Welcome to the TOSOT Direct Family!
We’re extremely happy to welcome you as a new member of our family! Please read
the tips below before using your product for the first time.
1. Allow the unit to sit upright for at least 3-4 hours before powering on. Shipping
carriers may set the unit on its side, which causes the refrigerant to pool in certain
areas. Standing the unit upright for 3-4 hours allows the refrigerant to move freely
within the coils.
2. Run the unit continuously for 24 hours after letting the unit stand upright for 3-4
hours. This allows the unit to work out any “kinks’ that may have resulted during
shipping from our factory or to your doorstep.
3. For more details and quick start guide about installation, please contact
[email protected] .
4. If you have any other questions, please email us at [email protected]
before making a return request. Our support team typically replies within 24 hours,
usually sooner. If you haven’t received a reply, please check your spam or junk
folder as sometimes our replies get lost in customer’s inboxes!

Window Requirements
The instructions outlined below are for standard, vertical-sliding windows. If you have
a different window type (e.g. horizontal-sliding window) you may need to choose a
different window or use a different installation procedure.
If you are installing this air conditioner in a smaller window, you may not need the
accordion subassembly. Please refer to the window size requirements for more details.
In some cases, you may need to put a small wooden block under the air conditioner
to ensure that the unit is not tilting towards the inside of your home. If the unit is tilted
towards the inside of your home, water may drain into your home and damage the
window frame, wall, or flooring. A slight angle of 5° is all it takes to ensure that water
does not drain into your home.
