Troubleshooting

About this chapter

This chapter provides information required to enable users and service personnel to
identify and correct problems that may occur when operating Monitor UVis-920.

If the suggested actions in this guide do not solve the problem, or if the problem is not
covered by this guide, contact your GE representative for advice.

Precautions

WARNING

Before attempting to perform any of the procedures described in
this chapter, you must read and understand all contents of the
Safety instructions chapter.

WARNING

Hazardous chemicals or biological agents

. When using hazardous

chemicals or biological agents, make sure that the entire system
has been flushed thoroughly with bacteriostatic solution (e.g., NaOH)
and distilled water before service and maintenance.

WARNING

Electrical shock hazard

. All repairs should be done by service

personnel authorized by GE. Do not open any covers or replace
parts unless specifically stated in the user documentation.

CAUTION

Hazardous chemicals or biological agents in UV flow cell

. Make

sure that the entire flow cell has been flushed thoroughly with
bacteriostatic solution (e.g., NaOH) and distilled water, before service
and maintenance.
