2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the propor-
tional flow controller is used correctly.
The proportional flow controllers are used in Oventrop
"Regudis W" dwelling stations for heating circuit con-
trol for hot water preparation via the heat exchanger
of the "Regudis W" stations according to require-
ments.
Any use of the proportional flow controller 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 in-
structions 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 fixed value con-
trol set.
WARNING
Hot and cold surfaces
Risk of injury Only touch with safety gloves. The
proportional flow controller can 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 small com-
ponents supplied with the proportional flow con-
troller out of reach from children.
Allergies
Health hazard Do not touch the proportional
flow controller and avoid any contact if allergies
against the used materials are known.
3 Transport, storage and
packaging
3.1 Transport inspection

3.2 Storage
The proportional flow controller must only be stored
under the following conditions:
– Do not store in open air, but dry and free from dust.
– Do not expose to aggressive fluids or heat sources.
– Protect the proportional flow controller from direct
sunlight and mechanical agitation.
– Storage temperature: -20 up to +60°C,
max. relative humidity of air: 95 %
3.3 Packaging
Keep packaging for a possible return of the propor-
tional flow controller.
