Overview
Equipment Condition Remedy
1 Equipment does not operate. See page 3-6
2 Fan operates, but compressor does not. See page 3-6
3 Cooling/heating operation starts but stops
immediately. See page 3-10
4 After unit shuts down, it cannot be
restarted for a while. See page 3-12
5 Equipment operates but does not provide

9 Equipment discharges dust. See page 3-20
10 Remote controller LCD displays “88.” See page 3-21
11 Indoor swing flap does not operate. See page 3-22
12 Equipment emits odor. Room smell and cigarette odors accumu-
lated inside the indoor unit are discharged
with air. Inside of the indoor unit must be
cleaned.
13 Flap operates when power is turned on. It is normal. The flap initializes for accurate
positioning.
14 Change of operation mode causes flap to
move. It is normal. There is a control function that
moves the flap when operation mode is
changed.
15 Fan operates in “M” mode during heating
even if remote controller is set to “Low.” It is normal. It is caused by the activation of
the overload control (airflow shift control).
16 Flap automatically moves during cooling. It is normal. It is caused by the activation of
the dew prevention function or ceiling soil-
ing prevention function.
17 Indoor unit fan operates in “L” mode for 1
minute in microcomputer-controlled dry
mode even if compressor is not operating. It is normal. The monitoring function forci-
bly operates the fan for one minute.
18 In simultaneous ON/OFF multi-system
setup, indoor unit (sub) does not operate in
sync with the other indoor unit (main).
(Flat, fan, etc.)
It is normal. It is caused by a signal trans-
mission lag.
19 Indoor unit fan operates after heating oper-
ation stops. It is normal. The fan operates in the “LL”
mode for 60 to 100 seconds to dissipate
the residual heat in the heater.
20 Drain pump operates when equipment is
not operating. It is normal. The drain pump continues to
operate for several minutes after equip-
ment is turned off.
21 Horizontal swing sends air to different
directions in cooling and heating even if it
is set to the same position. It is normal. The airflow direction in cool-
ing/dry operation is different from that in
heating/fan operation.
22 Flap remains horizontal even if it is set to
Swing. It is normal. The flap does not swing in the
thermostat OFF mode.
