Safety Instruction

Warning

Turn off the power supply.

 

Working without disconnecting the power supply may

 

cause an electrical shock.  Before engaging upon any

 

working procedures involving the pump, make sure to turn

 

the power supply switch off and to stop the pump and

 

other related devices.

Terminate operation!

 

When you detect or become aware of a dangerous sign or

 

abnormal condition during operation, terminate the

 

operation immediately and start it from the beginning

 

again.

For specified application only.

 

The use of a pump in an application other than those

 

clearly specified may result in injury or damage to the

 

pump.  Use the pump strictly in accordance with the pump

 

specifications and application range.

No remodeling!

 

Never remodel a pump. Otherwise, a serious accident

 

may result. Iwaki will not be responsible for any accident

 

or damage of any kind which is caused by the user

 

remodeling the pump without first obtaining permission or

 

instructions from Iwaki.

Wear protectors.

 

If you touch or come in contact with any type of

 

hazardous chemical liquid, including but not limited to

 

chemicals, you may experience a serious injury.  Wear

 

protective gear (protective mask, gloves, etc.) during the

 

pump operation.

Caution

Damaged pump

 

Never operate a damaged pump. A damaged pump may

 

cause leakage or electrical shock.

Operating site must be free of water and

  humidity

 

The pump is not designed to be water-proof or dust-proof.

 

The use of the pump in places where water splashes or

 

humidity is high may result in an electrical shock or short

 

circuit.

Do not damage or change power cable!

 

Do not scratch, damage, process, or pull the power cable

 

forcibly. An extra load onto the cable, such as heating the

 

cable or placing something heavy on the cable, may

 

damage the cable and finally cause a fire or an electrical 

 

shock.

Do not cover the motor!

 

Running a covered motor may accumulate heat inside the

 

motor and cause a fire or a mechanical failure. Ventilate

 

the motor sufficiently.

Arrange grounding!

 

Do not operate the pump without connecting the

 

grounding wire. Otherwise, an electrical shock may

 

result. Make sure the grounding wire is connected with

 

the grounding terminal.

Caution

Qualified operators only!

 

The pump operator and pump operation supervisor must

 

not allow any operators who have little or no knowledge

 

of the pump to run or operate the pump. Pump operators

 

must have a sound knowledge of the pump and its

 

operation.

Specified power only.

 

Do not operate the pump on voltage which is not specified

 

on the nameplate. Failure to do so may result in damage

 

or fire. Only the specified power level is to be applied.

Do not wet or dampen!

 

If the motor or wiring cable becomes wet or dampened

 

with the operating liquid by mistake, this may result in a

 

fire or cause an electrical shock. Install the motor and

 

wiring cable in positions which are not likely to become

 

wet or dampened with any liquid.

Ventilate!

 

Poisoning may result during an operation which involves

 

toxic or odorous liquid. Ventilate the operating site

 

sufficiently.

Spill-out accident!

 

Protective measures should be taken against any

 

accidental spill-out or leakage of the operating liquid as a

 

result of unexpected damage on the pump or the related

 

piping.

Caution

Install an earth leakage breaker (option)!

 

The operation of a pump without using an earth leakage

 

breaker may cause an electrical shock. Please purchase an

 

optional leakage breaker and install in the system.

Power cable cannot be replaced.

 

Never use a damaged or affected power cable. Otherwise,

 

a fire or an electrical shock may result. Handle the power

 

cable carefully, as it cannot to be replaced with a new

 

cable. (The pump unit itself must be replaced in that

 

circumstance.)

Limited operating site and storage

 

Do not install or store the pump in the following places:

 

* Places where a flammable gas or material is used or

 

stored.

 

* Places where the ambient temperature is extremely high

 

(40

˚

C or higher) or extremely low (0

˚

C or lower).

Do not drain the liquid in the site.

 

The liquid discharged out of the pump, including a

 

hazardous chemical liquid, must be drained into a special

 

container. Never drain such liquid directly onto the floor

 

in or near the operation site.

Disposal of used pump

 

Disposal of used or damaged pumps must be done in

 

accordance with the relevant local laws and regulations.

 

(Consult a licensed industrial waste products disposing

 

company.)
