M Millenium™ RO System by GE Osmonics
14693e – 31 Mar 03 1 - 10 General Information
Product Port:
The Product Port is a quick-disconnection port for the output of purified product
water. The port has a check valve that closes when there is no hose connected to
the fitting.
Waste Port:
The Waste Port is a quick-disconnection port for the output of concentrate or waste
to the drain. The port has a check valve that closes when there is no hose connected
to the fitting.
Percent Rejection Display:
The Percent Rejection Display is a 5 LED array that indicates how the RO
membranes are performing. The lights correspond to 99%, 95%, 90%, 85%, and
>70% rejection. The 99% light, when illuminated, indicates a need to evaluate the
RO system performance. RO units do not normally perform in excess of 99%;
verify this reading with an independent meter and take corrective action if
indicated. Some RO membranes will achieve this level of performance under
optimum conditions.
Product Water Total Dissolved Solids (TDS):
The Product Water Total Dissolved Solids (TDS) digital display indicates product
water purity in mg/L (ppm). It is temperature compensated to adjust the value of the
display with changing water temperature for better accuracy.
Less Than 0.5 mg/L Check System Lamp:
The Less Than 0.5 mg/L Check System lamp illuminates when the TDS reading is
0.5 mg/L or less. This indicates a need to evaluate the RO system performance.
RO units do not normally have this low product TDS. Verify this reading with an
independent meter and take corrective action if indicated. RO membranes may
achieve this level of performance under optimum conditions (good feed water).
Alarm Set:
The Alarm Set switch allows the operator to set the TDS levels at which the alarm
will sound. The alarm should be set at twice the initial TDS reading. If the set
point is exceeded, an audible alarm will sound.
Alarm Mute:
The Alarm Mute switch will mute the audible alarm for 30 - 45 seconds. A red
indicator lamp is displayed on the switch when the mute switch has been pressed.
