WARNING Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. The cleaning diagram for the air filter is there for the service person, and not for the customer. NOTE A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner. Caused from its characteristics, a current limit works on the direct current motor. When replacing the highperformance filter or when opening the service board, be sure to stop the fan. [. . . ] . C. Defective fan motor NOTE : However, GND circuit error inside of the motor is rarely detected even if the above check is carried out. When the circuit does not become normal even if P board has been replaced, replace outdoor fan motor. board CN300 CN301 RAV-SP562AT-E, SP802AT-E RAV-SM1103AT-E, SM1403AT-E CDB P board . C.

[. . . ] After then, incorporate front cabinet, upper cabinet, wiring cover, and valve cover as before. Return a set of the refrigeration cycle assembly into the outdoor unit base plate, and assemble sound insulation board, partition plate assembly, fan motor assembly, and side cabinet (R/L) as original. 3-1 Thermostat fixing plate Side cabinet (R) Using screws (Self-tapping screw type-B Ø4 × 8mm, stainless), fix the thermostat fixing plate to the side cabinet (R). 3-2 Do not make cord heater loose. Perform cable process for collected cord heater and fan motor lead cables. After incorporating the inverter assembly as before, furthermore perform cable process for cord heater and power cord. For the cord heater, perform cable process so that there is no looseness or sag at the fan side. [. . . ]
