NOTE

• If the LOW fan speed is selected and the outdoor temperature is higher than 21°C, the compressor is subjected to an excessive load when operating in heating mode.
• Therefore, the fan speed should be set to HIGH or MEDIUM to avoid activating the safety devices.
• When the system is restarted after a shutdown of more than approximately 3 months, the system should be checked by your service provider.
• Turn off the main switch when the system is to be inoperative for a long period of time. Otherwise, the system consumes electricity as the oil heater remains active even though the compressor is stopped.

OPERATION PROCEDURE FOR COOLING, HEATING, DRY, AND FAN OPERATIONS

� Before operation: –     Turn on the electrical power supply to the system approximately 12 hours before start-up after a long shutdown. Do not start the system immediately after connecting the power supply, because the compressor may be damaged if it is not sufficiently heated. –     Make sure the outdoor unit is not covered with ice or snow. If it is, remove the ice or snow with warm water (no hotter than 50°C). –     If the water temperature is over 50°C, the plastic parts may be damaged.
1.  Turn on the power supply. Three vertical lines will appear on the liquid crystal display, with the indication A/C or VENTI. 2.  Press the MODE switch. By repeatedly pressing the MODE switch, the indication changes from COOL, through HEAT, DRY to FAN, in that order (in the case of cooling-only models, COOL, DRY and FAN). (The figure shows when the “COOL” mode setting is selected).
3. Press the RUN/STOP switch. The RUN indicator (red) lights up. The system starts automatically.     NOTE: Setting temperature, fan speed and air louver direction. The setting is memorized after the irst time and does not require resetting every day. When the setting needs to be changed, refer to the section “Setting the Temperature, Fan Speed and Air Louver Direction”.
4. Switch OFF (STOP) Press the RUN/STOP switch again. The RUN indicator (red) is OFF. The system is automatically stopped.     NOTE: The fan may continue operating for approximately 2 minutes after the heating operation is stopped.

SETTING THE TEMPERATURE, FAN SPEED, AND AIR LOUVER DIRECTION

� DO NOT touch the OK switch. –     The OK switch is used only for servicing. –     If the OK switch is pressed by mistake and the mode is changed from operation to check mode, press the OK switch again for approximately 3 seconds, wait 10 seconds and then press again. –     The mode will change back to normal.
� Setting the temperature –     Set the temperature by pressing the TEMP (0) or 19 switch. –     The temperature increases 1°C when the (0) switch is pressed (max 30°C). –     The temperature decreases 1°C when the 19 switch is pressed (min. 19°C for COOL, DRY and FAN modes; min. 17°C for HEAT mode). (The figure shows the temperature set to 28°C).
� Setting Fan Speed –     Press the FAN SPEED switch. –     When the FAN SPEED switch is pressed repeatedly, the indication changes from HIGH to MEDIUM to LOW, in that order. –     For normal operation, set the fan speed to HIGH. (The figure shows the fan speed set to MED.)   NOTE: In the DRY mode, the fan speed automatically changes to LOW, and cannot be altered (however, the indication shows the current setting).
� Setting the swing louver direction Press the SWING LOUVER switch: the louver begins to swing. Pressing the switch again fixes the position of the swing louver. Pressing the switch repeatedly stops and swings the louver successively. � Fixed position The indication shows the air flow direction. � Automatic swing position The indications move continuously corresponding to the louver swing.     NOTE: In the heating operation, the louver angle changes automatically.

OPERATION PROCEDURE FOR VENTILATION

This function is available only when the total heat exchanger is connected. If the procedures below are performed when the total heat exchanger is not connected, the NO FUNCTION indication blinks for 5 seconds.

�          Ventilation Press the VENTI switch By repeatedly pressing the VENTI switch, the indication changes from A/C through VENTI and A/C+VENTI, in that order. (The figure shows the A/C + VENTI setting). NOTE: Contact your distributor or HITACHI dealer for detailed information. If the mode is changed to VENTI during individual operation of the air conditioner, the air conditioner will stop. If the mode is changed to A/C during individual operation of the total heat exchanger, the total heat exchanger will stop.

OPERATION PROCEDURE FOR AUTOMATIC COOLING/HEATING OPERATION

The automatic cooling/heating operation must be set using the optional function. Contact your distributor or HITACHI dealer for more detailed information. This function enables the operation mode (cooling or heating) to be changed automatically according to the temperature difference between the set temperature and the suction air temperature. If the suction air temperature exceeds the set temperature by 3°, the operation changes to COOL mode. If it is 3°C lower than the set temperature, the operation changes to HEAT mode.
NOTE:
If the heating operation is set at the LOW fan speed, the protective devices will often cause the system to stop. In this case, set the fan speed to HIGH or MED. If the outside temperature is over approximately 21°C, the heating operation is not available. The temperature difference between the cooling and heating operations is quite considerable when this function is used. This function cannot, therefore, be used for air conditioning in a room where accurate control of temperature and humidity is required.

PROCEDURE FOR SETTING THE SWING LOUVER

Setting the swing louver	1. When the SWING LOUVER switch is pressed, the swing louver starts its horizontal to vertical position. When the “…“ symbol is moving, this operation. The range of the angle of the swing is approximately 70° from indicating the continuous operation of the louver. 2. When the swinging operation of the louver is not required, press the SWING direction of the  symbol. LOUVER switch again. The louver stops at the angle indicated by the   3. The discharge air angle is fixed at 20° for the RCI series and 40° for RCD series during the start-up of the heating and defrosting operation when the thermostat is on. When the outlet air. temperature exceeds approximately 30 C, the louvers start to swing.
Fixing the louver	1. For COOL and DRY modes, the discharge air angle can be changed to 5 different positions. For the heating operation, it can be changed to 7 positions. 2. To fix the louver position, first press the SWING LOUVER switch to start the louver swinging, and then press again when the louver reaches the required position. 3. The discharge air angle is fixed at 20° for the RCI series and 40° for the RCD series during the start-up of the heating and defrosting operation when the thermostat is on. When the outlet air temperature exceeds approximately 30 °C, the louvers start to swing.     When the louvers are fixed at an angle of 55° for RCI, 65° for RCD or 70° for both during the heating operation and the operation mode is changed to cooling, the louvers will be automatically fixed at an angle of 45° for RCI or 60° for RCD.     NOTE: There is a time lag between the actual angle of the louver and the indication on the liquid crystal display. When the SWING LOUVER switch is pressed, the louver will not stop immediately. The louver will move one extra swing. If the louvers are moved when cleaning or for any other reason, select the auto-setting mode to move the four louvers to the same position.

Do not turn the air louver by hand. The louver mechanism may be damaged if moved (in all units).
�          Wall-mounted type (RPK): Adjust the vertical louvers by hand to discharge air in the required direction. Do not swing blade 1 to the left and blade 2 to the right of the vertical louvering. �          Automatic setting of the louver: When the unit is not in operation, two air louvers stop automatically in the closed position.
�          Ceiling-mounted type (RPC): The vertical louver consists of four sets of louvers. Adjust the vertical louvers by hand to discharge air in the required direction.   NOTE: The models which do not have a swing louver will not show the above indications on the remote control. In this case, the louver must be adjusted manually.
