Manufacturer instructions
The Sealey SACWK1 Window Sealing Kit is designed to improve the efficiency of portable air conditioners by preventing warm air from re-entering the room. It is suitable for various hinged windows and skylights with a total perimeter of up to 300cm. Installation is straightforward: clean the window frame and the window edge thoroughly to ensure the adhesive backing sticks properly. Apply the supplied self-adhesive hook-and-loop tape along the perimeter of the window frame and the corresponding edge of the window itself. Attach the fabric sealing material to the hook-and-loop tape. The kit features a double-zip design, allowing you to open the seal, insert the air conditioner exhaust ducting through the opening, and zip it securely around the hose to minimize gaps and maximize cooling performance.
