3.1. Freezing protection control:
If the temperature in the outlet pipe drops too low in the cooling, dehumidification
or energy saving mode, the air conditioning unit will be automatically switched to
the protected status. When the temperature in the outlet pipe increases above a
specified value, the air conditioning unit returns to normal operation mode.

10
3.2. Overflow protection control:
When the water level in the water reservoir exceeds an alarm level, the air
conditioning unit gives an acoustic warning signal and the ‘WATER FULL’ indicator
starts flashing. In this case, connect the drain hose to the outlet of the air-
conditioning unit, put the other end into the waste or a collection container and
drain water from the air-conditioning unit (see the Drainage instructions). After
draining the water, the air conditioning unit returns to its original operating state.
3.3. Automatic defrosting (this is only available on the models with the cooling
function): The air conditioning unit is equipped with an automatic defrosting
function. Defrosting is carried out using a four-way reverse valve.
3.4. Compressor protection:
In order to extend the service life, the compressor is equipped with a protective
function of a three-minute delay of restarting the compressor after it has been
switched off.
