Installation
5.5 Cleaning the pipeline
Werecommendadditionallyushingthe
pipeline with installed regulator before start-
up.
Î Observethemeshsizeoftheupstream
strainerforthemaximumparticlesize.
Use strainers to suit the process medium.
Î Checkthestrainerfordirteachtimethe
pipelineisushedandcleanit,ifneces-
sary.
Î Beforeushingtheplant,openallcon-
sumerstoguaranteeahighowrate.
If the regulator malfunctions due to clogging
afterushingthepipeline,proceedasde-
scribed in the 'Troubleshooting' section.
5.6 Testing the regulator
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure equip-
ment that may burst when handled incor-
rectly. Flying projectile fragments or the re-
lease of process medium under pressure can
cause serious injury or even death.
Before working on the regulator:
Î Depressurize all plant sections concerned
and the regulator.
Î Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Incorrect opening of pressure equipment or
mounting parts may lead to the process me-
dium escaping to the atmosphere.
Î Do not loosen the control thermostat
while the valve is pressurized.
Î Do not start up the regulator until all
parts have been mounted.
