• Do not store or operate the appliance outdoors.
• Store the appliance in a dry place inaccessible to children (pack the appli-
ance).
Before setup: filter cartridge and water hardness
The length of time the cartridge is effective for depends on the hardness of the
water. This can be tested using the testing strips provided (strips are stuck to
the reverse side of these instructions for use)
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 at level 3

With a water hardness upwards of 21 °dH, we can no longer recommend the
use of a ultrasonic air humidifier. We recommend that you use an impeller
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, the Jack may be
operated from a drinking water filter system (e.g. Brita). Should you be unsure
about the quality or composition of the water in your area, contact the care-
taker or the provider of drinking water.
Tip
The efficiency of the cartridge can be inspected with a simple test. Hold a
small mirror in the fog for a few seconds. If there are then white deposits
(calcium carbonate) on the mirror, then the cartridge needs changing.
Setup / operation
1. Place Jack at the desired flat surface in your room. Please take care not to
place Jack on a floor sensitive to water and do not place any moisture-sensitive
appliances close to the humidifier. Plug now Jack to the power supply system.
2. Fill in the water tank (2) and place it on the humidifier. Important: Please do
not transport Jack while it is full of water. The water could spill over and run
into the electronic system of Jack.
