Manual Flush (RO Membrane)
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 Thermo Scientific 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.
Dispensing Water
Use the dispense knob for manual dispensing or press the DISPENSE switch for volumetric or timed
dispensing.
Automatic Dispensing
This feature is accessible from any screen when the volumetric dispensing icon is an available switch.

2. Press the volumetric dispensing icon.
The screen will show current settings for Remote Volumetric, Unit Volumetric, Timed Dispense or
OFF. Press MODE to choose setting and use the up and down arrows to set volume or time.

Thermo Scientific
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 Thermo Scientific
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.
