Learn how to complete an 8800 VS window installation with this clear, step-by-step guide designed for RV owners and technicians. This video walks through the full process, from safely removing the existing window to properly installing and sealing the new unit for a secure, leak-resistant fit.
You’ll see how to remove interior clamp rails, cut through old sealant, and safely extract the window using proper handling techniques. The video also covers how to clean and prepare the rough opening, ensuring it is level, square, and free of debris for a proper installation.
Next, follow along as the new window is test-fitted, aligned, and installed using high-quality sealant tape. Proper positioning, including correct orientation of the sliding section, is demonstrated to help prevent water intrusion. The guide also explains how to evenly tighten clamp rails, avoid frame distortion, and confirm full flange contact.
Finally, the video shows how to check for smooth operation, inspect for gaps, and test for leaks after installation. You’ll also learn the importance of proper drainage through weep holes.
