From pre-installation to final testing, the video guides each step with visual clarity. Niche dimensions, ventilation gaps, and mounting points appear as precise overlays (mm/in), while numbered steps, icons, and callouts keep the layout clean. Macro shots show leveling, fittings, and door closure; sectional views clarify air circulation and cabinet positioning. Warning signs highlight critical checkpoints — alignment, minimum distances, sealing, and grounding/power — and a final checklist confirms everything is “ok.” Deliverables in 16:9, 1:1, and vertical formats ensure usability across website, e-commerce, and after-sales support.
