OPERATION
• ALERT: If the sensor is faulty, the display will pop up: "Error: Sensor"
• WARM-UP COUNTDOWN: Please wait for about 30 seconds until the warm-up finishes
WARNING!
• Please keep moving the device during detection. This unit is designed to detect the relative concentration of gases,
that if the detected concentration remains unchanged in the stationary environment, it will not be able to pinpoint the
leak.
• Please ensure the system pressure is at least above 340 Kpa (50 psi) before detection as many refrigerant leaks can't
be detected at low pressure.
• Do not place the detector close to organic solvents, detergents or high voltage power supplies. Please wipe up the
detectors with a clean towel.
• Before starting, please confirm the battery is sufficiently charged (it normally takes about 30 minutes for one detec-
tion).
1. Press
to turn on the detector. Wait for the warm-up countdown in order to reach the optimal detection status. It
takes about 30 seconds before it enters the main interface.
2. Press SENS button to adjust to your preferred sensitivity level (default level is high).
3. Locate the places that are most likely to have refrigerant leaks, such as: joints in refrigerant lines, points that have
changes in cross section, points that have changes in vertical section.
Visually trace the entire refrigerant system for all lines, hoses, fittings, couplings, service valves, etc. for signs of
lubricant leak, damage and corrosion as the likely leak points.
4. Move the probe slowly (about 3 ft/s or 75 mm/s) at these suspicious places, move back and forth but no more
than 0.25"/6m m away from the leak areas.
NOTE: A closer probe position and slower "sweeping" movement usually improve the possibility of finding a
leak.
5. The alarm and LCD display will indicate the detected leak at the same time:
ALARM: The sound will increase in proportion to the leak intensity. The faster the alarm beeps, the higher the leak that
has been detected.
LCD DISPLAY: The graph will increase from bottom to top in proportion to leak intensity. The higher the bar graph rises,
the higher the leak that has been detected.
BATTERY & FILTER
BATTERY CHARGING & MAINTENANCE
WARNING!
• Avoid complete charging and discharging frequently, otherwise it may affect battery life.
• Do not dissemble the built-in rechargeable lithium battery.
• If the detector will not be used for a long time, please charge it before hand to prevent battery life reducing due to
self-discharging. Not recommended to store for more than 6 months.
1. Use DC 5V/1A power adapter to charge the detector
Charging indicator in red: the battery is charging now;
Charging indicator in blue: the battery is fully charged.
FILTER REPLACEMENT
The filter can block large particle contaminants and moisture to reduce false alarms caused by excessive humid-
ity. Please replace the filter when it is seriously polluted (black and clogged).
Follow the steps below:
1. Unscrew the protection cover counter-clockwise
and remove the contaminated filter (do not pull
out the rubber holder, or it may cause open the
circuit of the air tube).
2. Place a new filter and screw the protection
cover clockwise.

California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
