Note: In North America, pump
and panel are pre-wired at the
factory for 120V. If alternate
voltage will be used consult
factory.
Wiring from the power supply
to the panel and pump must
be 12 AWG or larger to
maintain proper voltage under
full load conditions.
The circuitry for the panel and
pump is suitable for a 20AMP
circuit maximum.
