Observe proper polarity as indicated on the controller.
• Connect controller “BATT” wires to the power
supply. Observe proper polarity as indicated on
the controller.
• Turn on power to the pump circuit.
• Allow water flow to purge air from the lines. System must be
completely purged.
• When air has been purged and a smooth flow is reached, close
each valve, one valve at a time. Gradually close the last valve.
• The control will auto-align itself to the pump in a few seconds.
The system is then ready to use.
