figures 16 and 17 for the proper orientation of these parts.
1. Attach the Power Head Assembly (A) to the top of the Base Section (8) by sliding it into the Base
section. Align the two sections with the cut outs on the same side, and secure them together with two
BHCS (9). Attach the Adjustment Knob (1) to the threaded end of the Rod Assembly (4) which is
protruding from the top of the Power Head. After a few turns of the Adjustment Knob (1), press the Rod
Assembly down as far as it will go. This will aid in the assembly with the Wet Head Assembly.

Head into the Base Section. Square up the two sections with the diaphragm assembly facing the front, and
secure them together with two BHCS (9).
