Arida Oslo dehumidifier

Safety instructions

Read all instructions carefully before using the dehumidifier. This dehumidifier is intended for use in a domestic environment only. Any other use is not recommended by the manufacturer and may result in fire, electric shock or other damage to persons or property.
When using electrical appliances, basic safety precautions should always be followed:

• Do not operate the dehumidifier with a damaged cord or plug, after it malfunctions, or if it has been dropped or damaged in any way. Return it to an authorized service center for examination and repair.
• The dehumidifier should always be kept in an upright position to avoid damage. Place it on a flat and stable surface.
• Check the household voltage to ensure it matches the dehumidifier's specified rating before use.
• Use the dehumidifier in an ambient temperature between 1°C and 40°C.
• Make sure that the air inlet and outlet are not blocked or covered.
• Do not place the dehumidifier too close to curtains or other objects – minimum distance 40 cm.
• When using the dehumidifier to dry wet clothes in the room, keep the clothes at a safe distance from the dehumidifier to prevent water from dripping onto it.
• Never place anything on top of the dehumidifier or cover it with any kind of material while it is in use.
• This dehumidifier is intended for use in private homes and light office environments only, and not for commercial, industrial or outdoor use. Never use it in very humid rooms (such as bathrooms).
• To protect against electric shock, do not immerse the dehumidifier, plug or cord in water, or spray it with liquids.
• Never unplug the power cord without first pressing the "ON/OFF" button, as this may damage the dehumidifier.
• Always unplug the dehumidifier when it is not in use or when moving it. To disconnect the power supply, grasp the plug and pull it out of the socket. Never pull on the cord.
• Always empty the water tank before storing the dehumidifier.
• Using the dehumidifier in front of a hot radiator may cause it to not collect water due to the heat from the radiator.
• Do not place the power cord under rugs, rugs, or runners. Route the cord so that it is not in the way and may cause a tripping hazard.
• Never use or store the dehumidifier in direct sunlight.
• Take the dehumidifier to a qualified service technician if it needs repair. Repairs performed by unqualified persons may cause damage to the dehumidifier or personal injury and will void the warranty.
• Avoid using extension cords if possible, as they can overheat and pose a fire hazard. Only use an extension cord if you are sure it is in perfect condition.
• Do not use the dehumidifier without an air filter and ensure that the filter is kept clean to avoid malfunction and voiding the warranty.
• This dehumidifier can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the dehumidifier in a safe way and understand the hazards involved.
• Children should not play with the dehumidifier.
• Cleaning and user maintenance shall not be made by children without supervision.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

Control panel

Press the ON/OFF button to turn the dehumidifier on or off.
During setting selection, you can select the humidity level the dehumidifier should have as its dehumidification target. Hold the button down for 5 seconds to activate the WiFi connection between the dehumidifier and the WiFi router (Smart Life).
When selecting the mode, you can choose whether the dehumidifier should have the fan speed setting "AUTO", "SLEEP", "LOW" or "HIGH". With "AUTO" the dehumidifier will regulate the fan speed itself. By holding the button down for 5 seconds, you can turn the LED lighting in the water tank on or off.
Under Swing & Child Lock, you select which position the air damper should swing to. By holding the button down for 5 seconds, you activate the child lock and lock the control panel (not the ON/OFF switch).
Hold down both mode selection and swing & child lock for 5 seconds to activate ionization.

The control panel shows the humidity it measures in the room, the temperature it measures, and indicators for child lock, ionization, full water tank, WiFi activation, error message, and damper setting.

Location

Where should you place the dehumidifier? For best results, it should be placed in a central location, such as in a hallway or corridor.
Do not place it directly in front of a radiator or in direct sunlight.

For safe use

• Do not insert small objects into the device as this may damage it and pose a hazard.
• Keep sufficient distance around the device, as shown above.
• Do not remove the water tank while the unit is operating, as this may cause water leakage.
• Make sure the water tank is properly installed. If the tank is full or not properly installed, the warning light will illuminate and the unit will stop.

Troubleshooting

Problem	Possible solution
The fan runs for about 2 minutes after the unit is turned off	This is normal and not a cause for concern.
The device only works at room temperature between 1-40ºC. It stops outside this range (“HI” or “Lo”)	This is normal. The device is designed to operate within this temperature range.
The device emits an unusual odor	This is a normal and harmless by-product of the Zeolite desiccant. Odors can occur when the zeolite releases odors it has absorbed from e.g. smoke, cosmetics and furniture.
The error message icon flashes, indicating a blockage in the air intake or outlet	The filter is probably dirty or clogged. Clean or replace the filter.
WiFi light is blinking continuously and unable to connect	Make sure the WiFi network is stable
