Limited operating site and storage
Do not install or store the pump in the following places:
* Flammable gas or material is used or stored.
* Ambient temperature is extremely high (40 dig.C or
higher) or extremely low (0 dig.C or lower).
•
Do not place the pump close to water
The pump is not water-proof construction. If the pump
is used in a place where liquid is splashed on pump or at
humid place, electrical shock or short-circuit may happen.
•
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.
•
Arrange grounding
Be sure to connect grounding wire before operation.
Otherwise, an electrical shock may result. Make sure the
grounding wire is connected with the grounding terminal.
•
Install an earth leakage breaker (option)
Pump operation without using an earth leakage breaker
may cause an electrical shock. Purchase an optional leak-
age breaker and install in the system.
