Warning
If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite.
Prohibit
If refrigerant gas leaks during the work, ventilate the room.
If refrigerant gas catches fire, harmful gas may be generated.
Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.
If air or other contaminants mix with the gas, pressure will become extremely high in the refrigerating cycle,
which may cause a unit breakdown."
Prohibit
When the welded section of the compressor intake or discharge pipe is to be disconnected, perform it in
a well-ventilated place after sufficiently recovering the refrigerant gas.
Any residue gas may jet out refrigerant or refrigerating machine oil, which may cause an injury.
When the work is to be performed in a high place (About 2 meters or more), make sure to wear a safety helmet,
gloves and safety belt. Insufficient safety gear may cause a serious injury in case of a fall.
When the unit is to be relocated, confirm that the new installation location has sufficient strength for the weight of the unit.
Insufficient strength of the installation location and incomplete installation work may cause an injury due to
the unit falling.
When the remote controller batteries are replaced, dispose of the old batteries out of the reach of children.
If a child swallows a battery, make sure that the child gets immediate medical attention.
Caution
Do not wash the air conditioner with water, as this may cause an electric shock or fire.
Prohibit
For the repair work in places with high humidity or moisture, make sure to ground the unit.
Failure to do so may cause an electric shock.
Confirm that the component attachment position, wiring condition, soldering condition and connector connection
are normal.
If not, it may cause overheating or fire.
Confirm that the temperature around the compressor is not too high, and then perform the repair work.
Failure to do so may cause a burn.
Perform welding work in a place with good ventilation.
If the work is performed in a poorly ventilated area, it might cause a lack of oxygen.
If the installation plate or attachment frame has deteriorated due to corrosion, etc., replace it.
Failure to do so may cause an injury due to the unit falling.
When the cleaning is to be performed, make sure to turn off the power and pull out the plug.
Touching the fan that is rotating at high speed may result in an injury.
When the indoor unit is to be removed, do not place it on an incline.
Doing so may cause wet furniture because water left inside may trickle down.
Prohibit
Prohibit
Do not hold the sharp end of the unit or the aluminum fins, as it may cause an injury to your hand or finger.
After repairs, make sure to measure the insulation resistance and confirm that the value is 1 Mohm or more.
Any insulation error may cause an electric shock.

HR. TIMER button is pressed while the TIMER OFF function
operates, the OFF Timer is cancelled and the unit will stop
operating one hour later.
NOTE
• The flap automatically closes when the unit is off.
• During the heating operation, the fan speed will be very low and the
flap will be in the horizontal position (position ) until the air being
blown out of the unit begins to warm. Once the air warms up, the
flap position and fan speed change to the settings specified with
the remote controller.
CAUTION
2. Operation together with the daily ON/OFF
repeat timer
• Use the FLAP button on the remote controller to adjust the
position of the flap. If you move the flap by hand, the flap
position according to the remote controller and the actual
flap position may no longer match. If this should happen,
shut off the unit, wait for the flap to close, and then turn on
the unit again; the flap position will now be normal again.
• Do not have the flap pointed down during cooling operation.
Condensation may begin to form around the air vent and drip
down.
The 1-Hour OFF Timer setting is given priority over the DAILY ON/
OFF REPEAT setting.
