Regulating air flow direction
Turn the roller on the air vent to control the air flow direction of the vertical louvers.
Move the air vent directly to adjust the air flow direction of the horizontal louvers.
NOTE: 1. To lenghten the compressor's life, after turning off the unit, please wait at
least 3 minutes before turning it back on.
2. The cooling system will switch off if the ambient temperature is lower than the set one. The ventilation, however, keeps working at the
set level. If the ambient temperature rises above the selected level, the cooling function will resume.
3. On the contrary, the heat will switch off if the ambient temperature is HIGHER than the set one (still, the ventilation keeps working at the
set level). As the ambient temperature drops below the selected level, the heating fu nction will reume.
4. This machine is equipped with ANTI-FROST function. While using the heating function in low temperatures, sometimes the heat will
stop for a while in order to melt the frost. As this occurs, just wait for the heating function to resume.
DRAINAGE
Although the unit is self evaporating, during high humidity levels excess water may fill the internal water tray. Depending on how high the humidity
and the duration of high humidity levels will depend on how often the unit needs to be drained. When the reservoir full :
a. For the mechanical model, the compressor will stop, only the fan will continue to circulate the air. The 'FULL WATER' indicator will light up.
b. For the electronic model, both of the compressor and motor will stop. The COMP. indicator light will flash.
To resume the cooling function, empty the water by the following steps:
1. Turn off the air conditioner and avoid moving it when full.
2. Position the water tray underneath the drain hole.
3. Remove the drain knob & rubber plug from the drain hole and allow the water to drain out.
4. When the water tray is almost full, replace the rubber plug in the
drain hole and empty the water tray.
5. Repeat until the unit is emptied.
6. Replace the rubber plug and tighten the drain knob firmly.
7. Turn on the unit - the comp light should not be flashing.
