Energy saving and optimum
operation
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.
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.
▪ 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.

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

Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a

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).
DANGER: RISK OF ELECTROCUTION
To clean the air conditioner or air filter, be sure to stop
operation and turn all power supplies OFF. Otherwise, an
electrical shock and injury may result.
WARNING
To prevent electrical shocks or fire:
▪ Do NOT rinse the unit.
▪ Do NOT operate the unit with wet hands.
▪ Do NOT place any objects containing water on the unit.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
