Water pump performance
The water pump is three speed-adjustable (Maximum / Medium / Minimum), so it may be required
to change default water pump speed in case of noise by water flow. In most case, however, it is
strongly recommended to set speed as Maximum.
Water pump speed
To secure enough water flow rate, do not set water pump speed as "Min."
Max. : high speed setting
Med. : low speed setting
Warning : Selecting a water flowrate outside the
curves can cause damage to or malfunction
of the unit.
: Operation cutoff range
