Power Key Press to turn the dehumidier on and off.
Timer: select timer settings key then use keys to adjust the
timer (1-24 hrs, start/ stopping timer). In power on mode the set number will represent the
number of hours the unit will run for before turning off. This will remain unaffected if unit goes
in to defrost mode or the tank is emptied than reinserted. In standby mode the set number
represents the period in hours after which the unit will start. To cancel start / stop mode press
the timer key again.
Humidity Buttons: Press the Up or Down buttons when the unit
is displaying the current relative humidity to select the desired humidity level. The humidity
level can be set between a range of 35% RH (Relative Humidity) to 80% RH in 5%
increments. Please note the desired humidity cannot be changed when the unit is in SMART
mode.
SMART Mode: This is designed for maximum convenience as it
maintains the room at an ideal domestic environment humidity
level of 50-55% RH while saving electricity. This is the default
mode and is recommended for most users.
The compressor will work until the desired humidity is reached
and then will stop;
Low Fan Mode: The fan will move the air around the room ensuring the entire air in the
room is processed and the relative humidity correctly measured. This mode gives you the
ability to adjust the desired humidity, while running the fan at a lower speed.
High Fan Mode: The fan will move the air around the room ensuring the entire air in the
room is processed and the relative humidity correctly measured. This mode gives you the
ability to adjust the desired humidity, while running the fan at the high speed. Allowing more
air to pass over the coils than in low fan speed.
When the humidity setting is finished,the appliance will be operate according to the target
setting humidity.When reaches the target humidity(the selected humidity is 2% lower than
the user selected humidistat setting), the compressor stop running,the fan continues running
for ve minutes then stopped.the swing will be shut down,but display retain.Keep this statues
for 30 minutes,the swing and the fan open,the fan running to test the current humidity,when
reachs the setting value,the compressor start running.If the current humidity can not reach the
setting value,fan will be stopped after 5 minutes,swing shut down.again to keep this status for
30 minutes,and in circulation.
For drier air/ laundry mode press the key and set to a lower percent value (e.g. 35-45%).
Laundry Mode: for the dehumidier to operate continuously with maximum water extraction
until the tank is full set the humidity level to 35%-50%RH. 35% is very dry and the unit will
work until water tank is full as 35%RH is hardly achievable in domestic environment.
Set the fan to high on laundry mode and the louvres either to swing mode or to 45 degrees
directing the airow onto clothes / laundry dryer. Do not place clothes directly over any of the

dehumidifier vents. Make sure that there is nothing blocking the hot air exhaust air flow and
for best results place the laundry within 1.5 meters of the dehumidifier.
Note:In the smart mode, through, keys set humidity of 35%, the machine is running clothes
drying modes, then the machine will have been working ondehumidification, even ifthe
ambient humidity is less than 35%, the compressor will not go down. This model applies to
drying clothes and other occasions. that if permanent drainage pipe is tted the unit will
not stop operation. Humidity set to achieve room humidity of around 35% good for quick
drying boost on initial run or emergencies, laundry mode. Not recommended for long
normal operation in domestic/ office environment. For allowing more moisture
in the air, press the humidity control key and set to a higher percent value (e.g. 60-70%).
Humidity set to 50-55% RH; recommended setting, great for domestic operation and dry
storage
