Rated Frequency Operation

11 Servicing Information

11.1. Troubleshooting

During troubleshooting and servicing, rated compressor operating frequency must be obtained in order to check the
specification and technical data. Below are the methods used to obtain rated compressor operating specification.

(a) Cooling

(i) Press the Auto button continuously for 5 seconds or less than 8 seconds, the air conditioner starts operation at Cooling rated frequency.

(“beep” will be heard at the 5th second.)

(ii) Short the service terminal (CN-S) of the outdoor printed circuit board. The air conditioner starts operation at Cooling rated frequency.

(b) Heating

Press the Auto button continuously for 8 seconds or less than 11 seconds, the air conditioner starts operation at Heating rated
frequency. (“beep” “beep” will be heard at the 8th second.)
