1. INTRODUCTION
This manual describes NOFROST models loaded with R600a refrigerating gas.
There are three basic models and the only difference between them is 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-driven evaporator in the freezer compartment is then distributed through the
refrigerator and freezer compartment by the fan located above the battery.

REFRIGERATOR COMPARTMENT (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.
