Stack Module Disassembly and Re-assembly Procedure
If a requirement to disassemble and re-assemble a module stack arises, follow the following procedure.
1. Starting with the uppermost module in the stack, remove the individual cells following the
instructions shown in Appendix D.
2. Repeat until all the cells have been removed.
3. Disassemble the stack modules. Transport the bottom stack module to the desired
installation location. Mark the location of the floor anchors and install, again matching the
anchor holes in the floor-mounting base.
4. Be sure the floor mounting base or assembly is in position and level, and then torque the
floor anchors. If the base is not level, use shims to level. A level base is particularly
important for the stability and safety of these high, narrow stacks (See Figure A8).
5.
If the assembly requires additional modules, use the lifting slings. Place additional
modules, one at a time, on top of modules already in place. Properly align modules and
mounting holes, and insert the M10 bolts, washers and nuts as shown in Figures A7 and
A8. When all bolts are in place, check that assembly is plumb and level, then tighten the bolts
to 40 ft-lb (55 N-m) using a torque wrench.
6. Reinstall the cells starting with the bottom module and working up. Perform the electrical
connections last.
