13.5 DISASSEMBLING THE GROUND STACK
Disassembling a ground-stacked A12 system is similar to assembling a stack, only in reverse. Follow the instructions below to safely
disassemble the array.
STEPS:
• If more than four A12 cabinets are used, disconnect and remove the additional A12 cabinets from the stack until only four A12
cabinets remain on the VT.
• Reset all A12 cabinets to the 10° STORAGE position, working from the top cabinet in the array to the bottom on one side, then
doing the same on the other side. Lift each cabinet by its rear handle, then press the Lock Release button to release the red
Angle Lock mechanism and allow the cabinet to return to the STORAGE position.
• Remove the LOCK ANGLE quick release pins on the A12 VT GND and carefully lower the A12 stack to the level, -15° position.
• Move both the SET ANGLE and LOCK ANGLE quick release pins to the STORAGE positions.
• Lower the stack to the ground by turning the four screw jacks counterclockwise until they reach their furthest position.
• Remove the QRPs that connect the ground stack to the Vertical Transport cart. Remove the VT GND from under the Vertical
Transport cart by sliding the skates to the side of the VT. Replace the two QRPs to the connecting positions.
