Caution
•
Spill-out accident
Protective measures should be taken against any accidental spill-out or leakage of
the operating liquid as a result of unexpected damage on the pump or the related
piping.
Caution
•
Qualified operators only
The pump operator and pump operation supervisor must not allow any operators
who have little or no knowledge of the pump to run and operate the pump. Pump
operators must have a sound knowledge of the pump and its operation.
Prohibited
•
Specified power only
Do not operate the pump on voltage which is not specified on the nameplate.
Failure to do so may result in damage or fire. Only the specified power level is to be
applied.
Prohibited
•
Do not run the pump dry
Do not run the pump dry (without liquid inside the pump). Heat generated as a
result of abrasion between elements inside the pump during operation without liquid
may damage the inside of the pump.
Prohibited
•
Do not wet or dampen
If an electric part or wiring gets wet with the liquid spilled over accidentally, a fire or
electrical shock may be caused. Install the system in a place free from liquid
spillage or leakage.
Do not wet or
dampen
•
Do not damage or change power cable
Do not scratch, damage, process, or pull the power cable forcibly. An extra load
onto the cable, such as heating the cable or placing something heavy on the cable,
may damage the cable and finally cause a fire or an electrical shock.
Caution
•
Ventilate
Poisoning may result during an operation which involves, toxic or odorous liquid.
Ventilate the operating site sufficiently.
Caution
•
Damaged pump
Never operate a damaged pump. A damaged pump may cause leakage or electri-
cal shock.
