÷ If the unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
÷ Whenever the Power is disconnected and then reconnected to
a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.
÷ During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).
÷ During operation, a slight squeaking sound may be heard. This
is the result of minute expansion and contraction of the front cover due to temperature changes.
÷ Some smell may be emitted from the indoor unit. This smell is
the result of room smells (furniture, tobacco, etc.) which have been taken into the air conditioner.
÷ During Cooling or Dry operation, a thin mist may be seen
emitted from the indoor unit. This results from the sudden Cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.
÷ The fan may operate at very low speed during Dry operation
or when the unit is monitoring the room’s temperature.

TROUBLE SHOOTING

CHECK ONCE
MORE
WARNING!
Symptom
Doesn’t operate at all:
Poor Cooling performance:
The unit operates differently from the remote control unit's setting:
If the problem persists after performing these checks, or if you notice burning smells, or the TIMER Indicator Lamp (Fig. 3, 6) flashes, immediately stop operation, disconnect the Power and consult authorized service personnel.
Items to Check
÷ Has there been a power failure? ÷ Has a fuse blown out, or a circuit breaker been tripped?
÷ Is the POWER switch set to the OFF position?
÷ Is the timer operating?
÷ Is the air filter dirty? ÷ Are the air conditioner’s intake grille or outlet port blocked? ÷ Did you adjust the room temperature settings (thermostat)
correctly?
÷ Is there a window or door open? ÷ Is a window allowing bright sunlight to enter? (Close the curtains.) ÷ Are there heating apparatus and computers inside the room, or
are there too many people in the room?
÷ Is the unit set for SUPER QUIET operation?
÷ Are the Remote Control Unit's batteries dead? ÷ Are the Remote Control Unit's batteries loaded properly?

OPERATING TIPS

Operation and Performance
In Event of Power Interruption
Auto Restart
÷ The air conditioner power has been interrupted by a
power failure. The air conditioner will then restart automatically in its previous mode when the power is restored.
÷ Operated by settings before the power failure. Then, the
Air Flow Direction Louvers will automatically change to their standard direction.
÷ If a power failure occurs during TIMER operation, the
timer will be reset and the unit will begin (or stop) operation at the new time setting. In the event that this kind of timer fault occurs, the TIMER Indicator Lamp (green) will flash (see page 5).
÷ Use of other electrical appliances (electric shaver, etc.)
or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the Power, reconnect it, and then use the Remote Control Unit to resume operation.

÷ If the air conditioner is used under higher temperature conditioner than those listed, the built-in protection circuit may
operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is used under conditions of lower temperature than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
÷ Do not use this unit for any purposes other than the Cooling, and Dehumidifying, and air-circulation of rooms in ordinary
dwellings.
