2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the valve is used
correctly.
The pressure independent control valve "Cocon QFC/QGC"
is designed to be installed in heating and cooling systems
with a closed water circuit (e.g. central or underfloor heating
systems, 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 QFC/QGC" outside of 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 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
Heavy valve
Wear safety shoes to protect your feet during installation
Hot surfaces
The valve may get very hot during operation. Do not touch
without safety gloves.
Sharp edges
The valve's threads are sharp. Do not touch without safety
gloves.
Small pieces
Store and install the valve out of reach of children.
Allergies
Don't touch the valve and avoid any contact if allergies
against the used materials are known.
The case of an external fire has not been taken into consi-
deration when constructing the valve.
