WARNING
- If using the pump with a flammable material or in a flammable environment, read the
applicable operating caution on P.3.
CAUTION
- 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.
- When operating the pump, operation noise may be generated, depending upon conditions of
use (kind of material 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 [9.1 Main specifications].)
- When pumping a hazardous material (hot, flammable, strong acid, etc.), provide protective
measures (installation of a pit or sensors, etc.) in consideration of possible leakage of
material, and post warning signs at necessary places. For details, see the applicable
operating caution on P.2 and P.4.

NOTE

Arranging outside exhaust
- Remove the silencer.
- Connect a hose with a ground wire to the pump's 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.
WARNING
- Be sure to have a pit, a protection box, etc. at the end of the hose in preparation for the flow
of material in case of damage to a diaphragm. For details, see the applicable operating
caution on P.2.
- Pump exhaust should be directed to a safe place, away from people, animals and food.
＜
NOTE
＞
When air line operation is to be controlled by a solenoid valve, a three way type is recommended.
A three-way solenoid valve allows any trapped air to bleed off, in turn improving pump performance.
