The car air conditioning system adopts standardized automotive grade design, modular layout, stable performance, fast cooling, energy-saving and low-noise 360 degree wide-angle air supply, intelligent variable frequency high-efficiency cooling, providing you with a comfortable driving environment. The metal+ABS shell makes it sturdy and durable, and the fully waterproof seven blade high-efficiency electronic fan has better heat dissipation effect. Installation matters. 1. Wiring: Take out 2 positive and negative power cords. Red is the positive electrode, black is the negative electrode; Connect the positive and negative terminals on the upper part of the outdoor unit. Pay attention to the positive and negative poles; The positive and negative poles must be connected to the battery, and must not be reversed. Finally, fix and wrap the circuit. Require neat and beautiful appearance, firm and reliable. 2. Fill R134A (did not add before shipping): The high and low pressure connecting pipes must be connected to an external pressure gauge and evacuated for more than 15 minutes using a rotary vane vacuum pump. The pressure indicated by the low pressure gauge is less than -0.1MPa. After completion, wait for a period of time to observe if there is any air leakage. Take out 3 cans of R134A, connect the pressure gauge, invert and turn on the pressure, observe the switch, it can fill up to 800 grams; Observe whether the pressure is normal. The normal pressure of the low-pressure gauge is 0.3-0.5MPa, and the normal value of the high-pressure gauge is 1.3-1.5MPa. 3. Which step went wrong during the installation process. There is a flashing indicator light on the panel. You can confirm the fault based on the panel fault diagram above. For example, insufficient voltage, insufficient or excessive R134A. 4. If you have any questions, feel free to consult us at any time. 1. Split design: This 12 volt split type car air conditioner is lightweight, easy to install, and easy to maintain.
