Indoor Unit Capacity
Use the above tables to determine the capacities of indoor units to be connected. Make sure the
total capacity of indoor units connected to each outdoor unit is within the specified value (Btu/h).
The total capacity of connected indoor units must be within a range of 70 to 130% of the rated
capacity of the outdoor unit.
In some models, it is not possible to connect the maximum number of connectable indoor units.
Select models so the total capacity of connected indoor units conforms to the specification.

- Check no 12 check on pulse input of position signal of fan inverter pcb 1 disconnect the connector x2a while power supply off and operation off 2 is the voltage between pins no 4 and 5 on x2a approx 15 v after power supply is turned on 3 connect the connector x2a while power supply off and operation off 4 check below conditions when the fan motor is rotated one turn manually under the condition of operation off after power supply is turned on are the pulse approx 0 v and 5 v generated 4 times between no 1 and 5 on x2a are the pulse approx 0 v and 5 v generated 4 times between no 2 and 5 on x2a are the pulse approx 0 v and 5 v generated 4 times between no 3 and 5 on x2a 226
- Check no 13 power transistor check mode when the inverter system malfunctions malfunction of inverter inv compressor to locate where the malfunction occurs switching to the power transistor check mode of inverter in the service mode setting enables not to judge the position detection signal malfunction but to output waveform only during inverter operation the waveform can be checked by disconnecting the wiring of compressor after the completion of checks return the system to the previous mode and wait for 30 seconds or more until the discharge of capacitor is completed then conduct a subsequent work 226
- Notes be sure to disconnect the compressor wiring when conducting the check operation mentioned above when the output voltage is approx 100 200 v 10 hz and the voltage balance between phases u v v w w u is within 5 the inverter pcb is normal 226

- About refrigerant r 410a 257
- Characteristics of new refrigerant r 410a 1 performance almost the same performance as r 22 and r 407c 2 pressure working pressure is approx 1 times more than r 22 and r 407c 3 refrigerant composition few problems in composition control since it is a quasi azeotropic mixture refrigerant 257
- Mpa 145 psi 257
- Non azeotropic mixture refrigerant mixture of two or more refrigerants having different boiling points 257
- Outline 257
- Precautions for new refrigerant r 410a 257
- Quasi azeotropic mixture refrigerant mixture of two or more refrigerants having similar boiling points 257
- The design pressure is different at each product please refer to the installation manual for each product reference 1 mpa 10 9716 kgf c 257

- As for the charge mouthpiece and packing 1 2unf20 is necessary for mouthpiece size of charge hose 259
- Copper tube material and thickness 259
- O soft annealed h hard drawn 259
- R 410a is used under higher working pressure compared to previous refrigerants r 22 r 407c furthermore the refrigerating machine oil has been changed from suniso oil to ether oil and if oil mixing is occurred sludge results in the refrigerants and causes other problems therefore gauge manifolds and charge hoses that are used with a previous refrigerant r 22 r 407c can not be used for products that use new refrigerants be sure to use dedicated tools and devices 259
- Service tools 259
- Tool compatibility 259
- Conventional flaring tools can be used when the work process is changed change of work process previously a pipe extension margin of 0 to 0 mm was provided for flaring for r 410a air conditioners perform pipe flaring with a pipe extension margin of 1 to 1 mm for clutch type only conventional tool with pipe extension margin adjustment can be used 260
