7.2. Connecting the ground wire
a) When installing the conductive pump, be sure to connect the ground wire at the specified position.
b) Ground wires should be connected to peripheral equipment and piping as well.
c) Use 2.0 mm
2
minimum ground wire.

Connection
8.1. Connecting fluid piping
1) Connect a flow valve and a drain valve to the fluid discharge port of the pump.
2) Connect a valve for maintenance to the fluid suction intake port of the pump.
3) Connect a hose to the valve on the suction-port side and the valve of the discharge-port side of the pump.
4) Connect a hose on the suction-side intake and the discharge-port side to the respective vessels.

WARNING
Ground wires must be connected to the piping and any other peripheral equipment. When operating the
pump make sure it is properly grounded. Otherwise friction between the parts and abrasion caused by
some fluids flowing inside the casing may generate static electricity. In addition it may cause fire or
electric shock, depending on the type of fluid being pumped and the installation environment (such as
gases in the air or the surrounding mixtures).
