Guides
- Samsung WindFree: Smart Install self-test after installation
After installation the unit can test itself. The manual explains how the installer starts Smart Install and what to check if it reports an error.
- Samsung WindFree: how to clean the filter and when to use Auto Clean
The manual gives the cleaning interval and steps for the air filter and how to reset the filter reminder. Turn the unit off and wait until the fan stops first.
- Samsung WindFree: weak cooling or dripping – what is not a fault
The manual lists simple causes such as a dirty filter, sun on the outdoor unit, settings or a kinked drain hose. Regular refrigerant top-ups are not correct.
