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.

Ventilation

Fumes or vapours can be hazardous with certain solutions. Ensure

proper ventilation at the operation site.

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.

Install a relief valve

Install a relief valve on a discharge line near the pump so as to

release the discharge pressure when it exceeds the maximum level. Requirement

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.
