4.1 SAFETY

INSTRUCTIONS

The personnel must observe all safety instructions at all times.

When operations need to be carried out on the analyzer, cut off the power supply sources as
much as possible.

Take the necessary precautions for the manipulation of dangerous products such as gases
under high pressure (put the bottles in a rack in a ventilated room).

Frequently check that there are no leaks in the pipes.

Competent personnel only is allowed to carry out operations on the analyzer.

Concerning safety, the manufacturer disclaims his responsibility in case of:

–

unqualified personnel using the analyzer,

–

use of the analyzer under conditions other than those specified in this document,

–

modification of the analyzer by the user,

–

negligence of maintenance on the analyzer.

A systematic and periodical inspection visit is essential.

REMINDER

Before switching off the analyzer, it is strongly recommended to switch it
on zero mode for at least 5 minutes. The monitor can be permanently
damaged by the corrosive gas in the measurement chamber when the latter
is unheated.
