This document describes the Bosch GUN21.. Freezer, an under-counter appliance designed for freezing food and making ice cubes in private households and enclosed domestic environments, up to an altitude of 2000m above sea level.
The freezer compartment allows for storing frozen food, freezing fresh food, and making ice cubes. The temperature can be set between -16 °C and -24 °C, with -18 °C or lower recommended for long-term storage of perishable food. The low temperatures slow down or stop spoilage. The appliance features a fully automatic NoFrost system, eliminating the need for manual defrosting in the freezer compartment. It also includes a 2-star freezer area for temporary storage of non-delicate food (e.g., ice cubes) for up to 14 days, with temperatures between -12 °C and -16 °C depending on the main freezer compartment setting.
The appliance's permitted room temperature depends on its climate class, which can be found on the rating plate. For climate class SN, the permitted room temperature is 10 °C to 32 °C; for N, 16 °C to 32 °C; for ST, 16 °C to 38 °C; and for T, 16 °C to 43 °C. The appliance is fully functional within these ranges and can operate at temperatures as low as 5 °C for SN climate class without damage. Niche dimensions are crucial for installation: a recommended niche depth of 560 mm (minimum 550 mm) and an inside niche width of at least 600 mm are required. The weight of the appliance can be up to 40 kg, so the subfloor must be sufficiently stable. Freezing capacity, refrigerant type, cubic capacity, and other technical specifications are detailed on the rating plate. Information about the model can also be found online via the EU EPREL product database. The appliance is network-capable with Home Connect functionality, supporting WLAN home networks (Wi-Fi). It operates on 2.4 GHz band (2400–2483.5 MHz) with max. 100 mW and 5-GHz band (5150–5350 MHz + 5470-5725 MHz) with max. 150 mW.
The control panel allows users to configure all functions and view the operating status.
Regular cleaning and servicing are important for efficient long-term operation.
The manual emphasizes several safety warnings:
