Freeze Prevention Control
If the copper coil temperature is below 2° after ten minutes of running, the error code E4
will display on the LCD screen. When the copper coil temperature increases to 8° the
freeze prevention will stop and the compressor and water pump will resume normal
function. It is strongly suggested not to use the cooling or dehumidifying mode when then
room temperature is too low.
Water-Full Water Level Protection
Water-level protection is done by the water-level switch. Water-level switch is always closed,
and it will open when the protection function runs.
a) When checking the water-level protection, compressor must work. After 10 seconds
of it moving, the water-level switch will go to stability that is water-level protection.
b) When the water-level is higher than the protective water-level, the water-level switch will
move (compressor is at work), the LCD displays “P2”, pls drainage (the way of drainage as
below 5th).
Auto Overheat Protective Function
To use for longer time, this model has an auto overheat protective function in heating
mode, it can protect compressor and down motor effectively (stop them from working)

the compressor runs under 3 minutes delay protection.
