GAS 222.31 Ex2 2.2 General Hazard Warnings The maximum surface temperatures of the probes also vary based on operating conditions (steam temperature, sample gas in- let temperature, ambient temperature, fluid flow rate). When used in explosive areas, also particularly note the related hazard warnings.
GAS 222.31 Ex2 DANGER Toxic, corrosive gas/condensate Sample gas/condensate may be hazardous to health. a) If necessary, ensure a safe gas/condensate discharge. b) Always disconnect the gas supply when performing maintenance or repairs. c) Protect yourself from toxic/corrosive gasses/condensate when performing mainten- ance.
GAS 222.31 Ex2 3 Transport and storage Only transport the product inside the original packaging or a suitable alternative. The equipment must be protected from moisture and heat when not in use. They must be stored in a covered, dry and dust-free room at a temperature between -20 °C to 50 °C (-4 °F to 122 °F).
GAS 222.31 Ex2 4 Installation and connection NOTICE Accessories may limit critical operating parameters of the base unit Adding accessories may limit critical operating parameters. Ambient temperatures, zone classifications, explosion groups, temperature classes or chemical resistances of ac- cessories may vary from the base unit.

GAS 222.31 Ex2 6 Maintenance – Damaged parts must be replaced immediately. – Regularly check the function of the electrical protection. During maintenance, remember: – The equipment must be maintained by a professional familiar with the safety requirements and risks.
GAS 222.31 Ex2 CAUTION Drive pressurised Never loosen or remove the cover or any accessories with the drive pressurised. CAUTION Never open the drive with the function “single-acting”! This may only be done at the manufacturer’s plant. CAUTION Do not attach levers or tools to the drive’s spindle!
GAS 222.31 Ex2 6.2 Backwashing the Intake Filter (within the process stream) DANGER Adiabatic compression during gas blowback (explosion hazard)! Adiabatic compression may cause high gas temperatures and must be checked by the user. Gas blowback may result in high gas temperatures due to adiabatic compression. This can cause flammable gases to ignite spontaneously.
GAS 222.31 Ex2 6.3 Maintenance Schedule NOTICE When using the probe in explosive areas the maintenance schedule must be observed! Maintenance schedule for normal ambient conditions: Component Interval in operating Work to be performed To be performed by hours Entire probe every 8000 h –...
