[. . . ] If an above action is executed during the fan operation, the protective control works to stop the unit operation, and the check code "P12" may be issued. When the desired operation has finished, be sure to reset the system to clear "P12" error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

Improve and delete the cause Replace TD sensor. Check CDB. Defect Replace * For RAV-SM562AT-E, replace control P. C. board. ® [H01 error] Is power voltage normal?YES NO Improve power line. YES Is not abnormal overload?NO Is the circuit detected by current sensor normal?YES NO Improve and delete the cause. Check and correct circuit cables. Check IPDU. Defect Replace * For RAV-SM562AT-E, replace control P.

Check TE sensor. If [E03] occurs during an operation, the air conditioner stops. [F29 error] / [12 error] [F29 error] or [12 error] indicates detection of trouble which occurred on IC10 non-volatile memory (EEPROM) on the indoor unit P board during operation of the air conditioner. . C. * If EEPROM has not been inserted when the power was turned on or if EEPROM data never be read/written, the automatic address mode is repeated. In this time, the central controller displays [97 error]. (Power ON) (Approx. 3 minutes) [SET] is displayed on main remote controller. (Repetition) LED (D02) on indoor unit P. C. 10 seconds. Reboot (Reset) [P31 error] (Sub indoor unit) When the master unit of a group operation has detected [E03], [L03], [L07], or [L08] error, the sub unit of the group operation detects [P31 error] and then it stops. There is no display of the check code or alarm history of the main remote controller. (In this model, the mode enters in automatic address set mode when the master unit has detected [E03], [L03], [L07], or [L08] error. ) ­ 99 ­ 10-4-2.

[. . . ] When the power cord size does not match with Pshape clamp, procure the most appropriate one at the local site. ­ 190 ­ No. Assembly 3 Photo / Explanatory diagram Procedure Return a set of the refrigeration cycle assembly into the outdoor unit base plate and reassemble sound insulation board, partition plate assembly, fan motor assembly, and side cabinet (R/L) as original. Fix the thermostat fixing plate to the side cabinet (R), built in the inverter assembly, and then connect various cables. After then, incorporate front cabinet, upper cabinet, wiring cover, and valve cover as before. [. . . ]
