Product Introduction & Features
Evaporative air cooling is a natural way of cooling, similar to a breeze flowing across the water which drops
the temperature at the beach, and has a relaxing cooling effect on people.
When water as a liquid evaporates in to the air, the result is a mixture of air and water molecules. This
chemical change requires heat, thus energy or latent heat is taken from the air molecules - dropping the
actual temperature of the air.
Air contains dust, pollen and other pollutants. The evaporative air cooler cleans the air providing cool, fresh,
clean healthy air.
For best operating performance position the unit in a location that will create a “flow through” air effect.
The greatest cooling effect will be felt if the unit is operated in a partly opened doorway or window with the
“cool” conditioned air directed into the room to be cooled. It is important to also have a door or window
partly opened away from the cooler to create this “flow through” effect.
On days of high humidity, the cooling effect may be significantly reduced as the air entering the filter may
already be saturated with moisture. On days like this it may be better to switch the cooling feature OFF and
operate the unit as a fan only.

OPERATING INSTRUCTIONS
A. ON/OFF
-Insert the power plug into a power point and switch on. The ON/OFF indicator light will illuminate.
-Press the ‘ON/OFF’ button on the control panel (or remote control). The unit will start in the default
“LOW” speed as indicated by the indicator light and Normal Mode.
B. MODE: There are 3 mode functions, Normal, Nature or Sleep.
•Normal mode: Constant air flow and can be adjust via pressing the SPEED function button. Example:
Normal LOW or Normal High or Normal Medium.
•Nature mode: The “Nature” variable speed wind mode automatically selects one of three variable
speed wind speed patterns. Each pattern produces a different wind pattern depending on the speed
setting selected. Nature mode can be operating HIGH or MEDIUM or LOW speed.
•Sleep Mode: The “Sleep” variable speed window allows you to set the product so that the wind
speed will decrease gradually from a high speed to low (depending on the original fan speed selected
by the user).
The variable speed wind speed will simulate the flow of an evening breeze slowing to a light variable
speed night breeze.
The pre-set programming for each setting is as follows:
➢If the fan speed control is set to “High”, the appliance will start will the High Nature variable speed
wind setting.
➢The airflow will remain on “High Nature” variable speed wind for approximately half an hour, the
drop to “Med Nature” variable speed wind for approximately half an hour and finally drop to “Low
Nature” variable speed wind unit it is manually turned off or the timer setting is finished.
➢If the fan speed control is set to “Mid”, the appliance will start with the “Mid Nature” variable speed
wind setting. The airflow will remain on the mid setting for approximately half an hour, the finally
drop to “Low Nature” variable speed wind until it is manually turned off or the timer setting is
finished.
➢If the fan speed control is set to “Low”, the appliance will remain on the “Low Nature” variable
speed wind setting continuously until it is manually turned off or the timer setting is finished.

CAUTION: To avoid of electric shock, you must always switch off and unplug the fan before cleaning.
C. SWING:
•Press the button if you want the vertical louvers to swing from left to right.
•Press it again to stop the vertical louvres from swinging.

CARE & CLEANING
To ensure effective humidifying and filtering, it is recommended that the filtering system be cleaned once
every 1-2 months.
NOTE: If the power cord set of this appliance becomes damaged, discontinue use. Repairs should be
undertaken only by a qualified technician.

•Your appliance must be switched OFF via the main power supply and unplugged, and allow it to cool
down before proceeding with any cleaning, assembling or disassembling.
•Remove any water which is left over in the water tank. Take the appliance outside and remove the
drain plug in the rear of the unit. Water will pout out from the bottom of the appliance. Replace the
drain plug when empty.
•Be careful not to tip or knock the appliance over.
•Clean the air cooler regularly especially the rear air inlet filter. Do not allow this filter to become
blocked. This can be cleaned by using a vacuum cleaner hose with a brush attachment. Ensure the
mesh is dry before vacuuming. Alternatively, the mesh can be removed for washing. To do this,
loosen the screw and then pull the mesh out. Wash using a soft damp cloth or rag and mild
detergent, then wipe dry. Refit the mesh and clip it securely into place.
•Clean the housing with a damp cloth, a vacuum cleaner or a dusting brush.
•We recommended lightly running a vacuum cleaner brush nozzle over the louvers to remove any
dust or dirt that may have accumulated.
•Never use flammable or abrasive cleaning agents such as benzene or spirits to clean the appliance.
•Never immerse the appliance in water.
STORAGE
•Your appliance must be switched OFF via the main power supply and unplugged and allow it to cool
down before proceeding with any cleaning, assembling or disassembling.
•Ensure all water is removed from the appliance. Allow the unit to run for 1-2 hours without water so
it dries quicker. More time may be required depending on how humid the ambient air is.
•Coil the power cord loosely and place it next to the unit.
•Remove the batteries from the remote control.
•When the appliance is totally dry, store in a dry well-ventilated area.

TROUBLESHOOTING
Always check full product operation as detailed above before returning any product as faulty.
On humid days the unit may not appear to be cooling correctly. This is due to the air already being saturated
with water. Adding more water to the air will not result in reducing the air temperature. In these conditions,
it is advisable to operate the unit as a fan to circulate room temperature air.
