1. The installation shall be carried out in accordance with GB/T 3836.15-2017 Explosive Atmospheres - Part 15: Design, Selection and Installation of Electrical Installations. The installation of meters shall be carried out by professionals of the gas company for initial installation and commissioning.
2. This product has undergone explosion-proof treatment and shall not be changed at will.
3. The product shall not be collided or severely impacted during transportation, and shall be protected from rain and sand.
4. This product should be stored in a ventilated and dry place.
5. It is prohibited to detect leakage in case of open fire. When piloting fire, the air in the gas meter must be exhausted to prevent accidents.
6. When installing the battery, note that the side with the spring is the negative pole of the battery. The battery shall be replaced under the condition of good ventilation and no gas leakage.
7. Electrostatic hazard, so must be wiped with wrung wet cloth.
1. It is not allowed to replace components or structures that affect the explosion-proof performance at will, so as not to affect the explosion-proof performance.
2. Warning sign: Potential electrostatic charge is dangerous. During the normal use, maintenance and cleaning of gas meters, we should avoid the ignition hazard caused by electrostatic charges. Do not touch and wipe the equipment when it is used in explosive environment. If it is necessary to wipe and touch, it should be carried out in a well-ventilated, no gas leakage place. Wipe the shell with a wrung wet cloth. And it is strictly forbidden to wipe the shell with a dry cloth!
3.3. The battery must be replaced with the same type of battery under the condition of good ventilation and no gas leakage.
