ASSEMBLY

ASSEMBLE THE OPERATOR

The wall or mounting surface MUST provide adequate support for
the operator.
The surface must:
a. Be rigid to prevent play between the operator and the 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.
1
Select right (R) or left (L) handing.
On models J and GH operators the drive sprocket can be mounted
on either the right or left side.
For models H and HJ with manual hand chain systems, the
handing of the operator must be determined at the time of order.
The handing is indicated by the last letter of the model number
(R or L). If the position of the operator causes the hand chain to
hang in the door opening hook the chain to the side near the top of
the door jamb.
2
Place the operator drive sprocket on the appropriate side of the
operator for your installation type. To avoid potential damage
caused by an overhung load, position the sprocket as close to
the center of the exposed drive shaft.

The operator may be mounted on the wall, shelf or bracket (not

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 an Authorized Service Technician 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,
cable, 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.
• Fasten the operator SECURELY to structural supports of the
building.
• Concrete anchors MUST be used if installing ANY brackets.
