2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the differential
pressure regulator is used correctly.
The Oventrop differential pressure regulator is installed
in the return pipes of hot water central heating and
cooling systems to maintain a constant differential
pressure within a necessary proportional band.
Any use of the differential pressure regulator 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 storage cylinder.

WARNING
Heavy product!
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, pressure test points or actuators
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 differential pressure regulator 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 differential
pressure regulator out of reach of children.
Allergies!
Health hazard! Do not touch the differential
pressure regulator and avoid any contact if
allergies against the used materials are known.

during transit and completeness.
Any damage must be reported immediately upon
receipt.
3.2 Storage
The differential pressure regulator 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.
– Protect against external forces (e.g. impacts,
vibrations etc.).
