²⁾  In case of continuous, long-term operation below +5 °C ice might form on the evaporator if outer humidity is allowed to enter the chamber, for instance, by open apertures, doors or if additional humidity is generated by specimens or others.

    In these cases, the evaporator has to be defrosted from time to time by heating-up to 3+10 °C.
