I asked our supplier, who replied as follows: "The waste water hose to the MDK11 must have a diameter of 15 mm. This can be attached with a hose clamp."
Hello f.schmid the MDK11 can be connected to a 17mm inner diameter hose. The condensate can then be drained directly into the shower or another drain. Please note, however, that condensation water (like distilled water) has a lower pH value than drinking water and may have a slightly corrosive effect on sensitive surfaces. Best wishes and have fun dehumidifying with the Swedish brand Wood`s - the dehumidification specialist. Manuel Rupp
