… 5 Preparation for Installation
Backpurging Unit
Design of the back-purging unit
The back-purging unit consists of a protective cabinet with shut-
off valve, 6 bar pressure reduction valve, solenoid valves for
back-purging, pressure regulator and 2 l compressed air receiver
(pressure buffer tank) for effective pressure pulses also with
lower airflow rate.
Distance to sampling probe
The distance between the back-purging unit and the sampling
probe should be as short as possible and must not exceed 2 m
(6.6 ft).
Protection from adverse ambient conditions
Protect the back-purging unit against:
• Water spray
• Contact with chemicals
• Strong sunlight and heat radiation
• Strong air currents
• Heavy dust load
• Corrosive atmospheres
• Vibration
Instrument air supply

NOTICE
Damage to the sample conditioning components
If the compressed air is not dry and clean, this will result in
damage to the sample conditioning components (valves,
filters, sample gas cooler, sample gas feed unit) as well as to
the gas analyzer.
• Only use dry and clean compressed air.
