MULTIPLE PROTECTION FUNCTIONS
1. Anti-frozen protection function
Under COOL mode, when the compressor continuously runs over 10 minutes, if tube
temperature is ≦2℃/36℉ for 20 seconds, the anti-frozen protection function will be on, E4 will
be shown on LCD display, compressor and water wheel motor will stop working, but upper fan
remains running; If tube temperature≧8℃/46℉, the unit will stop anti-frozen protection and
recover to the original working condition. Compressor will re-start working with 3 minutes delay
for protection.

When the water volume exceeds its alarm level in chassis, warning sounds automatically and

unit is not shut down manually, the unit will recover to the original operating status automatically
once the water is fully drained. Or connect the power to re-start the unit again.
