HumSpot 3 4 3 Notes on water supply As a monopropellant jet system the DRAABE air humidifier system places special de mands on the water it is to atomise It may only be operated with desalinated and virtually bacteria free pure water Only treated water may be used That means a three stage treatment process must always be run before the water can be fed in to the HighPur All the following requirements in terms of water treatment are extremely important to en sure safe hygienic functioning The operator shall ensure that the following requirements are met on a permanent basis The requirements for a water treatment are met if a DRAABE pure water system is used Of course such systems must also be subjected to regular checking and maintenance Glossary Untreated water This is the water as it enters the treatment stage This water requires treatment Other terms for untreated water include gt drinking water and mains water Soft water See also 4 3 2 This is water which has been softened Pure water This is the water which is the product of the treatment stage Another term for pure water is gt osmosis water CAUTION Despite compliance with these requirements the possibility of bac terial contamination of the system can never be fully excluded Regular check ing of the system by the operators is essential in order to prevent harm to h
