DANGER
!
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
WARNING
!
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
ries.
Î Allow components and pipelines to cool
down or warm up to the ambient tem-
perature.
Î Wear protective clothing and safety
gloves.
WARNING
!
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the

NOTICE NOTICE
! !
Risk of overheating due to excessive
ambient temperatures or insufficient heat
dissipation when components are insulated.
− Do not include the regulator in the insula-
tion of the pipeline.
NOTICE
!
Risk of impaired functioning of the regula-
tor and leakage at the joint due to installa-
tion under tension.
− Bolt the regulator to the pipeline free of
stress.
− If necessary, support the pipelines near the
connections.
− Do not attach supports directly to the valve
or control thermostat.
Before start-up or putting the device back in-
to service, make sure the following condi-
tions are met:
− The regulator is properly installed into
the pipeline (see the 'Installation' sec-
tion).
− The leak and function tests have been
completed successfully (see the 'Testing
the regulator' section).
− The prevailing conditions in the plant
section concerned meet the regulator siz-
ing requirements (see information under
'Intended use' in the 'Safety instructions
and measures' section).
