UEi RLD15B Refrigerant Leak Detector Instruction Manual
INTRODUCTION
The RLD15B features a solid electrolyte semiconductor sensor that is designed to detect the more current and difficult HFC refrigerants such as R134a, R1234yf, R410A, R404A, R407C, in addition to all HCFC (R22) and CFC (R12) refrigerants including SNAP approved hydrocarbon blends.
Getting Started
-
TURN ON:
Press Power Button -
WARM UP:
Allow 20 sec. to warm up (Indicator will blink and alarm will beep) -
READY:
When the flashing “8” stops and the green sensitivity indicator LED turns on -
The leak detector response to changes in refrigerant concentration. When detection occurs, move the probe away from the source and back again to confirm the leak source. The detector alarm will reset if the probe is held fixed at the source.
Leak Test Vial
The Leak detector comes with a Leak Test Vial that allows the user to make sure the detector is performing properly. To test: Turn the detector on and allow the unit to warm-up.
-
Remove Seal Cap
-
Place Sensor tip close to open vial.
-
The beep rate should increase and the Digital Leak Size Indicator should display a number from 4 – 6 indicating that the sensor and electronics are working properly.
-
Replace Seal Cap
NOTE: Always remember to replace plastic seal cap after leak test is completed. Replace Test Vial when the blue color is no longer visible.
Sensitivity Level
-
Press Sens.
-
button to Change / Scroll Sensitivity Levels.
-
(Indicated By LED)
Work light
- Press button to turn work light.
Battery replacement:
-
Remove battery cover on end of instrument. (Fig1)
-
Replace 4 (AA) batteries with correct polarity.
FEATURES
Leak Size Indicator
The digital leak size indicator remains off until a leak is detected. A number from 1 – 9 will be displayed for all HFC and HCFC refrigerants, regardless of the sensitivity settings.
The number will increase or decrease depending on the amount of refrigerant sensed. The maximum value will be displayed once the leak source has been located
Approximate Size Indications
| Maximum # Displayed | Leak Size (oz/yr) |
|---|---|
| 1-3 | < 0.1 |
| 4-6 | 0.1 – 0.5 |
| 7-9 | > 0.5 |
Audio Mute Function
- Press Mute button to Mute speaker.
Filter Replacement
- 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.
Sensor Replacement
-
Remove sensor by unscrewing sensor tip and pulling out the socket.
-
Install the new sensor by aligning the mark on the sensor cover with that on the probe and pressing together.
WARNING
DO NOT TWIST OR FORCE THE SENSOR INTO THE SOCKET. Misalignment can damage the sensor pins.

Cross Sensitivity to Automotive Chemicals
Some Automotive solvents and chemicals have similar hydrocarbon properties as R134a and may elicit a positive response (< 30 seconds) from the RLD15B. Before leak detecting, clean up any chemicals in the list below that elicit a response.
Rain-X® Windshield wash fluid
Ford® silicone lubricant
Ford® Gasket adhesive (when wet)
Ford® rust inhibitor (when wet)
Loctite® Natural Blue® Degreaser (undiluted)
Ford® brake parts cleaner (when wet)
Ford® silicone rubber (when uncured)
Motorcraft® antifreeze heated to 160˚F
Gunk® liquid wrench (when wet)
Ford® spot remover (when wet)
Ford® pumice lotion (with mineral solvent)
Ford® motorcraft brake fluid
Ford® carburetor cleaner (when wet)
