4 Mounting, installation and maintenance
Only use the devices as built-in units!
If the cooling air is polluted (dust, lint, greases, aggressive gases), adequate countermeasures have to be implemented.
These for instance can be:
•Separate air guide
•Mounting of filters
•Regular cleaning according to environmental conditions
The required minimum distance between the fan of the housing and adjacent parts is 20 mm, as described in the dimensional drawings.
