In STANDBY Mode, the DI pump will operate for ten minutes out of
every hour (i.e 50 minutes off, 10 minutes on). Every fourth time that the
pump turns on, the UV lamp will also turn on for 10 minutes (i.e 3 hours
50 minutes off, 10 minutes on). This will allow the unit to produce high
quality water quickly upon being placed in the RUN Mode. It is
recommended that the TII be placed in STANDBY mode during non-
work hours. At the end of the work day, press the STANDBY switch to
place the unit in STANDBY mode. Also, in STANDBY mode, the RO
operation automatically turns on to fill the reservoir as needed, and the RO
system returns to STANDBY once the reservoir is filled.
Note Each time the RO system automatically turns ON, in RUN or
STANDBY mode, the RO membrane will flush water to the drain for 30
seconds prior to filling the reservoir.

Note If the unit is in STANDBY and power to the unit is turned off or
lost, the unit will return to STANDBY once power is restored.

In the Standby Mode, the Thermo Scientific TII will initiate a four minute
automatic flush of the RO membrane once every three hours and fifty-six
minutes of operation. This prevents buildup on the RO membrane. A
timer in the TII counts the hours power is applied to the unit. When the
timer reaches three hours and fifty-six minutes, the TII initiates a four
minute flush if the unit is in the RUN or STANDBY Modes. If the unit is
in IDLE, the automatic flush will occur immediately after the
START/STOP switch is pressed and RUN Mode entered. The timer will
reset to zero when the four minute automatic flush is completed.
Note Press the START/STOP switch to cancel a flush.
