WARNING
Escaping aerosols can be toxic and pose a health hazard.
Residual air flows out of the device via the exhaust air outlet.
If hazardous aerosols are used and the exhaust air outlet is open,
these aerosols can get into the environment and harm persons.
► If hazardous aerosols are used: Verify that the exhaust air outlet is
connected to a suitable filter or cleaning system via the exhaust air
tube connector.
