7.2 Dispensing Ultrapure Water
Water can be dispensed manually, volume-controlled or time-controlled.
When dispensing product water, pay attention to the following aspects:
t Prior to dispensing the water, remove the protective cap on the bell
assembly of the final filter.
t After dispensing the water, replace the protective cap back on the bell
assembly.
For applications that require a very low content of organic material before
dispensing any water, remove 50 to 100 mL of water from the system (this
corresponds to the volume of the supply to the final filter and the final filter
capsule).
If the tank fill level is too low (< 2 L), ultrapure water dispensing will stop and
the following will be displayed for 3 seconds. Once the tank fill level rises to
more than 5 liters, the tank filling will stop and ultrapure water can be
dispensed.
7.2.1 Manual Dispensing
Manual dispensing is performed directly using the dispense slider on the
right side of the display.
With your fingers, you can use the slider to continuously regulate the
volume flow of the product water.
t Place your finger in the recess of the slider and move it downwards to
elevate the volume flow.
t Use your finger to move the slider upwards to lower the volume flow.
t Additionally, you can stop the dispense routine by tapping at the top of
the slider (on the crossed-through drop symbol). You can set the flow to
the maximum volume by tapping on the bottom of the slider (on the
3-drop pyramid symbol).
y By touching the slider in the middle, you set the average volume flow.
The volume flow may vary depending on temperature as well as age and
condition of the cartridges and | or the connected Arium
®
Bagtank (Arium
®
Bagtank without pump).
Example:
Manual dispensing with the maximum flow volume.
t Stop dispensing by tapping on the top of the slider (crossed-through
drop) or by pressing the “Dispense” (R) “
Stop
” key.
