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!
