In order to achieve good cleaning results, the washer-disinfector needs to operate with soft water. Hard water results in the build-up of calcium deposits on instruments, etc, and in the washer-disinfector. Mains water with a hardness level higher than 0.7 mmol/l (4° d – German scale) needs to be softened. This takes place automatically in the i[...]

Reactivating the water softener Please only use special coarse grained reactivation salt with granules of approx. 1-4 mm.
