Special Instructions For Safe Use; Preparation For Use - Dräger Flame 2000 Notice D'utilisation

Aiming the flame detector

The flame detector should be aimed toward the center of the

detection zone and have an unobstructed view of the
protected area.
Whenever possible, the flame detector face should be tilted

down at a 45º angle to maximize coverage and prevent
accumulation of dust and dirt.
Do not start an installation unless all conceivable

considerations regarding detection location have been taken
into account.
3.2

Special instructions for safe use

Do not repair or modify the flamepaths of the flame detector.

The unit may be painted or fitted with optional accessories. Some

of these parts are made of a non-metallic material or have a non-
metallic coating which could potentially generate an ignition-
capable level of electrostatic charge under certain extreme
conditions (such as high-pressure steam). Do not damage the
coating and clean the equipment with a damp cloth only to prevent
a build-up of electrostatic charges on the non-conducting
surfaces.
The 3 fastening screws used to secure the cover of the flameproof

compartment have a yield stress of 344 N/mm². Any replacement
fasteners shall have a yield stress of at least this value.
