Page 4: General Principles
General Principles The UV 400 SERIES sterilizers have been planned specially for destroying harmful bacteria and viruses present in your water. Their working is based on a physical principle which is a warrant of security: the output of ultra- violet irradiation. - Page 5 Attention: Working on live equipment is forbidden. INSTALLATION GUIDANCE The reactor control panel utilises air cooling. The following guidelines must be adhered to when locating the unit. The reactor and control panel must not be located in a position where the ambient air temperature exceeds 40ºC.
