LABS compatibility

The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.

*) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2cm below the

unit.

**) Do not energize in the presence of condensation.
***) Higher levels are allowed when using the 1606-XLC wall mounting bracket.
