Cleaning The Pipeline; Testing The Regulator - Samson EB 2111 Translation Of Original Instructions

Installation

5.5 Cleaning the pipeline

We recommend additionally flushing 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 flushed and clean it, if neces-
sary.
Î Before flushing the plant, open all con-
sumers to guarantee a high flow rate.
If the regulator malfunctions due to clogging
after flushing the pipeline, proceed as de-
scribed in the 'Troubleshooting' section.

5.6 Testing the regulator

DANGER
!
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.
WARNING
!
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.
