Casing A
(10) After the valves have been inserted into the casing A, cut off their respective pulling ends using
scissors or nippers. Secure casing B and valve chamber packing to casing A by the five screws.
This completes the valve replacement procedure, and use this assembly as a new casing block.

• When replacing the diaphragms, be sure to change the valves with new ones, too.
• When reinstalling the valves, take care to make sure that they are correctly fit in the exhaust and
intake sides. Wrong orientation may result not only in performance decreasing but in a failure of
the pump.
• Tighten each of five screws gradually and uniformly till they are firmly fastened.
If they are not tightened uniformly, it may cause leakage of air or failure of pump.
