(11) Please connect a pump to a power supply. Please attach an appropriate terminal to an
installation terminal stand surely by all means. It causes the electric shock. Please
perform wiring, setting construction according to use local laws and ordinances, safety
requirements. A green insulation coated electric wire is a ground with or without a yellow
stripe.
(12) When take off the power supply cord of the pump, turn off a device main power supply
by all means, and please exclude a code from a terminal stand. It causes the electric
shock.
(13) Touching the power cord with wet hands may result in electric shock.
(14) Touching electrical wiring etc while inserting the power cord may result in electric shock.
(15) Do not remove the cover of capacitor, it causes the electric shock.
Operation
(16) This pump is not designed to be explosion-proof, and should therefore not be used in the
vicinity of inflammable substances (e.g. inflammable solvents) or in explosive
atmospheres. Failure to follow these requirements may result in injury or fire.
(17) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
(18) 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
(19) The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
(20) To prevent ingestion of microscopic particles resulting from wear of components,
use a dust mask and gloves when replacing cup packing, inlet and outlet valves, and
gaskets.

Caution
Installation
(1) 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.
(2) The fine clearances used in this pump require that the following conditions be satisfied
during storage, installation, and operation.
1. Ambient temperature during operation : Ambient temperature range of product
specification .(refer to table1-1)
