To be able to use our airvenue® in an optimal way, fill the glass container with fresh water. Do not fill in hot water! Ideally fill the glass container up to the maximum range. Here the upper maximum line of the container must not be crossed. The maximum and/or minimum of water is respectively indicated by a highlighted upper line (MAX) or a highlighted inferior line (MIN) on the glass container.
As desired, add a couple of drops of the Pro-Aqua perfumed oil or of the Pro-Aqua hygiene and care product to the water.
Put the operating unit on the device and assure that it is positioned properly on the glass container.
