Servicing: Make sure the appliance is switched off at the socket before service is performed on electrical parts. It is not sufficient to switch off the cabinet by the main switch as there will still be voltage to some electrical parts of the cabinet. Settings to be made before use: The following settings are to be made before the cabinet is taken into use: the season, the time setting, the weekday, the year, and choice of language. These settings are quite simple to do, and should only be done once. There are exceptions in certain situations. If the cabinet is without power supply due to power failure, or if it is switched off at the mains for more than 24 hours, the settings which may have been done, will be lost. The personal settings of the various programmes will be lost, too. The switch is located behind the control panel. To access the switch, open the panel by pulling its left-hand side outward. On switching the cabinet on, the green chilling lamp and the P key light up and "G107" is shown in the display for 10 seconds, then "OFF" is shown. The cabinet is now operating in stand-by mode.765041282 22

Program running Chilling and storage Firstly, cabinet temperature is controlled for the set period of time at the set chilling temperature. Cabinet temperature is then controlled at the set storage temperature. Storage Cabinet temperature is controlled at the set storage temperature. Proving Cabinet temperature and relative humidity are controlled at the defrost settings. Chilling, storage, retarding To allow the controls to calculate the storage time, it is necessary to set the chilling time, the defrost time, and the time of program end. Example of program for chilling, storage and defrosting Chilling is set to last 2 hours at -15°C. Storage temperature is set to -4°C, and defrosting is set to last 5 hours at 2°C. The program is set to end at 04:00 the following day. In the example, the program is started at 14:45. The program switches from chilling to storage at 16:45. The program switches from storage to retarding at 23:00. The calculated storage time is thus 6 hours and 15 minutes. Firstly, cabinet temperature is controlled for the set period of time at the set chilling temperature. Cabinet temperature is then controlled for the calculated period of time at the set storage temperature. The cabinet is heated when the program switches from storage to retarding. During retarding, the relative air humidity is continuously controlled at the set value.

After the completion of the fermentation program An extra program is built in which begins to cool down the products after the end of the fermentation process. This stops the fermentation in the products. Mode of operation and signals The time after the completion of the program is called tS. When the time tS has expired, the program section tA begins. The default value of tS is 10 minutes, but it can be regulated from 0 to 30 minutes. When the time is set to 0 minutes, the tS program is not active, and the device continues the fermentation program without pause. This corresponds to older program versions, such as G 108. When the tS program is active, the red LED lamp flashes. This is to warn the user of the extended time for the fermentation process. When program section tA begins, the cooling system begins to cool the products, and brings the temperature down to the standard value of +2°C. Now it is the yellow LED lamp that flashes, to warn that the products have been through both a normal fermentation process and the extra time tS. The yellow LED lamp continues to flash until the device is stopped completely. This is done by pressing the P button. Interruption of the programs tS and tA While the program is engaged in either the extended time tS or the actual cooling phase tA, the user can choose to press either the P or the S button. Pressing the P button will stop the device completely. If the S button is pressed, the device will return to the GA program and will continue to run this. If the S button is pressed during the extended time or the cooling phase, the red lamp will glow constantly, and the other lamps will be turned off. Setting tS and tA The settings of the two new values can be adjusted via the hidden service menu of the control system. Interrupting the automatic program before the program concludes and tS begins If the user returns to the device before the conclusion of the complete program, the user can choose to push the S button to cancel the complete program. The program will now continue its normal functioning with the GA program. For this to be done, the GA program must have entered the last quarter of its cycle. Information on the time of completion is removed through this choice, and only the temperature and humidity are shown, alternately. The two green lamps and the yellow lamp are also turned off.765041282 31

Defrost water and water flushed from the humidifier are led away through a pipe on the rear of the cabinet. A water seal must be installed between cabinet and drain.

To provide steam during proving, the humidifier must be connected to a water supply. Please note the following: The electrical conductivity of the water must be in the range: 50-800 µS/cm. The temperature of the water must not exceed 60°C. The water pressure must be in the range 1-10 bar. A shut-off valve, a check valve, and a filter if necessary, must be fitted to the supply pipe. Steam humidifier

The cabinet is equipped with a humidifier that provides steam during proving. The humidifier consists of a water tank heated by electrodes. From the tank, steam is led into the cabinet through a pipe. The tank is automatically filled from the water supply. The tank can be flushed by switching the cabinet off at the main switch and then switching it on again. In addition, the system is automatically flushed regularly depending on water quality. For further information on servicing and maintaining the humidifier, please consult the "Service and operation manual". For maintenance of the humidifier, request service assistance.765041282 33

Door closing mechanism The door is equipped with a self-closing system. The door can be opened by using the foot pedal. This leaves both hands free when filling the cabinet. Cleaning Always disconnect the cabinet at the mains before cleaning. Do not flush compressor compartment and evaporator with water as this may cause short-circuits in the electrical system. The cabinet should be cleaned internally with a mild soap solution at suitable intervals and checked thoroughly before it is put into operation again. For the external maintenance – use stainless steel polish. Do not use cleansing agents containing chlorine or compounds of chlorine as well as other corrosive means, as they might cause corrosion to the stainless panels inside the cabinet and the evaporator system. The compressor compartment and in particular the condenser must be kept free from dust and dirt. This is best done with a vacuum cleaner and a brush. The air filters on the condenser and the front panel can be removed and cleaned in a dishwasher at max. 50°C.

Service If the cabinet is to operate under optimum conditions, it is recommended to regularly have it serviced by qualified personnel. It is advisable to let the cabinet enter into a maintenance plan. The refrigerating system and the hermetically sealed compressor require no maintainance. However the condenser and air filter requires regular cleaning. If refrigeration fails, first look to see whether the cabinet has been unintentionally switched off, or whether a fuse has blown. If the cause of failure cannot be found, contact your supplier quoting TYPE, PART NO and SER. NO of the cabinet. This information can be found on the nameplate.765041282 34
