INFORMATION

Even if the unit is turned OFF, it consumes electricity.
- When the power turns back on after a power break, the previously selected mode will be resumed.

CAUTION

NEVER expose little children, plants or animals directly to the airflow.

NOTICE

Do NOT place objects below the indoor and/or outdoor unit that may get wet. Otherwise condensation on the unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, and objects under the unit may get dirty or damaged.

WARNING

Do NOT place a flammable spray bottle near the air conditioner and do NOT use sprays near the unit. Doing so may result in a fire.

WARNING

Keep any required ventilation openings clear of obstructions.

CAUTION

Do NOT operate the system when using a room fumigation-type insecticide. Chemicals could collect in the unit, and endanger the health of people who are hypersensitive to chemicals.

Observe the following precautions to ensure the system operates properly.

• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
• Make sure the area is well ventilated. Do NOT block any ventilation openings.
• Ventilate often. Extended use requires special attention to ventilation.
• Keep doors and windows closed. If the doors and windows remain open, air will flow out of your room causing a decrease in the cooling or heating effect.
• Be careful NOT to cool or heat too much. To save energy, keep the temperature setting at a moderate level.
• NEVER place objects near the air inlet or the air outlet of the unit. Doing so may cause a reduced heating/cooling effect or stop operation.
• Turn the breaker off when the unit is NOT used for longer periods of time. If the breaker is on, the unit consumes electricity. Before restarting the unit, turn the breaker on 6 hours before operation to ensure smooth running.
• Condensation may form if the humidity is above 80% or if the drain outlet gets blocked.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or cooling. Notice that it may take some time for the room temperature to reach the set temperature. Consider using the timer setting options.

7 | Energy saving and optimum operation

- Adjust the air flow direction to avoid cool air from gathering on the floor or warm air against the ceiling. (Up during cooling or dry operation to the ceiling and down during heating operation.)

- Avoid direct air flow to room inhabitants.

- Operate the system within the recommended temperature range (26\~28°C for cooling and 20\~24°C for heating) to save energy.

9.2 Symptoms that are NOT system malfunctions

The following symptoms are NOT system malfunctions:

9.2.1 Symptom: Airflow temperature is NOT high enough during Heat plus operation

• When the outdoor temperature is low and falls below freezing point, the airflow temperature may be insufficient.
• During multi-room operation with multi outdoor unit connection, discharge air temperature may be unable to reach a sufficient value.

9.2.2 Symptom: A sound like water flowing is heard

This sound is caused by the refrigerant flowing in the unit.
- This sound may be generated when water is flowing away from the unit during cooling or drying operation.

9.2.3 Symptom: A blowing sound is heard

This sound is generated when the direction of the refrigerant flow is changed (e.g. when switching from cooling to heating).

9.2.4 Symptom: A ticking sound is heard

This sound is generated when the unit slightly expands or contracts with changes in temperature.

9.2.5 Symptom: A whistling sound is heard

This sound is generated by the refrigerant flowing during defrost operation.

9.2.6 Symptom: A clicking sound during operation or idle time is heard

This sound is generated when the refrigerant control valves or electrical parts operate.

9.2.7 Symptom: A clapping sound is heard

This sound is generated when an external device sucks air out of the room (e.g. exhaust fan, extractor hood) while the doors and windows in the room are closed. Open the doors or windows, or turn off the device.

9.2.8 Symptom: White mist comes out of a unit (Indoor unit)

• When humidity is high during cooling operation (in oily and dusty places). If the interior of an indoor unit is extremely contaminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the interior of the indoor unit. Ask your dealer for details on cleaning the unit. This operation requires a qualified service person.
• When the air conditioner is changed over to heating operation after defrost operation. Moisture generated by defrost becomes steam and exits.

9.2.9 Symptom: The units can give off odours

The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it again.

9.2.10 Symptom: The outdoor fan rotates while the air conditioner is not in operation

• After operation has stopped. The outdoor fan continues to rotate for another 30 seconds for system protection.
• While the air conditioner is not in operation. When the outdoor temperature is very high, the outdoor fan starts to rotate for system protection.

9.2.11 Symptom: Fan speed does NOT correspond with the setpoint

• During cooling operation in Multi system, the indoor unit may change the fan speed to high, regardless of the user setting, in order to defrost the indoor unit heat exchanger.
• During Indoor unit quiet operation, when both outdoor and indoor ambient temperature is very high, the indoor unit increases the fan speed to protect the system.

9.2.12 Symptom: The fan setting during thermo off (keep dry function) differs from setting in the ONECTA app

If the fan setting during thermo off (keep dry function) is changed only by the ONECTA app, setting will be cancelled by the wireless remote control.
