Installation
10. Slowly open the shut-off valves in the
pipeline after the valve has been in-
stalled.
5.3.2 Cleaning the pipeline
We recommend additionally ushing the
pipeline with installed regulator before start-
up.
Î Unscrew the control line (18) from the
valve body.
Î Seal the valve body with stoppers.
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.
If the regulator malfunctions due to clogging
after ushing the pipeline, proceed as de-
scribed in the 'Troubleshooting' section.
5.4 Testing the regulator
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure
equipment that may burst when handled
incorrectly. Flying projectile fragments or the
release 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 Disconnect the control line.
Î Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of fatal injury due to electric shock.
Î Upon installation of the electric cables,
you are required to observe the regula-
tions concerning low-voltage installations
according to DINVDE0100 as well as
the regulations of your local power sup-
plier.
Î Use a suitable voltage supply which
guarantees that no dangerous voltages
reach the device in normal operation or
in the event of a fault in the system or
any other system parts.
Î Only perform the electrical connection
after switching off the supply voltage.
Make sure the supply voltage cannot be
switched on again unintentionally.
