R When a status TE > 20°C is detected continuously for 5 minutes, the operation may stop. This TE [°C] status does not output an error code and is assumed as usual status of thermo-OFF. 2 minutes 30 seconds and 24 this intermittent operation is not a trouble.

Coil heating control 1) This control function heats the compressor by turning on the stopped compressor instead of a case heater. It purposes to prevent slackness of the refrigerant inside of the compressor. The defrost operation is also finished when defrost operation has continued for 10 minutes even if TE sensor temperature has become 7°C or lower. S After defrost operation has finished, the compressor and the outdoor fan start heating operation after stopped for approx.

Before troubleshooting 1) Required tools/instruments · + and ­ screwdrivers, spanners, radio cutting pliers, nippers, push pins for reset switch · Tester, thermometer, pressure gauge, etc. 2) Confirmation points before check Q The following operations are normal. · Is not outside high-temperature operation controlled in heating operation?· Does not cool air discharge preventive control work in heating operation?· Does not high-temperature release operation control work in heating operation? [. . . ] When there is the heating part near the electric parts box, a fire may generate. Be sure to set the heating part on the outdoor unit base at the fan room side or near it. (within 20cm from the outdoor unit base) Heating part Enlarged marked part 2-1 2-2 * Be careful that the cord heater does not hit the fan. Fix the cord heater without any loosening or sag As shown in the left figure, drill a hole on the back cabinet for fixing the thermostat fixing plate. [. . . ]
