 Caution

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.

Do not expose the motor to water. 

Otherwise, it may lead to an electric shock, electric leak, 
failure, or other problems. 

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

Otherwise, it may lead to overheating or ignition.

Do not place any obstacles around the product that 
may hinder ventilation. 

Otherwise, it may lead to a fire.

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. 

Never run the pump dry (no-discharge operation) or 
with insufficient amount of priming liquid. 

Otherwise, it may cause damage to the sliding part of the 
pump.

Do not run the pump with tools or other objects 
placed on the unit. 

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

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. 

Be sure to install the strainer at the suction side of 
the pump. 

Otherwise, foreign objects may enter into the piping and thus 
cause damage to the sliding parts of the pump. 

Be sure to carry out inspection according to the 
Maintenance checklist. 

Otherwise, you cannot prevent potential failures, thus leading 
to a higher risk of accidents.

Do not touch the motor if the liquid used exceeds 

40°C

.

The surface of the pump may be so hot that it may cause 
burns. 

Once you turn off the power, wait until the pump 
stops completely. Do not restart the pump until it 
does. 

Otherwise, the main shaft may be subjected to an excessive 
load, which makes the service life of the pump shorter. 

Do not place any combustibles around the product.

Failure to observe this may cause fire. 

Minimize the frequency of startups and shutdowns 
of the pump (Max. five times per hour). 

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

Ensure to install an overcurrent protective device. 

The user is required by the technical standards for electrical 
facilities to install one. Otherwise, it may damage the product, 
thus leading to a fire or failure. It is also recommended to 
install protective devices such as a ground fault interrupter. 

When you lift the product by hand, pay attention to 
its weight. Do not allow a single person to lift a 
product heavier than 15 kg. 

Otherwise, it may put strain on the body, thus leading to an 
injury. 

Before lifting the product, refer to the catalog, 
dimensional drawing, and other documents to 
check the weight of the product. Do not lift the 
product if its weight exceeds the rated load of the 
hoisting devices.   

Otherwise, the product may topple over or fall, thus leading to 
an injury. 

Whenever disassembly and inspection of the 
pump, replace the packing and O-ring. 

Otherwise, it may lead to liquid leakage. 

Before disassembly, be sure to close the 
suction/discharge valve and drain the 
high-pressure water in the pump/piping. 

Otherwise, the product may topple over or fall, thus leading to 
an accident. 

When the pump is not used for a long time, turn off 
the main power and the pump shall be sufficiently 
drained for storage. 

Otherwise, it may lead to liquid leakage. 

Take the companion flange out of the pump and 
screw the pipes. 

Otherwise, It may lead to damage or leakage.
