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
Do not pull, knot, or crush the power cable. Damage to the power

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.

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
as benzine or thinner. This may discolour the pump or
erase printing. Use a dry or damp cloth or a neutral
detergent.
