6WARNING

Turn off power before service

Risk of electrical shock. Be sure to turn off power to stop the pump

and related devices before service is performed.

Stop operation

If you notice any abnormal or dangerous conditions, suspend op-

eration immediately and inspect/solve problems.

Do not use the pump in any condition other than its intended purpose

The use of the pump in any conditions other than those clearly

specied may result in failure or injury. Use this product in specied

conditions only.

Do not modify the pump

Alterations to the pump carries a high degree of risk. It is not the

manufacturer's responsibility for any failure or injury resulting from

alterations to the pump.

Wear protective clothing

Always wear protective clothing such as an eye protection, chemical

resistant gloves, a mask and a face shield during disassembly, assem-

bly or maintenance work. The specic solution will dictate the degree

of protection. Refer to MSDS precautions from the solution supplier.

Use of hazardous chemicals

Risk of personal injury or re. Check/monitor plumbing system for a

leak before or in operation when handling a ammable, corrosive or

harmful liquid.

Do not damage the power cable

Safety instructions

CAUTION

Qualied personnel only

The pump should be handled or operated by qualied personnel with a

full understanding of the pump. Any person not familiar with the prod-

uct should not take part in the operation or maintenance of the pump.

Use specied power only

Do not apply power other than that specied on the nameplate.

Otherwise, failure or re may result. Ensure the pump is properly

grounded.

Do not run pump dry

Running the pump without liquid, friction heat builds up and dam-

ages the internal parts of pump.

Ventilation

Fumes or vapors can be hazardous with certain solutions. Ensure

proper ventilation at the operation site.

Do not install/store the pump:

• Where ambient temperature can exceed 0-50ºC (32-125ºF).

• In a flammable atmosphere or in a dusty/humid environment.

• In direct sunlight or wind & rain.

• In mechanical vibration.

• In a corrosive atmosphere such as chlorine gas.

Spill precautions

Ensure protection and containment of solution in the event of

plumbing or pump damage (secondary containment).

Do not stand on the pump

Personal injury may result as the pump turns over.

Do not touch the pump or pipe with bare hands

Risk of burning. The surface temperature of the pump or pipe rises

high along with liquid temperature in or right after operation.

CAUTION

Requirement

Caution

Prohibited

8CAUTION

Keep electric parts and wiring dry

Risk of re or electric shock. Install the pump where it can be kept dry.

Keep away from around the pump when turning ON power

The pump doesn't have an ON-OFF switch and starts as the power

cable is plugged in with 1-5VDC control voltage provided.

Remove foreign matters

Turn off power and clean the pump if foreign matters enter the

pump. Otherwise, the pump may be damaged.

Static electricity

When low electric conductivity liquids such as ultra-pure water and

fluor inactive liquid (e.g. FluorinertTM) are handled, static electricity

may generate in the pump and may cause static discharge. Take

countermeasures to remove static electricity.

Check pump head bolts

Liquid may leak if any of pump head bolts become loose. Tighten the

bolts diagonally and evenly by 1.6N•m before initial operation and at

regular intervals.

Do not use the pump in a wet location

The pump is not waterproof. Use of the pump in wet or extremely

humid locations could lead to electric shock or short circuit.

Do no use a damaged pump

Using a damaged pump could lead to an electric shock or death.

Disposal of the used pump

Dispose of any used or damaged pump in accordance with local

rules and regulations. If necessary, consult a licensed industrial

waste disposal company.

Do not pressurize the pump

If the pump is pressurized over the maximum discharge pressure, O

ring seal may be impaired and leakage may result.

Safety instructions

Precautions for use

• Electrical work should be performed by a qualified electri-

cian. Otherwise, personal injury or property damage could

result.

• Do not install the pump:

–In a ammable/corrosive/explosive atmosphere.

–In a dusty place.

–In direct sunlight or wind & rain.

–In mechanical vibration.

– Where ambient temperature can exceed 0-50ºC (32-

125ºF).

–Where ambient humidity can exceed 30-85RH.

• Allow sufcient space around the pump for easy access

and maintenance.

• Use care handling the pump. Do not drop. An impact may

affect pump performance. Do not use a pump that has

been damaged to avoid the risk of electrical damage or

shock.

the pump before operation.

Precautions for use

Caution

Requirement

10 Precautions for use

• The pump is not waterproof. Do not operate the pump while

wet with solution or water. Failure or injury may result. Im-

mediately dry off the pump if it gets wet.

• Do not close discharge line during operation. Solution may

leak or piping may break.

• Solution in the discharge line may be under pressure.

Release the pressure from the discharge line before dis-

connecting plumbing or disassembly of the pump to avoid

solution spray.

• Wear protective clothing when handling or working with

pumps. Consult solution MSDS for appropriate precautions.

Do not come into contact with residual solution.

• Do not clean the pump or nameplate with a solvent such
