Installing your Windmill W1W12 Air Conditioner correctly is key for optimal performance. Here's a step-by-step guide to help you secure it safely and efficiently:
Prepare Your Window: Begin by insulating your window frame. Use the adhesive foam provided to seal the underside of your front window sash, cutting it to the window's width. Then, insert the non-adhesive foam into the vertical side channels of your window frame, matching the height of the bottom half of the window.
Position the Air Conditioner: With assistance, carefully lift the assembled Windmill W1W12 into the window frame. Ensure someone supports the unit's back. Place the bottom bar behind the inside window sill.
Secure the Unit: Extend the side panels of the air conditioner until they meet the window frames. Use the included 1/2-inch screws to secure the unit, paying close attention to alignment. Insert the rubber plug into the center hole on the front frame.
Attach Cosmetic Panels: Measure and cut the side panels to fit your window. Insert these trimmed panels into the front frame and snap them into place.
Final Steps: Attach the sash lock following the manual's instructions. Use the remaining non-adhesive insulation foam to fill any gaps in your window. This will maximize the cooling efficiency of your Windmill W1W12.
