4.6 Column Compartment

4.6.1 Installing a Column Switching Valve

The following column switching valves are available:
Column Switching Valve
2-position, 6-port switching valve
2-position, 10-port switching valve
1. Do not touch any metal or plastic parts inside the column chamber while the
temperature is higher than 50 °C. Before carrying out any work in the column
compartment, wait for the column chamber to cool down.
To shorten the cool-down time, consider setting a lower temperature and opening the
front panel door.
2. A lever is provided on the enclosure bottom of the column compartment for pulling
forward the valve actuators. Turn the lever to right and pull it toward the front as far as
it goes out.
Tip: Closing the front panel door will move the lever, and thus the actuators
automatically backward.
3. Align the two pins on the back of the valve with the matching openings on the
actuator.
