Instructions, Maintenance and Service Manual ULTRAFREEZER Series 1. GENERAL The ULTRAFREEZER series Ultra Low Temperature freezers have a storage freezing system with a temperature range from -50°C up to -86 °C. Cooling is realized by means of a cascade system, where in the highest stage (first) R507 is used as refrigerant and in the lowest stage (second) a mix of R508b and R170. -

2. TRANSPORT The Fiocchetti ULTRAFREEZERS must be transported vertically (especially for the compressors which need to be upright under all circumstances!).
