Risk of personal injury due to process me -
dium escaping.
Î
Do not start up the regulator and control
thermostat until all parts have been
mounted.
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
Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of burn injuries due to hot or very cold
components and pipelines.
Depending on the process medium, the regu-
lator and pipelines may get very hot or cold
and cause burn injuries.
Î
Wear protective clothing and safety
gloves.

5.4.1 Leak test
The plant operator is responsible for per-
forming the leak test and selecting the test
method. The leak test must comply with the
requirements of the national and internation-
al standards that apply at the site of installa-
tion.
SAMSON's After-sales Service can support
you to plan and perform a leak test for your
plant.
1. Slowly open the shut-off valve installed
upstream of the sensor.
2. Apply the required test pressure.
3. Check the screw gland of the sensor or
thermowell for leakage.
4. Depressurize the pipeline section where
the sensor is installed.
5. Rework any parts that leak and repeat
the leak test.
