(1)After water is filled, close the drain valve. If there is a suction valve, open all the
suction valve.
(2)Jog (turn on the switch and then turn it off immediately) once or twice to confirm that
there is no problem with the operation. Also confirm the direction of rotation. (Crockwise
rotation when viewed from the motor fan side)

(3)After the rotation speed has reached the rated speed, slowly open the drain valve and
enter continuous operation.
(4)Confirm that there is no problem with pressure, current, vibration, sound, etc. (For
others, refer to "6.Maintenance"). Except during measurement, the valves of pressure
gauges and vacuum gauges should be kept closed. If its valve is left open for an extended
period of time, it can cause damage.
(5)If there is no check valve installed on the discharge side, when stopping the operation,
slowly close the discharge valve and then stop the motor.
(6)For the operation after the second time, please refer to the content of "6.Maintenance".
If there is no abnormality, it can be operated immediately.

Check the direction of rotation of the pump. When the three-phase
power supply is running in reverse, the wiring should be exchanged
to make it run in the forward direction.
It cannot be run in reverse. Vibration can loosen impeller nuts and
bolts and cause accidents.
To avoid operating in cavitation conditions. If the flow rate is
too
large
during
operation,
vibration and noise occur and the specified flow rate (pressure)
cannot be reached, cavitation will inevitably occur. At this time,
close the gate valve of the discharge port and reduce the flow
rate.
If the air mixed in the water pumping process is not discharged,
it will cause damage to the bearing and shaft seal, so that the
water cannot be pumped.
