Assembly and Installation
3.2.3 Fitting the optional external purge air unit
Consider the following points when selecting the assembly location:
b 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 (
→ p. 31, §). In
unfavorable conditions, lay an air intake hose or pipe to a location with better condi-
tions.
b The fitting location must be easily accessible and meet all safety regulations.
b Install the purge air unit only as far as necessary below the flange with tube for the
sender/receiver unit and reflector so that the purge air hoses can be laid downwards
(avoids water collecting).
b Provide sufficient clearance to exchange the filter element.
b Provide sufficient space to attach and remove the weatherproof cover when installing
the purge air unit outdoors
