Special Conditions for Safe Use:

1. Non-flame arrestor probe -"NF" versions must have the probe installed in a non-

classified area.

2. When the probe tube is mounted in a hazardous (classified) area (with flame

arrestor end to complete the assembly) calibration lines that travel in and out of the
equipment bringing reference gas must not contain a pressure higher than 1.1
times the atmospheric pressure; these calibration lines shall not contain pure
oxygen, acetylene, or combustible gases other than the gases for which this Zone 1
classified application has been investigated for: Group IIB +H2 gases.

3. There are no interchangeable components.

4. Contact the original manufacturer for information of flameproof joint dimensions.

5. Fastener property class must be A2-70 for units intended for use in Zone 1 classified

areas.

6. Any other electronics not covered by this report and used in conjunction with the

Rosemount

™

Oxymitter probes or with the remote electronics must be installed in a

non-classified area (ex. Rosemount Xi Advanced Electronics).
