5.4 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 compressed medium can cause seri-
ous injury or even death.
Before working on the regulator:
Î Depressurize all plant sections affected
and the regulator.
Î Disconnect the control line.
Î Drain the process medium from all the
plant sections affected as well as the
valve.
Re
Risk of personal injury due to process me-
dium escaping under pressure.
Î First start up the regulator after mounting
all parts.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or ashing)
may occur during operation caused by the
process medium and the operating condi-
tions.
Î Wear hearing protection when working
near the regulator.

WARNING
!
Crush hazard arising from moving parts.
Î Do not insert hands or ngers between
the set point springs while the regulator
is in operation.
Î Do not insert hands or ngers between
the pillars and set point springs while the
regulator is in operation.
Î Do not insert hands or ngers between
the spring plate and crossbeam while the
regulator is in operation.
Î Before starting any work on the regula-
tor, depressurize plant sections as well as
the regulator.
Risk of burn injuries due to hot or very cold
components and pipelines.
Depending on the process medium, valve
components and pipelines may get very hot
or cold and cause burn injuries.
Î Wear protective clothing and safety
gloves.
SAMSON regulators are delivered ready for
use. To test the regulator functioning before
