Warning
In case of emergency operation a rapid-action closing of the bottom valve
is not possible.
When the emergency operation of one or both bottom valves is finished,
find and eliminate the cause for the malfunction. Note that the repeated or
continuous application of the emergency operation is considered as
improper usage. The resulting risk will have to be borne by the user alone.
The manufacturer hereby expressly rejects any claims for any resulting
damage.
