Instruction manual

A four minute manual flush of the RO membrane can be initiated through
the RO Options in the MENU. During the four minute flush, water is
sent to drain through the drain tubing and the display will show remaining
minutes. After the timed flush has ended, the Barnstead TII will return to
the mode (IDLE, RUN or STBY) it was in when you initiated the flush.
To initiate a flush:
1. Choose MENU and scroll to RO Options. Press OK.
2. Choose Manual Flush and press OK.
Use the dispense knob for manual dispensing or press the DISPENSE
switch for volumetric or timed dispensing.
This feature is accessible from any screen when the volumetric dispensing
icon is an available switch.
Note When “UNIT UNDER COUNTER” is set to “ON,” Auto Dispense
will not be available from the main unit dispenser although the manual
dispense knob will work. Volumetric dispensing is based upon total fluid
volume entering the Barnstead TII. Point of dispensing accuracy will be
compromised if you are dispensing water volumetrically while
simultaneously dispensing water manually through the remote dispenser
accessory. Once Volumetric or Timed Dispensing values are set, they will
remain in memory until changed by the user. To turn the dispense method
OFF, select “OFF” in the “Dispense Method” menu.
