Check list

Go through the following points before beginning the installation of the LDS 6 laser gas analyzer
to make sure all preparations are completed.
• The flanges shall be welded to the wall of the furnace or funnel and properly aligned from
both sides.
• Make sure that the positions of the flanges are stable. The flanges fitted for the optics
housings must not deviate more than ±2°.
• Make sure that the flanges protrude at least 100 mm (4") from the wall and 0-30 mm (0-1.2")
into the furnace or funnel.
• There must be enough room for the optics housings to allow easy access for maintenance
and service.
• Make sure the path length is measured properly.
• Make sure that the environment where the central unit is to be installed has the right
temperature conditions.
• Make sure there is enough space to allow free airflow around the central unit (500 mm/20"
behind, 50 mm/2" above and 30 mm/1.2" below).
• Make sure the operating and installation temperatures for the hybrid and sensor connection
cables are not exceeded.
• Make sure the process flange has an inner diameter which allows the purging tube to be
adjusted ±2 deg. (The outer diameter is 44.5 mm for the 400 mm purging tube and 54 mm
for the 800 and 1200 mm purging tubes).
