This special monitorwill either be contained in a blue box or will be part of the printed circuit board and located within the electricalcontrol cabinet.This Voltage Monitor senses a voltage increase or decrease across the percent output ineter electricalshunt as the conductivity in the recycle tank changes as the salt content is converted to sodium hypochlorite orthe conductivity is raised due to salt injection to the tank via the brine pump. When the conductivity is belowthe design parameters the Voltage Monitor switches the brine pump "ON", injecting concentrated salt brine intothe recycle tank until the conductivity is increased to the proper level at which time the pump is switched off.The Voltage Monitor is preset at the factory and under normal circumstances should not be touched.During the initial start-up, salt and water are added to the holding tank manually and only enough salt shouldbe added to bring the percent output meter up to the 85% mark with the brine pump in the "ON" position.
