1. Installation Instructions: The power supply voltage for the detector must not be less than 18V. Choose the appropriate power cable based on the installation distance. The signal cable should not run parallel to high-voltage power lines at close proximity.

2. Installation Location: Detectors are installed in areas where the monitored gas is prone to leakage, and the installation position is determined based on the relative air density of the gas being measured. When the density of the gas being measured is greater than air, the detector should be installed 30-60 cm above the ground, with the sensor facing downward. When the density of the gas being measured is less than air, the detector should be installed at a height of 0.5m to 2m above the release source or 30-60 cm above the ceiling, with the sensor facing downward. To ensure proper use of the detector and prevent malfunctions, please do not install it in the following locations: a) Directly affected by steam or smoke; b) Areas with high air flow, such as gas outlets, ventilation fans, and doors; c) Areas with excessive moisture or water droplets; d) Temperatures below -20℃ or above 50℃; e) Locations with strong electromagnetic fields.

3. Installation Method: Unscrew the weather shield on the outer side of the sensor, fit the mounting bracket, secure it with M4x5 screws. Depending on the detector's installation location, fix the bracket to the wall or other support with two M6 expansion bolts. The detector must be installed securely and reliably grounded.
