Packaging, storage, directions for use

1, solid gas meter should be loaded in the box, do not allow the gas meter in the free running in the cabinet, handle with care when handling.
2, gas meter should be stored in rain moisture, not affected by mechanical vibration or shock, temperature range - 10 ~ + 40, environment relative humidity of 80% or less.
3, gas meter installation should be appearance inspection, check the gas meter for damage in transit.
4, before installation should be sealed performance check, enter 1.5 times the maximum working pressure of compressed air, close the export checking for leakage phenomenon.It is forbidden to open fire.
5, gas meter shall be installed level, no tilt, inversion, does not apply to strong vibration, installation time is consistent with the direction of the gas and air flow direction.
6, without the consent of the department of management, the user may not arbitrarily disassembling or unsealed debugging, to ensure the accuracy of gas meter and the safety of the user.
