The defendant is a trader selling instantaneous water heater geysers which operate under power current.
The defendant advertised the product with "secure direct installation", by mentioning the high voltage needed but by not informing customers about some essential features of the installation, namely the necessity to have a three-phase power supply (AC) connector, the necessity to obtain a permission for the installation from the respective network operator and the necessity to employ a specialist company for the installation of the product.
The plaintiff sued the defendant claiming that not providing this information constitutes a misleading commercial practice according to Sections 3, 1 and 5 a, 2 and 3 no. 1 UWG.
