15. Instruction, Use and Maintenance Manual EN-IST-BZAW3-1218 1. VALVE CLEANING WITH DETERGENTS : The system in which the valve is installed must be cl eaned by expert personnel in observance of the following: - Abide by the indicated detergent concentration values ; - Observe the instructions provided by the detergent manufac turer. - Always wear protective safety glasses and gloves. IMPORTANT! - Accurately dose detergents to avoid excessive concentrat ion ; - Always rinse thoroughly with clean water after washi ng. - Check compatibility of valve materials. CAUTION! Burns hazard. The valves and piping may be very hot. Wear protective gloves WARNING After installing a new or serviced valve, perform an i nternal washing cycle before using the piping for food liquids. If it there has been any welding work, passivation treatment must be carried out.
