1. Model ATD 36750 Refrigerant Gas Leak Detector Detects all CFC HFC HCFC HFO Refrigerants including blends User Manual C 4 Design certified by NN ASCI and Intertek to NAA meet SAE J2791 J2913 amp EN14624 INTRODUCTION The ATD 386750 features a patented 3 LED UV that emits the optimum wavelength for A C dye fluorescence The UV light can be used simultaneously with the heated sensor or independently The D440A UV does not require rechargeable batteries The ATD 36750 features a long life solid electrolyte semiconductor sensor technology that is designed to detect the more current and difficult HFC refrigerants such as R 134a R 410a R 407c R 507 and R 404c in addition to the new HFO 1234yf and all HCFC R 22 and CFC R 12 refrigerants including SNAP approved hydrocarbon blends The ATD 36750 s unique digital leak size indicator takes the guesswork out of whether or not to repair a small leak The digital display is independent from the audio alarm and sensitivity level allowing the precise pinpointing of the leak source FEATURES e Patented 3 LED UV lights e Long life stable sensor e Unique numeric leak size Indicator e R 134a sensitivity 05 oz yr R 22 sensitivity 025 oz yr e Designed Certified to meet Automatic calibration and SAE J2791 J2913 and reset to ambient EN14624 e Visual LED leak alarm near e 3 adjustable sensitivity levels sensor e Low battery indicator e True mechanical2. Remove the Plastic Seal Cap on the top of the Leak Test Vial by pulling it off see fig below Also remove and discard the circular Leak Test Cap Seal Turn on the leak detector and allow the unit to complete the warm up cycle Place the sensor close to the small hole in the top of the Leak Test 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 Remove the Plastic Seal _ Capto Test the Leak Detector lt Leak Test Cap Seal 4 Leak Test Vial NOTE Remember to replace the Plastic Seal Cap after the leak test is completed Replace the Leak Test Vial when the green media color is no longer visible and the leak media has evaporated Remove the threaded cap on the Vile to confirm the status of the leak test media After the leak test media has evaporated it is normal for there to be a green film on the wall of the Leak Test Vial 5 Maintenance Batteries Install Batteries Remove screw located at rear end of unit and pull down hinged battery door to open as shown Always insert all four batteries into the battery compartment in the same direction Note polarity mark on the inside of the battery door for proper battery orientation Polarity Mark Sensor Replace Filter Unscrew sensor tip as shown to replace filter Replace filter whenever it becomes visibly dirty or every 2 to 3 months de
