Milli-Q Synthesis/Synthesis A10 60
6-3 HOW TO REPLACE THE QUANTUM CARTRIDGE
The Quantum Cartridge is replaced whenever the Q-Gard Pack is replaced. This is important for maintaining
optimum water quality.
Follow the steps below to replace the Quantum Cartridge.
Removing the Quantum Cartridge from the Milli-Q
Make sure the Milli-Q is in STANDBY Mode. See Section 5-1 for more information if necessary.
Since the Q-Gard was just replaced (see Section 6-2), it is not necessary to release the residual water pressure
in STANDBY Mode.
Open the top and bottom latches of the door on the front of the Milli-Q system cabinet. Fully open the door.
Remove the Quantum Cartridge from the Milli-Q.
Installing a new Quantum Cartridge
Remove the Quantum Cartridge from its shipping box. Confirm that you have the desired type of Quantum
Cartridge by viewing the label on the Quantum Cartridge.
Remove the 2 plastic covers on the ports of the Quantum Cartridge. There should be a black rubber O-ring in
each port. Make sure these are pushed firmly in place.
Wet the Quantum Cartridge O-rings with water. It is preferable to wet them with Ultrapure Water. DO NOT
WET THE O-RINGS WITH A LUBRICANT SUCH AS OIL OR SILICON GREASE.
Push the Quantum firmly into place. Both the top and bottom ports of the Quantum Cartridge have to be fully
seated.
Close the door.
Make sure that both the top latch and the bottom latch of the door
are fully closed. Each latch should ‘click’ when it is fully closed.
The Quantum Cartridge is now installed.
You now need to perform an AIR PURGE with the Milli-Q system in order to remove
all air from the newly installed Q-Gard and Quantum.
Remove the used Millipak from the POU Dispenser.
Locate the clear Tygon Tubing and the Barbed Fitting from the Accessories Bag.
Screw the Barbed Fitting onto the bottom end of the POU Dispenser.
Do not use any Teflon Tape on the threads of the Barbed Fitting.
An O-ring is located inside the POU Dispenser to insure water tightness
between the threads of the POU Dispenser and the Barbed Fitting.
Push one end of the Tygon Tubing onto the end of the Barbed Fitting. Place the other end of the Tygon Tubing
into a sink.
At this time you should have installed the Q-Gard Pack, Quantum Cartridge, Barbed Fitting and the Tygon
Tubing. The system power should be on. The POU Dispenser Trigger should be upright. The LCD should be
showing STANDBY.
