7. Do not close the discharge or suction lines while in operation.
Pump operation with valves closed increases the load onto the pump itself and will eventually
damage the pump or piping.
8. Do not adjust the stroke length while the pump is not operating.
Rotating the stroke adjustment dial while not in operation applies load onto the dial and will
eventually damage the pump.
9. Allowable pressure limit
Set the discharge pressure at or below the allowable pressure limit level indicated in the
“Specifications” section.
10. Temperature/humidity fluctuation
Temperature fluctuation may not affect the performance of the pump itself. However, the
liquid may change in terms of its viscosity, pressure, or corrosion resistance. Pay special
attention to changes in liquid characteristics as a result of temperature fluctuation.
Liquid temperature range:
Material symbol VC, VH, VS:
0~50°C
Material symbol S6, TC:
0~80°C
Ambient temperature range:
0~40°C
Humidity range:
35~85%RH

Installation
1.
Installation position
Install the pump as close to the suction tank and as low as possible. Flooded
suction is the ideal installation.
The suction lift ability depends upon the liquid properties, temperature, and length
of the suction piping. For details of the setup, consult your distributor.
2.
Indoor and outdoor use
The pump can be operated either indoors or outdoors. However, safety measures should be
taken so as not to expose the motor and power distribution unit to flooding and it is always
recommended that the pump be shielded from direct exposure to the elements (rain, snow,
direct sun, etc.).
3.
Installation site
Select an installation site that is flat and free of vibrations caused by nearby machines.
Sufficient space for maintenance should be provided.
Lifting
Lift the pump horizontally so that the gear oil will not leak out of the pump drive unit.
