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.
