Before setup: Anticalc cartridge and water hardness (optional ac-
cessory)

The anticalc cartridge reduces the limescale in the water and the undesir-
able emission of limescale particles into the surroundings. Effective for one 
to three months, depending on water hardness (see table).

With a water hardness above > 7 ° dH, we recommend the use of 
the anticalc cartridge (19) to inhibit lime deposits.

 Test your water's 

hardness (= lime content) with the included testing strip (see page 4). If the 
strip shows 2 pink boxes, your water hardness is > 7 ° dH.

1. Dip the testing strips into the water for a second
2. After around one minute, the results can be seen on the testing strips. 

Some of the green boxes change colour into pink. The water hardness 
is shown by how many boxes turn pink. Example: If three boxes are pink, 
then the water hardness is > 14 ° dH.

Important:

 Soak the anticalc cartridge in a water bath for 24 hours before 

the first use (not in the water tank!). The resin has to absorb water to reach 
high performance.

The period of time that the cartridge is effective for depends on the hard-
ness of the water.

With a water hardness above 21 ° dH, we can no longer recommend the use 
of an ultrasonic air humidifier. We recommend that you use an evaporative 
humidifier to increase humidity in your house (e.g. Oskar humidifier made by 
Stadler Form).

The unit only works properly with untreated water. Do not use where there 
are water softeners and water ionisers in operation. However, Ben may be 
operated from a drinking water filter system (e.g. Brita). Should you be un-
sure about the quality or composition of the water in your area, contact the 
caretaker or the provider of drinking water.

Setting up / operation

1. Put Ben in the desired location on a flat surface. Connect the power 

adapter (1) to the unit (2) and plug the adapter (1) into a suitable socket. 

2. Lift up the water tank (3) to the side, out of the way. Unscrew the tank 

lid (4) and fill the water tank to the maximum mark (5) with clean, cold 
tap water. Then put the tank into the appliance. To do this, position the
