If you do not want to use this function, Signal transmitting section please consult the service representative because the setting of the unit needs to be changed. Auto restart function is Use this operation when you want to be comfortable in COOL mode even with energy saved. Before starting maintenance Cleaning the indoor unit The panel may come off in order to prevent it from being damaged. Turn off the breaker. Clean the unit using a soft dry cloth. Cleaning the air cleaning filter about once every 3 months Air cleaning filter replacement About once every year Remove the air filter.

Page 9 Page 10 How to operate with fixed operational frequency of the compressor. Page 11 Condensing pressure How to operate with fixed operational frequency of the compressor.
Cooling Air flow should be set to High speed. Heating Air flow should be set to High speed. Page Standard Operation Data Page 14 Since operating conditions vary according to the areas where these units are installed. The following information has been provided to clarify the operating characteristics of the system under the conditions indicated by the performance curve. Page 16 Cooling capacity These values are under rated frequency. These values are under rated frequency. Indoor unit receives the signal with a beep tone.
When the system turns off, 3-minute time delay will operate to protect system from overload and compressor will not restart for 3 minutes. Page 24 Page 26 Compressor and Outdoor fan motor continuously at set speed Indoor fan motor The compressor and the indoor fan are controlled by the temperature. By such controls, amount of air flow of indoor unit will be reduced in order to lower humidity without much room tempera- ture drop. Page 28 3 Warm air control. When any condition of 1 a.
Hz MAX. Page 30 6. Page 31 Comparing the current rotational frequency with the target rotational frequency High, Med. When any of the following conditions occurs in HEAT operation, the horizontal vane angle changes to Angle 1 automati- cally to prevent cold air blowing on users.
Page 33 Emergency operation is available when the remote controller is missing, has failed or the batteries of remote controller run down. Page 34 2 At normal operation Alternating current supplied from power supply is eliminated of any noise by L62 Common mode choke coil and L63 Common mode choke coil.
Then DS61 Diode stack performs full-wave rectification of alternating current and the alternating current is converted to direct current. C63 Smoothing capacitor stabilizes the power supply converted to direct current from alternating current and supplies it to IPM Intelligent power module.
Page 35 Operational frequency control of outdoor unit 1. Outline The operational frequency is as following: First, the target operational frequency is set based on the difference between the room temperature and the set temper- ature. Page 36 3. As a result, the frequency and LEV are controlled as shown the table below. Page 37 Refer to page Page 40 When the main power is turned off and then turned back on, the unit restarts automatically in the memorized set conditions approximately after 3 minutes.
Cautions on troubleshooting 1. Before troubleshooting, check the following: 1 Check the power supply voltage. Take care the following during servicing. Page 42 Troubleshooting procedure The following procedure facilitates identifying defective points. Page 43 1. The location of LED is illustrated at the right figure.
LED lights up during normal operation. Page 45 2. Trouble criterion of main parts Part name Check method and criterion Figure Room temperature Measure the resistance with a tester.
