2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is used
correctly.
The combined control and regulating valve "Cocon QTR" is
designed to be installed in heating and cooling systems with
a closed water circuit (e.g. central or underfloor heating sys-
tems, fan coil units, chilled ceilings, fan convectors etc.).
It operates as an automatic flow and differential pressure
independent control (hydronic balancing) and can control
another variable (e.g. room thermostat) by modifying the
flow rate in conjunction with actuators.
Any use of the "Cocon QTR" outside of the above applica-
tions will be considered as non-compliant and misuse.
Claims of any kind against the manufacturer and/or his
authorised representatives due to damages caused by
incorrect use cannot be accepted.
The observance of the installation and operating instructions
is part of the compliance terms.
2.2 Possible dangers at the installation location
The case of an external fire has not been taken into consi-
deration when constructing the valve.
