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.
