Specification: Origin: Mainland China Item Type: Air-conditioning Installation Model Name: Fluorescent Oil Leak Detector Material Type: Fluorescent Dye + PAG Oil Product Size: 73.00x40.00x40.00mm/2.87x1.57x1.57inch How to use: 1. Use the same method as for the refrigeration oil, add the low pressure filler port, turn on the air conditioning switch (dual air box vehicles must turn on the air conditioning switch (front and rear). 2. The fluorescent leakage agent will form a circuit in each part of the refrigerant piping. 3. Run the air-conditioning system for 10 minutes. 4. Wear fluorescent protective eyewear and perform a detailed inspection using a small UV flashlight. If a fluorescent effect occurs, a leak exists and parts need to be repaired/replaced. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.
