The contents include:

1 medisana AH 661 humidifier
1 instruction manual

The packaging is recyclable or can be recycled back into the raw materials cycle. Please dispose of unwanted packaging materials properly. If the damage caused during transport is noted while unpacking, please contact your retailer immediately.

WARNING
Keep packaging away from children! Choking hazard!

Ultrasound Technology
Very dry air increases susceptibility to infection and respiratory diseases and leads to fatigue and lack of concentration. Healthy air should have a relative atmospheric humidity of 40 to 55 %. The quiet, energy-saving ultrasound technology of the personal humidifier uses oscillation to convert water into a fine mist that increases the moisture level of the air. This improves the air quality and prevents the mucous membranes and skin from drying out. The capacity of the device is suitable for a room with a maximum area of 30 m². Pay special attention to the notes on cleaning and care.

CAUTION
Excessive intensive use can result in an oversaturation of the ambient air which can precipitate on walls, windows, and objects in the room. It is, therefore, necessary to regularly check using a hygrometer that the relative humidity does not exceed 55%.

CAUTION
Ensure that the humidifier is secured against toppling over and operated on a moisture-resistant surface. Precipitation/accumulation can occur particularly when using mineral water/aromatic essences. The mist outlet is rotatable. Ensure that the escaping mist is not directed toward other electrical devices, furniture, or walls.

Filling and emptying the water tank
Before you switch on the device for the first time, leave it for half an hour at room temperature. Detach the water tank from the device and turn it over. Unscrew the cap 2. Rinse out the water tank and then fill it up with a maximum of 3.2 l drinking water. Seal the tank again by screwing cap 2 back in. Turn the water tank over again and place it back in the device so that it audibly engages. Do not move the unit when the water chamber is full. Dispose of the leftover water after use and rinse out the tank with fresh drinking water. Before using it again, fill the tank with fresh drinking water. When you have switched off the unit and do not intend to use it for an extended period of time, remove and empty the water tank.

CAUTION
Only use fresh drinking water (max. 40°C) in the device. You can also use demineralized water if the water is very hard and calciferous. Clean the device at regular intervals and remove lime and other deposits, to maintain its efficiency. Do not pour the aroma oil directly into the water tank.

Switching the unit on and off
When required, pull out the aroma compartment 11 and add a few drops of aroma oil to the compartment. Put it back in its original position. Plug the device into a properly installed power socket.
Switch on the device by touching the on/off button 6 once. The integrated control LED lights up. After a few seconds, the mist from outlet 1 will be visible. Switch off the device when not in use or if there is no water in the tank by touching the on/off button 6 again. The device switches itself off automatically when the water tank is empty. With a full water tank, the maximum operating time is approx. 10 to 14 hours.

Pre-warming
The device has a prewarming function for destroying germs and bacteria. To activate this function, touch button 9 after filling the water tank. The integrated control LED over the button lights up. With an activated prewarming function, the nebulization performance of the device improves. The nebulization performance is max. 250 ml per hour with cold water and max. 350 ml per hour with warm water.
Intensity adjustment
By multiplying by touching the intensity button 7 you may control the mist intensity in 3 levels (low “L” / medium “M” / high “H”). The respective LED over the button lights up.
Timer
This device features a timer, with which you may preset the operating time. By repeatedly touching button 8 you may select between 2, 4 or 6 hours of operating time or “OFF” (= deactivated timer). The respective LED over the button lights up.

Faults and Fault Remedying

The device will not switch on (LED not illuminating): Plug in the plug; Check the power circuit, socket, and fuse.
No mist: Fill the water tank.
No mist although tank full: Close the lid properly
Mist intensity too weak:
Too much residue in the water canister, clean the ultrasonic transducer/water is too dirty, replace it.
White deposits: Use clean water or at least 1/2 distilled water / 1/2 fresh tap water.
Unusual smell: Polluted or stagnant water, clean the tank and fill it up with fresh water.
Unusual noise: Insufficient water in the tank, fill up with water/device is not on a solid surface, place on a stable and level surface.

If a fault cannot be remedied using the described method, please contact your service center.

Cleaning and maintenance

During everyday use, it is advisable to give the device a thorough cleaning at least every three days. Also clean devices before and after long storage periods.
Before cleaning the device, make sure that it is turned off and the mains plug is removed from the socket.
Remove the water tank from the device and empty it.
Clean the outside of the unit with a soft, damp cloth.
Please do not use any aggressive substances for cleaning, such as scouring cream or other detergents, as these may damage the surfaces and reduce the atomization effect.
You can rinse out the water tank with hot water (>65 °C) or alcohol of at least 75 % vol. The atomizer chamber should be cleaned using an alcohol-soaked cloth and cotton bud. Take care to ensure that no water gets inside the humidifier.
The ultrasound generator is the most sensitive component in the device. It is important for it to be kept clean and handled with care. Use e.g. a cleaning brush to remove all the residue and dirt particles. Never clean the ultrasound generator using metal objects.
If you do not intend to use the unit for an extended period of time, empty any remaining water from the tank and dry off the unit.
Store the unit in a cool, dry place, preferably in its original packaging.
Remove the cap from the underside of the water tank and store it separately to prevent the sleeve gasket from sticking.

Descaling
When using hard water, or water with high mineral content, the device must be regularly descaled.
Please use only citric acid for descaling (powder preparation from the chemist). (No liquid descaler!
No descaling tablets! No vinegar!).

Empty out the device completely (tank and lower section). Ensure that no liquid runs into the air outlet of the lower section.
Place 1 tablespoon (approx. 25g) of pure citric acid in the tank and fill up with 500 ml of water at 60 °C. Screw the tank shut and gently shake until the citric acid powder has dissolved.
Place the tank on the lower section. DO NOT SWITCH ON THE DEVICE!
Allow the descaling solution to cool in the tank/device (at least 3 hours).
Remove the tank from the device and, with a suitable brush (bottle brush or similar), scrub the interior and the mist chamber. Empty the contents of the tank and rinse well.
Empty the lower section. Make sure no liquid gets into the air outlet. Rub off persistent limescale using a brush, cloth, or cotton buds. Take care around the ultrasonic transducer!
Rinse the lower section well (Ensure that no liquid runs into the air outlet of the lower section).
