▪ NEVER touch the internal parts of the controller.
▪ Do NOT remove the front panel. Some parts inside are
dangerous to touch and appliance problems may
happen. For checking and adjusting the internal parts,
contact your dealer.
CAUTION
Do NOT touch the heat exchanger fins. These fins are
sharp and could result in cutting injuries.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. Do NOT remove the fan guard. When the
fan is rotating at high speed, it will cause injury.
WARNING
Do NOT place a flammable spray bottle near the air
conditioner and do NOT use sprays. Doing so may result in
a fire.
CAUTION
It is not good for your health to expose your body to the air
flow for a long time.
CAUTION
To avoid oxygen deficiency, ventilate the room sufficiently
if equipment with burner is used together with the system.
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.
CAUTION
NEVER expose little children, plants or animals directly to
the airflow.
NOTICE
Never press the button of the remote controller with a hard,
pointed object. The remote controller may be damaged.

NOTICE
Do not place the user interface in a place exposed to direct
sunlight. The LCD display may get discoloured or fail to
display the data.
NOTICE
Do not place items which might be damaged by moisture
under the indoor unit. Condensation may form if the
humidity is above 80%, if the drain outlet is blocked or the
filter is polluted.
NOTICE
Arrange the drain hose to ensure smooth drainage.
Incomplete drainage may cause the building, furniture, etc.
to get wet.
NOTICE
Be sure to turn on the power 6 hours before operation in
order to have power running to the crankcase heater and
to protect the compressor.
NOTICE
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Only use
accessories, optional equipment and spare parts made or
approved by Daikin.
