2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is
used correctly.
The double regulating and commissioning valves
“Aquastrom K” are straight pattern valves without de-
ad zone for use in cold water circulation systems. Hy-
dronic balance in a potable water circulation system
is guaranteed by the cold water circulation valve
“Aquastrom K”.
Any use of the valve outside the above applications
will be considered as non-compliant and misuse.
Claims of any kind against the manufacturer and/or
his authorised representatives due to damages cau-
sed by incorrect use cannot be accepted.
The observance of the installation and operating in-
structions is part of the compliance terms.
