With the exception of placing  gaskets on both sides of the aluminum
centerpiece, there is basically no difference in assembling a cell with
either the epon-charcoal or aluminum centerpieces.  As in assembling any
cell, the windows must be correctly inserted into the window holders;
otherwise, torquing the cell will crack the misaligned windows.  Also,
there is no need to over torque the cell because of the aluminum
centerpiece or higher speeds.  Hope these suggestions are helpful
