Congratulations on your purchase of this dehumidifier. Please read this instruction manual
carefully before you use this dehumidifier.
Drier air offers greater comfort at higher room temperatures. Lower humidity reduces
growth of mold, fungus and bacteria, while creating a more conductive environment for
storage of most applications.
Besides human comfort, Dry Air storage is used for numerous applications such as Strong,
Libraries, Electronic equipment rooms, Hospitals, Pharmaceutical Storage Area, Archives,
Laboratories and for other hygroscopic material applications.
Bacteria and mould requires a high humidity to survive and multiply. If the humidity is kept
below 50% relative humidity.
Corrosion - iron and steel will not rust if the air in contact with the surface has humidity
below 50% relative humidity.
The air is laden with moisture, however the volume of moisture able to carry at any given
temperature is limited (termed saturation vapor (content). Beyond this, vapor returns to
liquid (water) state of its gaseous state.
Based on this principle, air conditioner and a refrigerant dehumidifier cools the air, lower-
ing the saturation level and thereby promoting condensation. However, an air conditioner is
controlled by its thermostat which is less effective and less efficient while a dehumidifier is
controlled by a humidistat or hygrostat which provides the desired humidity level.
Relative Humidity is a measure of how much moisture is in the air. It is the ration that
indicates the ability of the air to absorb more moisture, expressed in percent (%RH). For
more information, see also specific / absolute humidity.
The lower the percentage of RH, the lower the moisture content in the air and the greater
the air’s ability to absorb more moisture. When the air reaches 100% RH, it reaches its
saturation point and the water vapor turns to liquid, forming droplets of condensation.
1. When using electrical appliances, always apply basic safety precautions to reduce the risk
of electrical shock, fire or injury to person.
2. If the electrical supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons.
3. Do not connect the unit to any AC electrical socket that is damaged.
4. Use only a 220-240 Volt outlet, DO NOT USE MULTIPLE EXTENSIONS or
ADAPTERS with this appliance.
5. Always switch off at the power socket when not in use and before unplugging.
6. Do not use the following locations or similar:
7. Never insert your finger or other foreign objects into grills or openings. Take special care
to warn children of these dangers.
8. Always store the unit upright in order to maintain the compressor in proper working
condition. Leave the unit upright for at least 30 minutes before operating.
9. Always unplug the unit before cleaning.
10. Remove filter and clean with a vacuum cleaner or wash with mild detergent. Do NOT
wash with hot water or in the washing machine or dishwasher. Do NOT dry under direct
sunlight.
11. Do not spray water on the dehumidifier.
12. Empty the tank before moving the dehumidifier.
13. The unit is fitted with an auto defrosting operation and starts when the evaporator
generates frost. The function ensures continuous running when the temperature is down
to 5℃.

1. Important note - leave dehumidifier upright for at least 30 minutes before operating.
2. Connect to a power outlet and switch on. The indicator “RUN” will flash.
3. Press “ON/OFF” button once, “RUN” indicator will stay lit and the “HUMIDITY%”
display will show the room humidity level.
4. Press the “UP” or “DOWN” button to set the desired humidity value.
5. The dehumidifier will start to operate if the room humidity is higher than set a value.
Otherwise, it will not operate.
6. The fan will start running, followed by the compressor after approximately 3 minutes.
This is safety procedure.
7. HUMIDITY SETTING - Set value moves by 1%.
8. When set value is below 26%, the sign “CO” will appear on the screen indicating
Continuous Operation.
9. TIMER ON - On standby mode, press the TIMER ON button to set the Timer. The Timer
On LIGHT will flash and the Display Screen will show the selected time. Press the “UP”
or “DOWN” button to select the desired time between “0” to “24” hours. The Buzzer will
sound if there is no override for 5 minutes, and the TIMER ON Light will turn on.
Pressing the TIMER ON button again will cancel the setting.
10. TIMER OFF -On running mode, press the Timer Off button to set Timer. The Timer On
Light will flash and Display Screen will show the selected time. Press the “UP” or
“DOWN” button to select the desired time between “0” to “24” hours. The Buzzer will
sound if there is no operation for 5 minutes, and the TIMER OFF Light will turn on.
Pressing TIMER OFF button again will cancel the setting.
11. AUTOMATIC Timer Controlled mode - The dehumidifier will operate ON & OFF
automatically at 24 hour cycle.
12. Automatic DEFROST mode - When the room temperature is lower than 15℃ or the
evaporator coil temperature falls below 2℃ for more than 10 minutes, the unit will
automatically Defrost. In this mode, the compressor will not operate, but the fan will
continue running at high speed. The “DEFROST” indicator will stay lit during this time.
Removing Collected Water
1. This dehumidifier discharges collected water directly by a drain pipe/hose.
2. Direct the hose to drain outlet or outside of the room.
3. Ensure there is no kink or drastic bend on the hose.
4. CAUTION - Always inspect for any damage on hose as any water leaked into the room
contributes to increasing the humidity in the room.
Important
Ensure power plug is disconnected and unplug from anelectrical socket.
Do NOT use petrol, thinner or other chemical cleaners to clean unit.
Do NOT wash the unit directly under a tap or hose. This is unsafe and electrical
components may be damaged.
Cleaning Exterior Parts
Use a mild soap and water solution to clean exterior parts if necessary. Dry after cleaning.
Cleaning the Filter
The air filter removable and washable. Remove the air filter located at the back of dehumid-
ifier. The filter should be washed with mild soap solution and water. Allow the air filter to
dry before reinstalling. Torn or damaged filters should be replaced. The filter should be
cleaned at least once a month or more frequently is used in dusty conditions.
