Page 15: 2 Function
KF 18xx/19xx Technical Information Function Electrical Supply Each appliance will be connected to its own 120VAC, 15-amp power supply. When column units are installed, there will be separate outlets for each column (see Figure 030-1). Every cooling appliance also has a main power on/off switch located inside the appliance, under the main control panel. -
Page 16: Temperature Control
KF 18xx/19xx Technical Information Temperature Control The refrigerator with a SmartFresh compartment and freezer has 2 separate cooling circuits. The same evaporator cools both the cooling compartment and the SmartFresh compartment in the refrigerator. If both areas require simultaneous cooling, then the SmartFresh compartment has priority. The cooled air passes through a flap mechanism, either directly into the refrigerator or via an air duct (set in Styrofoam in the appliance rear wall) into the SmartFresh compartment. -

KF 18xx/19xx Technical Information 1 Condenser 2 Condenser fan 3 Compressors Figure 030-3: Condenser Fan and Components (Top View) Refrigerant Stop Valve (Y30/1) The stop valve enables one compressor to channel R134a (refrigerant) to two separate evaporators. The outputs are connected to two separate capillary tubes and evaporators in appliances where more than one evaporator is needed. -
Page 18: Starting Program
KF 18xx/19xx Technical Information Starting Program The starting program operates at the time of commissioning under the following circumstances: No defective NTCs The temperature read by both the ambient air and SmartFresh NTCs is greater than 41°F (5°C) The appliance door is closed ... -
Page 19: Lighting
KF 18xx/19xx Technical Information 2.11 Lighting The bright ClearView lighting system illuminates every nook of the interior cabinet on each level to achieve maximum exposure of all contents.

Page 21: Superfrost
KF 18xx/19xx Technical Information After stocking the refrigerator with a significant amount of food, including bulky items like fresh poultry or large items like fruit and vegetable platters, engaging SuperCool will override the thermostat and begin cooling the cabinet to a lowered temperature of 35°F (2°C). SuperCool will continue working to reach this reduced temperature until it reaches this exact degree or it is disengaged by the user. -
Page 22: Drain Heater, Drain Channel
KF 18xx/19xx Technical Information At the start of the defrost cycle, the appropriate evaporator fan is switched on for 5 minutes. After 5 minutes the appropriate defrost and drain heaters are switched on. If the evaporator NTC measures a temperature of 49°F (9.5°C) or after 60 minutes, the defrost heater is shut off. -
Page 23: Vcc ® Compressor
KF 18xx/19xx Technical Information As ice is defrosted from the evaporator, it drips water into the evaporator pan below the evaporator (see Figure 030-7). This pan routes the water into the drain channel (Figure 030-8, Item 1), which is set into Styrofoam in the rear of the appliance. -
