INSTALL OPERATOR
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.
DO NOT CONNECT ELECTRIC POWER UNTIL
INSTRUCTED TO DO SO.
FOR SECTIONAL AND ROLLING TYPE DOORS
CAUTION: AT LEAST 2 PERSONS AND A SAFE
WORKING PLATFORM ARE REQUIRED FOR
INSTALLATION.
Check the operator name plate mounted on the
electrical box to be sure the voltage, phase and h.p.
are correct for your needs.
1. Close door.
2. For metal buildings, fasten 2"x2"x3/16" (or larger)
angle iron frames to the building purlins. Retain
2-1/4" between frames. See Figure 1.
3. Place door sprocket and shaft support bracket
(sectional door only) on door shaft as shown.
Attach shaft support bracket to angle brace.
On concrete buildings, attach shaft support bracket
to wall of building.
NOTE 1: On concrete or block walls, install the
operator as shown in Figure 2.
NOTE 2: For standard rolling steel doors, install
operator as shown in Figure 3. (If mounting to a
steel building, make an angle iron mounting
frame as shown in Figure 1.)
WARNING
KEEP DOOR BALANCED. STICKING OR BINDING
DOORS MUST BE REPAIRED. DOORS, DOOR
SPRINGS, CABLES, PULLEYS, BRACKETS AND
THEIR HARDWARE MAY BE UNDER EXTREME

4. Place drive sprocket on the appropriate side of
the operator. Do not insert the key at this time.
5. Join roller chain ends together with master link.
6. Raise operator to approximate mounting position
and position chain over door and operator
sprockets.
7. Raise or lower operator until the chain is taut (not
tight). Make sure the operator output shaft is
parallel to door shaft and sprockets are aligned.
When in position, secure the operator to wall or
mounting bracket.
8. Hand chain wheel is factory installed. To change
position to opposite side of operator, remove Ering, chain guide, hand chain wheel and re-install
on operator in reverse order of disassembly.
Place hand chain around hand chain wheel. Be
sure to pass it through both openings in the chain
guide. Remove enough links so chain hangs
approximately two feet above the floor.

9. Uncoil emergency operating cable assembly and
mount the chain keeper bracket to the wall of the
building four feet above the floor, using two 1/4"
dia. bolts.
10. Insert cable assembly into bracket (Figure 6) and
remove slack from the cable by sliding spacer,
handle and set collar up the cable until spacer
touches underside of bracket. Temporarily tighten
set screw in set collar.
11. Remove cable assembly from bracket and slide
spacer, handle and set collar up the cable for a
distance of 3" +1/4". Permanently tighten set
screw in set collar and cut off excess cable about
1/4" from collar.
12. To engage the gears for manual hand chain
operation, pull down on handle and insert chain
keeper into bracket (Figure 6).
NOTE: To maintain proper cable tension during
manual operation, the cable assembly must be
pre-tensioned. Refer to steps 11 and 12 above.
Installation of Operator to
Standard Rolling Steel Doors.
NOTE: Vertical installations are standard, as
shown in Figures 2, 3 and 4.
For horizontal mounting applications, relocate the

POWER BEFORE MANUALLY MOVING LIMIT NUTS.
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.
