2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the differential
pressure regulator is used correctly.
Oventrop differential pressure regulators "Hydromat DFC"
are installed in heating and cooling systems with closed
heating circuits for an automatic differential pressure re-
gulation (hydronic balancing).
Any use of the control station outside the above applica-
tions 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 instruc-
tions is part of the compliance terms.
2.2 Possible dangers at the installation location and
during transport
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 ex-
ternal forces, e.g. as connection point for lever tools
etc.
Hot and cold surfaces
Risk of injury Do not touch the regulator 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 control station out
of reach of children.
Allergies
Health hazard Do not touch the dwelling station and
avoid any contact if allergies against the used materials
are known.
The case of an external fire has not been taken into con-
sideration when constructing the differential pressure re-
gulator.
