How to determine the place to install Gas Detectors

Installation & Usage:

1. At first, confirm the proportion between the air and the flammable gas, then fix up the alarming at the suitable position which is within 1.5M distance to the semidiameter of air headstream:

A. Gas is lighter than the air and float in the higher position.

B. Natural gas is lighter than the air and float in the higher position.

C. Liquid oil gas is heavier than air and sedimentate in the lower position.

2. After put through the power, the alarm "tick" one, at the same time the power lamp light and the function lamp is green and flash. After about 2 minutes the green lamp crush out which indicate it is watching. When it induces the gas leakage, it will make "Di, Di" alarming, meanwhile the function flash with red ligh. It will in normal status when the warn is eliminated.

3. If the sensor has any trouble, the annunciator will give out "Di" and the indication light will be yello and lighting long time. After the malfunction is eliminated it will in normal status.

6. Not installed it to the position that slather the fixature, pesticide or oil paint adhesive alcohol thinner and ect to prevent to affect the function of sensor organ.

7. If there have some trouble, please don't knock down and repair the alarm by yourself, please notive the supplier to repair it.
