6. Analyzer safety and maintenance

This chapter describes the maintenance plan and instructions for the maintenance. Proper handling

and damage prevention are also explained. Read these instructions carefully to keep your analyzer in

good condition.

Improper handling of any components inside the analyzer may damage it. Thus, adjustment of any

components inside the analyzer voids the warranty. Any service operations that require opening the

case of the analyzer should be performed only by a trained service personnel. The case should only

be opened when the analyzer is turned off, battery pack, AC power cord and the gas lines are

disconnected/removed.

The user should pay attention to the following points:

> Every time after the measurements, the sample cell should be carefully flushed with nitrogen

gas or dry instrument air. If corrosive gases remain in the sample cell, the optics inside the

sample cell will be damaged. Measuring strongly acidic or caustic gases will irreversibly

damage the sample cell.

> If the sample gas contains solid particles, it should be filtered before introducing it into the

sample cell. Check regularly the filters you use and replace them when necessary to prevent

particulates entering the sample cell. If it is not filtered, dirt will accumulate in the sample cell

and lower the quality of the measurements. Any liquid droplets or aerosols inside the gas cell

may destroy sample cell mirrors or optical windows.

> After power has been switched off for a longer period or the unit is used in extremely humid

ambient conditions, it is recommended to purge the interferometer and sample cell with dry

nitrogen gas to avoid condensation on optical components.

> The pressure and temperature of the sample gas should always be kept as stable as possible.

However, the gas entering the sample cell should already be as close as possible to the

sample cell temperature.

> Intensive shocks may damage the analyzer. Be always very careful when you move or

transport the instrument.

> Use a soft cloth to wipe off the dirt on the case. Do not use strong detergents or acetone.

> Never replace Gasmet Power supply cord by an inadequately rated cord.
