Page 7: Safety Instructions Part A
Safety Instructions Part A Safety Instructions Part A The device is only designed for situations of intended use. A non-intended use can lead to personal injury and property damage. Only use the device as intended. The device measures combustible or explosive gases and is installed in their environment. There is a potential risk of spread or ignition of a hazardous atmosphere. - Page 8 In the event of the error messages "potentially dangerous atmosphere" or "risk of explosion" as well as with loose hose ends, porous hoses or other leaks that lead to an explosion hazard, disconnect the device from the gas supply and shut it down. Contact Awite or an Awite contract partner.
- Page 9 Safety Instructions Part A The device contains fuses that are under electrical voltage. Danger to life by electric shock. Replace the fuses only in a non-energized state. Observe electrical safety regulations. Leakages in the AwiCONTAINER may create a hazardous atmosphere. The ventilation grilles are important in order to dilute the air in case of leakages.

Page 16: Ambient Conditions And Limits For Operation And Storage
Ambient Conditions and Limits for Operation and Storage Although the Awite gas analysis systems are designed for use under rough conditions, some requirements concerning the location and environmental conditions should be met in order to obtain a high accuracy of measurement and to avoid damaging the system. -
Page 17: Measuring Gas, Fresh Air And Exhaust Air Requirements
For AwiECO, the following applies: If there is a possibility of larger amounts of condensate in the measuring gas pipe and if the condensate traps cannot be checked on a regular basis, an additional gas cooler must be installed. -
Page 18: Zone Division
Product description 4.5.1 Zone division Inside the measuring gas pipes and inside the gas analysis system there are only very small amounts of gas, whose volume is far below hazardous amounts. Therefore no Ex-zone obtains in this case. Whether there is an Ex-zone around the gas analysis system or its pipes or not depends on the probability of the occurrence of an explosive gas mixture. -
Page 19: Release Of Potentially Toxic And Harmful Gases
Product description The pipes inside are considered to be technically leak-tight. Due to the way they are constructed, some sensors can only be used with plug connections which are secured with spring terminals. As an additional safety measure, the high-quality methane sensor that is integrated in the gas analysis system is used to track down possible leaks. -
