Milli-Q Synthesis/Synthesis A10 61
Put the Milli-Q into PRE OPERATE Mode. Press the OPERATE/STANDBY Keypad Button for about
2 seconds. This will change the Milli-Q from STANDBY Mode to PRE OPERATE Mode. See the drawing
below for more information.
Move the POU Dispenser Trigger forward. This will place the Milli-Q in PRODUCT Mode.
Verify that you have several Litres of feedwater (i.e. full Reservoir or full Distribution Loop).
Bring the POU Dispenser Trigger down (towards you). You should hear a sharp ‘click’ noise. This is the
opening of the Inlet Solenoid Valve.
The LCD will change and will look like:
Let the AIR PURGE continue for its 5 minute duration. It will count down to 0 minutes (5, 4, .., 0 mn).
Pressurised Feedwater Only:
Check the Pressure Gauge on the Pressure Regulator. While water is flowing
through it, the Pressure Gauge should show 0.3 bar. If it is not set to 0.3 bar, then turn the round handle on the
Pressure Regulator clockwise until the pressure gauge (on the regulator) shows 0.3 bar. Check this again when
water is flowing through the Pressure Regulator.
The setting of the Pressure Regulator should not exceed 0.3 bar.
The feedwater pressure reaching the Milli-Q in PRODUCT Mode
should not exceed 0.3 bar. The Pressure Regulator should only be
set while water is flowing through it. It is perfectly normal to see an
increase in the Pressure Regulator setting while water is not flowing
through it (i.e. STANDBY or PRE OPERATE Mode).
The Milli-Q will now go to STANDBY Mode and will remind you to close the POU Dispenser Valve.
Move the POU Dispenser Trigger back (its upright position). The Milli-Q will now go to PRE OPERATE Mode.
