- Page 6 Location When receiving the product, check the packaging material for damage. If any damage occurs at the packaging material, it should be considered if the product might have been damaged too. If the damage is substantial, please contact your dealer. The transport pallet can be removed by loosening the screws that fasten the pallet to the product.
- Page 7 When installing / building in this product, it is imperative to ensure proper ventilation around the cabinet. In order to do so, the following demands must be met. Minimum free height above the cabinet 500 mm Minimum free space behind the cabinet 50 mm (distance created by the two distance pieces mounted on the back of the cabinet) Do not obstruct any ventilation openings in the appliance enclosure or in the structure for building in.

Information about the climate class applicable for the different products can be found at the name plate (see fig.7)
- Page 10 Fig. 4 Always disconnect the power if interruptions in power supply occur, and when electrical parts are removed/put on, and before cleaning and maintenance of the product. Repairing of electrical/technical parts may only be performed by authorized technicians with proper knowledge of the product. Do not use the product before all coverings are installed, so that live or rotating machine parts cannot be touched.
- Page 11 During normal operation, some parts of the refrigeration system in the compressor compartment might reach high temperatures and could therefore cause burns if touching these components. Do not use electrical devices inside the product. To ensure correct and efficient air flow in the cabinet, the shaded areas must be kept free of items.

- Page 13 Connect the cabinet to the mains. Please note! During maintenance and repairs, it must be ensured that the unit has no voltage applied to it. So take the plug out of the socket, or shut off the power! It is NOT enough to switch the unit off with the START/STOP button, since the unit in such case still has the mains voltage applied to it.
- Page 14 Initial defrosting of the evaporator (connection when the unit is cold) If the unit is in use and it is cold in the room, the program starts with a defrosting cycle: In connection with this, the display shows the temperature internally within the unit. The defrosting symbol is lit up: Do not use mechanical devices or other means to accelerate the defrosting process!
- Page 15 Display of the setpoint (temperature setting) in the storage program Press the button, and hold it in. The display then shows the "desired value" and thereby the temperature setting. Setting of the setpoint (temperature setting) in the storage program Press the button, and hold it in.
- Page 16 Time-controlled cooling "HCL" This program is time-controlled only. The air temperature and the temperature of the contents of the cabinet are not taken into account. Both compressors perform the cooling in parallel. The second compressor starts 15 seconds after the first one. When the proper evaporator temperature is attained, the fan will be running audibly with a very high RPM figure (SF900plus).
- Page 17 Temperature-controlled cooling (Hard Chill) This program cools down to the selected, desired value at full motor power (controlled with the use of the extra sensor). Both compressors perform the cooling in parallel. The second compressor starts 15 seconds after the first one. When the proper evaporator temperature is attained, the fan will be running audibly with a very high RPM figure (SF900plus).
- Page 18 Temperature-controlled cooling (Soft Chill) This program gently cools down to the selected, desired value (controlled using room sensor). Both compressors perform the cooling in parallel. The second compressor starts 15 seconds after the first one. The fan runs at a high RPM figure (SF900plus). The program is started by pressing the button Temperature changes with Soft Chill: The program is governed solely by the room sensor.
- Page 19 Thawing program In connection with thawing, a defrosting heating element is used, which is governed by the temperature that the room sensor measures. The thawing program is only able to start when the desired temperature value is set to between +2 C and +8 C. The program is started by pressing the button starts the function.
- Page 20 The user menu The user menu is opened by pressing the button for approx. 3 seconds. Navigate through the menu using the using the buttons, after which the selected menu item is opened with the button . The buttons increase or decrease the value.
- Page 21 Dry cooling Dry cooling function may only be selected via the user menu. The user menu is opened by pressing the button approx. 3 seconds. The function can now be switched in or out under the DC menu item, saved with , after which the menu is exited with Menu item...
- Page 22 Display Explanation If "F3" is displayed, there are problems with the condensation sensor. This sensor only protects against overheating, and it has no influence on the temperature regulation in the cabinet. It ought however to be replaced as quickly as possible, so the protection against overheating is re-established Faults in the second condensation sensor in connection with units with two cooling motors (see fault message "F3").
- Page 23 Door monitoring When the door is opened, "OP" is shown in the primary display. An acoustic signal is emitted, and the "A1" message is shown on the secondary display, if the door at a minimum is open in "Dad", and "BU" is connected. The acoustic alarm is deleted by pressing .
- Page 24 Defrost water The appliance produces water during defrosting, which is led into a tray under the product. An electrical heating element, placed in the tray, re-evaporates the water. It is recommended to clean the tray and corresponding parts at least once a year. Remember to disconnect the cabinet before cleaning.
- Page 25 Door closing mechanism The door is equipped with a self-closing system. If the door is opened less than 90 , it will close by itself. If the door is opened more than 90 , it will stay open. The door can be opened by using the pedal door opener. This leaves both hands free for placing foodstuff inside the cabinet.
- Page 26 Door gaskets This chapter deals with the importance of a well-functioning door gasket. Gaskets are an important part of a refrigerator/freezer. Gaskets with reduced functionality, reduces the tightness of the cabinet. Reduced tightness might cause increased humidity, internal icing, an iced-up evaporator (leading to reduced refrigeration capacity), and in worst case reduced lifecycle of the cabinet.
- Page 27 Service The refrigerating system and the hermetically sealed compressor require no maintenance - they merely must be kept clean. If refrigeration fails, first investigate whether the unit has been unintentionally disconnected or switched off at the socket, or whether a fuse has blown. If it is not possible to find the cause of the refrigeration failure, please contact your dealer.
