CORRECTION FACTORS FOR INTERCONNECTING PIPE WORK MO35-65
Remarks: 1. H is the Height difference of the outdoor unit above the indoor unit.
2. If indoor is installed above outdoor, please use 0.97 to multiply the result from the table above.
3. Piping length is in equivalent pipe length in meters.
For calculation of equivalent meters from measured pipe length, refer to piping applications information.

The following chart can be used as a guide and are based on the assumption that the piping installed will not exceed 20kPa
pressure drop for suction or liquid line. The capacity given for the standard may be multiplied by the factor given below to pr
ovide
the de-rated capacity.
