Introduction
On receiving the pump, promptly check the following items.
1. Confirmation of pump and accessories
1) Confirm non-occurrence of damages and of loosening of bolts and nuts, which may be generated
during transportation.
2) Confirm the presence of full-set of accessories.
(For the standard auxiliaries, refer to the section of 10 "Structure". )
２．Confirmation of nameplate
1) The nameplate gives basic specification of the pump. Confirm the specification of your pump on the
nameplate. Specifically, care shall be paid on the frequency (50 Hz or 60 Hz).
Caution
Do not operate a pump of 50Hz at 60Hz. The operation at wrong frequency
induces pump break caused by excess pressure and motor burn-out caused by
overload.
Do not operate a pump of 60Hz at 50Hz. The pump performance deteriorates.
