Procedure
Points to be checked
5 Adjust a discharge
capacity & a dis-
charge head to the
specified level.
Open a discharge-side valve gradu-
ally till a flow and a head reach
the specified level. Do not open or
close the valve sharply.
Note: Do not keep the discharge-
side valve closed more than 1
minute.
Note: Check that the pump trans-
fers a liquid without trouble.
If there is a problem, turn
off the power immediately
and solve the cause. See
"Troubleshooting" section of
page 17.
6 Points to be
checked during
operation
• Do not allow foreign matters to
enter the pump. Foreign matters
may cause impeller to be locked,
hindering liquid circulation. In this
case turn off power immediately
(Contact us).
• Turn off power when the leakage
breaker operates. Investigate the
root cause on "Troubleshooting"
section of page 17.
■ Degassing
Open a discharge line. The end of the line immersed in liquid is not
ideal for degassing. Take it out from liquid as necessary. Then run the
pump for one second. Repeat the one-second operation from three to
five times to expel air completely.
If an air vent line is laid on, open it instead of a discharge line before
degassing.
