2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the valve is used
correctly.
The Oventrop three-way diverting valve “Tri-D TR” is
used for diverting 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.
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 or pressure test points must not be
misused for the absorption of external forces, e.g.
as connection point for lever tools etc.
Hot or cold surfaces!
Risk of injury! Do not touch the valve without
safety gloves. It may get very hot 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.
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 three-way diverting 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 material
Packaging material is to be disposed of environmentally
friendly.

DANGER
!
Suitable measures (e.g. safety valves) have
to be taken to ensure that the maximum
operating pressures and maximum and
minimum operating temperatures are not
exceeded or undercut.
