• Remote control holder

• Screws for remote control holder x 2

Follow these steps to insert the batteries:

1. Pull out the back cover of the remote control.

2. Insert AAA or R03 batteries.

3. Close the cover.

To set the clock on your remote, follow these steps:

1. Press CLOCK, then press the arrow buttons to set the time.

2. Press SET to confirm.

To switch between 12-hour (am/pm) and 24-hour format, press and hold the CLOCK button for approximately 5 seconds.

To start or stop the PANASONIC CS-Z9AKUAW:

1. Press OFF/ON to start or stop the operation. When the unit is ON, “OFF” disappears from the remote control display.

2. Press MODE to select the desired mode (AUTO, HEAT, FAN, DRY, COOL).

3. Press TEMP UP or TEMP DOWN to select the desired temperature.

The temperature selection range is 60 °F to 86 °F (16.0 °C to 30.0 °C). To switch the display between °F and °C, press and hold the down arrow button in the timer section for approximately 10 seconds.

You can adjust the airflow direction on your PANASONIC CS-Z9AKUAW using the remote control:

• Press the AIR SWING button to adjust the upper/lower direction (swinging motion).

• Press the AIR SWING button with the lateral arrows to adjust the lateral direction (swinging motion).

Note: Do not adjust the flap by hand.

To adjust the fan speed:

• Press the FAN SPEED/QUIET button to cycle through the options.

• When FAN AUTO is selected, the fan speed is adjusted automatically according to the operation mode.

• Select the lowest fan speed setting for low noise operation.

To use QUIET mode:

• This operation reduces airflow noise. For multi-split systems, Quiet mode only activates when the button is pressed for all indoor units that are switched ON.

To reach the desired temperature quickly, use the POWERFUL mode. Press the POWERFUL button to activate it. This operation will continue until it is cancelled. To cancel, press the POWERFUL button again or turn the unit off.

To reduce power consumption for better energy saving without sacrificing comfort, press the ECO button. To cancel, press the ECO button again. This operation cannot be used in FAN mode.

The Room Freeze Protection (RFP) function is used in unoccupied spaces during the winter to protect equipment from freezing temperatures. To use it, press the RFP button.

When selected, the unit operates in Heat mode with high fan speed. When the room temperature drops below the set temperature (50 °F or 46 °F), the compressor starts. When the temperature is reached, the compressor stops. This cycle repeats continuously. This feature is not applicable if the unit is connected to a multi-split outdoor unit.

To cancel this operation, press the MODE button.

You can set the timer to turn the unit on and off at 2 different preset times. Follow these steps:

1. Select TIMER ON or TIMER OFF. Each time you press the button, it will cycle through the timer options.

2. Set the time using the arrow buttons.

3. Confirm the setting by pressing SET.

To cancel a timer, select the respective setting (1 or 2) and then press CANCEL. The timer operation follows the clock setting and will repeat daily once set.

AUTO: The POWER indicator blinks at the initial stage. The unit selects an operation mode every 10 minutes depending on the setting and room temperature.

HEAT: The POWER indicator blinks at the initial stage. The unit will take some time to warm up.

COOL: Provides efficient comfort cooling to suit your needs.

DRY: Operates at a low fan speed for a gentle cooling operation. When FAN AUTO is selected, DRY mode will operate with humidity control.

FAN: To circulate air in the room.

You may save energy when operating the unit within the recommended temperature range:

HEAT: 68 °F ~ 75 °F / 20.0 °C ~ 24.0 °C.

COOL: 79 °F ~ 82 °F / 26.0 °C ~ 28.0 °C.

Use the air conditioner in the temperature range indicated in the table below. (DBT: Dry bulb temperature, WBT: Wet bulb temperature)

Regular cleaning is required to ensure the unit is at optimal performance. Before cleaning, always switch off the power at the circuit breaker.

General Precautions:

• Do not touch the aluminum fin as the sharp parts may cause injury.

• Do not use benzine, thinner, or scouring powder.

• Use soap (pH 7) or neutral household detergent only.

• Do not use water hotter than 104 °F / 40 °C.

Indoor unit: Wipe the unit gently with a soft damp cloth. The coils and fans should be cleaned periodically by an authorized dealer.

Outdoor unit: Clean the debris that surrounds the unit and clear any blockage from the drain pipe.

Front panel: Wash gently and dry.

Air filters (Once every 2 weeks):

1. Raise up and remove the front panel. Slide it to the right and pull out.

2. Remove the air filters from the unit.

3. Wash/rinse the filters gently with water to avoid damaging the surface.

4. Dry the filters thoroughly under a shade, away from fire or direct sunlight.

5. Attach the air filters and close the front panel securely.

This is a preliminary step to prepare for the TIMER operation after it has been set. When the Timer is set ON, the unit may start earlier (up to 35 minutes) before the actual set time to achieve the desired temperature on time.

The unit is in defrost mode. This is normal operation to melt frost that may have formed on the outdoor unit.

When the Timer has been set, the Timer setting repeats daily. The indicator will remain on to show that a timer is active.

The delay is a protection feature for the unit’s compressor to prevent damage from short-cycling.

The lowest fan speed is designed for low noise operation. As a result, the cooling/heating capacity may be reduced depending on the condition. To increase the capacity, increase the fan speed.

You can operate the unit directly from the indoor unit’s control button:

1. Raise the front panel.

2. Press the button once to use in AUTO mode.

3. Press and hold the button until you hear 1 beep, then release to use in forced COOL mode.

4. Repeat step 3. Press and hold the button until you hear 2 beeps, then release to use in normal COOL mode.

5. Repeat step 4. Press and hold the button until you hear 3 beeps, then release to use in forced HEAT mode.

6. Press the button again to turn off.

Follow these steps:

1. Activate HEAT mode for 2-3 hours to remove any moisture left in the internal parts thoroughly. This helps prevent mold growth.

2. Turn off the power supply and unplug the unit.

3. Remove the batteries from the remote control.

Switch off the power at the circuit breaker and consult an authorized dealer in the following conditions:

• Abnormal noise during operation.

• Water/foreign particles have entered the remote control.

• Water leaks from the indoor unit.

• Circuit breaker switches off frequently.

• Power cord becomes unnaturally warm.

• Switches or buttons are not functioning properly.

If the unit stops and the TIMER indicator blinks, use the remote control to retrieve the error code:

1. Press and hold the down arrow in the timer CHECK section for 5 seconds.

2. Press the up or down arrow until you hear a beep sound, then write down the error code displayed.

3. Press and hold the down arrow again for 5 seconds to quit checking.

4. Turn the unit off and inform the error code to an authorized dealer.
