Also, there is a need to limit line length for the best oil return results to insure maximum lubracation of the compressor's internal parts.

• Q 02 . Is there a minimum length requirment for linesets connecting LG ductless systems?

  Answer : Field investegations of actual equipment have demonstrated the fact that LG ductless systems have worked to customer satisfaction with line lengths as short as 8 feet. Acceptability depends on the application and climate at the point of installation. For example: on residencial applications the customer may complain of off cycle refrigerant noises on installations with line
