7-1-2. Outdoor Unit Exhaust fan AVOID: Hot air Heat source heat sources, exhaust fans, etc. (Fig. 4) damp, humid or uneven locations. Outdoor unit choose a place as cool as possible. choose a place that is well ventilated. Fig. 4 allow enough room around the unit for air intake/exhaust and possible maintenance.
7-2. 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 regulations when carrying out the installation. Table 2 lists recommended wire lengths and diameters for power supply systems. NOTE Refer to the wiring system diagram (Fig.
7-3. Remote Control Unit Installation Position The remote control unit can be operated from either a non-fixed position or a wall-mounted position. To ensure that the air conditioner operates correctly, do not install the remote control unit in the following places: In direct sunlight Behind a curtain or other place where it is covered More than 8 m away from the air conditioner...
7-4. How to Test Run the Air Conditioner After turning on the power of the air conditioner, use the remote controller and follow the steps below to conduct the test run. (1) Set the remote controller in Test Run mode. (Fig. 8a) ON/OFF Press and hold the ECONOMY button and the 1HR.
7-5. Removing and Installing the Grille Basically, these models can be installed and wired without removing the grille. If access to any internal part is need- ed, follow the steps as given below. How to remove the grille Open the front panel until it is nearly horizontal, grasp the sections near the front panel arms on both sides, and then remove the panel by pushing the arms towards the outside while pulling the panel towards you.
7-6. Address Setting of the Remote Control Unit The address can be set in order to prevent interfer- ence between remote controllers when 2 indoor units Jumper wire for are installed near each other. To set a different address switching address, it is necessary to change the address on the second remote controller.
8. FUNCTIONS 8-1. Room Temperature Control (1) Cooling Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the indoor unit. NOTE Some informations except for the room temperature are transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.
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. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.
8-3. Freeze Prevention (Cooling and Dry) This function prevents freezing of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil falls below 2 °C for 2 minutes, the control circuit stops the outdoor fan and compressor (The compressor stops 3 seconds after the outdoor fan stopped). During this period, Indoor fan operates in LL.
8-4. Automatic Fan Speed (Cooling and Dry) This automatically adjust the indoor fan speed by the difference between the room temperature and set temperature. < Cooling > Room temp. T+2 °C T+1 °C T °C Set temp. Indoor fan H:High M:Medium L:Low...
9. TROUBLESHOOTING 9-1. Check before and after troubleshooting WARNING Hazardous voltage can cause ELECTRIC SHOCK or DEATH. Disconnect power or turn off circuit breaker before you start checking or servicing. 9-1-1. Check power supply wiring. Check that power supply wires are correctly connected to terminals L and N on the terminal plate in the outdoor unit.
9-2. Air conditioner does not operate. 9-2-1. Circuit breaker trips (or fuse blows). (1) When the circuit breaker is set to ON, it is tripped soon. (Resetting is not possible.) < Failure Cause > There is a possibility of ground fault. There is a possibility of insulation fault.
Page 45
(2) Circuit breaker trips in several minutes after turning the air conditioner on. There is a possibility of short circuit. 1. Check capacity of circuit breaker. Replace with suitable one (larger capacity). 2. Is capacity of circuit breaker suitable ? In case of Heating operation : Measure resistance of outdoor fan Measure resistance of 4-way valve's...
Page 46
(2) Check remote control unit. 1. Try to run with another remote control unit. 2. Is the operation good ? First remote control unit is defective. In the case that the remote control transmission section is dirty, clean it. In the case that the remote control reception section in front of indoor unit is dirty, clean it.
Page 47
9-2-3. Only outdoor unit does not run. (1) Check setting temperature. COOL Is room temperature too low ? 1. Try to lower setting temperature by temperature setting button ( button). 2. Does outdoor unit run ? Check to see if inter-unit wiring is correctly connected between indoor and outdoor unit.
9-3. Some part of air conditioner does not operate. 9-3-1. Only indoor fan does not run. Check fan casing Remove foreign foreign matter on matter or repair. inside. If you turn fan gently once or twice by hand, can the fan turn ? Fan motor winding burnout or foreign Repair or replace.
9-3-4. Only compressor does not run. Is overload relay (OLR) Check compressor motor working ? capacitor. Is temperature of compressor Measure resistance of abnormally high ? compressor motor winding. Does refrigerant gas shortage ? Charge refrigerant gas (R22). Measure Power supply Rotor may be locked up.

Are wide and narrow tubes between Insulate both wide and narrow indoor unit and outdoor unit tubes separately and then insulated ?
10. CHECKING ELECTRICAL COMPONENTS 10-1. Measurement of Insulation Ground wire Resistance Clip The insulation is in good condition if the resistance exceeds 2M ohm. Probe 10-1-1. Power Supply Cord Insulation Clamp the grounding wire of power cord with the lead tester clip of the insulation resistance tester and measure the Fig.
10-2. Checking Continuity of Fuse Fuse on PCB Ass'y Remove the PCB Ass'y from the electrical component box. Then pull out the fuse from the PCB Ass'y. (Fig. 5) Check for continuity using a multimeter as shown in PCB Ass'y Fig.
