    Refrigerant Leak Detector with Pump. Please read this user’s manual carefully and thoroughly before using the product. The RLD400’s long-lasting solid electrolyte semiconductor sensor can detect leaks of all halogenated (chlorine or fluorine-based) refrigerant gases currently in common use. They include HFCs (hydrofluorocarbons), CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons).

  • Page 3: How It Works

    4 ft. onto concrete. HOW IT WORKS A small mechanical pump inside the RLD400 draws a sample of air through the tip of the instrument’s 17-in. long probe into a proprietary sensor 1-1/2 inches downstream. A proportional halogen detector in the sensor determines whether any refrigerant gas is in the sample.

  • Page 4: Key Features

    A third feature of the RLD400 that helps locate leaks is a red LED adjacent to the sensor at the end of the probe. This light flashes in sync with the beep. In other words, it flashes three times every two seconds whenever the unit is on, and much faster whenever the unit detects refrigerant.

  • Page 5: What's In The Case

    Mute button. The warmup cycle normally takes 17–20 seconds. 3) READY. The RLD400 is ready to search for leaks when: 1) the display stops flashing “0” and goes dark; 2) the green LED indicating NORM sensitivity (the default level)

  • Page 6: Checking For Leaks

    LED CHECKING FOR LEAKS Position the end of the RLD400’s flexible-obedient probe—which retains its configured shape—close to any suspected source of leaking refrigerant gas. In a vehicle, wet oily areas around hose connections and fittings, and greasy streaks radiating outward around the compressor clutch or on the underside of the hood just above the compressor are telltale signs of a leak.
  • Page 7 The reading reflects the concentration of refrigerant gas sensed. The maximum value will be displayed when the tip of the probe is at the source of the leak. Try switching between different sensitivity levels while moving the probe until the highest number appears.

  • Page 8: Using The Leak Test Vial

    NOTE: If the above check does not produce a non-zero reading, either your leak test vial is empty or your RLD400 is defective. If the bottom of your leak test vial does not appear green, replace the vial. To locate a replacement, search the Internet for “Refrigerant leak detector reference”.

  • Page 9: Specifications

    “AA” batteries. To do so, follow the procedure in the Setup Instructions section of this manual. CHANGING THE FILTER The RLD400 ships with a pack of five small disc filters that install upstream of the sensor. Replace the filter whenever it becomes visibly dirty, or every few months, depending on use.
