Assembly
Assembly is done in reverse order to
disassembly. Pay attention to the fol-
lowing points.
•
Pay attention to arrangement of the
valve set. Wrong arrangement and
direction will cause failed pumping
(liquid leakage, decreased discharge
capacity).
•
Be sure to mount the O ring and
gasket.

2)
Mount the suction side valve set
Put the valve set in the fitting (3)
