Required materials

• Protective eyewear

• Chemical-resistant, powder-free gloves

• 9/16-inch hex wrench, supplied with the ACQUITY Diverter Valve Assembly Kit

• Rotor seal

• Stator (Stainless steel or Titanium)

To replace the ACQUITY diverter valve stator and rotor seal:

Stop the flow from the LC, ensure that the QDa detector is in standby mode, and
disconnect the power cable from the diverter valve.

Disconnect the fluidics tubing from the stator on the front of the diverter valve.

Use the 9/16-inch hex wrench to unscrew the 3 retaining bolts and remove the stator.
