Let’s get started!
Step 1: Testing
Before you install the AC, let’s test it to make sure it made it safely to your home and your outlet
is proving proper power. Place it on a flat surface, plug it directly into a wall outlet, and turn it
on. Next use the Mode button on your control panel and put the AC into 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 on to the next step. If not, see detailed troubleshooting tips
at tclusa.com/support.
Step 2: Installation
A few quick notes before installing:
• This unit is made to fit inside a standard double-hung window.
• Check the size of your window before installing.
1. Use the (4) included 3/8” screws to fasten the top mounting rail to the unit.
