- Design number was changed from 10 to 11D since the unipump was switched to the energy-saving type. (Installation compatible with previous unipump)
 - Contact us if a combination other than those in the above table is used.
 - Rotational direction is clockwise when viewed from the electromotor fan.
 - For the electromotor, three rated voltages (AC200-50/60 and AC220-60Hz) are standard for each size (0.75 – 2.2kW-4P).(Different voltages are also available.)
 - Protective structure of electromotor: main body: IP44; terminal box: IP54.
