*1 Starting head of individual operation model is set for shallow well (-8m total suction head), and alternate/parallel operation is set for reservoir tank (-2m total suction head).

When using, adjust starting pressure setting according to applications.

*2 Operation head (reference) at 10L/min discharge. Operation head may vary according to the capacity in S mode.

NOTE) Operation head is not constant in S mode. Power consumption may increase at small capacity operation compare with E mode. *E mode is set as default.
