 Warning

Correctly and securely connect the wires according 
to the wiring diagram within the terminal box and the 
instruction manual. 

Incorrect wiring may cause a fire, electric shock, failure, or 
other problems. 

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

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

Make sure that all electric wires are securely 
connected. 

A loose connection may cause a fire or electric shock. 
*Shut off the main power before carrying out wiring works. 

Do not run the unit if abnormal condition is 
observed in any operation, movement, parts, etc. 

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

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 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 rotating the main 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. 

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. 

Be sure to put a shaft coupling guard during 
operation. 

Otherwise, it may lead to an injury. 

Be sure to keep the terminal box cover attached 
during the operation of the pump. 

Otherwise, it may lead to an electric shock. 

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 shutoff operation for more than one 
minute 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, 
contact Teral 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. 

Do not use the product in any explosive 
atmosphere. 

Otherwise, it may lead to any injury or fire. 

 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. 

Check that the delivered items are exactly what 
you ordered. 

The use of a wrong product may cause an injury or failure. 

Do not modify the pump. 

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

Do not run the pump at a frequency exceeding 60 
Hz (50 Hz for models dedicated to 50Hz). 

Otherwise, it may lead to motor burnout or a fire. 

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 water supply may stop. Ensure to 
make a backup unit available for operation. 

Do not give the product any physical shock during 
transportation, transfer, and installation. 

Otherwise, it may cause damage to the product.

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 use the unit at an incorrect power voltage.

An incorrect voltage may damage the motor. 

When two or more pumps are installed together, 
every pump should have its own separate suction 
piping. 

Otherwise, it may lead to an abnormal operation.

Strictly observe the precautions for installation on 
pump installation environment. 

Otherwise, It may lead to quick damage of the pump.

Do not step on the pump, motor, wiring and piping.

Otherwise, injury or breakage may result. 

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 nails. 

Otherwise, it may lead to an injury or damage. 

Operate the controls carefully. 

Otherwise, it may lead to an injury or damage. 

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.
