Safety instructions
WARNING
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, chemi-
cal resistant gloves, a mask and a face shield during disassembly,
assembly or maintenance work. The specic solution will dictate the
degree of protection. Refer to MSDS precautions from the solution
supplier.
Do not damage the power cable
Do not pull, knot, or crush the power cable. Damage to the power
cable could lead to a re or electrical shock if cut or broken.
Do not operate the pump in a ammable atmosphere
Do not place explosive or ammable material near the pump.

Requirement
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. Other-
wise, failure or re may result. Ensure the pump is properly grounded.
Do not run pump dry
Do not run pump dry for more than 30 minutes (even when the
pump runs for degassing). Otherwise, the pump head xing screws
may loosen and liquid may leak. Optimise your system. If the pump
runs dry for a long period (for more than 30 minutes), the pump
head and the valve cases may deform by friction heat and conse-
quently leakage results.
Keep electric parts and wiring dry
Risk of re or electric shock. Install the pump where it can be kept dry.
Observe an applicable MSDS
Take account of installation environment. Chemicals should be
controlled in accordance with a MSDS. Do not send potable water
or circulate heated water with this pump.
Do not install /store the pump:
• In a ammable atmosphere or a dusty/humid environment.
• Where ambient temperature can exceed 0-40ºC.
• In direct sunlight or wind & rain.
Spill precautions
Ensure protection and containment of solution in the event of
plumbing or pump damage (secondary containment).

Safety instructions
CAUTION
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.
Grounding
Risk of electrical shock! Always properly ground the pump. Con-
form to local electric codes.
Install a GFCI (earth leakage breaker)
An electrical failure of the pump may adversely affect other de-
vices on the same line. Purchase and install a GFCI (earth leakage
breaker) separately.
Preventative maintenance
Follow instructions in this manual for replacement of wear parts. Do
not disassemble the pump beyond the extent of the instructions.
Do not use a damaged pump
Use of a damaged pump could lead to an electric shock or death.
Disposal of a 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.
Check pump head bolts
Liquid may leak if any of the pump head bolts become loose.
Tighten the bolts diagonally and evenly by 2.16N•m before initial
operation and at regular intervals.
Solution compatibility
This pump has been evaluated for use with water only. The suitabil-
ity of this pump for use with liquids other than water, such as acid
and alkaline, is the responsibility of the user. For liquids other than
water, select the best-suited liquid end material combination using a
chemical compatibility chart.

10 Precautions for use
• Electrical work should be performed by a qualied electri-
cian. Otherwise, personal injury or property damage could
result.
• Do not install the pump:
–In a ammable atmosphere.
–In a dusty/humid place.
–In direct sunlight or wind & rain.
–Where ambient temperature can exceed 0-40ºC.
Protect the pump with a cover when installing it out of
doors.
• Select a level location, free from vibration, that won't hold
liquid. Anchor the pump with four M5 bolts so it doesn't
vibrate. If the pump is not installed level, output may be
affected.
• When two or more pumps are installed together, vibration
may be signicant, resulting in poor performance or failure.
Select a solid foundation (concrete) and fasten anchor bolts
securely to prevent vibration during operation.
• Allow sufficient space around the pump for easy access
and maintenance.
• Install the pump as close to the supply tank as possible.
• When handling liquids that generate gas bubbles (sodium
hypochlorite or hydrazine solution), install the pump in a
cool and dark place. Flooded suction installation is strongly
recommended.
