Page 4: Safety
REVERSE OSMOSIS SYSTEMS RO 4... /E /EL - INSTRUCTIONS MANUAL Safety 1.1. General The equipment has been designed and constructed according to D.P.R. n° 459 of 24th July 1996 (regulation for accomplishment of Norms 2006/42/CE, 91/368/CE, 93/44/CE and 93/68/CE regarding the unification of States members laws in so far as machines are concerned). It has been designed and constructed according to European Norms UNI EN 292-1, UNI EN 292-2, UNI EN 292-2/A1, UNI EN 418, CEI EN 60439-1, CEI EN 60 204-1. -
Page 5: Principles Of Working
REVERSE OSMOSIS SYSTEMS RO 4... /E /EL - INSTRUCTIONS MANUAL Principles of working Osmosis is a natural phenomenon : it is the spontaneous passage of a liquid from a dilute to a more concentrated solution across a semi-permeable membrane. The driving force of the solution through the membrane is its osmotic pressure. -
