8.1 Recommendations for optimal use of energy, water and additives
Use the machine fully loaded when possible
This shall prevent detergent, rinse aid, water and energy waste.
Detergent and rinse-aid
Use detergent and rinse-aid chemicals with high biodegradability, to respect the environment best. Verify the proper
dosageinrelationtowaterhardnessatleastonceayear.Excessofproductpollutesriversandseaswhileaninsucient
dosing will cause unsatisfactory dish washing and/or hygiene.
Tank and boiler temperatures
The tank and boiler temperatures are set by the manufacturer in order to obtain the best washing results with detergents on
