LD3 OPERATORS MANUAL

PAG E 3

Introduction

The LD3 features a long life solid electrolyte semiconductor sensor technology that is designed to detect all CFC, HCFC, HFC, and HFO refrigerants including R-1234YF (HFO), R-134A (HFC), R-410A (HFC), R-22 (HCFC), R-407C (HFC), R-507 (HFC), R-12 (CFC), R-404C (HFC). The LD3 is designed to detect all SNAP approved refrigerant blends.

The LD3 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: For SAE J2913 sensitivity setting for R1234yf Mode hold down ON/OFF button until is the LED turns displays red.

2. Warm Up: The detector automatically starts heating the sensor. During the heating cycle the detector will sound a slow “beep” and the LED will alternate colors; green, red, yellow. The warm up cycle is complete when the audio beep increases in frequency and the LED turns to constant green (the default sensitivity level). Warm up is usually less than 20 seconds.

3. Search: Move the probe tip towards a suspected refrigerant leak at the rate of less than 2 inches (~50 mm) per second, no more than 1/4 inch (~5 mm) away from the suspected source.

4. Detection: If a leak exists, the sound will increase in rate and pitch.

NOTE: The leak detector responds to changes in refrigerant concentration. When detection occurs, move the probe away from the source and back

again to conrm the leak source. The detector alarm will reset if the probe is held xed at the source (see Automatic Calibration Feature).

PAG E 5

Adjusting Sensitivity Levels

In addition to the automatic calibration, the audio alarm trigger level can be set by the user to 3 different sensitivity levels- LO (Yellow), MED (Green), HI (Red). If the detector is continuously alerting while pulled away from the suspected area of the leak, the sensitivity level can be adjusted so the detector will only alert when the sensor is close to the source of the leak.

The Leak Detector will default to the MED (Green) sensitivity level automatically once the unit comes out of the warm up cycle. To change sensitivity levels when the detector is on, press and hold the ON/OFF button down for several seconds. The indicator LED at the top of the keypad will scroll changing colors; Green for MED, Red for HI and Yellow for LO. Release the button when the desired sensitivity level is displayed.

Leak Test Vial

The leak detector comes with a Leak Test Vial that allows the user to verify the detector is performing properly. Check the expiration date on the vial before testing the leak detector.

To test:

1. Remove the colored label dot on the center of the screw cap to expose

the vent hole. (see g. below)

2. Turn on the detector and allow the unit to complete the warm up cycle.

Set sensitivity level to HIGH.

3. Place the sensor close to the hole in the Leak Test Vial. The beep rate

should increase indicating that the sensor and electronics are working properly.

NOTE: The leak detector responds to changes in refrigerant concentration. When detection occurs, move the probe away from the source and

back again to conrm the leak source. The detector alarm will reset if the probe is held xed at the source (see Automatic Calibration Feature).

Remove label dot over vent hole before testing.

MAINTENANCE

Batteries

Install Batteries: Unscrew the battery cover located at the base of the

unit as shown. Insert all four batteries into the battery compartment in the same direction. Note the polarity mark on the inside of the battery compartment for proper battery orientation. Re-

place batteries when the LED Indicator display ashes RED.

Sensor & Sensor Filter

Replace Filter: Unscrew sensor tip as shown to replace lter.

Replace lter when it becomes visible dirty or after 30 hours of usage.

Replace Sensor: Remove sensor by pulling it out of the socket. Install the new sensor by aligning the Keyway notch in the sensor cover with

the raised keyway on the sensor socket holder (see gure below).

Note: Do not force sensor into socket. Misalignment can damage the sensor pins.

Push straight on (do not twist) TO INSTALL sensor.

Unscrew tip to

replace lter.

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 the “Warm Up” mode 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.

Note: 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 come out of warm up, and then run it with the sensitivity level in the (Hi) high position for several minutes before testing it with the Leak Test Vial. This action will guarantee that the sensor is fully conditioned for maximum response to refrigerant gas.
