NOTE
• For machine protection the system may con-
trol the air flow rate automatically.
• The air flow rate may be adjusted automati-
cally depending on the room temperature or
the fan may stop immediately. This is not a
malfunction.
• It may take sometime for finishing to change
the air flow rate.
This is normal operation.
Press air flow direction adjust button.

The operation lamp goes off and the system
stops operation.
NOTE
• The fan may keep on running for about
1 minute after the heating operation stops
for removing the heat in the indoor unit.
• Do not turn off the power immediately after
the unit stops.
The system need at least 5 minutes for
residual operation of drain pump device.
Turning off the power immediately will cause
water leak or trouble.
EXPLANATION OF HEATING OPERATION
• For general heating operation, it may take longer to
reach the set temperature than in cooling operation.
We recommend starting the operation which was
used before using timer operation.
• The following operation is performed in order to
prevent the heating capacity from dropping or
cold air from blowing.
Defrost operation
• In heating operation, freezing of the outside
unit coil increases. Heating capability
decreases and the system goes into defrost
operation.
• The airflow will be set to breeze or stop.
• If stopped, the display of the remote control-
ler shows "
• Once the airflow is set to breeze or stop, the
air conditioner will return to the previous
state in approximately 5 to 15 minutes.

Hot start
• In order to prevent cold air from blowing out
of an indoor unit at the start of heating oper-
ation, the indoor fan is automatically
stopped. The display of the remote controller
shows " ".
• The heating capacity drops as the outside tem-
perature falls. If this happens, use another heat-
ing device together with the unit. (When using the
appliances which produce open fire together, ven-
tilate a room constantly.)
Do not place appliances which produce open fire
in places exposed to the air flow from the unit or
under the unit.
• It takes some time for the room to warm up from
the time the unit is started since the unit is a hot-
air circulatory system to warm the entire room.
• If the hot air rises to the ceiling, leaving the area
above the floor cold, we recommend using the cir-
culator (the indoor fan for circulating air). Contact
your dealer for details.
6-2 PROGRAM DRY OPERATION
• The program dry function deprives the room
of moisture while the air conditioner is in inter-
mittent weak cooling operation so that the
room temperature will not become too low.
• The microcomputer automatically controls
the temperature and fan speed, so these
cannot be set using the remote controller.
• This function is not available if the room tem-
perature is 68°F or lower.
• This function does not controls the humidity.
• FXL and FXN type indoor unit can not oper-
ate program dry operation.

TOR (Refer to figure 5)
