"PAUSE" Indicator
"RUN" Indicator
It lights up to indicate that the
unit is operating:
AUTO (Automatic)
HEAT (Heating)
COOL (Cooling)
SWEEP (Fan only)
DRY (Dehumidifying).
It lights up during automatic
defrosting, or when the preheating function for the indoor
heat exchanger is active (i.e.
when operation in Heating
mode starts).
ON/OFF Switch
For emergency operation in AUTO mode (if
the remote controller
is not available). Press
it again to stop the
unit.
"TIMER" Indicator
It lights up to indicate
that the unit's operation
has been programmed
by the Timer.
"AIR REFRESH" Indicator
It refers to a function which
is unavailable on these models.
Set temperature display
The desired temperature value is
displayed, as set by the User
through the infrared remote
controller.
Current indoor fan speed setting indicator
Indoor fan is set at "HIGH" speed
Indoor fan is set at "MEDIUM" speed
Indoor fan is set at "LOW" speed
NOTES:
If the current indoor fan speed setting indicator is flashing, this means that
"AUTO" fan speed has been selected.
1. Do not put fingers or sticks into the air inlet or air outlet of the indoor unit.
2. Touching the indoor fan which rotates at high speed, may result in serious injuries. Moreover the
aluminium fins on the heat echanger are sharp-edged. As a consequence, particular attention must
be observed when the front panel of the indoor unit has been opened for maintenance or air filters
cleaning. It is strongly adviced to switch off the main power line and wait some minutes before
carrying on the inspection work.
3. If the "RUN" indicator flashes, this means that a malfunction has occurred. In such cases, it is
required to contact a Service Agent.

8.2.2 The air conditioner do not run
8.2.2.1 Check the switch power.
① Without 30V DC output from two ends of the capacitor C405 (the indicator does not light).
A. Check 240V power supply, power socket → power cord → fuse(3.15A /220V) → high voltage
capacitor C410 (whether there is 280 ~ 300V DC or not)
B. Check the capacitor C405

Ok
Ok
C. Check the switch transformer for sounding. If the transformer sounds, remove the load on the power
supplies of 30V DC and 12V DG. If still without 30V DC output after removal, then the switch power is
defective. If with 30V DC output, the load is short – circuited but the switch power is good. Then check
the secondary load circuit.

9. Checking Electrical Components
9.1 Measure insulation resistance
The insulation is in good condition if the resistance
exceeds 2 MΩ.
9.1.1 Power supply wires
Clamp the ground pins of the power plug with the lead clip
of the insulation resistance tester and measure the
resistance by placing a probe on either of the power wires.
(Fig. 1)
Then measure the resistance between the
ground wire and the other power wire. (Fig. 1)
9.1.2 Indoor unit
Clamp an aluminum plate fin or copper tube with the lead
clip of the insulation resistance tester and measure the
resistance by placing a probe on each terminal screw on the terminal plate. (Fig. 2)
Note that the ground line terminal should be skipped for the check.
9.1.3 Outdoor unit
Clamp a metallic part of the unit with the lead
clip of the insulation resistance tester and
measure the resistance by placing a probe on each terminal
screw where power supply lines are connected on the
terminal plate. (Fig. 2)
9.1.4 Measurement of Insulation Resistance for Electrical Parts
Disconnect the lead wires of the desired electric part from terminal plate. Capacitor, etc.
Similarly disconnect the connector. Then measure the insulation
resistance. (Fig. 3 and 4)
9.2 Checking continuity of fuse on PCB ass”y
Remove the PCB ass’ y from the electrical component box. Then
pull out the fuse from the PCB ass’ y. (Fig. 5)
Check for continuity using a multimeter as shown in Fig. 6
9.3 Checking motor capacitor
Remove the lead wires from the capacitor terminals, and then
place a probe on the capacitor terminals as shown in Fig. 7.
Observe the deflection of the pointer setting the resistance
measuring range of the multimeter to the maximum value.
The capacitor is “good” if the pointer bounces to a great extent
and then gradually returns to its original position.
The range of deflection and deflection time differ according to
the capacity of the capacitor.
Refer to electric wiring diagram.
If the probe can’ t enter the p oles because
the hole is too narrow then use a probe with
a thinner pin.

While the air conditioner is operating, hold the "TIME" button pressed, until the symbol is shown
on the LCD screen of the remote controller, this indicates that the "SLEEP" function (which allows
relevant energy saving) is now enabled.
To disable the "SLEEP" function, hold the "TIME" button pressed, until the symbol
disappears from the LCD screen of the remote controller; this indicates that the "SLEEP" function is
now disabled.
The "SLEEP" function cannot be enabled when the current operating mode is "AUTO" (Automatic) or
"SWEEP" (Fan only).
When the "SLEEP" function is enabled, during operation in Cooling and Dehumidifying modes, the
set temperature will be increased by 1˚C one hour later; during operation in Heating mode, the set
temperature will be decreased by 1˚C one hour later. The set temperature will be controlled between
16˚C and 32˚C.
When the "SLEEP" function is enabled, the indoor fan speed is automatically set to "MEDIUM"
(middle speed), but this setting can be modified by the User through the remote controller.
When the "SLEEP" function is enabled, the LED display on the indoor unit will turn off 30 seconds
after a signal from the remote controller was received.
When the "SLEEP" function is enabled, only the "RUN" indicator will light up to show that the air
conditioner is operating.
When the "SLEEP" function is enabled, the buzzer on the indoor unit will not beep when a signal is
received from the remote controller, but, if the operation settings are changed, the relevant lamps on
the indoor unit will light up for about 30 seconds. After this time has elapsed, only the "RUN" indicator
will light up to show that the air conditioner is operating.
If the "TIME" button is hold pressed while the "SLEEP" function is enabled, the function itself will be
disabled; in this case the buzzer on the indoor unit will beep and the relevant indicators on the indoor
unit's display will light up as during normal operation.
