Piping Diagrams
Piping diagrams illustrate the refrigerant flow and connections for the air conditioning systems.
Indoor Unit Piping Diagrams
Model: FTXNG09A
Diagram shows the indoor unit's heat exchanger, cross flow fan, and fan motor. It indicates field piping connections (1/4" CuT and 3/8" CuT) to a single union joint, and refrigerant flow for cooling and heating.
Model: FTXNG12A
Similar to FTXNG09A, this diagram shows the indoor unit's heat exchanger, cross flow fan, and fan motor, with field piping connections (1/4" CuT and 3/8" CuT) to a single union joint, and refrigerant flow for cooling and heating.
Model: FTXNG18A
This diagram shows the indoor unit's heat exchanger, distributor, cross flow fan, and fan motor. It indicates field piping connections (1/4" CuT and 1/2" CuT) and refrigerant flow for cooling and heating.
Outdoor Unit Piping Diagrams
Model: RXNG09A
Diagram illustrates the outdoor unit's components including the heat exchanger, compressor, propeller fan, four-way valve, motor operated valve, strainers, and mufflers. It shows field piping connections (3/8" CuT, 5/16" CuT, 1/4" CuT) and refrigerant flow for cooling and heating.
Model: RXNG12A
This diagram shows the outdoor unit's heat exchanger, compressor, propeller fan, four-way valve, motor operated valve, strainers, and mufflers. It indicates field piping connections (3/8" CuT, 5/16" CuT, 1/4" CuT) and refrigerant flow for cooling and heating.
Model: RXNG18A
This diagram shows the outdoor unit's heat exchanger, compressor, propeller fan, four-way valve, electronic expansion valve, strainers, and mufflers. It indicates field piping connections (1/2" CuT, 3/8" CuT, 1/4" CuT) and refrigerant flow for cooling and heating.
Capacity Tables
The following tables provide detailed capacity information (Total Capacity - TC, Sensible Heat Capacity - SHC, Power Input - PI) for various operating conditions.
Capacity Data for FTXNG09A - RXNG09A
Tables show Cooling and Heating capacities based on Indoor and Outdoor temperatures (°C and °F). Units for TC/SHC are kBtu/h or kW, and PI is in kW.
Capacity Data for FTXNG12A - RXNG12A
Tables show Cooling and Heating capacities based on Indoor and Outdoor temperatures (°C and °F). Units for TC/SHC are kBtu/h or kW, and PI is in kW.
Capacity Data for FTXNG18A - RXNG18A
Tables show Cooling and Heating capacities based on Indoor and Outdoor temperatures (°C and °F). Units for TC/SHC are kBtu/h or kW, and PI is in kW.
Capacity Correction Factor by Length of Refrigerant Piping
Graphs illustrate the capacity correction factor as a function of refrigerant piping length (in meters and feet) for both cooling and heating operations for different model series (FTXNG09A/RXNG09A, FTXNG12A/RXNG12A, and FTXNG18A/RXNG18A). The graphs show that the correction factor decreases as piping length increases. Notes explain that the correction ratio is the same for different installation heights and that capacity is calculated as engineering data multiplied by the capacity correction factor. The actual unit piping length must not exceed the maximum shown.
Operation Limit
Graphs display the operational limits for the air conditioning units based on indoor and outdoor temperatures.
Cooling Operation Limits:
The graph plots Outdoor Temperature (°FDB) against Indoor Temperature (°FWB). It defines regions for "Continuous operation" and "Pull-down period". For example, continuous operation is possible within a range of approximately 50°F to 86°F outdoor temperature and 50°F to 86°F indoor wet-bulb temperature.
Heating Operation Limits:
The graph plots Outdoor Temperature (°FWB) against Indoor Temperature (°FDB). It indicates the range for "Continuous operation". For example, continuous operation is possible from approximately 14°F to 86°F outdoor wet-bulb temperature and 50°F to 86°F indoor dry-bulb temperature.
Sound Level
Measuring Location
A diagram shows the standard measuring location for sound level tests: 1.0 meter horizontally and 0.8 meters vertically from the unit, in an anechoic chamber.
Sound Pressure Level
Tables provide the 1/1 Octave A-weighted Sound Pressure Level (dB, ref 20µPa) for different models (FTXNG09A, FTXNG12A, FTXNG18A) at various speeds (High, Med, Low, Quiet) for both Cooling and Heating modes. The data includes levels for different frequency bands (63Hz to 8kHz) and an Overall Noise level (dBA).
NC Curve
NC (Noise Criteria) curves are presented graphically, plotting Octave Band Sound Pressure Level (dB) against Octave Band Center Frequency (Hz). The curves represent different noise criteria levels (NC-20 to NC-70) and show how the sound output of the units at different speeds (Quiet, Low, Medium, High, Turbo) compares to these criteria. The note clarifies that SILENT (SL) is equivalent to QUIET (Q).

Symbols:
- MCA: Minimum Circuit Amps (A)
- MOP: Maximum Overcurrent Protection (A)
- COMP: Compressor
- RHz: Rated Operating Frequency (Hz)
- A: Compressor Input Current (A)
- OFM: Outdoor Fan Motor

Notes:
- RHz is the max frequency that occurs in cooling and heating operation.
- RLA is the max current that occurs in cooling and heating operation.
- Maximum allowable voltage unbalance between phases is 2%.
- Select wire size based on the larger value of MCA.
- Use circuit breaker instead of fuse.
