LD5 OPERATORS MANUAL
PAG E 3
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 conrm 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
.
5 White LED
Inspection Lights
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.
