Use the PANASONIC CU-2E18CBPG air conditioner under the following temperature ranges for optimal performance:

*DBT: Dry bulb temperature

*WBT: Wet bulb temperature

NOTICE: This model is not suitable for 24-hour non-stopping operation in heating mode below -5°C. When the outdoor temperature is below -5°C and you use this model outside of the above conditions, the outdoor unit might freeze up and stop operation for protection control.

Multi air conditioner systems, like the PANASONIC CU-2E18CBPG, save space by allowing you to connect multiple indoor units to a single outdoor unit. Here’s how they operate:

• It is possible to operate the indoor units individually or simultaneously. The operation mode priority is given to the first unit that is turned on.

• During operation, heating and cooling modes cannot be activated at the same time for different indoor units. The power indicator will blink to indicate that an indoor unit is on standby for a different operation mode.

Caution: PATROL and e-ion operations can be activated even when the air conditioner is turned off. In this state, the unit will operate with AUTO fan speed and air swing. However, this operation cannot be activated or will be deactivated if another indoor unit is currently in heating mode.

You can use the Auto OFF/ON button on the indoor unit when the remote control is misplaced or malfunctioning.

The indicator lights on your PANASONIC CU-2E18CBPG provide information about its status:

To select an operation mode, press the MODE button on the remote control. The recommended temperature settings for energy saving are: HEAT mode: 20°C ~ 24°C; COOL mode: 26°C ~ 28°C; DRY mode: 1°C ~ 2°C lower than room temperature.

• AUTO mode: For your convenience. The unit selects the operation mode every 3 hours according to the temperature setting, outdoor, and room temperature. The power indicator blinks during mode selection.

• HEAT mode: To enjoy warm air. The unit takes a while to warm up, and the power indicator blinks during this operation.

• COOL mode: To enjoy cool air.

• DRY mode: To dehumidify the environment. The unit operates at a low fan speed for gentle cooling.

• e-ion (To enjoy clean & fresh air): This feature generates negative ions to produce a fresh air effect and attract dust, which is then captured by the positively charged e-ion filters.

• PATROL (To monitor air quality): The patrol sensor detects air quality. When the air quality is unsatisfactory, the e-ion operation will start automatically.

• QUIET (To enjoy a quiet environment): This operation reduces airflow noise.

• POWERFUL (To achieve temperature quickly): This mode helps the unit reach the desired temperature faster.

Please note the following operating rules:

• PATROL, e-ion, QUIET, and POWERFUL can be activated in all modes and can be canceled by pressing the respective button again.

• PATROL, e-ion, QUIET, and POWERFUL cannot be selected at the same time as MILD DRY COOLING.

• PATROL and e-ion can be activated even when the unit is turned off. In this condition, fan speed and air swing cannot be adjusted.
