OPERATOR PREPARATION POWERHEAD ATTACHMENT 1. Position the track assembly on the frame of the powerhead so that the motor side of operator is in back (away from door ). WARNING 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 OR DEATH. CALL A PROFESSIONAL DOOR SERVICEMAN TO MOVE OR ADJUST DOOR SPRINGS OR HARDWARE. 2.
INSTALLATION INSTRUCTIONS IMPORTANT NOTE: Before the operator is installed, be sure the door has been properly aligned and is working smoothly. Although each installation will vary due to particular building characteristics, refer to the following general procedures to install the operator. MOUNT HEADER BRACKET The trolley operator is generally mounted over the center of the door. However, off center mounting may be required due to interfering structures or location of door stile / top section support.
INSTALLATION INSTRUCTIONS STRAIGHT ARM ATTACHMENT 1. Fully close the door and move the trolley slider to within (2”) two inches of the front idler. OPERATOR SUPPORT 1. The illustration below shows a typical method of hanging the operator from the ceiling. Each installation may vary, but in all cases side braces should be used for additional strength. 2. Latch the straight door arm to the fixed roll pin in the trolley carriage. Make sure the open side of notch on the arm faces the doorway. 2.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL) PHOTO EYES & SENSING EDGES Sensing devices supplied for door industry type operators with an isolated normally open (N.O.) dry contact output are compatible with your operator. This includes pneumatic and electric edges, and through beam and retro reflective photo eyes. If your door does not have bottom safety photo eyes or a sensing edge and you wish to add a safety device to your application, please contact your local LiftMaster Authorized Dealer.
