4.1 Cleaning and maintenance

• During everyday use it is advisable to give the device a thorough cleaning at least every three days.
Also clean device 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 atomisation effect.
• You can rinse out the water tank with hot water (>65 °C) or an alcohol of at least 75 % vol. The
atomiser chamber should be cleaned using an alcoholsoaked 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. Please use the pro-vided brush to remove deposits and dirt particles
from the outlets. 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.
• When cleaning the unit, rinse the filter in clean water. If you are not using the unit for an extended
period, store the filter separately so that it can dry.
• Store the unit in a cool, dry place, preferably in its original packaging.
• Remove cap from underside of the water tank and store separately to prevent sleeve gasket from
sticking.
4.2 Water filter
Water filter
The humidifier AH 665 is equipped with a water filter. This filter assists in cleaning and demineralisation
of water. Depending on the hardness of the water used, the filter should be changed at least once
per month if the device is used daily.
Proceed as follows: Screw the lid off of the water tank and turn the filter out of the lid anti-clockwise.
Turn the new filter in the reverse direction back into the lid.
Descaling
When using hard water, or water with a high mineral content, the device must be regularly descaled.
Please use only citric acid for descaling (powder preparation from the chemist). Do not use any liquid
descaler, descaling tablets or vinegar!
- Empty out the device completely (tank and lower section).
Ensure that no liquid runs into the air outlet of the lower section.
- Place 4 tablespoons (approx.100g) of pure citric acid in the tank and fill up with 2000ml 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 lime scale
- using the brush supplied, a 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).
