ALD-100 ELECTRONIC
REFRIGERANT LEAK DETECTOR

WARNING Read this manual before using this product.
Failure to do so can result in serious injury.

Main Features

• Detect leaks in all A/C refrigerant systems. Respond to all halogenated refrigerants.
• 7 levels of sensitives
• 18 alarm levels (Single color visual and audible)
• Battery test function with voltage indication
• Fast and easy reset function

Setup

1. Turn on the device by pressing the ON button. The display will show the indication for 3 seconds.
2. The first light flashes green to prove that the battery is good.
3. Press the arrow up or down button to change the sensitivity. The default level of sensitivity is 5.
4. A continuous beep tone will indicate the unit is normally functioning.
5. Start searching the leaks. When a leak is located, the beep tone will change to a siren tone. Also, you will see the LED display the alarm. (See page 3)
6. During the use, the sensitivity can be adjusted at any time by pressing the arrow key.
7. If a full alarm is indicated before you have found the source of the leak, you can reset the detector to zero by pressing the reset key. This will allow you to find progressively greater concentrations, and eventually find the source of the leak.

Tips

1. Adjust the sensitivity up only when a leak can be found. Adjust the sensitivity down only when resetting the unit does not allow you to locate the leak.
2. In areas contaminated with leaked gas, reset the unit to zero it out and allow you to find heavier concentrations of gas. DO not move the probe while the unit is being reset.
3. In windy areas, it may be difficult to find even a large leak. Shield potential leak sites from wind to make finding concentrations of leaked gas easier.
4. The detector may alarm if the probe tip comes in contact with moisture or solvents.Do not allow the tip to contact these materials.

Sensitivity Indications

Seven levels of sensitivity, which increase 64 times from level 1 to level 7 allow you to focus on the concentration appropriate to your location.

Alarm Indications

The Electronic Refrigerant Leak Detector features 18 alarm levels from low to high to help you find the leak.
The alarm level will increase as the leak is being approached. Alarm levels are indicated by the last 6 LED’s lighting and changing in color from Red, Green and Orange. The LED’s will light and change color from left to right, one at a time. See alarm level chart below.

Battery Level Indicator

Green: good.
Orange: low.
Red: need to replace the battery.

Reset Function/ Automatic Circuit

1. Reset
   Press RESET key to reset the unit to zero.
   LED will turn red for 2 seconds, this confirms the reset action completed.

2. Automatic Circuit.
   When the unit is first powered on, it will set itself to ignore the current level of halogen in the atmosphere. This allows the unit to identify leaks by the higher concentration of halogen present at the leak location.
