Defrosting of the refrigerator cannot be completed before defrosting of the longfresh
compartment is finished as the refrigerator is always defrosted at the same time the longfresh
compartment is defrosted.
4.2. Defrosting in continuous operation
Should the appliance for any reason switch to continuous operation (rise in ambient
temperature, faults in coolant system, overloading ...), then refrigerator and longfresh
compartment are defrosted after 10 h compressor operation, to avoid insufficient cooling due
to excessive ice build-up.

Refrigeration technology and automatic control technology - functional principles
5.1. Freezer
The Santo 2941io longfresh is equipped with a conventional 4-star freezing compartment.
This freezing compartment operates completely independent with respect to refrigeration and
control technology. The following description therefore relates mainly to the refrigerator and
longfresh compartment.
5.2. Refrigerator and longfresh compartment
The refrigerator incorporates a back panel evaporator, the longfresh compartment is
equipped with a U-evaporator (i.e. at the back and side).
5.2.1.Magnetic valve
By means of the magnetic valve, cooling can be directed optionally to the refrigerator and the
longfresh compartment or only to the longfresh compartment. Two types of valves are fitted
in series: the monostable Danfoss-3-way valve Type 0904 or the bistable Elbi-3-way valve.
If voltage is applied to the Danfoss-3-way valve, then the longfresh compartment only is
cooled. Switch-over of the Elbi-3-way valve is by voltage impulses.
