1. Introduction
Thank you for purchasing a New Cosmos Gas Leak Detector. Please read this Instruction
Manual thoroughly before using the Gas Leak Detector to help prevent gas leakage
accidents and to aid in safety inspections.
XP-702III-A(S) and XP-702III-F(S) Gas Leak Detector detect leakage of any two gases of
town gas, LPG, and Freon (switchable)*. XP-702III-B(S) Gas Leak Detector detects leakage
of one gas*. When the gas concentration exceeds the set value, a buzzer and lamp provide
notification of the gas leakage to help prevent gas leak accidents.
*Check the target gas with gas name label on the Gas Leak Detector.
Read and understand thoroughly this Instruction Manual regardless of your experience with
using Gas Leak Detectors.
Do not use this Gas Leak Detector for improper purpose. Do not use this Gas Leak
Detector in undocumented way in this manual.
Symbols
The following symbols are used for safety purposes:
Indicates an imminently hazardous situation, which will result in death
or serious injury if not avoided.
Indicates a potentially hazardous situation, which will result in death
or serious injury if not avoided.
Indicates a potentially hazardous situation, which may result in minor
injury or property damage if not avoided.

Safe Operation
Be sure to observe the following to use the product safely and properly.
Be sure to turn ON the power in clean air. Since zero adjustment is
performed automatically, the proper gas concentration will not be
displayed when turning on the power in gas atmosphere.
Do not block the inlet and outlet. Otherwise, it may no be able to detect
properly
Do not allow water or liquids to enter the Gas Leak Detector. It may
cause interference to the gas detection and may damage the Gas Leak
Detector.
Make sure that Filter Element is clean. If the Filter Element is dirty or
wet, it may no be able to detect properly.
Do not block the buzzer hole. It will muffle the alarm.
WARNING
Remove the batteries if the Gas Leak Detector will not be used for an
extended period of time.
Check the remaining battery charge periodically (approximately once a
month) even if the Gas Leak Detector remains unused for an extended
period of time. Replace batteries if the batteries are leaking when the
remaining battery charge is low.
Do not attempt to disassemble, modify or alter the structure or electric
circuits of the Gas Leak Detector. It may affect its performance.
Do not leave the Gas Leak Detector in hot and humid environment for
a long period of time. It may affect its performance.
Do not use the Gas Leak Detector in places where the temperature or
humidity fluctuates greatly. It may affect its performance.
Keep the Gas Leak Detector away from significant changes in
atmospheric pressure. It may affect the performance of or damage the
sensor.
Avoid high mechanical impacts, dropping and throwing the Gas Leak
Detector. It may affect its performance.
In case of dew condensation, conduct an inspection after drying the
Gas Leak Detector completely before use.
Do not use the Gas Leak Detector near silicon sealing agents or in
atmosphere containing silicon gas. It may affect its performance.
Make sure to use the specified batteries. It may affect its performance.
The Gas Leak Detector may detect gas or solvent vapors other than
the target gas. Consider the inspection environment when using the
Gas Leak Detector.
Detecting high concentration of SO2or Cl2may decrease the sensor
life or increase errors.
CAUTION
If the gas alarm is activated, take all necessary precautions immediately
to prevent explosion.
High concentration of combustible gas may exhaust from the gas
outlet. Keep the gas outlet away from the fire.
This product is not explosion-proof and thus should not be
used in a hazardous area.

3. Operating Procedure
Operating Procedure
1. Insert the batteries
There are no batteries in the Gas Leak Detector at the point of purchase. Insert the
enclosed batteries into the Gas Leak Detector. (Refer to Battery Replacement on
page 18.)
2. Turn ON the power, Warm up, Displays gas sensitivity
1) Press the power button for approximately one second. The buzzer beeps and the
power will be ON.
2) “ADJ” is displayed on the LCD while the Gas Leak Detector is warming up. The
stability of sensor is indicated with five gas sensitivity lamps (green). As the
sensor stabilizes, the flashing lamp moves down in order from the lowest
sensitivity level (3). Before warm-up is completed, the highest sensitivity level (0)
lamp will flash. (The maximum warm-up is three minutes.)
Always perform the daily check before using the Gas Leak Detector.
(Refer to page 19.)

WARNING
If the sensor stabilizes quickly, all of the lamps may not flash one at a
time. If the Gas Leak Detector remains unused for an extended period of
time, the warm-up time may increase and “E-S”may be displayed on the
LCD. (Refer to Sensor Error on page 15.) If sensor error is displayed,

Check the target gas before detection.
For a model of one-gas type (XP-702III-B(S)), check the gas
name with gas name label on the Gas Leak Detector. For a
model of two-gas type (XP-702III-A(S) or XP-702III-F(S)), either
“GAS1” or “GAS2” is displayed on the LCD. Check the name of
the corresponding gas with gas name label on the Gas Leak
Detector.
The target gas is displayed on the LCD by pressing the restart
pump button. (Refer to Displaying the Target Gas Name on page
