You can only install the VICI valve where a VICI valve drive is installed. To install the VICI valve drive, contact your local Thermo Fisher Scientific Technical Support. For an overview of the VICI switching valve, see Column Switching Valve Overview.
Prerequisite
The VICI valve drive and the adapter frame are installed (performed by service engineer).
Parts required
VICI switching valve
Tools required
Screwdriver, Torx T10
Follow these steps
To remove the cover plate, screw a fitting plug from the valve ports into the opening in the center of the cover plate.
With the screwdriver, loosen the 4 screws on the cover plate.
Pull out the cover plate by the fitting plug.
Do not yet remove the fitting plugs that cover the valve ports.
Align the two pins on the back of the valve lock ring with the matching openings on the valve flange.
Press the valve pod to the valve flange.
To align the axis with the valve pod, press and hold the VALVE LEFT button or the VALVE RIGHT button on the keypad depending on the valve position. The catch valve function is activated and you can release the button.
When the axis is aligned, the valve pod snaps into the valve flange.
Remove the fitting plugs that cover the valve ports.
Connect the liquid lines as required by the application.
Configure the VICI switching valve in the chromatography data system.
Inspect the valves visually for leakage.
Run the script: D02 - Test System Tightness (What Should Be Tested = Sampler). This script also tests the column switching valves for leakage.
