Power Supply 

(5) 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. 

(6) 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. 

(7) Ensure that lead wiring is properly connected and insulated with insulation tape (or an insulating 

cap). 

(8) This pump has thermal protector. But it is detect of temperature only. Suitable overcurrent 

protection device shall be installed at the final installation.

 

(9) 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. 

(10) 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. 

(11) 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. 

(12) Always fully insert the power cord into the socket. Partial insertion may result in electric shock. 

(13)  Remove the cord from the socket while holding the plug. Failure to do so may result in electric 

shock. 

(14)   Touching the power cord with wet hands may result in electric shock. 

(15)   Touching electrical wiring etc while inserting the power plug may result in electric shock. 

(16) 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 

(17) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire. 
(18) 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. 

(19) 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. 

(20) Do not use it for the human body.   

And do not use in applications involving organ transplants, or contact with body fluids or living 

tissue. 

(21) 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.
