Open the carton and remove the below parts.
Tip! Before unboxing, cut the tape along the top of the box to loosen contents inside. Once you lift and remove the box, check the inside of the box as some parts may be stuck at the top. You can find the screws and other parts located in the tray beneath the AC unit.

Before you install your AC, let’s test it to make sure it made it safely to your home and your outlet has the proper power level to run your AC. Place it on a flat surface, only plug it directly into a wall outlet (never use a power strip or other device), and turn it on. Next, use the Mode button on your control panel to change the AC to Cool Mode and press the down arrow to set the temperature to the lowest setting. After 3 minutes, the AC should be blowing cool air. If so, please continue to the next step. If not, see detailed troubleshooting tips at supporttcl.
A few quick notes before installing:

2. Fasten the accordion styled window panel expander pieces to the unit. They are marked “Right” and “Left”. Pull the leading edge of them to its maximum width. Then slide the panel expanders into the grooved notches (slide downward) on the sides of the unit, and make sure they are inserted into the metal rails tightly.

3. Carefully place the window air conditioner into the window where it is to be installed (2 people are recommended for this step). Close the window securely. The AC unit should be slightly tilted to the outside area to allow water to drain out from the unit.

4a. Fasten the air conditioner to the window frame, using the included ½” screws. Fasten each of the panel extenders (Left and Right). You may have to drill a pilot hole in the window frame to fasten these screws to the window sash.
4b. Attach the lock frame between the panel extender and the window sill and fasten them together with the included ¾” locking screw. Repeat for each side.

4c. Attach the sash lock between the top of the sliding window and window frame, using 1 of the included ¾” screws to secure the window closed.

4d. To prevent outside air from entering the room, insert the foam top window gasket. You can cut the foam top to match the width of the window.

5. Plug the unit into the electrical outlet as specified above in the electrical requirements. Set the unit to Cool Mode.

In SLEEP mode, the air conditioner will automatically adjust the temperature and fan speed to make the room more comfortable during the night. The set temperature will automatically raise every 30-60 minutes, and at most change six times until the set temperature is 81 or 82 degrees.
7. Filter Button – After the fan motor runs for 500 total hours, the Filter Check light will turn on to remind the user to clean the filter. After you clean the filter, you can turn off the light by pressing the Filter button.
You may hear a pinging noise, caused by the water hitting the condenser on rainy days, or when the humidity is high. This design feature helps remove moisture and increase efficiency. You may hear the thermostat click when the compressor cycles on and off. Water will collect in the base pan on rainy days, or high humidity days. The water may overflow and drip from the unit on the outside. The fan may run, even when the compressor is not on.
