2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the valve isused correctly. Double regulating and commissioningvalves are installed in hot water central heating andchilled water A/C systems with a closed water circuitand serve to achieve a hydronic balance between thevarious circuits of the system.
Any use of the valve outside of the above applicationswill be considered as non-compliant and misuse.Claims of any kind against the manufacturer and/or hisauthorized representatives due to damages caused byincorrect use cannot be accepted.
The observance of the installation and operatinginstructions is part of the compliance terms.
