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.
Refer to the chapter “6-3 ADJUSTING THE
AIR FLOW DIRECTION” for details.
STOPPING THE SYSTEM (Refer to figure 4)
Press the on/off button once again.
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.
FOR SYSTEMS WITHOUT COOL/HEAT SELEC-
TOR (Refer to figure 5)
NOTE
•
If “
” (Cooling operation) is not displayed, refer
to “6-1 COOLING, HEATING, AUTOMATIC AND
FAN ONLY OPERATION”, and set “
” (Cooling
operation).
Unless the air conditioner is set to “
” (Cooling
operation), the air conditioner cannot be switched
over to “
” (program dry operation).
