IMPORTANT NOTE: Before the operator is installed, be sure the door has been properly aligned and is workingsmoothly. Although each installation will vary due to particular building characteristics, refer to the followinggeneral procedures to install the operator.

MOUNT HEADER BRACKETThe trolley operator is generally mounted over thecenter of the door. However, off center mountingmay be required due to interfering structures orlocation of door stile / top section support. In suchcases, the operator may be mounted up to 24” offcenter on torsion spring doors. Extension springsrequire center mounting.

1. Locate the center of the door and mark a line onthe wall directly above the door. Extend this line upthe wall.

2. Determine the highest point of door travel.Slowly raise the door and observe the action of thetop section. When the top section reaches its highestpoint, use a level and project a line from this point tothe center line the of the door.

MOUNT OPERATOR1. Allowing the motor to rest on the floor, raise thefront end of the track assembly to the front headerbracket and fasten using the 3/8”dia. x 6.40” longpivot shaft and cotterpins supplied.

3. Using the projected lines for location, mount asuitable wood block or length of angle iron to the wallabove the door opening. Refer to the illustrationbelow. This will provide a mounting pad for the frontheader bracket of the operator. If necessaryreinforce the wall with suitable mounting brackets toensure adequate support of mounting pad. Usingsuitable hardware, mount the (U shaped) front headerbracket to the pad.

Header Bracket Drill Pattern

2. Swing the operator to a horizontal position abovethe guide rails and temporarily secure with a suitablerope, chain, or support from the floor. Now opengarage door slowly, being careful not to dislodge thetemporary support. Using the door as a support,place a level against the rail and shim the operatoruntil it is horizontal. Make sure that the operator isaligned with the center line of the door.

INSTALLATION INSTRUCTIONS

OPERATOR SUPPORT1. The illustration below shows a typical method ofhanging the operator from the ceil ing. Eachinstallation may vary, but in all cases side bracesshould be used for additional strength.

2. For mounting of the support brace(s) to thepowerhead, Four holes (clearance up to 3/8” bolts)are located on each side of frame.

NOTE: If the operator is longer than 15 feet, use of amid-span support is recommended.

STRAIGHT ARM ATTACHMENT1. Fully close the door and move the trolley slider towithin (2”) two inches of the front idler.

2. Latch the straight door arm to the fixed roll pin inthe trolley carriage. Make sure the open side ofnotch on the arm faces the doorway.

3. Attach the door bracket to the door arm using the3/8”-16 x 1” bolt and nylon locking nut provided.Leave the nut and bolt loose enough to allow the twopieces to pivot freely.

4. Using 3/8” hardware provided, bolt the curveddoor arm to the straight arm, aligning the mountingholes in such a way that the door bracket pivot boltwill be in line with the top rollers on the door.

5. Position the door bracket to the center line on thedoor. Using suitable hardware, attach the doorbracket to the door. Many installations, except solidwood doors, will require additional support for thedoor. Refer to the illustration below.

IMPORTANT NOTE: At this time, ensure all boltsand lag screws are properly secured.

FAILURE TO SUSPEND THE OPERATORSECURELY MAY RESULT IN SERIOUS PERSONALINJURY OR DEATH, AND/OR PROPERTY DAMAGE.
