1. INTRODUCTION
1.1. Presentation
The EUROCOMBI is a new free-standing combined refrigerator (with a refrigerator compartment in the upper
section and the freezer in the lower section) 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. The temperature inside the refrigerator compartment is controlled by a flap-operated
mechanical thermostat.
The Eurocombi range consists of eight models, with ALFA or DELTA stylings. All models are arched doors.
The differences between the various models consist in the size of the refrigerator and freezer compartments
and therefore in the number of shelves and drawers.

1.2. Eurocombi: total no-frost
The Eurocombi 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 air is circulated by the fan.
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 governed 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 Eurocombi 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 section 4,
page 16).
