43 Fig. 5b 7-1-2. Outdoor Unit AVOID: ● heat sources, exhaust fans, etc. (Fig. 4) ● damp, humid or uneven locations. DO: ● choose a place as cool as possible. ● choose a place that is well ventilated. ● allow enough room around the unit for air intake/ exhaust and possible maintenance.
44 7-2. Remote Control Unit Installation P osition The remote control unit can be operated from either a non-fixed position or a wall-mounted position.
45 7-3. Address Switc hes If you are installing more than 1 indoor unit (up to 2) in the same room, it is necessary for you to assign each unit its own address so each can be operated by its own remote control unit. You assign the addresses by matching the switch positions of each indoor unit with the switch positions of its remote control unit.
46 7-4. Recommended Wire Length and Diameter Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these reg- ulations when carrying out the installation.
47 8. FUNCTION 8-1. Room T emperature Control ■ Cooling ● Room temperature control is obtained by cycling the compressor ON and OFF under control of the room tem- perature sensor in the remote control unit.
48 ■ Heating ● Room temperature control is obtained by cycling the compressor ON and OFF under control of the room tem- perature sensor in the remote control unit. ● The room temperature (and other information) is transmitted every 3 minutes by the remote control unit to the controller in the indoor unit.
49 8-2. Dry Operation (Dehumidification) ● Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature.
50 8-4. Freeze Prevention (Cooling) ● This function prevents freezing of the indoor heat exchange coil. ● When the compressor has been running for 10 minutes or more and the temperature of the indoor heat exchange coil falls below 30°F, the control circuit stops the compressor for at least 6 minutes.
51 8-6. Cold draft Prevention (Heating) ● This function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat exchange coil have sufficiently warmed up. ● STANDBY lamp on front of the indoor unit lights up when this function is working.
52 8-7. Defr osting Operation (Heating) ■ Defrosting Flowchart Compressor ON Indoor heat exchanger coil temperature drops 1.4 ¡ F per 6 minutes and it repeats 3 times in succession. Integrated operating time of compressor is more than 3 hours. Defrosting begins.
53 ■ Defrosting Mode Timing Chart *1: Refer to "8-6 Cold Draft Prevention". 8-8. Low T emperature Cutff (Heating) ● This function protect the compressor from being damaged due to flow back of the liquid refrigerant to the com- pressor when the outdoor temperature is very low.
54 9. TR OUBLESHOO TING 9-1. Chec k before and after tr oubleshooting 9-1-1. Check po wer supply wiring. ● Check that power supply wires are correctly connected to terminals No. 7 (L1) and No. 8 (L2) on the terminal plate in the outdoor unit. 9-1-2.
55 9-2. Air conditioner does not operate . 9-2-1. Circuit breaker trips (or fuse b lows). A. When the circuit breaker is set to ON, it is tripped soon. (Resetting is not possible.) ● There is a possibility of ground fault. ● Check insulation resistance.
56 B. Circuit breaker trips in several minutes after turning the air conditioner on. ● There is a possibility of short circuit. 9-2-2. Neither indoor nor outdoor unit runs. A. Power is not supplied. B. Check "OPERATION selector" switch in the indoor unit.

62 9-4-2. P oor cooling or heating. 9-4-3. Excessive cooling or heating. NO NO • Set temperature is suitable. Set temperature to higher or lower value using temperature setting buttons of the remote control unit. • Remote control unit is placed where it can detect room temperature properly.
63 9-5. If a sensor is defective. 9-5-1. Indoor coil temp. thermistor (TH1) is defective . A. Open When thermistor opens, the air conditioner will be in the following conditions as the controller tries to detect extremely low indoor coil temperature. In Cooling mode: Function of freeze prevention continues to work.
