GETTING STARTED Installing Batteries 1. Remove the battery compartment door located on the bottom of the instrument, as shown below. Install batteries, Positive Polarity inwarels (towards the unit). (See figure 2). Fig. 2 OPERATING FEATURES Power Indication/Battery Test The ACL2500 provides two indications of battery voltage status; a Constant Power indicator (leftmost LED) and a Battery Test function. The Constant Power indicator allows the user to see the battery level at all times. The LE

OPERATING FEATURES • Battery Test Function. This feature is activated by pressing the Battery Test key. When pressed, the LED’s will display a three color bargraph indication of true battery voltage (See Fig. 4). The LED’s correspond to voltage as shown in the figure. Not all LEDs will always be on; the number of LEDs on, indicate the voltage level. 2.5V 2.6V 2.65V 2.7V 2.8V 2.9V 3.0V Red Orange Green Fig. 4 BATTERY TEST DISPLAY The battery voltage display will remain as long as the BATTERY TES

OPERATING FEATURES When the unit is switched on, it is set to sensitivity level 5. 1. To adjust the sensitivity, press the SENSITIVITYa or SENSITIVITYb key. When the key is pressed, the visual display will show the LED’s red. The number of LED’s lit, indicates the level (See Fig 5). Level one (lowest sensitivity) is shown by the leftmost LED. Counting from left, levels 2 through 7 are indicated by the corresponding number of red LED’s; i.e. level 7 is shown by all LED’s lit. 2. Pressing the SENS

OPERATING INSTRUCTIONS OPERATION: 1. Switch the unit on by pressing the ON/OFF key. The display will illuminate with the reset indication (Left LED green, all others Orange) for 2 seconds. 2. Verify the battery level by observing the constant power indicator (see above). 3. Upon turn on, the unit is set to sensitivity level 5. A rapid, but steady beep rate will be heard. If desired, the sensitivity can be adjusted by pressing the SENSI- TIVITYa or SENSITIVITYb key, as described above. 4. Begin

OPERATING TIPS 2. Take care not to contaminate the detector probe tip if the part being tested is contaminated. If the part is particularly dirty, or condensate (moisture) is present, it should be wiped off with a dry shop towel or blown off with shop air. No clean- ers or solvents should be used, since the detector may be sensitive to their ingredients. 3. Visually trace the entire refrigerant system, and look for signs of air conditioning lubricant leakage, damage, and corrosion on all lines,

OPERATING TIPS All Systems - 8. Following any service to the refrigerant system and any other service which dis- turbs the refrigerant system, a leak test of the repair and of the service ports of the refrigerant system should be done. APPLICATIONS The ACL2500 Leak Detector may also be used to: • Detect leaks in other systems and storage/recovery containers. It will respond to ALL halogenated (contains Chlorine or Fluorine) refrigerants. This includes, but is not limited to: CFCs e.g. R12,R11,R5

MAINTENANCE 3. If the tip itself is dirty it can be cleaned by immersing in a mild solvent, such as alcohol, for a few seconds, and then using compressed air and/or a shop towel to clean. NOTE: Never use solvents such as gasoline, turpentine, mineral spirits, etc... as these will leave a detectable residue and desensitize your unit. Sensing tip replacement: The tip will eventually wear out and require replace- ment. It is difficult to predict exactly when this will occur since tip longevity is
