4

Slip the lower insulating washer over the lower electrode assembly post, followed by the lower
insulating tube.

5

Slip the lower electrode adapter block over the lower insulating tube. Secure the lower
electrode adapter

block on the lower electrode post by tightening the lower electrode adapter

block securing screw.

6

Insert one finger into the lower electrode post mounting hole in the support base until you feel
the plug screw. Turn the plug screw counter-clockwise until it no longer protrudes from the
mounting hole.
