in this manual will not apply.
Refer only to the replacement wiring diagram for all connections.
RADIO CONTROLS
On all models with type B2 control wiring, a terminal bracket
marked R1 R2 R3 is located on the outside of the electrical
enclosure. All standard radio control receivers (single channel
residential type) may be mounted to this bracket. The operator
will then open a fully closed door, close a fully open door, and
reverse a closing door from the radio transmitter. However,
for complete door control from a transmitter, a commercial
three-channel radio set (with connections for Open/Close/Stop)
is recommended.
ADDITIONAL ACCESS CONTROL EQUIPMENT
Locate any additional access control equipment as desired (but
so that the door will be in clear sight of the person operating the
equipment), and connect to the terminal block in the electrical
enclosure as shown on the Field Wiring Connections diagram.
Any control with a normally (N.O.) isolated output contact may be
connected in parallel with the OPEN button. More than one device
may be connected in this manner. Use 16 gauge wire or larger for
all controls. Do not use the Control Circuit Transformer (24Vac) in
the Operator to power any access control equipment other than a
standard residential type radio receiver.
EXTERNAL INTERLOCK SWITCH
The operator has a terminal connection for an external interlock
switch. This switch must be a normally closed (N.C.) two-wire
device with a contact rating of at least 3 amps at 24Vac. When
such a switch is connected as shown on the Field Wiring
Connections diagram, the control circuit will be disabled when the
switch is actuated, thereby preventing electrical operation of the
door from the control devices.
To prevent possible SERIOUS INJURY or DEATH, install
reversing sensors when the 3-button control station is out of
sight of the door or ANY other control (automatic or manual) is
used. Reversing devices are recommended for ALL installations.
