Warning
Power Supply
(10) Ensure that the power cord used for the pump is appropriate for the rated voltage and
current. Use a 4-core cable, with each core wire having a cross-section area of 1.0mm
or more. Ensure that one of the core wires is used as an earth wire. Firmly attach the 6
- 12mm diameter SKINTOP compatible cable fitted with the appropriate terminals (M4
terminal block screws) to a terminal block. Failure to follow these requirements may
result in electric shock.
(11) Switch off the main power supply, and remove the power cord from the terminal block,
before disconnecting the power cord from the pump. Failure to do so may result in
electric shock.
(12) Touching the power cord with wet hands may result in electric shock.
(13) Touching electrical wiring etc while inserting the power plug may result in electric
shock.
Operation
(14) This pump is not designed to be explosion-proof, and should therefore not be used in
the vicinity of inflammable substances (eg inflammable solvents) or in explosive
atmospheres. Failure to follow these requirements 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 cup packing, inlet and outlet valves, and gaskets.

Caution
Installation
(1) To prevent back injuries, always use at least two people when lifting and moving the
pump. Use two persons to lift the upright vertical type of pump from its base.
(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.
