The     mark indicates an action that must be taken, or instructs how to perform a task. The symbol 

   inside the mark describes the precaution in more detail ("provide ground work", in the case of the 

   example on the left).

The     mark indicates a WARNING or CAUTION item. The symbol inside the mark describes the 

   precaution in more detail ("electrical shock", in the case of the example on the left).

● 

: Operating the equipment improperly by failing to observe this precaution may possibly

The     mark indicates a prohibited action. The symbol inside the mark, or a notation in the vicinity of

   the mark describes the precaution in more detail ("disassembly prohibited", in the case of the 

   example on the left).

Be sure to thoroughly read and understand the SAFETY PRECAUTIONS given in this section before using 

the equipment in order to operate the equipment correctly.

The precautionary measures described in this section are intended to prevent danger or damage to you or 

to others. The contents of this manual that could possibly be performed improperly are classified into two 

categories: 

     

WARNING

, and       

CAUTION

. The categories indicate the extent of possible damage 

or the urgency of the precaution. Note however, that what is included under      

CAUTION 

may at times 

lead to a more serious problem. In either case, the categories pertain to safety-related items, and as such, 

must be observed carefully.

1 BE SURE TO READ FOR YOUR SAFETY

Do not operate the product under any conditions other than those for which it is speci-

fied.

 Failure to observe the precaution can lead to electrical leakage, electrical 

shock, fire,  or water leakage, etc.

Capacity

When transporting the product, pay 

close attention to its center of 

gravity and mass. Use an appropri-

ate lifting equipment to lift the unit. 

Improper lifting may result in the 

product damage, injury, or death.

Electrical wiring should be 

performed in accordance with all 

applicable regulations in your 

country. Provide a dedicated earth 

leakage circuit breaker and a 

thermal overload relay for the pump. 

Imperfect wiring or neglecting the 

installation of proper equipment 

will cause electrical leakage, fire, 

or explosion at worst.

Use a power outlet that has a sufficient rating and has been exclusively 

provided for the pump. 

If the power outlet is shared with other equipment, 

it can lead to an abnormal heat of the outlet and can cause fire as a 

result.

Install the product properly in 

accordance with this instruction 

manual. 

Improper installation 

may result in electrical leakage, 

electrical shock, fire, water 

leakage, or injury.

Provide a secure grounding 

dedicated for the product. Never 

fail to provide an earth leakage 

circuit breaker and a thermal 

overload relay in your starter or 

control panel (Both available on 

the market). 

If an electrical 

leakage occurs by due to a 

product failure, it may cause 

electrical shock.
