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.
