1.3 Notes on possible property damage
NOTICE
!
Risk of regulator damage due to incorrectly attached slings.
Î Do not attach load-bearing slings to the actuator housing.
Risk of regulator damage due to unsuitable medium properties.
The regulator is designed for a process medium with dened properties.
Î Only use the process medium specied for sizing the equipment.
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.
Risk of leakage and regulator damage due to excessively high or low tightening
torques.
Observe the specied torques when tightening regulator components. Excessive tight-
ening torques lead to parts wearing out more quickly. Parts that are too loose may
cause leakage.
Î Observe the specied tightening torques (see 'Tightening torques' in Annex).
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.
