・Cautions for Safety in Use
Applications
(1) This pump is not designed to be explosion-proof, and should therefore not be used to
discharge explosive gases. Such use may result in injury and fire.
(2) In addition to discharge of gas via the outlet, gas may also leak from other parts of
the pump, and it should therefore not be used with toxic gases. If toxic gas is
discharged for any reason it is important to note that the interior of the pump will be
contaminated by the gas, requiring appropriate caution during maintenance.
Maintenance and Repair
(3) When requesting the manufacturer’s service division to dismantle and repair the
pump, always note the gas which the pump has been used with on the Usage Check
Sheet. Note that if it has been used to discharge toxic gas for any reason it will be
contaminated. Please be aware that use with some gases will preclude dismantling
and repair.

Installation
(1) Do not use the pump in an explosive atmosphere. Such use may result in injury and
fire.
(2) Ensure that there are no inflammable materials such as solvents in the vicinity when
using the pump.
(3) Ensure that the pump is freely ventilated to prevent overheating, which may result
in fire or burns.
Power Supply
(4) Always check the pump and install wiring with the power cord disconnected. Working
with power connected may result in electric shock, or the pump starting
unexpectedly.
(5) Ensure that wiring is installed by persons qualified in accordance with regulations for
wiring (e.g. technical standards for electrical equipment, requirements for internal
wiring). Incorrect wiring with may result in fire.
(6) Ensure that lead wiring is properly connected and insulated with insulation tape (or
an insulating cap).
(7) Always ensure that the pump is correctly earthed. A dedicated earth leakage breaker
is recommended. Failure to earth the pump correctly may result in electric shock if a
fault or earth leakage occurs.
(8) Use the pump only at the rated voltage. Use at other than the rated voltage will
interfere with operation of the overload protection device, and this may result in the
motor burning out, or fire.
(9) Do not damage, modify, and pull the power cord, or place objects on it. Damage to the
cord may result in electric shock or fire.
(10)Always fully insert the power cord into the socket. Partial insertion may result in
electric shock.
(11)Remove the cord from the socket while holding the plug. 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.
(14)The electric motor fitted to this pump incorporates a thermal protector, however it is
not guaranteed to be open when it eventually fails at some time after the guaranteed
6000 cycles. For safety reasons therefore, it is necessary to fit an overload (over
current), protection device and an earth leakage breaker.

Operation
(15) 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.
(16) Inserting fingers or objects into the motor inlet may result in electric shock, injury,
or fire.
(17) Do not operate the pump with the outlet blocked, or with equipment which may
impede the flow of air placed in front of the outlet. Operation under such conditions
will result in an increase in the internal pressure of the pump, and may result in
rupture of the pump itself.
This pump is not pressure resistant, and may be used at a maximum internal
pressure of 30.0 kPa (gauge pressure).
Operation at a discharge resistance equivalent to 30.0 kPa (gauge pressure) may
result in the motor being overloaded.
Ensure that cooling and load conditions for the particular application are considered
thoroughly, and that the temperature increase for each motor component is within
the requirements for class of motor insulation as legally required in your country.
Installation
(1) The fine clearances used in this pump require that the following conditions be
satisfied during storage, installation, and operation.
1. Ambient temperature of 0 - 40°C and maximum relative humidity of 85% during
operation.
2. Other conditions for storage and operation.
