• When the HIGH POWER button is pressed, the unit operates at
maximum output for 30 minutes, regardless of the desired
temperature. The fan speed is 1 step above “High”.
• HIGH POWER Mode cannot be used when the operation mode is
in Automatic Operation.
• When set to High fan speed during heating operation, the fan runs
at High fan speed even though the
mark is displayed.
• Depending on the operating conditions, the fan speed may be
increased by a small amount only.
SPECIAL REMARKS
How it works?
• Once the room temperature reaches the level that was set, the
unit’s operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower
speed for providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F
or less.
Heating performance
• Because this air conditioner heats a room by drawing in the heat of
the outside air (heat pump system), the heating efficiency will fall
off when the outdoor temperature is very low. If sufficient heat
cannot be obtained with this air conditioner, use another heating
appliance together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may form on the
heat exchanger coil, reducing heating performance. When this
happens, a microcomputer defrosting system operates. At the
same time, the fan on the indoor unit stops and the OPERATION
lamp lights red and orange alternately until defrosting is completed.
Heating operation restarts after several minutes. (This interval will
vary slightly depending upon the outdoor temperature and the way
in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating operation, the indoor
fan runs at a lower speed until the indoor heat exchanger coil has
warmed up sufficiently. However, the fan may remain stopped when
the room temperature is low. This is because the COLD DRAFT
PREVENTION SYSTEM is in operation.
• Sometimes the indoor unit may not get to the set fan speed such as
LOW under cool operation at very low outdoor temperatures due to
the indoor unit being protected from ice or frost.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically in approximately
5 minutes, or 15 minutes at M position of the S/M switch on AUTO
mode by the remote controller.
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts may expand or
shrink due to a sudden temperature change. In this event, a
clicking sound may occur. This is normal, and the sound will soon
disappear.
• The remote controller sends the setting condition to the air
conditioner regularly at five minute intervals.
