INTRODUCTION Three generations of pride and quality manufacturing and design improvements are built into all U-Line products. The result: U-Line leads the market with innovative technology and superior craftsmanship. This manual contains specific instructions for servicing the U-Line Échelon 2075DWRR, CO2075DWR and 2075DWRWC. Potential Problems W [...]

SERIAL NUMBER FORMA T The serial number is divided into four segments. A typical serial number is 031234-01-5678. The first two digits of the first segment, 03, represent the year the unit was made. The next four digits, 1234, represent the shop order number . Every model is assigned a new shop order number at the beginning of a production run. The[...]
