Window Air Conditioner 3

When it comes to cooling your home during those hot summer months, an air conditioner, like the LG 8000 BTU, can be your best friend. However, installing an air conditioner can seem like a daunting task. But don’t worry, this comprehensive guide will walk you through the process step-by-step, ensuring you can enjoy a cooler home in no time.


To install an LG 8000 BTU Air Conditioner, first gather the necessary tools and materials. Insert the guide panels on the air conditioner and attach the seal strip to the window. Install the L brackets, set the AC in the window, and extend the guide panels to fill the window opening. Seal the window and fasten the support bracket. Remember to ensure that the rear of the air conditioner is tilted downward for proper drainage and that there are no obstructions behind the unit. If unsure, hire a professional.

Essential Tools and Materials

Before you start, ensure you have the necessary tools for installation. These include:

  • Screwdriver
  • Scissors
  • Pencil
  • Ruler
  • Hammer
  • Level

The window installation kit for the LG 8000 BTU Air Conditioner typically includes:

  • 11 Type A and 5 Type B screws
  • 3 L brackets
  • 1 adhesive seal strip
  • 1 seal
  • 2 guide panels
  • 1 support bracket
  • 1 drain joint pipe and drain washer

Installation Steps

Step 1: Insert the Guide Panels

Insert the guide panels into the guides of the air conditioner. Fasten the curtains to the unit with four type A screws on each side.

Step 2: Attach the Seal Strip

Cut the seal strip to the window width, remove the backing, and attach the seal strip to the underside of the window.

Step 3: Install the L Brackets

Measure and mark the centerline of the inner sill. Then, measure and mark another line 8 inches above and below that center line. Install 2 L brackets behind the inner window sill, centered on the lines drawn above and below the center line with the short side of the bracket as shown. Ensure that the bracket edge is flush against the back of the inner sill and use type-A screws to secure.

Step 4: Set the AC in the Window

Carefully set the AC in the window, so that it is centered and placed with the front edge of the bottom guide against the back edge of the sill. While setting the AC, bring the window sash down behind the upper guide of the AC unit. The air conditioner should tilt slightly downward at the back if it is set up properly. This ensures proper drainage.

Step 5: Extend the Guide Panels

Extend the guide panels to fill the window opening and secure them using four type B screws – 2 on the top, and 2 on the bottom.

Step 6: Seal the Window

Cut the seal to the window width and stuff the sash between the glass and the window to prevent air and insects from getting into the room. Fasten the L bracket using a type-A screw.

Step 7: Fasten the Support Bracket

Remove the screw from the right side of the AC cabinet. Fasten the support bracket using the screw removed from the cabinet and attach the support bracket to the inner window sill with a type- B screw.

Additional Tips for Efficient Installation

  • Ensure that the rear of the air conditioner is tilted downward by about 10 to 15mm (1/2 inch) to ensure that the condensed water can be smoothly drained toward the backside.
  • Block the gap near the wall or the product with insulation material provided in the package.
  • There should be at least 20 inches of open space behind the unit, so that the heat may discharge properly.
  • Avoid having curtains that will be pulled into the air conditioner’s front grille as it will reduce the cooling efficiency of the unit and can lead to frost accumulating on the coils.

By following these steps, you can ensure a safe and efficient installation of your LG 8000 BTU Air Conditioner. However, if you’re unsure about any part of the process, it’s best to hire a professional to avoid any potential damage to your new AC unit or your home.
