  Warning

 

 

 

Be  sure  to  keep  the  terminal  box  cover  attached 

during the operation of the pump. 

Otherwise, it may lead to an electric shock. 

Do not forcibly bend, pull, or pinch the power cable 

or any lead wires of the product.   

Otherwise, it may lead to an electric shock or fire. 

 

 

Check the wiring sections and wires for any 

looseness. 

A loose connection may cause a fire or electric shock. 

Before starting the maintenance or inspection work, 

be sure to stop the pump and turn off the main 

power of the panel board. 

Otherwise, it may lead to an electric shock, injury, damage, or 

leakage. 

 

Before starting the unit or carrying out 

maintenance/inspection work, ensure that all the 

relevant workers are informed of the operation and 

that there are no workers in the dangerous zone. 

Otherwise, it may lead to an unforeseen accident. 

Before rotating the pump shaft by hand to check its 

smooth rotation, be sure to turn off the main power.

Otherwise, it may lead to an injury or damage. 

 

 

After turning on the power, do not touch any parts of 

the pump other than those required for operation. 

Otherwise, it may lead to an electric shock or injury. 

Do not perform long hours of zero-discharge 

operation continuously. 

Otherwise, the temperature and pressure may increase inside 

the pump, thus damaging the pump or causing steam to blow 

off. 

 

 

Do not put your fingers or foreign objects into any 

openings or rotating part of the motor during 

operation. 

Otherwise, it may lead to an injury or damage. 

For overhaul, replacement of parts, or repairs, ask 

the vendor or the service center specified by 

TERAL. 

If  unskilled  personnel  carry  out  work  that  requires  special 

knowledge, it may lead to an accident or failure. 

 

In the event of a power failure, be sure to turn off the 

power switch. 

Otherwise,  the  pump  may  suddenly  start  up  on  restoration  of 

the power, thus leading to an injury. 

 

 

 

 

 

 

  Caution 

 

 

Do not use the unit outside the range of the product 

specifications. 

Otherwise, it may lead to an electric shock, fire, leakage, failure, 

or other problems. 

Do not use the unit at an incorrect power voltage. 

An incorrect voltage may damage the motor. 

 

Do not use a single pump unit as the only means of 

directly operating key facilities or sustaining life. 

In the event of a failure, the liquid supply may stop. Ensure to 

make a backup unit available for operation. 

Before unpacking the delivered container, check 

that the container is placed in the correct 

orientation (not upside down). Carefully unpack the 

container, while paying special attention to fitting 

metals. 

Otherwise, it may lead to an injury or damage. 

 

Ensure that the floor at the unit’s installation place is 

waterproofed and fitted with drainage. 

Otherwise, it may lead to serious damage in the event of 

leakage. 

Do not install two or more different cables or control 

wires in one pipe or duct. 

Otherwise, it may lead to malfunction of the product or other 

equipment. 

 

Do not step on the pump, motor, cable or pipe. 

Otherwise, it may lead to an injury, damage, or other problems.

Do not expose the motor to liquid. 

Otherwise, it may lead to an electric shock, electric leak, 

failure, or other problems. 

 

Operate the controls carefully. 

Otherwise, it may lead to an injury or damage. 

During test operation, never run the pump dry (i.e. 

never run the pump when the liquid level is below 

the Minimum liquid level). 

Otherwise, it may lead to damage or a fire.

 

 

Before operation, thoroughly clean (flush) the inside 

of the piping to remove foreign matter. 

Otherwise, the piping system may be contaminated with foreign 

matter, thus leading to an accident or a pump failure. 

During normal operation, do not run the pump dry.

Otherwise, it may lead to damage or a fire. 

 

Do not put a cloth or other covering on the motor. 

Otherwise, it may lead to overheating or ignition. 

Do not touch the motor body while the pump is 

running or immediately after the pump has stopped.

Otherwise, you may get burns from the hot surface. 

 

In the event of an alarm or abnormal condition that 

cannot be resolved, immediately stop the operation, 

turn off the power, and then contact TERAL or its 

service provider. 

Otherwise, it may lead to an accident. 

Do not run the pump with tools or other objects 

placed on the unit. 

Otherwise, it may lead to an injury or damage.
