Disconnect the power before dismantling, assembling or cleaning.  Avoid touching any moving parts of the appliance. Never insert fingers, pencils or any other objects though the guard.
Do not leave children unsupervised with this appliance. Do not clean the unit by spraying it or immersing it in water.
Never connect the unit to an electrical outlet using an extension cord. Never operate this appliance if the cord, power adapter or plug is damaged. Ensure the power cord is not stretched or exposed to sharp objects/edges. Any service other  than regular cleaning or filter replacement should be performed by an authorized service representative.
WARNING: THE APPLIANCE MUST WORK IN THE VERTICAL POSITION. DO NOT TURN IT OVER!

The dehumidifier must be stored and transported vertically, otherwise irreparable damage to the compressor may occur. You should wait for 24 hours with the appliance upright before starting the appliance. Failure to do so may damage  the unit and void the warranty.
If you turn off the dehumidifier, wait 10 minutes before turning it back on. This prevents the compressor from being damaged.
CAUTION: NEVER CONNECT THE APPLIANCE TO AN EXTERNAL TIMER, OR REMOVE THE DEVICE FROM THE OUTLET WHILE IN OPERATION. Use only the ON / OFF button located on the control panel to turn the unit off.  Failure to comply with this safety precaution could damage the appliance and void the warranty.
Always place the unit on a dry and stable surface. The appliance should not be installed in laundry or wet rooms. The appliance must be placed in a room without sources of ignition (for example: open flames, an operating gas appliance or  an operating electric heater).
R290 refrigerant gas complies with European environmental directives. R290 has a low GWP (Global Warming Potential) of 3. This air conditioner contains around 280 g of R290 refrigerant gas. Refrigerant gas may be odorless.
Do not use or store in an unventilated space with an area smaller than 18.2 m2 per unit.
The room must be such as to prevent stagnation of possible leaks of refrigerant gas as there could be a danger of fire or explosion should the refrigerant come into contact with electric heaters, stoves or other sources of ignition.
Do not use the product and contact the retailer for advice, if damage has occurred to the unit which may have compromised the refrigerant system. The refrigerant system should not be perforated or punctured.

ENERGY SAVING AND UNIT SAFETY PROTECTION TIPS

• Do not cover or restrict the airflow from the outlet or inlet grills.
• For maximum performance the minimum distance from a wall or objects should be 50cm.
• Keep the filters clean. Under normal conditions, filters should only need cleaning once every three weeks (approximately). Since the filters remove airborne particles, more frequent cleaning maybe necessary, depending on the air quality.
• For the initial start-up set the fan speed to maximum and the thermostat to 5 degrees lower than the current temperature. After, set the fan switch to low and set the thermostat to your desired setting.
• To protect the unit, we recommend not using the cooling function when the ambient temperature is higher than 38ºC.

FEATURES

• 4 in 1: Cooling, Heating, Venting & Dehumidifier.
• Recommended for rooms up to 38 m2.
• 24 Hours Start / Stop Timer.
• Digital Thermostat.
• Remote Control.
• Auto-Restart to retain the settings in the event of power failure.
• Castors for Enhanced Portability.

OVERVIEW OF THE COMPONENTS

INSTALLATION

WARNING: Before using this unit, please keep it upright for at least 3-4 hours.
This unit can easily be moved from one room to another. While moving the unit please note that it must always be kept upright and then placed on an even surface.

1. Attach the fishtail connector to the end of the hose, by extending the end and twisting until firmly attached (At least 3 full rotations).
2. Attach the connector on the opposite end of the pipe to the exhaust outlet on the rear of the appliance by putting into position and twisting to lock in place.
3.  Make sure the unit is upright and there are no obstructions to their inlets and outlet grills.

INSTALATION OF WINDOW KIT

NOTES:

• The window kit is only designed to be installed with sliding or sash windows or doors.
  The window kit is not designed or to be used with any other style of windows.

• The fish tail adaptor can be used without the slide bar with most windows / doors.

• When using the air conditioner ensure that the opening left around the fishtail is as small as possible as the cooling will be less efficient.

• The best form of installation is through a wall duct. By properly venting you expel hot air from your room while efficiently cooling it.

• Your air conditioner should be used without the vent pipe in dry mode. When using dry mode ensure that an external water tank is used, monitored and regularly emptied before overflowing. Permanent plumbing can be also  installed for dry mode or an external uplift water pump can be set up for unattended use.

1. Partially open the window and place the extended slide bar in position before closing the window onto it.
2. Fix the fishtail adaptor into the opening on the slide bar.
3. Fix the exhaust connector on the opposite end of the exhaust hose to the exhaust outlet on the rear of the air conditioner.

Important Safeguards!

• The length of the soft hose extends from approximately 30 cm to 180 cm. If hose is extended above this length, the unit may malfunction which can invalidate the warranty.
• The outlet vent must be well ventilated and not obstructed as this will cause the unit to overheat.
• Keep the hose as straight and short as possible and avoid bending the air hose by more than 30 degrees in order to maintain the performance of the unit. Excessive bends in the hose may prevent the unit from expelling the hot air,  which can lead to internal damage which would invalidate the warranty.

MULTI PROTECTIVE FUNCTIONS

Frost protection
In COOL, DRY or AUTO modes, if the temperature of the exhaust is too low, the machine will automatically stop operating until the temperature has risen.
Overflow protection
When the water in the internal water tank exceeds the warning level, the machine will stop operating and sound an alarm with the LCD display showing “E4”. To resume operation empty the internal water tank. After the water is emptied,  the machine will automatically return to the original state.
Auto-defrost
The machine has automatic defrosting function. If during operation the temperature of the internal coils drops too low, the unit will enter auto defrost and the heating symbol will flash on the control panel.
Automatic thermal protection
To protect the service life of the machine, the machine has automatic thermal protection. If the temperature within the unit is outside of the specified range, the compressor and the lower motor will stop operation. The appliance will  automatically return to normal operation after the temperature of the machine recovers.
Compressor protection
To prevent damage to the compressor there is a 3 minute delay start protection function.

EMPTYING THE INTERNAL WATER TANK

Manual drainage
When the internal water tank is full the unit will stop working.
Shut off the unit and unplug. Try not to move the model abruptly as this may cause the water in the internal tank to spill out. Place a tray under the lower water plug or place the unit in a drainage area.
Unscrew the drain plug cap and remove the rubber stopper – water will drain from the internal tank. Put the rubber stopper back and screw the drain plug cap back into place.

Continuous drainage
Unscrew the drain plug cap and remove the rubber stopper.
Connect a water pipe to the upper water outlet.
You can plumb this pipe into your current plumbing system, lead it outside and use gravity fall or use a water pump.

NOTE:

• This model has a self-evaporative function, which reduces the need to empty the water tank. If the unit is vented correctly most of the water is reused to cool the condenser coils and any excess is evaporated.
• Please do not use continuous drainage if you intend to use the self-evaporating facility.
• When using the unit in heating mode, it is advisable to use continuous drainage.

CLEANING AND MAINTENANCE

WARNING: Please turn off the unit and unplug from the mains before cleaning or performing any maintenance!
