WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
NOTICE
Do NOT use the system for other purposes. In order to avoid any quality
deterioration, do NOT use the unit for cooling precision instruments, food, plants,
animals, or works of art.
3.1 Indoor unit
CAUTION
Do NOT insert fingers, rods or other objects into the air inlet or outlet. When the fan
is rotating at high speed, it will cause injury.
INFORMATION
The sound pressure level is less than 70dBA.
3 | About the system
WARNING
▪ Do not modify, disassemble, remove, reinstall or repair the unit yourself as
incorrect dismantling or installation may cause an electric shock or fire. Contact
your dealer.
▪ In case of accidental refrigerant leaks, make sure there are no naked flames. The
refrigerant itself is entirely safe, non-toxic and mildly flammable, but it will
generate toxic gas when it accidentally leaks into a room where combustible air
from fan heaters, gas cookers, etc. is present. Always have qualified service
personnel confirm that the point of leakage has been repaired or corrected
before resuming operation.

5.3 Operation mode and temperature setpoint
When. Adjust the system operation mode and set the temperature when you want
to:
▪ Heat up or cool down a room
▪ Blow air in a room without heating or cooling
▪ Decrease the humidity in a room
What. The system operates differently, depending on the user selection.
Setting Description
Automatic
Drying
The system cools down or heats up a room to
the temperature setpoint. It automatically
switches between cooling and heating if
necessary.
The system decreases the humidity in a room
without changing the temperature.
Heating
The system heats up a room to the temperature
setpoint.
Cooling
The system cools down a room to the
temperature setpoint.
Fan
The system only controls the airflow (airflow
rate and airflow direction).
The system does NOT control the temperature.
Additional info:
▪ Outside temperature. The system's cooling or heating effect decreases when the
outside temperature is too high or too low.
▪ Defrost operation. During heating operation, frost might occur on the outdoor
unit and decrease the heating capacity. In that case, the system automatically
switches to defrosting operation to remove the frost. During defrosting
operation, hot air is NOT blown from the indoor unit.

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.
▪ 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.

7 Maintenance and service
7.1 Overview: Maintenance and service
The installer has to perform a yearly maintenance.
About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent gases into the
atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO2 equivalent.
Formula to calculate the quantity in CO2 equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Please contact your installer for more information.
7 | Maintenance and service
WARNING
The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If the
refrigerant leaks in the room and comes in contact with fire from a burner, a heater,
or a cooker, this may result in fire, or the formation of a harmful gas.
Turn off any combustible heating devices, ventilate the room, and contact the dealer
where you purchased the unit.
Do NOT use the unit until a service person confirms that the part from which the
refrigerant leaked has been repaired.
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use cleaning materials or means to accelerate the defrosting process
other than those recommended by the manufacturer.
▪ Be aware that the refrigerant inside the system is odourless.
WARNING
The appliance shall be stored in a room without continuously operating ignition
sources (example: open flames, an operating gas appliance or an operating electric
heater).
NOTICE
Maintenance MUST be done by an authorized installer or service agent.
We recommend performing maintenance at least once a year. However, applicable
legislation might require shorter maintenance intervals.

8.1 Symptoms that are NOT system malfunctions
The following symptoms are NOT system malfunctions:
8.1.1 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.
8.1.2 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).
8.1.3 Symptom: A ticking sound is heard
This sound is generated when the unit slightly expands or contracts with changes in
temperature.
8 | Troubleshooting
8.1.4 Symptom: A whistling sound is heard
This sound is generated by the refrigerant flowing during defrost operation.
8.1.5 Symptom: A clicking sound during operation or idle time is heard
This sound is generated when the refrigerant control valves or electrical parts
operate.
8.1.6 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.
8.1.7 Symptom: The units can give off odours
The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it
again.
8.1.8 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.
