Application Information
Outdoor Clearance
If the condensing unit is operated in an atmosphere containing oils (including machine
oils), salt (coastal area), sulphide gas (near hot spring, oil renery plant), such as
substances may lead to failure of the unit.
• Where a wall or order obstacle is in the path of outdoor unit’s intake or exhaust airow, follow the
installation guidelines below.
• For any of the below installation patterns, the wall height on the exhaust side should be 1200mm or less.

Refrigerant Piping
Piping Length and Elevation
When the pipe length becomes too long, both the capacity and reliability drop.As the number of bends increases,
system piping resistance to the refrigerant ow increases, thus lowering the cooling capacity, and as the result
the compressor may become defective. Always choose the shortest path and follow the recommendation as
tabulated below:

Outdoor Unit

Liquid Pipe Size, mm/(in) 6.35 (1/4") 6.35 (1/4")
Additional Charge
• The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.5m, additional charge of the
refrigerant after vacuuming is not necessary.
• When the piping length is more than 7.5m, additional refrigerant charge (g) per additional 1m length as
tabulated:
Model FTXS25A FTXS35A FTXS50A FTXS60A
RXN25F RXN35F RXN50C RXN60C
Additional charge [g/m] 20
Example:
FTXS25 & RXN25 with 12m piping length, additional piping length is 4.5m.
Thus, Additional charge = 4.5[m] x 20[g/m]
= 90.0[g]

Calculation Steps
Interpolation method can be used to get the total
cooling capacity, TC and sensible cooling capacity,
SC and power input, PI at those temperatures which
are not stated out in the table. Extrapolation method
is not allowed to be used.
Example:
Indoor Condition: 25°C DB, 17°C WB
Outdoor Condition: 37°C DB
Fan Speed: High
Solution:
Based on the Performance Table,
1. Refer to the Indoor DB column,
- 25°C is located between 24°C & 27°C
for 16°C WB.
- 25°C is located between 24°C & 27°C
for 19°C WB.
- Thus, Interpolation needs to be applied.
2. Refer to the Indoor WB column,
- 17°C is located between 16°C & 19°C
for 25°C DB.
- Thus, Interpolation needs to be applied.
3. Refer to the Outdoor DB column,
- 37°C is located between 35°C & 40°C.
- Thus, Interpolation needs to be applied.
