1. Introduction
1.1. Presentation
The EUROFLEC is a new free-standing combined refrigerator, based on the EUROCOMBI model, but with
different versions produced in the Fuenmayor factory in Spain.
This appliance features a single compressor and a total no-frost system. The operating cycles are controlled
electronically. A flap-operated mechanical thermostat controls the temperature inside the refrigerator
compartment.
The EUROFLEC comprises various models which differ from each other in the different size of the freezer
and refrigerator compartments and therefore in the number of shelves and drawers.
The PNCs of EUROFLEC model start with 928 405 xxx as for the EUROCOMBI model, therefore, in order to
know which model it is, you need to check the power board which has been installed by referring to the
specific spare parts list and to the following table:

1.2. EUROFLEC: total nofrost
The EUROFLEC is a total no-frost appliance, and as such its operation is based exclusively on the battery
evaporator in the freezer compartment, which cools the air; the fan circulates the air.
A duct embedded in foam channels the cold air into the refrigerator compartment, where the flap-operated
mechanical thermostat regulates the flow of cold air and thus the temperature inside the refrigerator
compartment. The air returns to the freezer compartment through two outlets located at each side of the
vegetable drawer.
Operation of the compressor (switching on and off) is controlled by an NTC sensor located externally (in air)
in the freezer compartment. The electronic system periodically defrosts the ice which accumulates on the
evaporator battery; defrosting terminates when a second NTC sensor, positioned in contact with the
evaporator battery, detects a temperature of +15°C.
The main characteristic of the control system used in the EUROFLEC is the fact that the defrost operating
cycles are not of fixed duration, but calculated on the basis of the time required for defrosting (see chapter
5).
