Safety Precautions

SAFETY

PRECAUTIONS

WARNING: Remove power from the pump before attempting any

maintenance.

Remove power from the pump before any cleaning operation is started.

Repeatedly applying AC line power to the drive as a means of starting the pump can cause drive hardware damage and will void the warranty. Use the control inputs located on the 9 pin connector to start and stop the pump; this will dramatically reduce the current surge associated with starting the pump. Replace the power cord only with one of the same type and rating. The minimum power ratings are stated on the rear panel.

WARNING: To prevent damage to pump, do not restrict pump inlet or run

the pump dry.

CAUTION: When changing ﬂow direction, allow the pump to come

to a complete stop before starting again. Failure to do so could cause permanent damage to the motor.

Replace the fuse only with one of the same type and rating. The fuse rating and type are stated on the rear panel.
