3. Safety instructions for the operator The following instructions are designed to ensure safe operation of the machine: Only use the machine if you have been instructed in its operation and workings. Operate the machine only as described in these operating instructions. Do not open any panels or machine parts for which a tool is required. When handling detergent and clear rinse, observe the warnings printed on the respective packages. Wear protective gloves for any jobs which have to be performed inside the tank while the machine is in operation or during the daily shut-down process. In the event of faults not attributable to the on-site water or power supply, contact the Winterhalter after-sales service. Do not put any safety devices (e.g. door catches, etc.) out of operation. 4. General information on washing glasses Glass drinking vessels are hygienic and quick and easy to clean. In order to get the most out of your glasses, you should observe the following important points for handling glass: What to look for when buying glasses - The dimple in the base of the glass should be as small as possible. - Do not choose glasses with thick rims, as these prevent the water film from draining off properly after washing. - Thick bases (e.g. for weissbier glasses) take a long time to cool down and can easily lead to breakages. - Extremely tall, thin glasses are always more difficult to clean than normal-sized glasses. Important features of glass racks - Glass racks are designed in such a way that the glasses are washed at a slight angle. This intensifies the rinsing effect and enables the water to run out of the dimple in the base more easily. - Glass racks are made of plastic or plastic-coated wire so as not to damage the glasses. - Never use damaged glass racks. If the plastic coating shows signs of damage, replace the rack. Points to observe in glasswashing machines - Never wash glasses in a dishwashing machine, as the higher temperatures inside the dishwasher will eventually corrode the glass, leading to cracks and opaqueness. - The optimal temperatures for washing glasses are as follows: Wash: 58 C Rinse: 65 C - Never clean ashtrays in the glasswashing machine!

How to avoid breakages - Do not polish glasses after washing them. Not only is this unhygienic, but the mechanical pressure also puts a strain on the glass. - Do not use cold water or ice to cool glasses down quickly after the wash. A cold rinse in the machine also puts a strain on the glass. - Store clean glasses in closed cupboards. Do not put glasses away upside down, as this may damage the rims. - Do not stack glasses on top of each other. How to avoid odours - Use a non-perfumed detergent and clear rinse. We recommend the Winterhalter products "F-30 and "Klarspüler N, for example. - Do not store glasses in rooms used for cooking and frying. - Do not hang clean glasses above the bar, as cigarette smoke can become trapped inside them. - Do not place glasses on absorbent cloths, etc. to dry, but remove the rack from the machine after the wash cycle and leave the glasses on the counter for 1-2 minutes to dry inside the rack. We recommend that you obtain a second rack so that you can be filling one rack while the other is inside the machine. What to do about stains, streaks or lack of shine - This is a job for the experts: get a Winterhalter service technician to inspect the machine. Wash water - In order to avoid mineral deposits and hard spots on the glasses, the water should be pretreated. You can determine which type of water conditioning is suitable in your case by taking a water sample. We will gladly assist you in this, and can supply you with the necessary water softening unit. Detergents and clear rinses - We recommend our own clear rinse, "Gastronom-Klarspüler. The clear rinse is dosed automatically via a dispenser. - We also recommend our own detergent for glasses, "GASTRONOM flüssig 30. The detergent is dosed automatically via a dispenser. Before putting your glasses in the machine - Before your glasses are washed in the machine for the first time, they must undergo thorough preliminary cleaning by immersing them in a bath of water. Put your entire stock of glasses in a bath consisting of 10l of water at a temperature of approx. 60 C and 100ml of "GASTRONOM F 8400 detergent. Once the water has cooled down enough for you to put your hands in, clean all the glasses inside and out with a brush or coarse sponge (caution: rubber gloves should be worn), then wash them in your glasswashing machine according to these instructions. You can also clean the glasses in the machine. For this purpose, add 50 ml or "GASTRO- NOM F 8400 detergent to the tank water and wash the rack containing the glasses three times. Then take the glasses out of the machine to dry. Winterhalter Gastronom GmbH Pf. 1152 D-88070 Meckenbeuren OI GS24 890009794 05/00 sch P.3
5. Operating and indicating elements 1 Power switch: Press this button to switch on the machine (lights up when actuated). Press it again to switch off the machine (light is extinguished). 2 Indicator lamp When this lamp is extinguished, the detergent solution has reached "heating up": the prescribed temperature. 3 Programme: Press this button to initiate the programme cycle (lights up while the programme is in progress). Optional extras: 4 Indicator lamp This lamp lights up if there is a fault in the detergent supply or if "detergent dosing": the detergent container is empty. 5 Indicator lamp This lamp lights up if a regeneration of the water softening is "water softening": necessary. 6. Before the wash Before the wash can be started, the machine must be made ready for operation: - Turn on the on-site main switch. - Open the on-site shut-off valve. - Check the inspection slits in the front panel to see whether there is enough detergent and clear rinse in the respective containers. Top up if necessary. Make sure that no detergent gets into the clear rinse container when filling and refilling. Never mix up the detergent and clear rinse containers! Winterhalter Gastronom GmbH Pf. 1152 D-88070 Meckenbeuren OI GS24 890009794 05/00 sch P.4
- Check that the surface strainer is correctly positioned in the wash tank. The surface strainer is accessible when the rotating rinse arm is tilted backwards and the wash system is tilted to the left-hand side. - Insert the standpipe and turn slightly to make sure it is sealed tight. - Check that the wash system and rotating rinse arm are correctly positioned (they should both be in the bottom position). - Turn on the power switch (1) (lights up). The tank is then filled automatically and detergent is added to the tank water. The heating time depends on the temperature of the incoming water. The temperature of the incoming water must not exceed 60 C. Once the required temperature has been reached, the indicator lamp "Heating up (2) is extinguished and you can start the wash cycle. 7. The wash cycle - Place the dirty glasses in a rack suitable for the type of glass in question. The glasses must be inserted upside down. Leave a space between the glasses, otherwise they will rub against each other and become dulled or scratched after a short time. - Slide the filled rack into the machine and close the door.

