3. Tube connection
Push the tubes into the inlet and outlet as far as they will go.
Use tube bands to make sure tubes are fastened as neces-
sary.
NOTE: If suction line connection is imperfect, the pump sucks
air and it prevents the pump from bringing out full per-
formance.
4. Connection checkout
Check that a suction line is connected to the inlet and a dis-
charge line is connected to the outlet.
CAUTION
If a suction line and a discharge line are connected the
other way around, pumping process is inverted.
5. Valve mounting
For adjustment of an air flow and a vacuum (not for liquid flow
adjustment), install a control valve on a suction line.
2.3 Electrical wiring
Electrical wiring must be performed by a qualified electrician.
We are not responsible for personal injury or property dam-

Before wiring
1. Confirm that power is disconnected before work.
2.
Wiring work should be done in accordance with local elec-
tric codes. Use the recommended wiring accessories.
3. Observe the rated voltage specified on the name plate.
4. After wiring work, check that the system is free from the
inductive noise at start-up. The maximum length of power
and signal leads is 3m. Take appropriate measures when
extending the leads over the maximum length.
5. The drive circuit generates noise because of its high-speed
switching. Check if peripheral devices are not affected by
the noise.
6. When an earth leakage breaker is used and has tripped,
always investigate and solve root causes. Be sure to unplug
the pump before investigation is performed.
7. This pump can be controlled by 1-5VDC control signal and
make feedback control when used with a flow sensor.
8. Always use the 1-5VDC control signal for ON-OFF control.
9. Always stop the 1-5VDC control signal before turning ON or
OFF the pump power.
