・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.

Danger

－3－

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.
