Introduction

The LD5 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 LD5 is designed to detect all SNAP approved refrigerant blends.

The LD5’s unique graphic color LCD display and sweep mode function conveys messages, graphics and prompts giving the A/C technician real-time information to help locate the source of the leak and ensure the leak detector is always at optimal performance. The LED inspection

light aids the technician to locate and inspect all A/C suspect ttings and

components while searching.

The LD5 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 hold down ON/OFF button until R1234yf Mode is displayed.

2. Warm Up: The detector automatically starts heating the sensor. During the heating cycle, the LCD display will display the message

“WARM UP” with a progress bar (see gure). Warm up is usually

less than 20 seconds.

3. Search: The display will show “SEARCH” and the audio “beep” will begin to sound. 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 frequency, and the display will show the bar graph indication of the leak size.

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).

Inspection Light Operation

1. Turn on the white LED light by pressing the LED button once. (See control panel on page 4).

2. Holding the leak detector approximately 10” to 14” away, shine the LED light beam slowly over the components, hoses, and metal lines that make up the A/C system.

3. I

nspect all A/C ttings, hoses and components for excessive wear

or damage

Auto Shut-off

The LED Inspection Lights will automatically shut off after 5 minutes. This will ensure proper battery life in case the LED lights are left on inadvertently.

LD5 OPERATORS MANUAL

Leak Size Indicator

The LCD bar-graph leak size indicator remains off normally but once a leak is detected, a number of bars will be displayed. The number will continue to increase or decrease depending on the amount of refrigerant sensed. The display will be the same for all HFC and HCFC refrigerants regardless of the sensitivity setting.

The maximum value will be displayed once the leak source has been located. The table below can be used to approximate the size of leak:

Maximum No. Bars Displayed Leak Size (oz/yr)

1-4 (green color) < 0.1 5-6 (yellow color) 0.1 to 0.5 7-10 (red color) > 0.5

LD5 OPERATORS MANUAL

PAG E 7

Automatic and Manual Calibration

To allow the user to nd the leak source easily, the detector will calibrate

itself either automatically (default) or manually to the ambient and reset the alarm as soon as there is detection

In Automatic mode the detector will automatically reset the alarm. In Manual mode, the detector will continue to alarm if gas is detected until the user presses the SENS button to reset the alarm. Both modes allow the user to get closer to the leak source without the detector continually alarming. In Automatic mode, once the source of the leak is found, the detector will not alarm again until the probe is moved away from the source and back again. In Manual mode, once the source of the leak is found, the detector will continue to alarm at the source until the SENS button is pressed.

To use the detector in Manual Calibration mode: Press and hold the SENS Selector and release when the AUTO icon is replaced by MAN on the display. To return to Automatic Calibration, press and hold the SENS button and do not release until the AUTO icon is displayed.

Note: the sensitivity levels can only be changed in Automatic Calibration mode. To change sensitivity levels while in Manual mode, return to Automatic mode, select the desired level and return back to Manual mode.

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, MED, HI). 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 sensitivity level automatically once the unit comes out of the warm up cycle. To change sensitivity levels, press the SENS once for HI sensitivity and again for LO sensitivity.

LD5 OPERATORS MANUAL

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 the Leak Test Vial. The beep rate should increase and the Leak Size Indicator should display 3-6 bars 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 direction noting the polarity mark on the inside of the battery compartment for proper battery orientation as shown. Replace batteries when the display shows the message

REPLACE BATTERIES.

Sensor & Sensor Filter

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

place lter when it becomes visible dirty or when the display shows

“REPLACE SENSOR FILTER.” The LD5 will keep track of the number of hours of usage and alert the user when it is time to replace it.

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.

Keyway Alignment

Pull straight out (do not twist) TO REMOVE sensor.

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. In this case, the message screen as shown on the right will be displayed. 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.
