1. 3 Most refrigerants deplete the ozone layer that blocks the Sun s harmful ultraviolet radiation In the U S the Clean Air Act of 1990 and later amendments require owners or operators of refrigeration and air conditioning equipment with refrigerant charges greater than 50 pounds to repair leaks within 30 days when those leaks result in the loss of more than 15 comfort cooling or 35 commercial cooling of the charge over a 12 month period The RLD400 s proprietary sensor and detection technology are the keys to its excellent performance and durability Compared to products of decades past with heated sensors the RLD400 warms its sensor to a much lower temperature The reduction in heat reduces the instrument s power consumption and improves sensor stability while extending the life of the sensor and maintaining its electrochemical function Test data indicate no decline in the sensor s performance after thousands of hours of operation Sensor life is specified at more than ten years of normal use In addition because the instrument and sensor comply with SAE Standards J2791 and J2913 and the European Standard EN14624 the sensor will not be damaged by overexposure to refrigerant gas or by contamination by water To comply with SAE J2791 the RLD400 also had to demonstrate its sensitivity to 15 different chemicals and pass two garage durability tests one requiring it to survive three drops from 4 ft onto concrete HO2. If the startup sequence fails to complete after 60 seconds abort the process by powering off the unit Then check the integrity of the connection between the sensor and the probe by doing the following 1 Pull the black probe tip assembly straight out and away from the sensor socket without twisting it This disconnects the sensor 2 Line up the keyway notch on the probe tip assembly with the raised keyway on the sensor socket holder 3 Carefully push the sensor back into the socket without forcing or twisting it misalignment can damage the sensor s pins This reconnects the sensor Push straight on do not Unscrew tip to Fiter twist to install sensor _ Keyway alignment replace filter i Sensor socket and red refrigerant Pull straight out do not detected LED twist to remove sensor 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 Another place to check sooner rather than later is the evaporator located inside the heater defroster plenum under the dash Whenever the sensor at the end of the probe senses a refrigerant gas that it has been designed to detect 1 The red LED at th
3. 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 When the red LED begins to flash rapidly your eye will naturally be drawn to it and therefore the location of the leak Like the leak size readout the LED at the end of the probe is bright enough to be visible in full sunlight The RLD400 automatically compensates for ambient levels of refrigerant gas No manual sensitivity adjustments or power adjustments are required The instrument is supplied with a proprietary leak test vial that lets you verify that it is working properly prior to searching for a leak The RLD400 is powered by four AA batteries which are included in the case KEY FEATURES e Proprietary sensor with lifetime of thousands of hours of operation ten years of normal use e Detects all commercially available HFC HFO HC HCFC and CFC refrigerants as well as blends and newly approved replacements such as R 22 and R 1234yf e Triple redundant leak indication loud fast beep bright flashing LED digital leak size reading e True mechanical pump draws in samples increasing sensitivity e Sensitivity of 0 05 oz year 1 4 g year to R 134a e Three sensitivity levels e Fast warmup e Comfortable neoprene grip e Automatic calibration a

7. W 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 If any gas is detected the sensor and other circuits measure the amount of refrigerant and convert the value to an electrical signal If no leak is detected no signal is produced and the display remains off dark When a leak is detected the signal is amplified digitized and displayed on the front panel as a large bright red number from 1 to 9 corresponding to the size of the leak 1 for the smallest leaks 9 for the largest The digital readout makes it easy to pinpoint the source of a leak and helps you decide whether it is large enough to be worth plugging The reading is independent of the selected sensitivity level three are available and is at its highest when the tip of the probe is at the source of the leak A table in the Operating Instructions section of this manual correlates display readings with leak size in ounces per year The RLD400 simultaneously uses sound to help locate the source of a leak Whenever the unit is on it continuously produces three very loud beeps every two seconds When a leak is detected the frequency of the beeping increases dramatically The beeper can be muted by pressing a dedicated button on the front panel A third
