• Housing surface: Powder-coated, similar to RAL 9003 (signal white)
• Cooling capacity at L0L32 (0 °C chamber / 32 °C ambient): 1450 watts
• Cooling capacity at L0L43 (0 °C chamber / 43 °C ambient): 1270 watts
• Control range for cold storage room: -5 °C to +10 °C
• For cold storage room volume: Up to approx. 11.1 m³ to 15 m³ (depending on the selected insulation, goods, and set temperature)
• Airflow (evaporator): 1000 m³/h
• Permissible ambient temperature: +5 °C to +43 °C (indoor operation only)
• Refrigerant: R290 (propane) – an environmentally friendly, natural refrigerant with a very low global warming potential (GWP 3)
• Refrigerant charge: < 150 g
• Global Warming Potential (GWP): 3
• CO₂ equivalent: < 0.45 t
• Defrosting: Automatic hot gas defrosting with demand-controlled cycle control
• Condensate: Automatic, integrated condensate evaporation
• Maximum permissible wall thickness: 150 mm (for the mounting cutout)
• Power connection: 230 V / 50 Hz (AC via CEE plug, blue, power consumption approx. 990 W)
• Power consumption (nominal current): 5.4 A
• Sound pressure level: 32.8 dB
• Dimensions: 828 mm x 671 mm x 976 mm (H x W x D)
• Weight: 64 kg (net)

Dimensions for the wall cutout
• Width of the cutout: 575 mm
• Height of the cutout: 395 mm

Key features
• Piggyback design: The monoblock unit is simply hung into the corresponding cutout in the cold storage room wall (“piggyback”). The maximum wall thickness may be 150 mm.
• Hot gas defrosting: The unit has an automatic, demand-controlled hot gas defrosting system with integrated condensate evaporation, so that a separate drain is usually not necessary.
• Smart electronics: Equipped with modern control, Bluetooth connectivity (for app control and data tracking), and automatic leakage detection.
• Components: Thermostatic expansion valve, pressure sensors, and efficient, internally finned heat exchangers.

Important application notes
• Ambient temperature: The device is designed exclusively for operation in closed rooms with an ambient temperature of +5 °C to +43 °C. It does not have a winter control system and is not weatherproof (no outdoor installation).
• Accessories for Viessmann cells: If the WMC3 unit is mounted on a classic Viessmann cold storage room, a special adapter cable and a converter box are usually required to connect the door contact switch and the power supply correctly.
