IMPORTANT INSTALLATION SAFETY INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH TO PERSONS, REVIEW
THESE INSTALLATION SAFETY STEPS BEFORE PROCEEDING
1 READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2 Install only on a properly balanced garage door. An improperly balanced door could result in severe
injury or death. Repairs to cables, spring assemblies, and other hardware must be made by a qualified
service person before installing the operator.
3 Disable all locks and remove all ropes connected to the garage door before installing the operator.
Ropes connected to a garage door can cause entanglement and death.
4 If possible, install door operator 7 feet or more above the floor with the manual release handle
mounted 6 feet above the floor.
5 Do not connect the operator to the power source until instructed to do so.
6 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.
7 Install the User Safety Label on the wall adjacent to the wall station.
8 Upon completion of the installation, the door must reverse when it comes in contact with a 1-1/2" high
object (or a 2x4 laid flat at the center of the door) on the floor and when the infrared safety beam is
blocked.
9 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.
10 DISCONNECT THE ELECTRIC POWER FROM THE GARAGE DOOR OPERATOR BEFORE MAKING
ANY REPAIRS OR REMOVING THE COVER.
1 Check the Door Balance
CHECKING THE DOOR BALANCE
1 From outside the garage, slowly open the door all the
way, and then close it all the way. Notice if there is
any binding, sticking or rubbing. The door should move
smoothly in both directions.
2 Raise the garage door about halfway up. Carefully
release the door and see if the door balances. It should
stay in place. Close the door.
� I MPORTANT: If the garage door is unbalanced or
the door travel isn't smooth, have a qualified garage
door professional adjust or repair the door.
2 Attach the Rail to the Operator
ALIGNING THE RAIL
1 Place the operator head on the garage floor with
LINE UP THE RAIL OVER THE DRIVE SHAFT
cardboard underneath it to protect the finish. ON TOP OF THE OPERATOR HEAD
� N OTE: To prevent upsetting the pre-adjusted door
limits in the operator, keep the trolley at the same place
on the rail until the sprocket is on the drive shaft.
2 Align the rail over the center of the operator head.
3 Be sure the flat on the sprocket lines up with the flat on

2 Close the door.
3 From inside the garage, use a pencil to mark the
vertical centerline of the door on the header wall and
on the top panel of a sectional door or on the top edge
of a jamb door.
4 Examine the area above the center of the door on the
door header wall for a header bracket mounting location.
5 Open the door to the high-rise point (the point where
the top edge of the door is highest above the floor) and
measure the distance to the floor.
6 Close the door and use a pencil to mark the header
wall 1" above (sectional) or 7" above (jamb) the

measured high-rise point.
� N OTE: In some installations, the header bracket
location will be higher than the door header. This will
require adding a 2x4 (or larger) cross piece to the wall
studs to provide a mounting location for the header
bracket. Use lag screws (not supplied) to attach the
2x4 to the studs.
7 On sectional doors with low headroom, the header
bracket can be attached to the ceiling up to 6" back
from the header wall (see next step).

PREPARING TO HANG THE OPERATOR
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.
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).
2 SECTIONAL DOORS: 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.
JAMB DOORS: Carefully open the door to the high-

above the door high-rise point. The rail should angle
up towards the header wall.

beam brackets and wall if necessary to create proper
clearance.
1 Assemble the two safety beam brackets from the four
2-3/8" LONG
L-shaped brackets using two ¼-20 x ¾" bolts and
CLEVIS PIN
¼-20 keps nuts (one nut & bolt for each bracket).
WARNING
To protect small children, do not install the
safety beam higher or lower than instructed.
2 Position the assembled brackets on each side of the
door so the center line of the safety beam lenses
will be 6" above the floor. Use the index marks on
the brackets to make the bracket assemblies equal
lengths. Mark the locations for the bracket mounting
screws (the brackets can be wall or floor mounted).
� N OTE: 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.
3 Drill two 3/16" pilot holes for lag screws at marks.
Mount the brackets with two ¼" x 1-¼" lag screws and
tighten with a 7/16" socket (or use proper concrete
fasteners if floor mounting).
4 Insert the sender and receiver into the bracket holes
so the lenses of the units will face each other. Twist the
units until the spring clips lock into a detent mark on
the brackets. To protect the units from being bumped

6 For non-prewired installations, secure all the wires
to the wall and ceiling with insulated staples (not
supplied). Staples must straddle both wires to prevent
shorts. Secure the wire to the top of the rail with wire
clips (supplied).
7 At the operator, twist one wire from each pair together,
then twist the other wire from each pair together.

1 Fully close the door. Hold the door bracket against the
inside of the door's top panel. Align the top edge of the
bracket 2" to 4" below the top edge of the door; or, if
there is a structural support across the top of the door,
