-
indication of current water grade (superscript) and water conductivity (precise
readings of water quality are shown when the system is in Running, Grade I
dispense or Recirculation mode);
-
water temperature and filter life counter.
5.3.
If the system is equipped with TOC (total organic carbon) level monitoring module,
display shows TOC reading (e. g. <2 ppb). TOC level reading will be shown only
after the storage tank is at least partially filled with water and recirculation stage has
started.
5.4.
The purified water quality is controlled by two sensors. First sensor (Fig. 1/11)
measures and displays conductivity of Grade II water, flowing into or recirculating in
the storage tank. Second sensor (Fig. 1/19) measures and displays conductivity of
Grade I water that is dispensed at the moment.
5.5.
Indication in superscript next to the conductivity can take values “1” or “2”, showing
current water grade.
5.6.
To fill the tank with purified water, press and hold the
Run
key (Fig. 4/8) for 2
seconds. If tank is neither full nor disconnected and the feed water pressure is
enough, the display shows “Running”. Now the Labaqua system is filling the tank
with Grade II water. As soon as the tank is full, the system shuts down the water
supply and shows the “TnkFull” message.
5.7.
To dispense Grade I water, press
Pump Grade I
key (Fig. 4/6). After five to ten
seconds, Grade I water is dispensed through the 0.22
μm filter. If ultrafilter is
installed, loosen the degassing valve to get rid of air. Press the
Pump Grade I
key
again to stop water dispensing.
5.8.
To dispense Grade II water from the tank, press the
Pump Grade II
key (Fig. 4/7).
To stop dispensing, press the
Pump Grade II
key again.
5.9.
System will circulate water on periodical basis to prevent growth of microorganisms
in the tank. During recirculation phase, the reading of Grade II water is shown on
the display. For the systems with TOC monitoring module, display shows TOC
reading in ppb. TOC reading appears in the left bottom display when purified water
storage tank is full and recirculation stage starts.
5.10. Recirculation is switched off when the system is in the Standby mode. To prolong
life of polishing module, please set the system to the Standby mode if it is not used
for long time (e.g. for the night).
5.11. Press
Run
key to toggle Standby mode on and off.
5.12. If feed water pressure falls, the
display indicates “LowPres”.
Note:
To actuate a key, press and hold it for two seconds.
