NOTE
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).
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.

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.).
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 is automatically set to low speed
or stops to prevent overcooling.

2. Press the ON/OFF button and switch the air conditioner ON.

ADJUSTING THE FAN SPEED

AUTOMATIC
Simply set the FAN SPEED selector to the
. A microcomputer automatically controls the fan speed when the
. AUTO mode is selected. When the air conditioner starts operating,
the difference between the room temperature and the set
temperature is detected by the microcomputer which then
automatically switches the fan speed to the most suitable level.
In FAN Only mode the fan speed is adjusted automatically as in
cooling mode.
