WARNING!!

• Wear Safety Glasses / Wear Gloves
  Please protect your eyes and skin while using the UV LED accessory during detection. Never look directly at the UV ray.

• Please install clean filter before detection, otherwise it may damage the sensor

• Please charge the detector promptly to ensure sufficient battery level

• Do not touch or detect any charged objects using the probe

• Do not let water enter the air inlet of the probe

• Please avoid breathing the refrigerant vapors. Inhalation of high concentrations of refrigerant is harmful and may cause unconsciousness or death.

• The detector has a built-in rechargeable lithium battery, please do not change to other battery types

BUTTONS & DISPLAY

BUTTONS

• : Press and hold for 2 seconds to turn on the detector; press again to turn it off
• SENS: Press to select preferred sensitivity level (low, medium and high)
• MUTE: Press to turn on/off the buzzer
• RESET: When in the presence of a high concentration of gas and the unit is acting erratic, remove the detector from this environment for 60 seconds and press the reset button to re-engage.
• PEAK: Press and release to mark or unmark the maximum leak. If unmarked, the peak value will be cleared

DISPLAY

1. ALARM: Indicates alarm status. red icon: disabled; green icon: enabled

2. PEAK VALUE: Indicates the maximum detected leak
   Note: PEAK function must be on or it will not show peak value

3. LEAK VALUE: Indicates the current detected leak. The higher the leak concentration, the higher the bars

4. SENSITIVITY LEVEL: Displays current sensitivity level. 3 levels are available for different needs. H : high sensitivity; M: medium sensitivity; L: low sensitivity

5. BATTERY LEVEL: Displays current battery level Green: full battery; Yellow: low battery; Red: extreme-low battery, please charge as soon as possible

6. PEAK ON/OFF: Indicates peak function status. The display shows on or off to indicate the peak function is enabled or disabled (turning off peak will clear all recorded peak values).

7. Charging and status indicator

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 detection).

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 humidity. 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.

WARNING: This product can expose you to chemicals including Di (2-ethylhexyl) phthalate, lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
