Why do we need gas leak detectors?
Gas leak detectors are mainly used to detect the concentration of flammable or toxic gases in the air and provide early warnings of potential dangers. In daily family life, using gas leak detectors can prevent fires and explosions, prevent poisoning, and effectively avoid accidents. In industrial production, gas leaks may cause equipment damage or production stoppages. Detectors can monitor the airtightness of pipelines or equipment in real time, identify problems promptly, and take measures to reduce maintenance costs and property losses. In industries such as chemical engineering and pharmaceuticals, gas leaks may pollute the environment. Detectors can monitor the emissions of pollutants such as carbon dioxide and sulfur dioxide to ensure compliance with environmental protection standards.

How To Operate?

1. Open battery cover and insert two(2) AA batteries (with(+) side pointed towaras tip). The wand shortly sounds two times in case battery correctly installed.

2. Remove the red protective cap before turning on unit. Cap must be off for sensor to work properly.

3. Press and hold the white power button for two seconds to start a 25 second self-inspection, 4 LEDs light will blink in sequence. The detector is ready for use after beep sounds and LED(Yellow, Orange, Red) lights turn off and LED(Green/Red) lights on in green color.

4. Place the sensor tip of the wand along the connection point that you are testing. Be sure cap is off. If checking tor leaks on a gas pipe, be sure to move the sensor slowly along the pipe over joints&fittings. Caution must be taken when utilizing the wand outdoors or in the presence of winds or air flow. Wind direction, strength, leak size and dilution o1 detectable gases may interfere with proper readings or mask a potentially dangerous gas leak.

5. IF GAS IS DETECTED, an audible alarm will accompany a yellow, orange or red light: (LED Yellow, Orange, Red )
GREEN lightilluminates-the detector is powered on and Air is safe
YELLOW light illuminates and buzzer beeps -Small amount of gas detected
ORANGE lightilluminates and buzzer beeps - Medium amount of gas detected
RED light illuminates and buzzer beeps-Significant amount of gas detected

WARNING!If red indicators light up, ventilate the area IMMEDIATELY and move to a safe location away from the residence. Then call your local gas utility company for assistance. After leak is repaired, repeat steps 2 through 4.

6.SENSOR FAILURE In case LED(Green/Red) turns to red color with continuous buzzer and LED(Yellow, Orange, Red )are all off during use, the sensor of detector fails is no longer working properly.
Stop using and replace the detector immediately.

7. After use, be sure to turn off the device before storing. To turn off, press the power button once, green light will shut off. Unit will automatically turn off after 5 minutes since powered on. Replace protective cap to help protect sensor and reduce risk of contamination.

8. Be careful not to drop unit or push down on tip. This could damage the sensor.

9. DO NOT dip or submerge detector in liquid. Replace detector if it comes into contact with liquid.

10. DO NOT disassemble detector. Internal contents contain chemicals known to the State of California to cause birth defects or reproductive harm. Replace detector if it has been disassembled.

11. DO NOT use wand in environment with relative humidity above 95%.

12. DO NOT use wand in temperatures less than 15°F or in temperatures greater than 110°F.

COMBUSTIBLE GAS LEAK DETECTOR

Note: At a minimum, replace batteries once a year for optimal performance. (Battery life is limited to approximately 1,000 minutes of usage.) The unit is not working if LED(Green/Red) does not light on in green color.

WARNING! Turn the unit on in a well-ventilated area. Fresh air is needed to generate an accurate "clean" reading. The unit will not operate properly until a "clean" reading has been made.

DANGER! Fuel gases are odorized(rotten egg smell) so that their presence can be detected. If you detect a presence of gas by scent, do not use this device to confirm. Ventilate area immediately and move to a safe location away from the residence. Then call your local gas utility company for assistance.
