INTRODUCTION
The LD-3000 features a long life solid electrolyte sensor technology that
is designed to detect difficult HFC refrigerants such as R134a, R410A,
R404A, R407A, and R507, in addition to the new HFO R1234yf and
all HCFC (R22) and CFC (R12) refrigerants including SNAP approved
hydrocarbon blends.
The LD-3000 does not require rechargeable batteries.

OPERATING INSTRUCTIONS
1. TURN ON: Press the ON/OFF button once to turn on and again to turn off.
NOTE: Hold button down for approximately one second to turn unit off.
2. WARM UP CYCLE: The detector automatically starts heating the sensor. During the heating cycle, the
detector will sound a slow “beep”. Warm up time is usually less than 20 seconds.
3. READY MODE: The detector is ready to begin searching for leaks when the green sensitivity LED turns
on. The audible “beep” increases in frequency and the probe LED begins to blink steadily.
4. SEARCHING: When searching for leaks, move the sensor tip along A/C lines and fittings no further
away than .37 in (9.5 mm) and no faster than 3 in/sec (75 mm/sec). If the detector alarms, make smaller sweeps
back and forth until the leak source can be pinpointed.
NOTE: The LD-3000 only responds to changes in leak concentration. The alarm will reset automatically
if the sensor tip is held at the leak source. If the leak detector has been out of use for an extended period,
weeks or months, the following action is recommended:
• Power on the instrument and allow it to warm up and adjust to ready mode.
• Allow the leak detector to operate with the sensitivity level in the HI position for several minutes before
testing with the Leak Test Vial.This guarantees that sensor is fully conditioned for maximum response
to refrigerant gas.

Low Battery Indicator
Replace the four AA alkaline batteries when the red LED on the control panel is lit. Follow battery installation
instructions in MAINTENANCE section.
Audio Mute Function
To silence or mute the audio beep and alarm signal, press the MUTE button. To restore the audio sound, press
the MUTE button again.
NOTE: A few seconds are required to restore sound if the MUTE button is pressed in rapid succession.
Adjusting Sensitivity Levels
Leak detector will default to the NORM sensitivity level automatically once the unit comes out of the warm up
cycle and the green LED will turn on.
To change sensitivity levels, press the SENS button once for HI sensitivity (red LED will turn on) and again
for LO sensitivity (yellow LED will turn on).
Leak Test Vial
Leak detector comes with a Leak Test Vial that allows the user to make sure the detector is operating properly.
To test:
1. Remove the colored label dot in the center of the screw cap to expose the vent hole in the top of the cap.
(Figure B)
2. Turn on the leak detector and allow the instrument to complete the warm up cycle.
3. Place the sensor close to the small hole in the top of the Leak Test Vial. The beep rate should increase
indicating that the sensor and the electronics are working properly.

NOTE: Replace the Test Vial in the bag when not in use to extend shelf life. Replace Test Vial when the green
color is less than 1/4 full or at the time of the expiration date.

MAINTENANCE
Batteries
Install Batteries: Remove screw located at base end of unit and pull down hinged battery door. Insert four
AA batteries into the battery compartment as shown, noting Polarity Marks for battery orientation. (Figure C)
Figure C Handle Base Polarity Marks Battery Door Screw
Sensor
Replace Filter: Unscrew sensor tip as shown to replace filter. Replace filter whenever it becomes visibly dirty
or every 2 to 3 months depending on use.
Replace Sensor: Remove Sensor Cover by pulling out of Socket. Install the new sensor by aligning the Keyway
Notch in Sensor Cover with the Raised Keyway on Sensor Socket. (Figure D)
Note: Do not force Sensor Cover into Socket—misalignment will damage sensor pins.
Figure D
IMPORTANT: The instrument’s software is designed to alert the user if the sensor is dislodged or defective.
If the sensor is not fully inserted into the six-pin socket, or if it is defective, the instrument will not
come out of warm up cycle for proper operation when the power button is turned on. Additionally, if
the instrument becomes unstable during its operation, it is an indication that the sensor may be defective
or dislodged.
