Very important: Never CUT the heating cable. This would change the cable resistance and could lead to heating cable damage or a fire. Never install the heating cable under vanities, bathtub platforms, kitchen cabinets and islands or any other fixtures. Additionally, heating cables shall not be altered in the field. If the installer or the user modifies the unit, he will be held responsible for any damage resulting from this modification, and the warranty and the product certification will be void.
