Preparing the Covers
Wash the covers and scrub around the under edge to remove all dust. After they are thoroughly dry place them upside down on a bench.
Melt the sealing compound and pour it around the outer edge to make a fillet in the groove.
Assembling the Element and Separators
Place the plates of a positive group between the plates of a negative group and lay the element thus formed on its edge, as shown in Fig. 329.
Next insert a wood separator between each of the positive and negative plates.
Next insert the hard rubber rods through the holes in the lugs of the end negative plates, and screw on the nuts. Do not screw the nuts so tight as to make the plates bulge out at the center. The rod should project the same amount on each side of the element.
Place the element in a vertical position.
