8 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.

INSTALLATION MANUAL
4.1.1. 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 sufÞ ciently 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.
9CAUTION
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 Þ gure shows when the “COOL” mode setting is selected).
3. Press the RUN/STOP switch.
The RUN indicator (red) lights up. The system starts automatically.
8
NOTE:
Setting temperature, fan speed and air louver direction.
The setting is memorized after the Þ rst 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.
8
NOTE:
The fan may continue operating for approximately 2 minutes after the heating operation is stopped.
4.1.2 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.
:ATTENTION
Setting the temperature
Set the temperature by pressing the TEMP ; or < switch.
The temperature increases 1°C when the ; switch is pressed (max 30°C).
The temperature decreases 1°C when the < switch is pressed (min. 19°C for COOL, DRY and FAN modes; min. 17°C for HEAT
mode). (The Þ gure 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 Þ gure shows the fan speed set to MED.)
8 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 Þ xes the position of the swing louver.
Pressing the switch repeatedly stops and swings the louver successively.
Fixed position
The indication shows the air ß ow direction.
Automatic swing position
The indications move continuously corresponding to the louver swing.
8
NOTE:
In the heating operation, the louver angle changes automatically.
4.1.3. 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.
:ATTENTION
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 Þ gure shows the A/C + VENTI setting).
8
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.

INSTALLATION MANUAL
4.1.4. 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.
8
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 a room where accurate control of temperature and humidity is required.
4.1.5. PROCEDURE FOR SETTING THE SWING LOUVER
Setting the swing louver
1. When the SWING LOUVER switch is pressed, the swing louver starts its
operation. The range of the angle of swing is approximately 70° from the
horizontal to the vertical position. When the “=“ symbol is moving, this
indicates the continuous operation of the louver.
2. When the swinging operation of the louver is not required, press the SWING
LOUVER switch again. The louver stops at the angle indicated by the
direction of the “=“ symbol.
3. The discharge air angle is Þ xed 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 Þ x the louver position, Þ rst 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 Þ xed 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 Þ xed 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 Þ xed at an angle of
45° for RCI or 60° for RCD.
8 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.

4.1.8. INDICATIONS UNDER ABNORMAL CONDITIONS
Disfunction
The RUN indicator (red) blinks.
The ALARM indicator appears on the liquid crystal display.
The indoor unit number, the alarm code and the model code are indicated on the liquid crystal display. If
several indoor units are connected, the above items are indicated one by one for each of them.
Make a note of the indications and contact your HITACHI service provider.
Power failure
All the indications disappear.
If the unit stops because of a power failure, it will not restart even when the power returns. Perform the
start-up operations again.
If the power failure lasts less than 2 seconds, the unit will automatically start up again.
Electrical noise
The indications may all be OFF and the unit stopped. This is because the microcomputer has been
activated in order to protect the unit from electrical noise.
8 NOTE:
If the wireless remote control switch is used for the wall-mounted indoor unit, remove the connectors
(CN25) connected to the indoor PCB. If they are not removed, the unit will not operate.
The memorized data can not be erased unless the remote control switch is initialized.
