Safety instructions and measures
1.3 Notes on possible property damage
NOTICE
!
Risk of regulator damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
Î
Flush the pipelines before start-up.
Risk of regulator damage due to the use of unsuitable lubricants.
The lubricants to be used depend on the regulator material. Unsuitable lubricants may
corrode and damage surfaces.
Î
Only use lubricants approved by SAMSON.
When in doubt, consult SAMSON.
Incorrect control due to the formation of ice on the regulator.
Medium temperatures below 0 °C may cause ice to form on the regulator, depending
on the air humidity. This may affect, in particular, the functioning of the plug or dia-
phragm stem guide.
Î
Prevent the formation of ice by taking appropriate precautions (e.g. enclosure,
trace heater etc.). The plant operator is responsible for selecting and implementing
appropriate precautions. See the 'Installation' section.
Risk of excess pressure damaging plant sections due to construction-related seat
leakage through the regulator.
Î
Always install a safety device (e.g. safety excess pressure valve or safety relief
valve) in the plant.
Risk of regulator damage due to unsuitable medium properties.
The regulator is designed for a process medium with defined properties.
Î
Only use the process medium specified for sizing.
