Refrigerant Additional Charge
The unit has been filled with refrigerant, but if L (total pipe length) exceeds standard length, additional refrigerant (R410A) change is
required.
For 24K: Additional refrigerant charge=[L-74-4/5(22.8m) ]× 0.807oz/5ft (15g/m)
For 36K: Additional refrigerant charge=[L-98-3/7(30m) ]× 0.807oz/5ft (15g/m)

When the indoor unit is lower than the outdoor unit, and the height
is larger than 16 feet, an oil bend should be employed for every 16 feet.
NOTE:
1. To avoid storing too much oil in the oil bend, the oil bend should be as short as possible.
2. The horizontal piping should be sloped down along the refrigerant flow direction, to bring the oil back to compressor. The slope
should be between 1/200 and 1/250.
In order to ensure cooling/ heating performance better, the refrigerant piping should be as short and straight as possible.
