ECONOMIC OPERATION
When your push ECONO button during cooling, heating
(cooling only type without), or AUTO operation, the air
conditioner will start following operation. The fan speed
will be automatically controlled. In the operation suppression
zone where capacity is kept to the minimum, overcooling is
prevented by raising the temperature setting by 1 C after 1
hour and by 2 C after 2 hours of operation. The room
temperature is thus regulated between the operation
suppression zone and the set temperature. (It depends on
the outdoor temperature.)
DRY OPERATION
The dry mode will automatically select the cooling dry
operation based on the difference between the set
temperature and the actual room temperature.

AIR CONDITIONER OPERATIONS AND PERFORMANCE
Three-minute protection feature
A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it is
restarted immediately after operation.
This will protect the machine. (cooling only type without)
Heating characteristics preheating operation
The air conditioner will not deliver warm air immediately after it is started. Warm air flows out after
approximately 5 minutes when the indoor heat exchanger warms up.
Warm air control
When the room temperature reaches the set temperature, the fan speed is automatically reduced to
prevent a cold draft. At this time, the outdoor unit will stop.
Defrosting
If the outdoor unit is frosted during heating operation, defrosting is started automatically (for approximately
5 to 10 minutes) to maintain the heating effect, and the PRE.-DEF. lamp is on.
The fans in both the indoor and outdoor units stop during the defrost operation.
During defrost operation, defrosted water is drained from the bottom plate of the outdoor unit.
Heating capacity
In the heating operation, heat is absorbed from outdoor and released into the room. that is so-called heat
pump system. When the outdoor temperature is too low, you are recommended to use another heating
apparatus in combination with the air conditioner.
Consideration for accumulated snow
Select the position for the outdoor unit where it will not be subject to snow drifts, accumulation of leaves
or other seasonal debris. It is important that the air flow for the outdoor unit is not impeded as this will result in
reducing heating or cooling performance. During the heating mode (cooling only type without) and at sub-zero
temperatures, the water drained off the outdoor unit as a result of the automatic defrost may accumulate and
freeze. It is important that adequate drainage or a soak way is provided.
Power failure
Power failure during operation will stop the unit completely.
The OPERATION lamp on the indoor unit will start flashing when power is restored.
To restart operation, push the ON/OFF button on the remote controller.
Lighting or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit
with the power and then connect the unit with the power again. Push the ON/OFF button on the remote
controller to restart it.
