MAINTENANCE

7.1 OVERVIEW
7.2 REPLACEMENT PARTS

7.1 OVERVIEW

The Solu Comp II analyzer needs little routine maintenance. The calibration of the analyzer and sensor should
be checked periodically. To recalibrate the analyzer and sensor, see Section 6.0.

Clean the analyzer case and front panel by wiping with a clean soft cloth dampened with water ONLY. Do not
use solvent, like alcohol, that might cause a buildup of static charge.

7.2 REPLACEMENT PARTS

Many components of the analyzer are replaceable. Refer to the table below to find the correct parts diagram.
