WARNING
•Be sure to connect ground wires to the connected piping and any other connected equipment.
For details, see the applicable operating caution on p. 4,5 and 6.
When the pump is operated without a ground wire or otherwise not properly grounded,
friction between parts and abrasion caused by some fluids flowing inside the casing may
generate static electricity. Also, depending on the type of fluid being pumped and the
installation environment (such as gases in the air or the surrounding fixtures), it may be a
cause of fire or electric shock.
