3 ASSEMBLY AND INSTALLATION
3.2.3 Fitting the optional external purge air unit
Consider the following points when selecting the assembly location:
▸ Install the purge air unit at a location with clean air whenever possible. The air intake
temperature must correspond to specifications in the Technical data (see “Technical
Data”, page 111). In unfavorable conditions, lay an air intake hose or pipe to a location
with better conditions.
▸ The fitting location must be easily accessible and meet all safety regulations.
▸ Install the purge air unit only as far as necessary below the flange with tube for the
sender/receiver unit and reflector/scattered light receiver so that the purge air hoses
can be laid downwards (avoids water collecting).
▸ Provide sufficient clearance to exchange the filter element.
▸ Provide sufficient space to attach and remove the weatherproof cover when installing
the purge air unit outdoors see “Purge air unit layout and assembly dimensions (dimen-
sions in mm)”, page 41).
