Getting started The following models are comprised in this manual: > KPS 20, 40, 60, 90, 120 and 180. > The models in this manual are all termed as “cabinets” although KPS 120 and 180 are rooms that you can walk into. > Some functions or properties can deviate from cabinet to cabinet. Differences will be mentioned. Figure 1: General use of the cabinet. > The KPS cabinet is not a storage cabinet. Therefore the cabinet does not defrost automatically.
Composition of this manual. > This manual is divided into the following two parts: Compulsory part (page 4 - 13) Complementary part (page 14 - 27) > The compulsory part deals with basic functions. Knowledge of these is required for correct use of the cabinet. Use of display images.
Installation and preparation Installation Installation continued. Correct installation of the cabinet before usage. > To ensure reliable operation make sure the following is observed: > The cabinet must be located in a dry and ventilated room. > The cabinet is designed to operate in ambient temperatures of up to +30°C. Avoid location in direct sunlight or near any heat sources, i.e. an oven. The cabinet must not be located in a chloride/ acid-containing environment (swimming-bath etc.

If defrosting is not necessary the cycle will not be activated. > Activates an IFR cycle. IFR automatically adapts the cycle to the characteristics of the food item. Using the IFR facility, surface frosting cycle will be minimised. See page 17 under “IFR” for further information. > Activates a blast freezing cycle (Quick negative chill key).
Maintenance Cleaning Defrosting water If cleaning is insufficient, the cabinet may not work efficiently or it may cause malfunctions. As a KPS cabinet does not re-evaporate defrosting water the following should be noticed: > Before cleaning isolate the cabinet from the electrical supply. > The KPS 60, 90, 120 and 180 must be led to an external drain. > The cabinet should be cleaned internally with a mild soap solution at suitable intervals.
Service The refrigeration system and the hermetically sealed compressor need no inspection, only cleaning. > 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 Gram’s technical department.
