* 1 The products with model name ending “-e” are equipped with a Top Runner efficiency (equivalent to
IE3) motor.
* 2 Fresh water: 5.8-8.6 pH water without any contaminants (slurry and solids) and of which chloride ion
concentration does not exceed 200 mg/L. The water containing chloride ion exceeding 200mg/L may
cause corrosion. If the water contains a large amount of corrosive ions, it might not be used for the
product.
* 3 The total suction head shows the values when the water temperature is 20 °C. The maximum value
of the total suction head decreases when the pump is used with warm water. The total suction head
shows the sum of suction height and suction pipe resistance.
* 4 Limit the fluctuations of the power voltage within ±10% of the rated voltage, and also limit the
fluctuations of the frequency between –5% and +3% of the rated value. Avoid continuous operation if
the voltage is not within ±5% of the rated value or if the frequency is not within ±2% of the rated value.
