AUTOMATIC OPERATION
HEATING
HEATING PERFORMANCE
A heat pump conditioner heats a room by taking heat from outside
air. The heating efficiency will fall off when the outdoor temperature
is very low. If enough heat is not obtained with this air conditioner,
use another heating appliance in conjunction with it.
For several minutes after the start of heating operation, the indoor
fan will not run until the indoor heat exchanger coil has warmed
up sufficiently. This is because the COLD DRAFT PREVENTION
SYSTEM is operating.
DEFROSTING OF HEAT EXCHANGER
OUTDOOR UNIT “STANDBY”
When the outdoor temperature is low, frost or ice may appear on
the heat exchanger coil, reducing the heating performance. When
this happens, a microcomputer defrosting system operates. At
the same time, the fan in the indoor unit stops and the OPERATION
lamp is flashing until defrosting is completed. Heating operation
restarts after several minutes. (This interval will vary slightly
depending on the room and outdoor temperature).
HOW TO SET THE PRESENT TIME
1. Press the SET button for five seconds. The time indication
alone flashes.
2. Press the + or - buttons until the present time is displayed.
3. Press the SET button to stop the indication flashing.
COOLING
Verify that the unit is connected to the main
power and the STANDBY lamp is light up.
1.Set the MODE selector to COOL .
2.Press the ON/OFF button and switch the air
conditioner ON.
3.Press the TEMP. buttons to set the desired
temperature (the temperature range is
between 30 °C max. and 16 °C min.).
NOTE

TEMPERATURE.
4. Press the FAN SPEED button to select the fan speed.
5.Press the FLAP buttons and adjust the air flow direction as desired
(see adjustment of air flow). Make sure that the remote control is
switched on. Press the FLAP button to select automatic swing or
one of the six manual settings.
1.Set the MODE selector to HEAT .
2.Press the ON/OFF button and switch the air condioner ON.

When this setting is selected, the air conditioner calculates the
difference between the thermostat setting and the room temperature
and automatically switches to the COOL or HEAT mode as
appropriate.

DEHUMIDIFYING (DRY)
1.Set the MODE selector switch to “DRY” .
2.Press the ON/OFF button and switch the air condioner ON.
3.Press the TEMP. buttons to set the desired temperature (the
temperature range is between 30 °C max. and 16 °C min.).

NOTE
●Use DRY operation when you want to reduce the humidity in the
room.
●Once the room temperature reaches the set level, the unit
repeats the cycle of turning on and off automatically.
●During DRY operation, the fan speed is automatically set to low
or stops to prevent overcooling.
●Dry operation is not possible if the indoor temperature is 15 °C
or less.
NOTE
The air conditioner changes the operation mode (from cool to heat
or vice versa, if one of the following conditions occurs:
-ZONE A: changes if the difference between the room temperature
and the temperature set on the remote control unit is at least 3°C..
-ZONE B: changes if the difference between the room temperature
and the temperature set on the remote control unit is at least 1°C,
one hour after the compressor stop.
- ZONE C: never changes if the difference between the room
temperature and the temperature set on the remote control unit is
no more than 1°C.
