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. The split-type air conditioner is a heavy object, which needs two or more people
to lift and install. Failure to do so could result in injury or other accidents.
2. Allow the unit tosit 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.
3. Some parts with sharp edges may cause injury, so gloves are highly
recommended for unpacking and installing.
4. Run the unit continuously for 24 hours after installation. This allows the unit to
work out any “kinks”that may have resulted during shipping from our factory to
your doorstep.
5. If you have any problems with your product, please send us an email before
submitting a return request, as there might be a simple solution for your issue.
