Page 4: Section 1 - Product Familiarization
Section 1 - Product Familiarization A Refrigerator for a Different Kind of Consumer The new Dacor Built-in Refrigerators provide a new level of performance for a specialty market. This line of refrigeration products is targeted to enter into a market with little competition. -
Page 5: A New Level Of Performance For Fresh Food Storage
Temperature stratification can have a major impact on the longevity of fresh foods. To minimize this effect the Dacor Built-in Refrigerators keep the air moving in the fresh food section even when the temperatures are already at their optimum. -
Page 6: Long Term Storage With A Higher Level Of Performance
The Dacor Built-in Refrigerators look ahead and before starting defrost provides maximum cooling to the freezer compartment. The result of the maximum cooling period is lower freezer temperature. With a lower starting temperature, the defrost can take place and overall freezer temperature may rise only one degree above normal. -
Page 7: Cooling Performance That Matches The Needs
Dacor Built-in Refrigerators were designed from the start to be some of the quietest on the market. Special insulation is included to limit the noise heard outside of the cabinet. -

Something this Special Needs Special Considerations Not every kitchen in America has the right location for a refrigerator like they use in a restaurant but if there is enough space, a Dacor Built-in Refrigerators fill the spot beautifully. There are two cabinet widths. The larger of the two is approximately 48 inches wide. -

aCor aCor uilT uilT efrigeraTor efrigeraTor erviCe erviCe anual anual Setting Aside the Space Just as with any refrigerator, it is always important that you have enough space to work around the unit. The cabinet depth alone doesn’t tell the entire story. You need to consider the length of the open doors to determine the total space you need for use of the appliance. - Page 18 1 - P eCTion roduCT amiliarizaTion Setting Aside the Space (continued) The 42" product requires an area that is 41½ inches wide and 48 11/16 inches deep. Two feet of the cabinet will be flush with the cabinets or built into the wall. This means that you need at least 24 11/16 inches clear in front of the system.

The Dacor Built-in Refrigerators have a similar problem, the refrigerator door is longer than the cabinet is deep. If excess weight is applied on the door, the unit could tip forward. - Page 21 After All’s in Place (continued) The Dacor Built-in Refrigerators include heavy-duty leveling legs at all four corners. These leveling legs are adjusted from the front of the cabinet just as any other service would be performed. Even with new construction there may be slight unevenness to the flooring the system is installed upon.

aCor aCor uilT uilT efrigeraTor efrigeraTor erviCe erviCe anual anual NOTE (CONTINUED) • If you can adjust temperature on one FoodSaver™ assembly but not the other, check the connections to the non-functioning unit. If data is present at the connector, the fault is likely to be in the FoodSaver itself. - Page 44 2 - T eCTion eChniCal rienTaTion Temperature Monitoring (continued) The evaporator thermistor monitors the evaporator temperature and is used in the compressor speed algorithm. A second duty of the evaporator thermistor is termination of the defrost cycle. While there is a safety thermostat available in case of system failure, the end of defrost is determined by the thermistor reading.

Page 45: Variable Capacity Compressor
Variable Capacity Compressor The sealed system in the Dacor Built-in +170VDC Refrigerators incorporate Variable Capacity Cooling. Most conventional refrigeration systems use single speed compressors. The capacity is constant and the controls meet the cooling demand by cycling the compressor on and off. - Page 46 2 - T eCTion eChniCal rienTaTion NOTE • The Variable Capacity Compressor looks very similar to a standard single speed compressor. The three terminals on the outside of the compressor are arranged the same with either style of system. When taking resistance measurements around the terminals on the outside of the case do not let the different motor design cause confusion.
