2 Intended use
This device has been developed, designed and built for industrial
and commercial use only. The device is intended for operation
in closed rooms only. The steam generator is equipped with an
electrical resistance heating system and is used to generate water
steam for industrial and commercial purposes.
In general, the steam generator must only be filled with normal
softened or distilled water!
Only cold water must be used as the feedwater.
Additives must only be added to the feedwater with permission of
VEIT GmbH.
WARNING!
This device is exclusively designed for the purpose
mentioned above. Any other or further use as
well as any rebuilding or retrofitting of the device
without the written consent of the manufacturer will
be deemed as not in accordance with the intended
use. The manufacturer shall not be held liable for
damages caused by such use. The user alone
