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.

INSTALLATION

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.

9. Mount Chain Keeper / Keyhole Bracket

Using suitable hardware mount the chain keeper

approximately 4' (1.22 m) 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.

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.

POWER WIRING CONNECTIONS

To reduce the risk of SEVERE INJURY or DEATH:

• ANY maintenance to the operator or in the area near the

operator MUST NOT be performed until disconnecting the

electrical power and locking-out the power via the operator

power switch. Upon completion of maintenance the area MUST

be cleared and secured, at that time the unit may be returned

to service.

• Disconnect power at the fuse box BEFORE proceeding.

Operator MUST be properly grounded and connected in

accordance with local electrical codes. The operator should be

on a separate fused line of adequate capacity.

• ALL electrical connections MUST be made by a qualified

individual.

• DO NOT install ANY wiring or attempt to run the operator

without consulting the wiring diagram. We recommend that

you install an optional reversing edge BEFORE proceeding with

the control station installation.

• ALL power wiring should be on a dedicated circuit and well

protected. The location of the power disconnect should be

visible and clearly labeled.
