2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is
used correctly.
The three-way mixing valve “Tri-M TR” is used for
mixing or changing-over of volume flows in heating
and cooling systems.
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.
3.2 Storage
The three-way 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 +60 °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!
Suitable transport and lifting devices
are to be used. Wear suitable protective clothing (e.g.
safety shoes) during installation and use safety devices.
External components like handwheels 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.
4.2 Materials
Valve body made of corrosion resistant bronze, inner
parts made of brass and stainless steel, seals of the
valve insert made of EPDM.
3 Transport, storage and
packaging
3.1 Transport inspection
