Starting process
Operate the pump according to the following procedure after installation, tubing and wiring of pump.
No. Points to be checked Procedure
1
Tubing, wiring and voltage ● See " ■ Plumbing " and " ■ Wiring " sections.
● Check the spec label to see if the power supply voltage is
correct.
2 A discharge and a suction line. ● Fully open both suction and discharge valves.
3
Rotational direction ● Check if the direction of rotation is correct.
Prime the pump and run the motor for just a moment to
check a flow direction.
● Counter clockwise (CCW)
CCW rotation seen from the
motor end. Liquid flows in the
direction of "a".
● Clockwise (CW)
CW rotation seen from the
motor end. Liquid flows in the
direction of "b".
4
Starting ● Run the pump for a while and check liquid flows without a
hitch. Upon finding abnormality, turn off power and solve the
cause of abnormality. Refer to "Troubleshooting" section.
5
Operation ● Make sure air has been expelled from the pump and a tub-
ing system completely. If not, an accurate flow rate can not
be obtained. Angle the pump head to 20º and run the pump
until air is expelled completely. After air is all eliminated,
adjust discharge pressure to a specified level.
● Flow rate can be adjusted from 0 to the maximum by chang-
ing the pump head angle.
6
Points to be checked during
operation ● Do not allow foreign matters to enter the pump. Foreign mat-
ters may cause the plunger to be locked or damaged, hin-
dering a liquid circulation.
Install a dampener to reduce pulsation as necessary. Contact for us for detail.
