Energy saving and optimum
operation
CAUTION
Never expose little children, plants or animals directly to
the air flow.
WARNING
Do NOT place objects below the indoor and/or outdoor unit
that may get wet. In this condition, condensation on the
main unit or refrigerant pipes, air filter dirt or drain blockage
may cause dripping. This results in fouling or failure of the
object which is located beneath the unit.
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.
CAUTION
Do not operate the system when using a room fumigation-
type insecticide. This could cause the chemicals to
become deposited in the unit, which could endanger the
health of those who are hypersensitive to chemicals.
WARNING
Do not place a flammable spray bottle near the air
conditioner and do not use sprays. Doing so may result in
a fire.
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.
▪ 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. It
may cause deterioration in the effect or stop the operation.
▪ Turn off the main power supply switch to the unit when the unit is
not used for longer periods of time. If the switch is on, it consumes
electricity. Before restarting the unit, turn on the main power
supply switch 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.

Maintenance and service
5.1
Overview: Maintenance and
service
The installer has to perform a yearly maintenance.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
NOTICE
In Europe, the
greenhouse gas emissions
of the total
refrigerant charge in the system (expressed as tonnes
CO
2
-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
NOTICE
Maintenance must be done by an authorised installer or
service agent.
We recommend to do maintenance at least once a year.
However, applicable legislation might require shorter
maintenance intervals.
CAUTION
Before accessing terminal devices, make sure to interrupt
all power supply.
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
electric shock and injury may result.
WARNING
To prevent electric 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.
