WARNING
• When pumping a hazardous fluid (hot, flammable, strong acid, etc.) with this product,
provide protective measures (install a pit, a protection box, sensors, etc.) in consideration of
possible leakage of fluid, and post warning
signs at necessary places.
Make the warning symbols in
“12.Warning symbols”, and
attach them to the casing and
piping, etc.
Leakage of fluid may cause fire,
air pollution or a serious accident.
When pumping a hot fluid, the
casing and piping will become hot,
which may burn the skin when
touched.
• Before using this product, be sure you are familiar with the precautions regarding the fluid
to be pumped, and verify the corrosion resistance of the parts that will come into contact
with the fluid. NEVER use the product with any fluid against which it does not have
sufficient corrosion resistance or with a fluid that poses a risk of explosion. If you are unsure
of the corrosion resistance, contact your dealer or our regional office. If you use this product
with any fluid against which the parts that will come in contact with the fluid do not have
sufficient corrosion resistance, it may result in damaging the product or leakage of fluid.
• When working in the vicinity of pumping of fluid with this product, be sure to wear
protective gear (goggles, mask, etc.).
• When using this product, observe the relevant regulatory rules concerning fire prevention,
labor safety standards, etc.
• If you have any questions on the operation of this product (method of connection or
installation), contact your dealer or our regional office.
CAUTION
• When operating this product, it may generate loud operating noise, depending upon the
condition of use (fluid pumped, supply air pressure and discharge pressure). If regulatory
rules apply, provide appropriate acoustic measures where necessary. (For the noise value of
this product, see “10.1 Main specifications”.)
• To drive this product, use supply air with minimum moisture content.
• If a diaphragm of this product is damaged, supply air may mix with the fluid or the fluid
may flow into the main body (air-switching portion). If air supply is inadequate or
contaminated, do NOT operate the pump.
• While operating this product, do NOT cover the intake port by hand.
• If the pump remains unused for a long period of time, or you have misgivings about running
the pump, please consult with the dealer where you purchased it or our Sales office.
