ASSEMBLE TRACK AND OPERATOR
If possible, install the door opener 7 feet or more
above floor with the manual release handle
mounted 6 feet above the floor.
Check the identification tag mounted on the electrical
box to be sure the voltage, phase and h.p. are correct
for your needs.
1.Fasten track to the operator frame. DO NOT
TIGHTEN BOLTS. See Figure 1.
2. Position the trolley on the track. Attach track
spacer(s).
3. Place idler shaft bracket over end of track. There
are two holes on each side of bracket (Fig. 1).
Fasten shaft bracket to end of rail assembly.
4. Align track so that trolley moves easily and does
not bind. Tighten all bolts.
5. Run chain around front and rear sprockets and
attach to trolley assembly with master links. Adjust
chain only until excessive slack is removed. To
retain proper tension, tighten 3/8" lock nut.

FOR METAL BUILDINGS ONLY: A strong mounting
surface for the operator front header bracket is
needed. On the wall above the center stile, weld or
bolt a 2"x2"x1/4" piece of angle iron or another
suitable, heavy-duty material as shown in Figure 2.
6. Draw a vertical line on header (or reinforcement
material) above center stile of door.
7.Raise the door to its high arc point. Use a
carpenter's level to locate high arc point on wall
above door center stile as shown in Figure 3. Make
a horizontal line, intersecting the vertical centerline
mark.
8.Close the door and refer to Figure 4. Position
operator chassis on the floor with the bottom edge of
header bracket 2" above horizontal mark and
centered on vertical line. Mark mounting holes.
FOR METAL BUILDINGS: Drill 3/8" holes for fastening
bolts. FOR CONCRETE BUILDINGS: Drill 3/8" holes
for anchor bolts, following manufacturer's instructions.
NOTE: Be sure header bracket is level before
tightening the bolts.
INSTALL OPERATOR
CAUTION: AT LEAST TWO PERSONS AND A STRONG, SAFE WORKING PLATFORM ARE
REQUIRED FOR THE INSTALLATION OF OPERATOR.

trolley travel. Press the STOP button.
If trolley did not move in the correct direction, check
for improper wiring at control station or between
opener and control station.
If the operator is three phase and control station
wiring is correct, exchange any two of the three
incoming power leads.
CONNECT DOOR ARM AND BRACKET
14. With door CLOSED, snap door arm onto operator
trolley. Position door bracket against reinforced
center stile of top section of door. Make sure arm is
straight and centered on stile. Mark bracket holes.
Drill and fasten with 5/16" bolts.
NOTE 1: Choose a set of holes which aligns door
arm in a near vertical position.
NOTE 2: If door strut interferes with placement of
door bracket, position bracket below strut. DO NOT
CUT OR MODIFY STRUT.
Attach door arm to door bracket using 3/8"-16x1" screw
and lock nut.
WARNING
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.
CAUTION
TO AVOID DAMAGE TO DOOR AND OPERATOR,
MAKE ALL DOOR LOCKS INOPERATIVE. SECURE
LOCK(S) IN "OPEN" POSITION.
IF THE DOOR LOCK NEEDS TO REMAIN
FUNCTIONAL, INSTALL AN INTERLOCK SWITCH.
WARNING
INSTALL THE CONTROL STATION WHERE THE
DOOR IS VISIBLE, BUT AWAY FROM THE DOOR AND
ITS HARDWARE. IF CONTROL STATION CANNOT BE
INSTALLED WHERE DOOR IS VISIBLE, OR IF ANY
DEVICE OTHER THAN THE CONTROL STATION IS
USED TO ACTIVATE THE DOOR,
A REVERSING
EDGE MUST BE INSTALLED ON THE BOTTOM OF
THE DOOR.
FAILURE TO INSTALL A REVERSING
EDGE UNDER THESE CIRCUMSTANCES MAY
RESULT IN SERIOUS INJURY OR DEATH TO
PERSONS TRAPPED BENEATH THE DOOR.
CAUTION
DO NOT ALLOW TROLLEY TO OVERRUN FRONT
IDLER SPROCKET OR RUN INTO OPERATOR HEAD.
LIMIT SWITCHES MAY NOT BE IN THE PROPER
POSITIONS. (See Limit Adjustments).
CAUTION
REINFORCE CENTER STILE WITH A VERTICAL
BRACE. USE A PIECE OF ANGLE IRON THAT WILL
SPAN THE HEIGHT OF TOP PANEL. DO NOT CUT
HORIZONTAL STRUT.
If electrical problems persist, call our Toll Free number
(1-800-528-6563) for assistance.
13. Operate push button so that the trolley moves forward
(toward close position). Press STOP button when
trolley is approximately 10" from front wall.
REFER TO MASTER WIRING DIAGRAM.

ADJUST LIMITS
MAKE SURE THE LIMIT NUTS ARE POSITIONED
BETWEEN THE LIMIT SWITCH ACTUATORS
BEFORE PROCEEDING WITH ADJUSTMENTS.
1. Depress open limit switch. The operator should
stop.
2. To increase door travel, spin nut away from
actuator. To decrease door travel, spin limit nut
toward actuator.
3. Adjust open limit nut so that door will stop in open
position with the bottom of the door even with top
of door opening.
4. Repeat Steps 1 and 2 for close cycle. Be sure
close limit actuator is engaged as door fully seats
at the floor.
If other problems persist, call our toll-free number for
assistance - 1-800-528-6563.

CONNECT REVERSING EDGE DEVICE (OPTIONAL)
The operator has been pre-wired to accept
connection of a reversing edge device (Figure 5,
Page 5). Connect the normally open contacts to
terminals T4 and T8 on the low voltage terminal
block. A cut-off switch will de-activate the safety
device during the last few inches of the door's
downward travel.
✳ Use SAE 30 Oil (Never use grease or silicone spray).
✔Repeat ALL procedures.
■ Do not lubricate motor. Motor bearings are rated for continuous operation.
■Do not lubricate clutch or V-belt.
■Inspect and service whenever a malfunction is observed or suspected.
■CAUTION: BEFORE SERVICING, ALWAYS DISCONNECT OPERATOR FROM POWER SUPPLY.
