It’s strictly forbidden to remove and/or tamper with any safety device.

 

Children or unassisted disabled persons are not allowed to use the appliance. 
Do not touch the appliance when barefoot or parts of the body are wet or damp. 
Do not clean the unit when the power is ‘ON’. 
Do not pull, remove or twist the  electrical cables coming out from the unit, even if it is disconnected from the main 
power supply. 
Do not step with your feet on the appliance, sit down and/or place any type of object. 
Do not spray or pour water directly on the unit. 
Do not  dispose  of, abandon or leave within reach of children packaging  materials (cardboard, staples, plastic bags,
