MADE in the EUROPEAN UNION
TECHNICAL CHARACTERISTICSOF THE CERAMIC DISCS:
Material: Al2O3Surface roughness Ra: 0.2 µmContact surface area: 50-80%
Exclusive feature to contribute to substantial savings of energy:Many users often turn on a single-lever faucet by starting with the lever
in the mixed position, then moving it to the extreme right when cold water is desired. This initial delivery of warm water represents a waste of energy. With this model the temperature quadrant is shifted so that the normal „six o’clock” position of the lever delivers pure cold water. Thus, if the lever is turned off in the normal middle position, it will always open in the extreme cold setting. Warmer temperatures are delivered as the lever is rotated.
Models NKB-40A • NKB-40B • NKB-42C • NKB– 42DRotate-Clockwise black hot limit stop
