gases, or in an extremely humid space such as a greenhouse.
• Do not install the air conditioner where excessively high heat-
generating objects are placed.
Avoid: To protect the air conditioner from heavy corrosion, avoid installing the outdoor
unit where salty sea water can splash directly onto it or in sulphurous air near a
spa.
• Never use or store gasoline or other flammable vapor or liquid near the
air conditioner — it is very dangerous.
• This air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you use
gas or oil heating appliances in the same room, which consume a lot of
oxygen from the air. Otherwise there is a risk of suffocation in an
extreme case.
• Do not turn the air conditioner on and off from the power mains switch.
Use the ON/OFF operation button.
• Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.

Special Remarks
How it works? • Once the room temperature reaches the level that was set, the unit’s operation
frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower speed for
providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F or less.
Heating performance • Because this air conditioner heats a room by drawing in the heat of the
outside air (heat pump system), the heating efficiency will fall off when the
outdoor temperature is very low. If sufficient heat cannot be obtained with this
air conditioner, use another heating appliance together with it.
Defrosting • When the outdoor temperature is low, frost or ice may form on the heat
exchanger coil, reducing heating performance. When this happens, a
microcomputer defrosting system operates. At the same time, the fan on the
indoor unit stops and the OPERATION lamp lights up red and orange
alternately until defrosting is completed. Heating operation restarts after
several minutes. (This interval will vary slightly depending upon the outdoor
temperature and the way in which frost forms.)
Cold draft prevention • For several minutes after the start of heating operation, the indoor fan runs at
lower speed until the indoor heat exchanger coil has warmed up sufficiently.
However, the fan may remain stopped when the room temperature is low. This
is because the COLD DRAFT PREVENTION SYSTEM is operating.
• In the event of power failure, the unit will stop. When the power is resumed,
the unit will restart automatically within five minutes by the remote control unit.
Clicking sound is heard from
the air conditioner
• In heating or cooling operation, any plastic parts may expand or shrink due to
a sudden temperature change. In this event, a clicking sound may occur. This
is normal, and the sound will soon disappear.
• The remote control unit sends the setting condition to the air conditioner
regularly at five minute intervals.

Using the 1-Hour OFF Timer
Tips for Energy Saving
1. 1-Hour OFF Timer This function causes the unit to operate for one hour and then stop,
regardless of whether the unit is on or off when this button is pressed.
The indicator in the display indicates that this function is operating.
Setting procedure:
Regardless of whether the unit is operating or stopped, press the 1 HR. TIMER
button.
appears in the display.
Cancellation procedure:
Press the ON/OFF operation button to turn the unit off, wait for the unit to stop
operating, and then press the ON/OFF operation button again.
The 1-Hour Timer function is now cancelled and the unit operates normally.
• If, while the 1-Hour Timer function is operating, the 1HR. TIMER button is
pressed once to cancel the function and then again, the unit continues to
operate for one hour from that point in time and then stops.
• It is not possible to use the OFF Timer and 1-Hour OFF Timer together.
Whichever function is set last takes precedence. If the 1 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.
2. Operation together with the
DAILY ON/OFF REPEAT Timer
The 1-Hour OFF Timer setting is given priority over the DAILY ON/OFF REPEAT
setting.
Do not • Block the air intake and outlet of the unit. If they are obstructed, the unit
will not work well, and may be damaged.
• Let direct sunlight into the room. Use sunshades, blinds or curtains. If the walls
and ceiling of the room are warmed by the sun, it will take longer to cool the
room.
Do • Always try to keep the air filter clean. (Refer to “Care and Cleaning”.) A
clogged filter will impair the performance of the unit.
• To prevent conditioned air from escaping, keep windows, doors and any other
openings closed.
