*Be sure to add the proper amount of additional refrigerant. Failure to do so may result in reduced performance.
Remark: The refrigerant pre-charged in the outdoor unit is for piping length up to 7.5m.
Allowable Piping Length
If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to
the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Always choose the shortest path and follow the recommendations as tabulated below:
REFRIGERANT PIPING
Model
Indoor (FTXK) 25 35 50 60
Outdoor (RXK) 25 35 50 60
Min. Allowable Length (L), m 33
Max. Allowable Length (L), m 20 30
Max. Allowable Elevation (E), m 10 10
Gas Pipe Size, mm/(in) 9.52 (3/8") 12.70 (1/2") 15.88 (5/8")
Liquid Pipe Size, mm/(in) 6.35 (1/4") 6.35 (1/4")
Equivalent length for various fitting (meter)
Pipe Size L joint Trap bend
3/8" (OD9.52mm) 0.18 1.3
1/2" (OD12.7mm) 0.20 1.5
5/8" (OD15.9mm) 0.25 2
3/4" (OD19.1mm) 0.35 2.4
7/8" (OD22.2mm) 0.40 3
1" (OD25.4mm) 0.45 3.4
1 1/8" (OD28.6mm) 0.50 3.7
1 3/8" (OD34.9mm) 0.60 4.4
Notes:
1. Equivalent piping length is obtained with actual length of gas piping.
2. 90° bend of piping is equivalent to L joint.

Bending must be carefully made so as not to crush the pipe. Use a pipe bender to bend a pipe where possible.
