OPERATION INSTRUCTION OF KEYS

• ON/OFF: Press ON/OFF, the unit runs in a circulation “ON-OFF-ON”.
• Humidity up and down: Press “humidity up and down” for once, the set humidity will increase or decrease by 1%. Press the key for 1.5 seconds and the set value will increase or decrease by 1%. Press continuously with the speed 5 points per second.
• Memory Key: Press the memory key and the mem-ory indicator will light on to start the function of memory when the power cuts off. Press the memory key again; the memory indicator dies to shut off the function of memory when the power is cut off.

START ON

• Plug on the unit gives off “di”.
• Press “ON/OFF”, the running indicator lights on, and the humidity display window lights on to display the previ-ously set humidity. The initial humidity setting is 60% and 3 seconds later the humidity display window lights on to display current humidity.
• Press humidity up or down key to adjust the humidity needed. If the set humidity is 3% less than current hu-midity, the unit runs; if the set humidity is 3% more than current humidity, the unit stops running.
• When set humidity is less than 30%, the unit dehumidifies continuously, and the humidity display window reads “CO

SHUT OFF

Press “ON/OFF” when the unit is running, the unit stops running and all indicators die.

NOTICES:

• When the set humidity is higher than current humidity, the unit will not run.
• When the tank is full, the tank full indicator lights on, meanwhile, the compressor and the fan motor shut off automatically, and the buzzer gives off “DD” sound. Unless the tank is emptied, the buzzer gives the “DD” sound every 5 minutes. Only after emptying the tank the unit will start running again.
• When dehumidifying, the fan motor and compressor must be running at least for 3 minutes, once the compressor starts on. It is strongly forbidden to restart the compressor again within 3 minutes after the shut off.
• When operating in low temperature, the unit judges the system temperature automatically to defrost. When defrosting, the defrosting indicator lights on, the compressorruns but fan motor shuts off automatically.
• When you press the memory key, the controller will record current humidity even if the power is off. The unit will run under previous mode after power supplied again.
• The humidity display window shows humidity from 30% to 90%.
• Keep the unit unplugged if not used for a long time.

CONTINUOUS DRAINAGE:
Take out the tank, open drainage gate at the bottom of tank, connect pipeline, fix the tank back, and pull the pipeline out from the bottom of the machine.

MAINTENANCE AND SAFETY

• FIG. 3 Do not use any relay, prolonged wire or adaptor. Otherwise, it might result in fire, radiation, or an electric shock.
• FIG. 4 Do not put the unit nearby stove or heater. Otherwise parts of unit might melt down or even catch fire.
• FIG. 5 Do not use the unit in the direct sunshine, wind or rain. (only for indoor usage)
• FIG. 6 In case of any other problems (for example smell of scorch ), please shut off the unit and unplug it. Otherwise, it might result in fire, electric shock or other malfunctions.
• FIG. 7 Do not use the unit in places easily affected by chemicals. Strong chemicals might damage the unit and cause the leakage.
• FIG. 8 Please unplug the unit when not used for a long time.
• FIG. 9 When cleaning, shut off and unplug the unit. Otherwise, it might result in an electric shock.
• FIG. 10 When draining continuously, put the drainer for smooth drainage. If the ambient temperature is as low as freezing, do not drain continuously.
• FIG. 11 Do not repair or disconnect the unit yourself. Otherwise it might result in fire or an electric shock.
• FIG. 12 Put the unit stably. If the unit turns over, the water will flow out from the tank and damage the objects nearby. Moreover, because of the damage, it might result in fire or an electric shock
• FIG. 13 Make the filter more endurable. When off for a long time, seal the filter in a plastic bag.
• FIG. 14 Do not use the unit near water. The unit might be damaged when soaked in water, so as to result in fire or electric shock.
• FIG. 15 Use the standard electric source of 220-240V/~50Hz. Otherwise it might result in fire or electric shock.
• FIG. 16 Do not damage the wire. Do not put anything heavy on the wire or heat or pull the wire. Otherwise it might result in fire of an electric shock.
• FIG. 17 Clean the dirt on the plug and fix it tightly. If the plug is not fixed tightly, it might cause an electric shock.
• FIG. 18 Do not regard the plug as a switch. Otherwise it might result in fire or an electric shock.

NOTICES ABOUT UNIT OPERATION

• When moving the unit, do not tilt over 45°to avoid any damaging of the compressor.
• The unit should be operated between 5°~32°.
• When dehumidifying, because of the heat resulted from the running compressor, the indoor temperature will rise by 1°~3°. Such a reaction should be considered as normal.
• When indoor temperature is below 10°, and the ambient absolute humidity is quite low, it is unnecessary to use the machine.
• Air inlet and air outlet should be at least 10cm away from the wall.
• Try to keep the room closed to enhance the dehumidification effect.
• Too much dirt on the filter affects dehumidification, may even result in malfunctioning of it, thus it should be cleaned at least once a month. If there is a great amount of powder in the air, the filter must be cleaned once a week, or even every day. Pull the front panel out and clean the filter. If necessary, you may slightly knock all over the filter, use a vacuum cleaner to remove bigger pieces of dirt or even wash the filter in warm clean water (≤40% with some neutral detergents) and then dry it.
