  Warning

 

 

 

Securely install the ground wire and make sure to 
carry out grounding work.

   

Otherwise, electrical leakage or electric shock may result. 

 

Do not connect the ground wire to a gas pipe or water 
pipe.   

Such connection is illegal and leads to electric shock, explosion 
and/or fire. 

 

Make sure that all electric wires are securely 
connected.   

Otherwise, it may cause fire and/or electric shock. 

 

 

Before carrying out maintenance/inspection work, be 
sure to stop the pump, and turn off the main power 
supply. 

Otherwise, electric shock, injury, breakage, water leakage, etc. 
may result. 

 

Before starting the equipment or carrying out 
maintenance/inspection work, ensure that all the 
relevant operators are informed of the operation 
and that there are no workers in the dangerous 
zone around the equipment. 

Otherwise, it may cause an unforeseen accident. 

 

 

In the case of a power failure, turn off the main power 
supply. 

Otherwise, when the power is restored, the pump suddenly 
starts, which may cause injury. 

 

When checking smooth rotation of the pump 
shaft, be sure to disconnect the main power 
supply before rotating it by hand.   

Otherwise, it may result in injury and/or breakage. 

 

Do not perform idling or operation with insufficient 
priming. 

Otherwise, the internal parts may be damaged by a heat shock.   

 

 

Do not put your finger or any foreign objects into 
openings or rotating part of the motor during 
operation.   

Otherwise, injury and/or breakage may result. 

 

Do not continue shut-off operation more than 1 
minute. 

Otherwise, the temperature and pressure in the pump rise, and 
it may get broken. 

 

 

Do not remove the coupling guard except during 
maintenance. Do not perform operation when the 
coupling guard is removed. 

Otherwise, injury and/or breakage may result. 

 

 

For work such as replacement of parts, repairs, or 
inspection that requires disassembly of the 
equipment, be sure to contact a specialized vendor or 
the service center designated by TERAL. 

If unskilled personnel carry out work that requires special 
knowledge, it may lead to an accident and/or failure. 

 

Do not operate the equipment if it does not run 
normally or abnormal condition is observed in 
parts, components, and others. 

Otherwise, it may lead to injury, failure and/or various 
accidents.

 

 

Do not operate the equipment in an explosive 
atmosphere. 

Otherwise, it may lead to injury, failure and/or various accidents. 

 

  Caution 

 

Use the equipment within its specified product 
specifications.   

Otherwise, it may cause electric shock, fire, water leakage, 
failure, etc.

 

 

Do not use the product alone in a place

 

directly 

related to important equipment or maintenance of life.   

Water supply may be stopped in the case of a failure. Be sure to 
keep a standby machine. 

 

Do not modify the product. 

The warranty does not cover an accident or a failure caused 
by a modification of the product. 

 

Do not give a shock to the pump when transporting or 
carrying in it. 

Otherwise, breakage may result. 

 

Check the upside and the downside, and carefully 
unpack the product

 

with particular attention to the 

nails. 

Otherwise, injury and/or breakage may result. 

 

Install the equipment in the environment in strict 
compliance with the installation instructions. 

Otherwise, a premature failure may result. 

 

Check that the floor surface at the installation 
location  is treated with waterproof  materials and 
equipped with a drainage system. 

Otherwise, serious damage may result when water leakage 
occurs. 

 

Before operation, thoroughly clean (flush) the inside 
of the piping. 

Otherwise, foreign objects may enter from the piping system, 
and an accident or failure of the pump may be caused by the 
supplied mixed liquid. 

 

Do not leave any tools and other objects on the 
top of the pump during operation. 

Otherwise, injury and/or breakage may result. 

 

Do not step on the pump or the piping. 

Otherwise, injury and/or breakage may result. 

 

Do not touch any part of the pump during 
operation unless absolutely necessary. 

 

 

Do not touch the pump if handled liquid is hot. 

You may burn your hands because it is hot.
