Wiring 110 & 220 Volt AC Versions
AC Systems will Have:
Fresh water flush cable, these wires have no polarity
Two Power inlet harnesses with terminal blocks,
A 75’(26 M) cable with connectors for the MPC-3000 control display,
Clark Pump Module harness consisting of the Rotoflow cable, salinity probe cable, and the
diversion valve (no polarity) cable.
The MPC-3000 Control box houses the
V ariable F requency motor D rive and the MPC-3000
control board. The VFD serves several functions. First it allows the machine to run with al-
most any AC frequency. Regardless of the input conditions the drive will hold a constant
motor speed. The motor controller output is three phase AC to the motor. The control will
“soft starts” the motor. This allows the watermaker to be run on a very small generator if
desired. The motor control also slows the motor to the flush and service speeds. The VFD
has over-temperature shutdown protection.
Do not install it in hot or poorly ventilated
locations.
