1. INTRODUCTION
This manual describes the NOFROST models WITH ELECTRONIC TIMER.
These models differ from the previous (see SM 599356104) as they do not feature the electromechanical timer
because an electronic timer has been incorporated in the control and power board called ERF1050-01.X (where
X represents a variant of the board).
The three basic models differ only for the volume:
260 litres (ex C9, pnc 925886…), 262 litres (ex C10, pnc 925887…) and 290 litres (ex C11, pnc 925888…).

The NOFROST refrigerators consist of a refrigerator compartment A and a freezer compartment B.
The cold, produced by the battery evaporator in the freezer compartment, is then distributed in the refrigerator
and freezer compartments by the fan placed over the battery.
NOFROST REFRIGERATORS WITH ELECTRONIC TIMER 6/29
REFRIG ER AT OR CO MPARTMENT (A)
The air is pushed by the fan down the foam duct at the bottom of the compartment: it enters by nozzle 1 and
comes out of nozzle 2. Manual flap C enables to regulate the flow of cold air and therefore the temperature
inside the compartment.
The thermostat bulb is located inside the flap and reacts both to the air temperature of the air coming out of
nozzle 2, and to the air temperature inside the refrigerator compartment.
The air returns to the air compartment through the foam duct at the bottom of the compartment, entering from
nozzle 3 and leaving from nozzle 4.
FREEZER COMPARTMENT (B)
The cold air is pushed into the compartment by the fan through the two nozzles 5 and 6. After circulating, the air
is rechannelled to the evaporator battery through opening 7, under the protection panel.
