2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is
used correctly.
The regulating valve “Cocon 2TZ” is installed in heating
and cooling systems with closed water circuit (like fan
convectors (fan coil units), chilled ceiling modules,
induction air systems, cooling and heating zones etc.)
and serves to control the room temperature by varying
the flow rate with the help of actuators, thermostats
or temperature controllers. 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 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
and during transport
The case of an external fire has not been taken into
consideration when constructing the valve.
3 Transport, storage and
packaging
3.1 Transport inspection
Upon receipt check delivery for any damages caused
during transit and for completeness.
Any damage must be reported immediately upon
receipt.
3.2 Storage
The valve must only be stored under the following
conditions:
– Do not store in open air, keep dry and free from dust.
– Do not expose to aggressive fluids or heat sources.
– Protect from direct sunlight and mechanical agitation.
– Storage temperature: –20 °C up to +55 °C
– Max. relative humidity of air: 95 %
3.3 Packaging
Packaging material is to be disposed of in an
environmentally friendly manner.
WARNING
!
Heavy valve!
Risk of injury!
Wear suitable protective clothing (e.g.
safety shoes) during installation and use safety devices.
External components like handwheels or pressure
test points must not be misused for the absorption
of external forces, e.g. as carrying handle or connection
point for lever tools etc.
Hot or cold surfaces!
Risk of injury!
Do not touch without safety gloves.
The valve may get very hot or cold during operation.
Sharp edges!
Risk of injury!
Only touch with safety gloves. Threads,
bore holes and edges are sharp.
Small components!
Risk of ingestion!
Store and install the valve out of
reach of children.
Allergies!
Health hazard!
Do not touch the valve and avoid any
contact if allergies against the used materials are
known.
DANGER
!
Suitable measures (e.g. safety valves) have to be
taken to ensure that the maximum operating
pressures and the maximum and minimum operating
temperatures are not exceeded or undercut.
