5. OPERATION
NOTE: Efficiency of the dehumidifier is influenced by the air outside the room. For operating efficiency, try to avoid opening and closing the
windows and doors. For best performance, operate the dehumidifier within the usable operating temperature.
5.1. OPERATION
5.1.1. Plug the unit in to the mains socket, a beep will be heard when inserting the plug.
5.1.2. Press the “ON/OFF” switch and the operation light will illuminate, the humidity display will light to display the previous set humidity.
The initial setting for humidity is 60%, after 3 seconds the display will show the current humidity.
5.1.3. Press the humidity up or down buttons to adjust to the desired humidity required.
If the required humidity is 3% below the current humidity the unit will start automatically, if the set humidity is 3% more than the current
humidity the dehumidifier will automatically stop.
5.1.4. When setting the humidity to less than 30%, the unit will run continuously and the display will read “CO”.
5.1.5. To shut the dehumidifier down press the “ON/OFF” switch.
NOTE: If the humidity setting is greater than the current humidity the unit will not run.
WARNING! The fan motor and compressor must run for at least 3 minutes while dehumidifying.
8DO NOT start the dehumidier immediately after shutting down, allow 3 minutes before restarting.
5.2. TIMER FUNCTION
5.2.1. To set Timer for power ON mode, with the unit in power OFF state, press the Timer button (g.3.6). The Timer ON LED (g.3.1) will
icker and the current set time will be displayed. Use the Increase/ Decrease buttons (g.1.10, g.1.11) to set the required value to
between 0 and 24 hours. After 10 seconds the selected value is set and the Timer ON led will icker.
5.2.2. To set the Timer for power OFF mode, with the unit in power ON state, press the Timer button (g.3.6). The Timer OFF LED (g.3.1)
will icker and the current set time will be displayed. Use the Increase/ Decrease buttons (g.3.10, g.3.11) to set the required value to
between 0 and 24 hours. After 10 seconds the selected value is set and the Timer OFF led will icker.
5.3. DEFROSTING
5.3.1. The defrosting device works automatically at an interval of approximately every 30 minutes for a duration of approximately 5 minutes
when the coil temperature is tested to be <= minus 1oC.
The dehumidifying function will stop during the defrosting operation. DO NOT disconnect the plug or turn off the unit during the
defrosting operation. The defrosting led light (fig.3.7) will light up.
NOTE: This dehumidifier does not have a cooling function, it produces heat during the operation and room temperature will rise
by 1°C to 4°C. The temperature gets higher while it is operated in a closet, or similar. Furthermore, room temperature will rise because
doors and windows are closed and heat is produced from other appliances in the room and from sun radiation.
5.4. EMPTYING THE WATER COLLECTION TANK
5.4.1. During the dehumidifying operation, water is collected in the water collection tank. When the tank is full of water, the dehumidifier stops
operating automatically and the warning buzzer beeps twice. The unit will not restart until water collection tank has been emptied.
5.4.2. Open the door and remove water collection tank from the dehumidifier by pulling it gently outwards by holding the sides of the tank.
5.4.3. Hold the tank by the handle and carry it carefully to an emptying point.
5.4.4. Remove the plug at the bottom of the tank and slowly empty the water out of the tank.
5.4.5. Replace the drain plug and refit the tank in the dehumidifier, making sure it is properly back in place as the unit will not restart if it is
not fitted correctly.

5.5. CONTINUOUS DRAINING
5.5.1. If there is a place suitable for draining, continuous draining can be carried out. The continuous operation enables the dehumidfying
operation to continue uninterrupted. See Section 4.6.
6. MAINTENANCE
6.1. CLEANING THE AIR FILTER
6.1.1. The dehumidifying capacity is lowered when the air cleaning filter becomes clogged.
6.1.2. Open the front door of the unit.
6.1.3. Lift up the filter element from the bottom and lift out of the holder.
6.1.4. To dislodge the dust from the filter, use a vacuum cleaner or tap it lightly.
6.1.5. If the filter is very dirty, wash it carefully in water with a neutral detergent, then rinse well with clean water and leave until dry.
6.1.6. To refit the air filter locate the top of the element into the locating bracket at the top of the door and then locate the lower section into
the lower bracket.
6.1.7. Close the door of the dehumidifier.
6.2. STORAGE
6.2.1. Unplug the unit, bundle the power cord, and hang the bundled cord at the back of the unit.
6.2.2. Remove the water collection tank and empty the water out of it. Remove the tank cover and wash the inside of the tank with clean
water. The tank may be scratched if it is scrubbed strongly with a brush. DO NOT remove the float lever from the tank. Wipe off the
water on the outside of the tank with a cloth. Refit the tank cover onto the tank and replace the tank in position.
6.2.3. Clean the air filter (see 6.1).
6.2.4. When the unit is to be stored for a long time, wipe the dehumidifier over with a dry soft cloth. To remove dirt, wipe over with a very
