12.3 Insufficient cooling performance when a long piping is applied
Question and answer for the field work
Example 2: Insufficient cooling performance when a long piping is applied
Phenomenon Sufficient cooling was not available for an indoor unit that was located at the farthest position.
Cause
If the location of an outdoor unit is 20 meters lower than the location of the indoor units, resetting of the DIP switch DSW3
is required.
However, no setting was performed. Therefore, the largest discharge pressure was not increased. This resulted in an
insufficient cooling performance for the indoor unit.
Countermeasure The setting of the DSW2 was changed.
Remarks Pay special attention to the size of liquid pipe. Refer to "piping work in TC" for details.
