User manual LIFT-MASTER GSD

[. . . ] Single doors over 14' or Bi-Part doors over 8' will require additional wall brackets, refer to chart. 3 OPERATOR ASSEMBLY The slide door operator should be pre-assembled as follows before installation: 1. Layout the two pieces of track on the floor, parallel to each other and install end idler shaft assembly (see page 5). The holes in the track for the hangars are pre-punched and are generally about 5 feet apart. Install chain take-up bolt on slider carriage with two 3/8 hex nuts and lockwasher and slide the slider carriage onto the track so that the take-up bolt will be facing the powerhead (see page 5). [. . . ] This dimension must be less than 4 inches, it may be necessary to shim the brackets out from the wall accordingly. With the door fully closed, locate the vertical center-line of the door and mark this line on the wall above the door. Measure 18" to the left of this line if the door slides left to close or 18" to the right of this line if the door slides right to close (see figure 1). The track should extend 3-1/2 feet beyond the door opening (see figure 2). Set the assembled operator into position and mark the holes for the angle mounting brackets on the wall, as low as possible without interfering with door travel (see figure 6). If wall construction does not permit the use of throughbolts, lag bolts and shields may be used. Adjust the track hangers on the mounting brackets to the desired position and tighten all bolts. It is recommended that at least one sway brace be used (not provided) between the wall and one of the track hangers for increased rigidity, especially on large or heavy doors. Mount the door disconnect mechanism on the center-line of the door so that the top of the bracket is no more than 1-1/2" below the slider carriage (see figure 6). This mechanism may be adjusted both front to back and up and down to align the disconnect pin. It may be necessary to shim between the mechanism and the door to bring the pin out into the center-line of the track. NOTE: For bi-parting doors, mount each door disconnect mechanism centered on a line 24" from the door edge (see figure 2). Move the door so that the disconnect pin is directly aligned with the hole in the carriage and engage pin in hole. FIGURE 6 4" MAX. SLIDER CARRIAGE POWER HEAD CLEARANCE FROM WALL ANGLE BRACKETS SHOULD NOT INTERFERE WITH DOOR TRAVEL BOTTOM OF TRACK 6-1/4" MAX. TOP OF DOOR 1-1/2" MIN. DOOR DISCONNECT MECHANISM SCREW COLLAR 6 NOTE: For bi-parting doors, it is necessary to bring the doors to a fully closed position for proper synchronization. With both disconnect pins and engaged in their respective carriages, lift the drive chain over the three studs on the bi-part carriage and secure the chain to the slider with the hardware provided (see figure 5). 7. Adjust the screw collars on the disconnect pin so that it enters into the trolley bracket about 3/4". Mount the chain retaining bracket (with keyhole slot) at a convenient height on the door, directly below and aligned with disconnect chain. [. . . ] Be sure that one is lower than the other so as not to interfere with each other when the doors are fully closed. IMPORTANT: TEST THE FUSIBLE LINK DISCONNECT INSTALLATION AS FOLLOWS: Manually remove the fusible link from the bracket and allow the weight to pull down on the disconnect pin. If necessary, adjust spring on disconnect assembly by moving top shaft collar up or down. ELECTRICAL CONNECTIONS & OPERATING INSTRUCTIONS POWER AND CONTROL WIRING: Refer to the Owners Manual supplied with your operator for all power and control wiring. ELECTRICAL OPERATION: The door can be operated by means of the three button control station or by other controls, when provided. [. . . ]
