WARNING
The process medium may be hot or otherwise hazardous. Precauons when removing the sensor
from the process line:
Make sure that the process line is not under pressure. Open a vent valve to the atmosphere. For a
retractor/isolaon valve the line pressure should be within specicaons.
For a prism wash system, close a hand valve for the wash medium and disable the wash valve. Loosen
the clamp or ange bolts cauously, be prepared to ghten again. Be out of the way of any possible
splash and ensure the possibility of escape.
Use shields and protecve clothing adequate for the process medium. Do not rely on avoidance of
contact with the process medium.
It is the user’s responsibility to follow manufacturer’s safety and operang instrucons. The client’s
organizaon has the responsibility to develop and maintain occupaonal safety and create a safety
culture where individuals are expected to follow safety instrucons at all mes. Any negligence to-
wards safety instrucons or failure to comply with safe pracces should not be tolerated. It is the
manufacturer’s responsibility to produce goods that are safe to use when instrucons are followed.
