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 a speci-
ed conditions only.

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 product should not take part in the operation or maintenance of
the pump.
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.
• In a dusty/humid environment.
• Where operating (or storage) temperature can fall below 5ºC (or
0ºC) or exceed 40ºC.
Spill precautions
Ensure protection and containment of solution in the event of
plumbing or pump damage (secondary containment).
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.

8CAUTION
Do no use a damaged power cable
Risk of fire or electric shock. The cable is not replaceable. The
whole pump unit needs to be replaced when the cable is damaged.
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.

Safety instructions
• Electrical work should be performed by a qualied
electrician. Otherwise, personal injury or property
damage may result.
• Do not install the pump in a place where the pump
can get wet. Avoid using wet gas, or internal con-
densation will build up and consequently result in
the short lives of the valve and diaphragm.
• Do not use the pump in a dusty place. Be sure
to provide the inlet with a filter to prevent foreign
matters from getting into the pump. Otherwise, the
pump performance may reduce or the lives of the
valve and diaphragm remarkably shorten.
• Do not install the pump in a corrosive or flamma-
ble gas atmosphere. Keep good ventilation in a
working area. Ambient temperature should not fall
below 5°C or exceed 40°C. Observe the allowable
gas temperature range of 0 and 40°C.
• If the compressed air (higher pressure than atmos-
pheric pressure) is transferred to the pump, sharp
deterioration to the lives of the valve, diaphragm
and bearing may result. Always keep atmospheric
or lower pressure in the suction line.
Precautions for use
Precautions for use
Caution
Do not increase suc-
tion line pressure

10 Precautions for use
• Do not tube two or more pumps in series. It may
prevent the motor from starting and lead to a burn
out.
• Injection point must be below the pump position.
Or siphon action or back flow may result.
• 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.
• Do not apply power other than that specified on
the nameplate. Otherwise, failure or fire may
result.
• The pump can not start with full discharge/suc-
tion pressure. Remove pressure before operation.
After a long period of stoppage, pump perform-
ance at the beginning of operation becomes occa-
sionally unstable. In this case, warm the pump up
for 10 minutes with no discharge line pressure.
