Installation Guide

Section 5 Maintenance

5.1 Preventive Maintenance

The system requires preventive maintenance for safe and
reliable operation. Refer to the schedule below for the
minimum periodic maintenance requirements.

As Needed

– Perform these tasks as conditions require:

• Cleaning (section 5.2).

• Quick flow cell cleaning when recommended by a system

alert message (section 5.4.2).

Every Run

– Allow the separation run to finish with a high

percentage of solvent B to flush residual compounds from the
column, internal tubing, and flow cell. Refer to section 5.4.1.

Nightly

– Log off the system (File> Log out) and place the

On/Standby switch in Standby.

Monthly

– Perform these tasks at least monthly, more

frequently if conditions warrant:

• Tubing Inspection (section 5.3).

• Collection rack and tray cleaning (section 5.2.1).

• Monthly flow cell cleaning (section 5.4.3).

5.2 Cleaning

To clean the exterior surfaces, use distilled water with a mild
detergent. Use isopropyl alcohol for tougher stains.

On printed areas such as labels, avoid rubbing vigorously or
using aggressive solvents like acetone. Each will ruin the
printed text.
