NUNCA hagas vacío sin saber ESTO ⚠️ (Dañarás el compresor)

Performing a proper vacuum in refrigeration is the difference between equipment that lasts 10 years and one that fails in months. In this video, I explain why you should NEVER perform a vacuum without understanding this critical step that many technicians overlook. If you don't follow this procedure, you could irreversibly damage the compressor due to the presence of moisture or contamination in the system. What you will learn: Why vacuuming by time (30 minutes) is a technical error. How moisture affects compressor oil (polyolester vs. mineral oil).
