low speed until the heat exchanger reaches the set tempera-
ture.

OPERATING TIPS
Instructions relating to heating (*) are applicable only to
Heating and Cooling model (Reverse Cycle).
Heating performance*
z
This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. Also, please consult with
your installation technician to ensure the unit is correctly
sized for the room space required.
z
Heat-pump air conditioners heat your entire room by recir-
culating air throughout the room, with the result that some
time may be required after rst starting the air conditioner
until the room is heated.
When indoor and outdoor temperatures are high*
When both indoor and outdoor temperatures are high during
use of the Heating mode, the outdoor unit’s fan may stop at
times.
Microcomputer-controlled automatic defrosting*
z
When using the Heating mode under conditions of low
outdoor temperature and high humidity, frost may form on
the outdoor unit, reducing the operating performance.
In order to prevent this kind of reduced performance,
this product is equipped with a microcomputer-controlled
automatic defrosting function. During the defrost cycle,
the indoor fan will shutdown and the defrost mode will be
indicated. It will take maximum of 15 minutes before the air
conditioner starts up again.
z
After Heating operation stops, if frost forms on the outdoor
unit, the unit will start Automatic defrosting operation.
At this time, the outdoor unit will automatically stop after
operating for a few minutes.

ferent position at the start of heating operation, during
defrost, or when AUTO(auto changeover) is selected.
