Installation Instructions

IMPORTANT INSTALLATION INSTR CTIONS

WARNING

TO REDUCE THE RI K OF EVERE INJURY OR

DEATH TO PER ON :

1. READ AND FOLLOW ALL IN TALLATION IN TRUCTION .

2. Install only on a properly operating and balanced door. A door that is operating

improperly could cause severe injury. Have qualified service personnel make repairs

to cables, spring assemblies and other hardware before installing the operator.

3. Remove all pull ropes and remove, or make inoperative, all locks (unless

mechanically and/or electrically interlocked to the power unit) that are connected to

the door before installing the operator.

4. Installation of this door operator must be done by a qualified installer.

5. Verify that the operator is correct for type, size of door and frequency of use per the

operator specifications.

6. Install the door operator at least 8 feet (2,44 m) or more above the floor if the operator

has exposed moving parts. Covers or guarding, provided by the manufacturer, must

be installed when the operator is mounted less than 8 feet (2,44 m) above the floor.

7. Do not connect the door operator to the source of power until instructed to do so.

8. Locate the control station: (a) within sight of the door, (b) at a minimum height of

5 feet (1,5 m) above floors, landings, steps or any other adjacent walking surface so

small children cannot reach it, and (c) away from all moving parts of the door.

9. Install the Entrapment Warning Placard next to the control station in a prominent

location.

10. For products having a manual release, instruct the end user on the operation of the

manual release.

11. If you have any questions about the safety of the door operating system, do not install

the operator, contact Manaras-Opera at 1-800-361-2260.

3 Operator Installation

3.1 Operator Mounting Options

The heavy-duty jackshaft operator line has a dual output shaft and may be wall mounted on either the left hand side

or the right hand side of a sectional door or a rolling door. The heavy-duty jackshaft hoist model comes with a chain

hoist located on the right of the operator. If the application requires that the chain hoist be located on the left of the

operator, it may easily be moved in the field, per the instructions found in section 4, p.10.

This operator is not intended to be installed on horizontal slide doors.

Figure - Right Side or Left Side Wall Mount

(Chain Hoist on Right)

Figure 6 - Right Side Wall Mount

(Chain Hoist on Right)

3.2 Operator Mounting Holes

CA TION

The operator has exposed moving parts and to prevent access to the pinch points, this operator must be installed

at least 8 feet (2,44 m) or more above the floor. Alternatively, covers or guarding, provided by the manufacturer,

must be installed when the operator is mounted less than 8 feet (2,44 m) above the floor.

1. Ensure that the wall or mounting surface provides adequate

support for the operator. The surface must be rigid enough to

prevent any play between the operator and the door shaft.

2. Locate the four mounting holes and the two positive locking

holes, as shown in Figure 7.

3. The optimum distance between the door shaft and the

operator drive shaft is between 12" and 15".

4. ecure the operator to the wall with 1/2” thru-bolts. If the wall

construction prohibits the use of thru-bolts, then sufficiently

sized lag bolts and anchors may be used.

5. Only tighten the bolts after having adjusted the tension of the

drive chain.

6. Ensure that the door shaft and the operator shaft are

parallel.

7. Adjust the drive chain as per instructions found in section

3.3, p.8.

8. ecure the positive locking holes with 1/2” thru-bolts in order

to prevent the operator from moving during the operation,

which keeps the drive chain alignment straight and avoids

abusive wear to the sprockets. Figure 7 - MGH Mounting Holes

Holes

3.3 Sprockets, Spreader Bar and Drive Chain Installation

The hardware components shown in Figure 8 have been supplied with your operator.

1. Place the door sprocket loosely on the door shaft.

2. Place the operator drive sprocket on the appropriate side of the operator and align it with the drive sprocket of

the operator.

3. Lock the operator and door sprockets in place by inserting the keys and tightening their respective set

screws.

4. Wrap the operator drive chain around the door sprocket and the operator sprocket. horten the drive chain to

the appropriate length. Use the chain link to attach the operator drive chain together.

5. lide the operator to tighten the drive chain and then firmly tighten the mounting bolts.

6. Check the tension on the chain (there should be no more than a 1/4" of slack when the chain is depressed

between the sprockets).

7. Manaras-Opera recommends the use of a chain spreader (sold separately).

3.3.1 Gear Reducer Breather

CA TION

• To avoid the risk of having high pressure build-up in the reducer (gear box), a reducer breather should

be installed.

•Failure to install the breather may lead to oil leakage from the seal, which will damage the reducer.

All Gear Head operators are supplied with a Reducer Breather. The breather is not mounted at the factory in order to

avoid leakage during handling of the reducer.

For technical support, please call 1-800-361-2260 or visit www.manaras.com for more information

4 Manual Hand Chain and Disconnect Chain

4.1 Adjustment of the Manual Hand Chain

By default, the operator is provided with the chain hoist located on the right hand side. If handling requires the chain

hoist to be on the left side (rolling doors, left operator hood mount), the hoist can easily be transferred from the right

hand side to the left hand side in the field. Refer to Figure 9 and step by step instructions below.

1. Use an Allen key to unscrew and remove the collar.

2. Remove the washer which is located between the collar and the chain guide.

3. Remove the chain guide.

4. Remove the pocket wheel.

5. Transfer these components to the left hand side.

6. Insert the pocket wheel on the hoist shaft up against the spring pin.

7. Insert the chain guide on the hoist shaft.

8. Insert the washer against the chain guide.

9. Insert the collar at the end and use an Allen key to tighten the set screw.
