Section 4 Using Your TII
1. Turn the system power ON by depressing the main power switch to
the “I” position.
2. The system electronics will initialize and check its calibration. All units
have been factory calibrated.
3. The unit will enter STANDBY mode.
4. From STANDBY, press the START/STOP switch on the control panel
to enter the RUN mode. The unit’s RO pump will begin to run.
5. The display will then begin reading resistivity of the system product
water. Initially, it will read “PROCESSING” while the DI meter is
initializing. The DI section will not operate until the tank is 25% full.
6. Allow the water’s resistivity to rise to the desired purity before
dispensing water.
7. The system should be left in RUN during the workday.
8. If the Barnstead TII is to be shut down for an extended period of time,
the unit should be completely drained and the cartridges and
membrane(s) removed and refrigerated to prevent the growth of
bacteria.
The Barnstead TII is controlled through a panel that incorporates buttons
to control its functions. This control panel utilizes a graphical display to
show system information and the purity of the product water. The
intensity of the display may be adjusted according to user preference. Refer
to “Setting System Options.”
Warning Do not use in the
presence of flammable or
combustible materials; fire or
explosion may result. This
device contains components
that may ignite such materials.
