Warning
Operation
(14) This pump is not designed to be explosion-proof. When using the pump, ensure that
there are no inflammable materials such as solvents, or explosive gases, in the vicinity.
Use under such conditions may result in injury or fire.
(15) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or
fire.
(16) Operating the pump with the discharge outlet blocked, or with a device which prevents
passage of gas to the discharge outlet, may result in rupture of the pump. The internal
pressure of the pump rises and the pump body may rupture and the motor become
overloaded.
This pump is not designed to be pressure-resistant. The internal pressure of the pump is
limited to 0.03 MPa (gauge pressure).
Maintenance and Repair
(17) The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
(18) To prevent ingestion of microscopic particles resulting from wear of components, use a
dust mask and gloves when replacing diaphragms, valves, and O rings.

Caution
Installation
(1) To prevent back injuries, always use at least two people when lifting and moving the
pump.
(2) Microscopic particles resulting from wear of components are discharged from the outlet
and contaminate the room. If necessary, connect a pipe from the discharge outlet to the
outside of the building.
(3) The fine clearances used in this pump require that the following conditions be satisfied
during storage, installation, and operation.
1. Ambient temperature of 7~40°C and maximum relative humidity of 85% during
operation.
2. Other conditions for storage and operation.
a) Level floor of sufficient strength.
b) No condensation
c) Dust-free environment
d) Well ventilated
e) Environment free of corrosive or explosive gas.
f) Not subject to direct sunlight.
g) No danger of fire.
h) Maximum ambient temperature of 40°C during assembly of pump.
