Maintaining the column compartments 133
Replacing the column stabilizer assembly (CH-A only)
Use the column stabilizer only with the column heater (CH-A). Do not use it
with the column manager or auxiliary column manager.
Required materials
• Gloves: clean, powder-free, chemical-resistant
• Replacement column stabilizer assembly
Required tools
• 1/4-inch open-end wrench
• 5/16-inch open-end wrench
• Phillips screwdriver
To replace the column stabilizer assembly:
1. Stop any currently running mobile phase before replacing the column
stabilizer assembly.
Warning: To prevent burn injuries, set the column temperature to Off,
and then allow the column compartment and its components to cool for
60 minutes before touching them. Monitor the column compartment
internal temperature to ensure all components are cool.
Warning: To prevent electric shock, ensure all waste line tubing is
properly connected, and the drip tray is fitted and undamaged. Properly
installing the tubing and drip tray keeps waste or solvent from
contacting the power cord or cables.
Caution: To prevent contaminating system components, wear clean,
chemical-resistant, powder-free gloves when replacing the column
stabilizer assembly.
