3.1 OPERATION
Once the system has been started, the SRO will continue to make water until the float switch
is tripped upon high water level in the storage tank. At this point, the SRO will be placed into
standby (tank full) until the water in the storage tank reaches a low-level to open the float
switch. Once the float switch opens, the SRO will re-initialize and begin to produce water
again. In the event that the TDS is above the pre-determined set-point, the alarm lamp will
light and the HI TDS warning message will show on the display. This warning will clear when
the TDS drops below the Setpoint.
The DI polishes the water from the RO. The DI continues to polish the water until the
resistivity light senses that the incoming water is above the threshold value of 200,000 ohm.
At which point, the resistivity light will turn red showing a warning of the water quality being
above the pre-determined set-point of 200,000 ohms.
The Endotoxin filter will remove endotoxins from the feed water, sending the filtered water to
the loop.