- Press the "Programme button (3). The button lights up while the wash programme is in progress. The wash cycle is now executed. The programme lasts approx. 2 minutes, which is equivalent to 30 racks per hour. The main wash cycle, during which the glasses are cleaned intensively, is followed by a 12s rinse cycle. The specified programme time is only possible provided the machine is connected to the hot water supply. In the case of cold water connections, the main wash cycle is not completed until the rinse water has reached the required operating temperature of 65 C. The wash cycle is completed when the "Programme button is extinguished. - Open the door, tilt the rack slightly to allow the remaining water to drain off more easily, and take the rack out of the machine. Thanks to the specific heat of the dishes and the influence of the clear rinse added to the rinse water, the dishes dry squeaky clean within a short time. It is advisable to place the glasses upside down on a fine plastic grid to dry, or to leave them in the rack. Drying with a tea-towel is superfluous and may even damage the glasses. 8. After the wash - Turn of the power switch (1), take the rack out of the machine and remove the standpipe. This causes the tank to be emptied. Automatic wash tank cleaning - Close the door again and turn on the power switch (1). The tank filling process is then activated via the rinse cycle and the tank area above the surface strainer is cleaned. This process should only be executed for approx. 5-10 seconds. - Tilt the rotating rinse arm and wash system upwards. - Scrape all the dirt residues which have settled near the surface strainer onto the strainer and remove it from the machine. - Check the pump suction strainer and clean it if necessary. - Clean the surface strainer thoroughly and reinsert it in the machine.

- Clean the outside of the machine with a soft cloth and suitable cleaning agents. We recommend the use of Winterhalter stainless steel cleaner and Winterhalter stainless steel polish. The machine is not hoseproof, and must not therefore be sprayed with high-pressure or steam-jet cleaning devices. - Leave the machine door open after the cleaning process (a catch is provided in the door for this purpose). Machines with built-in drain pumps: - Open the door of the machine, take out the rack and remove the standpipe. In the case of machines with built-in drain pumps, the drain pump starts up automatically when the door is opened in the switched-on state. This allows the waste detergent solution to be pumped out on removing the standpipe. - Once the detergent solution has been pumped out, turn off the power switch (1). - Continue cleaning the machine as described above. 9. Faults The machine is equipped with an automatic low-water alarm which causes the "Programme 1 button (3) to flash if the tank has still not been filled with water after approx. 8 minutes. If the low-water alarm flashes: - Check whether the standpipe is inserted correctly and whether the on-site shut-off valve is open. - Then activate a new filling process by turning the power switch (1) off and on again. Should the low-water alarm continue to flash, please contact your Winterhalter after-sales service representative.

10. Special information Please use only detergents and clear rinses which are suitable for commercial glass washing machines. We recommend that you use our own products, which have been specially developed for our machines. Should the tank water become exceptionally dirty on certain days due to intensive washing, it should be drained off and the tank cleaned and refilled. During the daily cleaning procedure, make sure that no rusty foreign bodies remain on the floor and walls of the tank, as these can even cause "stainless steel" to rust. Such rust particles may originate from cleaning utensils or non-rustproof supply pipes. Besides daily cleaning, the machine must also undergo thorough maintenance at least twice a year. This should be performed by an expert (trained at the Winterhalter works). When buying new or additional glasses, we recommend that you only buy those which are labelled by the manufacturer as "suitable for dishwashers". Protect the machine from frost, otherwise water-consisting systems could freeze and thereby be destroyed. 11.

12.3 Frost protection The machine can also be operated or stored at temperatures below 0 C. In this case, after shutting down the machine each day as described (see: "After the wash"), you will need to open all the drain cocks at the rear of the machine in order to empty all the water systems (boiler, pump, solenoid valve). The metal hose (supply hose) must also be emptied. Once the machine has been fully drained, close all the drain cocks again and re-connect the metal hose.
