REQUIREMENT
[In Cooling operation]
• The operation will start after approximately 1 minute.
[In Heating operation (For Heat-pump model only)]
• In heating operation, the fan operation may continue for approximately 30 seconds after the air condi-
tioner has stopped.
• The indoor fan will continue the preheat operation for 3 to 5 minutes under stop conditions. The indoor
unit will then begin to blow out hot air.
(
symbol on the remote controller display will come on.)
• When the temperature of the room has reached the setup temperature and the outdoor unit stops, the air
speed reduces and so the air volume will decrease.
• In HEAT mode, if the room temperature reaches the set temperature, the outdoor unit will stop and
the air flow / volume will decrease.
• In the defrost mode, the fan will stop so that cool air is not discharged and the PRE-DEF is displayed.
ADJUSTMENT OF WIND DIRECTION
To increase the cooling or heating effect, be sure to use the discharge flap in different direc-
tions when in cooling or heating operation.
The characteristics of air are such that cold air will accumulate in the lower half of the room, while hot air will
accumulate in the upper half.
CAUTION
Set the flap horizontally in cooling operation.
If a cooling operation is performed with a downwards discharge, the surface of the discharge port or flap
will become wet with dew, and water may drip down.
REQUIREMENT
• If a heating operation is performed with a horizontal discharge, unevenness the room temperature may
not be equal i.e. there may be a large variance between one side of the room with the other.
4-way Air Discharge Cassette Type
• When the air conditioner is not in operation, the
discharge flap will automatically directs downwards.
• When the air conditioner is in ready status for heat-
ing, the discharge flap will be directed upwards.
The swinging operation will begin after heating
ready status has been cleared. Please note the
“SWING
” symbol will still be displayed on the
remote controller even when the unit status is ready
to begin the heating operation.
[In Cooling operation]
Use the discharge flap with a horizontal set point.
[In Heating operation (For Heat-pump model only)]
Use the discharge flap with a downwards set point.
