USER INSTRUCTIONS EN A B Fig. 5-06 • When a program with hot prewash is selected (see program table in the "Description of Controls" manual), extra detergent must be placed in the cavity (ref. A or B fig. 5-06, depending on models). • Only use dishwasher-specific detergents. For optimal washing results it is important to use a good quality detergent. • The detergent packs must be sealed and stored in a dry place to prevent the formation of lumps which may negatively affect washing results. Once opened the detergent packs should not be kept for too long, otherwise the detergent loses its effectiveness. • Do not use detergents formulated for washing dishes by hand, because they produce a great deal of foam and may negatively affect the operation of the dishwasher. • Add the correct amount of detergent. An insuffici t amount of detergent will result in a partial removal of dirt from the dishes, whereas an excessive amount is wasteful and does not improve the washing results. • The market offers liquid and powder detergents with differing chemical compositions, which may contain phosphates, or be phosphate-free but contain natural enzymes. • Detergents containing phosphates are more effective against grease and starch at temperatures above 60°C (140°F). • Enzyme detergents, on the other hand, are also effective at lower temperatures (from 40 to 55°C / from 104 to 131°F) and are more easily biodegradable. With enzyme detergents it is possible to obtain at low temperatures comparable results to those which can only be achieved at 65°C (149°F) using traditional detergents. For the safeguarding of the environment we recommend the use of phosphate- and chlorine-free detergents. 1293
