Children operating or playing with a garage door operator can injure themselves or others. The garage  
door could cause serious injury or death. Do not allow children to operate the remote control(s) or  
the wall station. Install the wall station out of reach of children and away from all moving parts of  
the door. The door must be clearly visible from the wall station. A moving garage door could injure  
someone under it. Only activate the door when it is properly adjusted, when it can be seen clearly  
and when there are no obstructions to the door travel.

Ropes connected to a garage door can cause entanglement and death.  
IMPORTANT! DO NOT PLUG THE OPERATOR IN AT  
THIS TIME! More installation is required.  
If possible, install door operator 7 feet or more above the floor with the manual release handle mounted  
6 feet above the floor. Instruct the end user on the operation of the manual release.

6 Hang the Operator  
PREPARING TO HANG THE OPERATOR  
Locate the wall station within sight of the door at a minimum height of 5 feet so that small children  
cannot reach it. Locate the wall station away from all moving parts of the door.  
Residential Installations: Install the User Safety Label on the wall adjacent to the wall station.  
Commercial Installations:Install the EntrapmentWarning Placard and Duty Rating Label in a prominent  
location visible in the area of the door.  
Persons, particularly children, could be killed by  
a closing garage door without a properly installed  
and adjusted safety beam optical obstacle  
sensing system.  
To prevent electrocution or fire, installation  
and wiring must be in compliance with local  
electrical and building codes.  
To reduce the risk of electric shock, this  
operator has a grounding pin. This plug will  
only fit into a grounding type outlet. If the plug  
doesn’t fit into the outlet, contact a qualified  
electrician to install the proper outlet. Do not  
change the plug in any way.  
Installation requirements vary with garage construction.  
Hanging brackets should be angled to provide rigid  
support. Hanging material is not provided. Angle iron  
and lag screws are recommended. DO NOT USE NAILS.  
Following are typical operator hanging methods. Certain  
installations will require improvised methods.

Cord and Outlet Connection  
NOTE: The safety beam’s infrared light beam must  
not be obstructed by the door, or by any part of the  
door hardware. Use wooden spacers between the  
beam brackets and wall if necessary to create proper  
clearance.  
The operator should be connected to a grounded  
receptacle on the ceiling or near the operator head. If  
none is available which will accept the grounded operator  
plug, one should be installed by a qualified electrician. Do  
not use an extension cord.  
Upon completion of the installation, the door must reverse when it comes in contact with a 1-1/2high  
object (or a 2x4 laid flat at the center of the door) on the floor and when the infrared safety beam is  
blocked.  
1 Raise the operator head and set it on top of a  
stepladder (use extra spacers on top of ladder if it isn’t  
tall enough).  
WALL MOUNTING  
FLOOR MOUNTING  
Do not wear watches, rings or loose clothing while installing or servicing an operator. Jewelry or  
loose clothing can be caught in the mechanism of the garage door or the operator.  
MARKING THE CORRECT BEAM BRACKET HEIGHT  
2 Carefully open the door to the full up position. Lay a  
2x4 across the top section of the door as a spacer.  
Adjust the operator height until the rail touches the  
spacer. The rail should be close to level.  
1 Plug the operator into a grounded receptacle.  
1 Assemble the two safety beam brackets from the four  
L-shaped brackets using two ¼-20 x ¾” bolts and ¼-20  
keps nuts (one nut & bolt for each bracket).  
POWERING THE OPERATOR  
10 DISCONNECT THE ELECTRIC POWER FROM THE GARAGE DOOR OPERATOR BEFORE MAKING  
ANY REPAIRS OR REMOVING THE COVER.  
2 When the operator is plugged in, a click should sound  
in the operator and the lights should turn on. If the  
lights do not turn on, check the power source and light  
bulbs.  
11 Commercial Installations:The rate of operation must not exceed 13 cycles of opening and closing per  
hour.  
3 Center the operator head and rail with the centerline  
mark on the top of the door.

be required. Mark mounting hole locations, drill pilot  
holes and attach the piece with two lag screws (not  
supplied).

NOTE: The safety beam receiver (the unit with two  
indicators) should be located on the “shady” side of  
the door to prevent sunlight from shining directly into  
the receiver’s lens.  
IMPORTANT: If the garage door is unbalanced or  
the door travel isn’t smooth, have a qualified garage  
door professional adjust or repair the door.  
For unfinished ceilings: Hold each bracket in place  
and use a pencil to mark the locations where they will  
be attached to the joists, drill pilot holes and attach the  
pieces with two lag screws (not supplied).
