Nitrógeno y Bomba de Vacío PASO A PASO

In this video, I demonstrate step-by-step the correct use of nitrogen and a vacuum pump in air conditioning systems. I explain how to perform a nitrogen leak test, how to properly connect the manifold gauge, and the correct vacuum procedure to ensure proper system dehydration before startup. I also cover common errors, the correct sequence of procedures, valve opening, and the initial power-up of the equipment, including inverter units, applying sound technical judgment and best professional practices. 📲 Technical inquiries and training: https://wa.me/595982244476 🌐 Official website: https://refrigeracionalonso.com ⏱️ VIDEO CHAPTERS 0:00 Starting the sealing and dehydration process 1:03 How to connect the pressure gauge 1:19 How to use nitrogen in refrigeration 3:53 How to release nitrogen 4:35 How to use the vacuum pump 7:12 How to open refrigerant valves 8:20 Initial start-up of the mini-split 9:01 Starting the inverter compressor 10:23 Disconnecting the pressure gauge or manifold 11:28 Final steps
