Step 4: Put the new diaphragm on the connecting rod to
replace the old one removed in Step 3. The front and rear
sides of the diaphragm are different from each other.
Refer to the pictures below to ensure that the front side is
the side which is facing up. Also, when you place the
diaphragm on the main pump unit, adjust its position so
that the spacing between the main pump unit, the
connecting rod and the diaphragm are even.

Step 5: After adjusting the position of the diaphragms,
attach the push plates for the diaphragms. These push
plates need to be attached in the correct orientation.
Refer to the diagram on the left to ensure that they are
positioned so that the counter bores make horizontal lines
when the power cord is facing toward you.
*Please pay extra attention to this procedure as attaching
the push plates in an incorrect orientation will lead to
product damage.
