Page 5: Introduction
1. INTRODUCTION This manual deals with the Zero Degree COMBI refrigerators produced in the Susegana factory (ZS). It is a two-compressor combined appliance with PNCs: 925 703 xxx (KBI0280 DOD). The cooler/zero degree and freezer compartments are independent; therefore it is possible to switch them on/off according to the necessity. - Page 6 5 sensors detect the temperatures: cooler sensor (placed near the fan); zero degree sensor (placed on the cell in the Zero Degree compartment, right-hand upper drawer); battery evaporator sensor (placed on the battery); freezer sensor (placed on the cell in the freezer compartment, right-hand upper drawer); room sensor (placed on the circuit board for the display).
- Page 7 The cold produced by the battery-type evaporator, which is located (behind evaporator shield) in the Zero Degree compartment, is introduced first into the Zero Degree compartment and then into the refrigerator compartment by a fan located behind fan housing. Air is drawn in by this fan (located at the top of the cell), flows through the ducts, and descends to reach the battery-type evaporator.
- Page 8 NOTES: 1. Depending on the models, in place of the air filter there is a duct which contains a polyester isolating panel; 2. The 0 degree compartment drawers feature sliders for the “humidity control“ function: slider closed to maintain humidity; slider open not to maintain humidity.

2. REFRIGERATING CIRCUIT The battery evaporator is positioned in the Zero Degree compartment and it is available as spare part. The battery evaporator does not feature defrosting heaters or thermal cut-outs. The tower-type evaporator of the freezer compartment is available as spare part. Along the edges of the cabinet frame there is the anti-condensation coil. -

Page 12: Operation
4. OPERATION The 0 DEGREE COMBI refrigerator, being a two-compressor operates with different modes depending if the 0 degree, refrigerator and freezer compartments requires cooling. There is only one compressor for the cooler and 0 degree compartment; therefore there are 3 possible combinations of normal operation: a. -
Page 13: Defrosting Cycle On The Battery-Type Evaporator
d. Defrosting cycle on the battery-type evaporator The ice that accumulates on the battery-type evaporator is regularly defrosted. Defrosting takes place every time the compressor has operated for a sum total of 4 hours. The defrosting cycle starts after the compressor shuts off. During defrosting: the compressor does not operate the fan operates continuously at HIGH speed... -
