Maintenance

9.1

Overview

The VESDA VLF continuously monitors its own operation and conducts frequent health checks. There are
two serviceable items, the air filter cartridge and the aspirator.

Caution:

Electrostatic discharge precautions need to be taken prior to removing the front cover from the
detector otherwise damage may occur to the detector.

Attention :

Il convient de prendre des précautions contre les décharges électrostatiques avant d'enlever le
capot avant du détecteur, sinon l'appareil risque d'être endommagé.
