•Even if you do not use the cushions to secure the pump in place, mount it in such a way
that vibration generated by pump operation will be absorbed.
•If the pump will be submerged during operation, follow the steps below:
*Verify the corrosion resistance of each component of the pump, and do NOT expose the
pump to any fluid for which it does not have proper corrosion resistance.
*Exhaust should direct outside, not into the fluid in which the pump is submerged. For
information on how to arrange the exhaust, see Note: Arranging outside exhaust and
Fig. 3.2 below.
*Make sure that you can reach all of the valves without submerging your hand.
•When operating the pump, operation noise may be generated, depending upon conditions of use
(kind of fluid being pumped, supply air pressure and discharge pressure).
If any regulatory rules apply, provide appropriate acoustic measures. (For the noise level of this
product, see 10.1 Main specifications on p.26.)
•When pumping a hazardous fluid (hot, flammable, strong acid, etc.), provide protective measures
(installation of a pit or sensors, etc.) in consideration of possible leakage of fluid, and post warning
signs at necessary places. For details, see the applicable operating caution on p.4,5 and 6.

Arranging outside exhaust
•Remove the silencer.
•Connect a hose with a ground wire to the pumps exhaust port, and
attach the silencer to the tip of the hose. Use a hose of the same
diameter as the exhaust port. (If the hose is longer than 5 meters,
consult your dealer or our regional office.)
•Have a pit, a protection box, etc. at the end of the hose.

•Be sure to have a pit, a protection box, etc. at the end of the hose in preparation for the flow of
fluid in case of damage to a diaphragm. For details, see the applicable operating caution on
p.4,5 and 6.
•Pump exhaust should be directed to a safe place, away from people, animals and food.
