Typically ranges between 10A to 14A depending on voltage.

R134a (most common for this series) or R600a. Always check the chassis label before charging.

Charging must be done with the precise calculated charge of . The charging cylinder should be placed on a scale, and the exact weight should be added. Because R290 is flammable, all work must be done in a well-ventilated area away from any sources of ignition. A leak check must be performed after charging.

Classified as a unit, the L68WU1 is engineered to maintain low suction pressures. It handles evaporating temperatures dropping well below -20°C (-4°F), making it an optimal match for deep freezers, commercial ice makers, and ice cream display boxes. Electrical Component Architecture

Correct installation is critical for the safety and longevity of the L68WU1.

Built with a highly robust , the compressor features a specialized internal oil lubrication style that minimizes friction, reduces thermal stress, and mitigates operational noise in commercial environments. Appliance Compatibility and Applications R134a (most common for this series) or R600a
