Window air-conditioners provide a cost-effective alternative to expanding the air-conditioning system in a home or adding a system for a detached room. Installing an air-conditioner in a sliding casement window requires installing a support at the outside wall that stabilizes the outer portion of the unit. For a second-story window, enlist a professional to do the installation. Alternatively, a home-improvement enthusiast with basic skills can install a window air-conditioner at a first floor window with everyday tools and the help of an assistant.

Setting Up

1

Open the sliding panel. Remove the trim insert that borders the lower portion of the sliding panel. For a vinyl casement window, pry up the insert with a putty knife. For a wood casement window, carefully pry up the insert with a wood chisel. Save the insert.

2

Position the sliding panel so it's open halfway. Lift up on the edges, and tilt the bottom toward you, then lower the panel and remove it. Set the panel aside.

3

Measure the width of the opening between the outer edge of the stationary panel and the side of the frame where the sliding panel closes. Obtain the air-conditioner based on the width of the opening. Obtain a support kit that includes the necessary fasteners for stucco, masonry or wood and vinyl siding. Obtain an adjustable filler kit.

Support Kit

1

Set up a power or cordless drill with a screw-tip attachment. Position the platform plate from the support kit flat on the bottom of the window frame. Align the inner edge at the inner edge of the window sill with the outer portion of the platform extending outside. Measure the opening from side to side, and center the platform in the opening. Attach it to the sill with a provided screw at each of the machined holes in the edge of the platform.

2

Work from outside of the building. Position the support brace diagonally below the platform. Fit the upper end into the slot near the outer edge of the platform. Fit the inner end against the outside wall, and mark the wall at this point. Set the brace aside.

3

Use the mark on the wall as a guide, and position the steel support track horizontally at the face of the wall with the lower edge at the mark. Visually center the track below the platform. Attach the track to stucco or masonry with one of the provided concrete screws at each machined hole in the track. For wood or vinyl siding, attach it with a provided wood screw at each hole.

4

Fit the upper end of the support brace into the slot at the underside of the platform. Attach the lower end to the track with the provided machine bolt and nut. Tighten the nut with an open-end wrench.

1

Ask an assistant to help lift the air-conditioner. Position the outer end on the platform, and slide the unit toward the outside to fit the lower edge of the face-frame against the edge of the platform at the window sill. Make sure the power cord and plug are inside the room.

2

Center the air-conditioner from side to side in the opening. Secure it in place with one of the provided L-brackets and small self-tapping screws at each side of the air-conditioner case.

3

Measure the width of the open spaces at each side of the air-conditioner case. Measure from the surface of the lower window frame to the top of the case at each side. Use a utility knife to cut pieces of the flexible plastic filler to size. Slide one edge of each filler into the corresponding channel at the side of the case from above, and fit the lower edges of the fillers at the lower frame of the window.

• Wood chisel
• Measuring tape
• Power or cordless drill
• Screw-tip attachment
• Open-end wrench

• Cardboard
• Hacksaw or handsaw

Tip

• To determine the necessary capacity and output of a window air-conditioner, multiply the length of the room by the width, and multiply the result by the height of the ceiling. Divide the result by 9 to determine the cubic-footage of the room.

Warning

• Do not use an extension cord connected to the power cord for the air-conditioner, or you risk damaging the unit and overloading an electrical circuit. If necessary, enlist an electrician to install an outlet in proximity to the window and air-conditioner.
