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 TENSION AND CAN CAUSE SERIOUS PERSONAL INJURY. CALL A PROFESSIONAL DOOR SERVICEMAN TO MOVE OR ADJUST DOOR SPRINGS OR HARDWARE.

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.

Relocate bracket using existing hardware.

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 cable sheave bracket (Figure 5) before proceeding with the cable assembly installation.

ADJUST LIMITS

WARNING

TO AVOID SERIOUS PERSONAL INJURY OR DEATH FROM ELECTROCUTION, DISCONNECT ELECTRIC 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.
