Problem
●
If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent
fuse blowouts.
●
Whenever the Power Supply Plug is disconnected and then re-
connected 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.
●
During SUPER QUIET operation, the fan will operate at very low speed.
●
In the monitor AUTO operation, the fan will operate at very low speed.
●
Is the Power Supply Plug disconnected its outlet?
●
Has there been a power failure?
●
Has a fuse blown out, or a circuit breaker been tripped?
●
Is the timer operating?
●
Is the Air Filter dirty?
●
Air 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?
●
In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)
●
In the case of Cooling operation, 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?

FUNCTION
CHECK ONCE
MORE
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the elec-
trical breaker or disconnect the power supply plug, and consult authorized service personnel.
Merely turning off the unit’s power switch will not completely disconnect the unit from the power
source. Always be sure to turn off the electrical breaker or disconnect the power supply plug to
ensure that power is completely off.
Before requesting service, perform the following checks:
If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp
(Fig. 3
5
) and the TIMER Indicator Lamp (Fig. 3
6
) flashes, immediately stop operation, disconnect the Power Supply Plug
(Fig. 1
D
), and consult authorized service personnel.
