OPERATING TIPS

Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
Heating Performance*
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. If you feel that insuffi cient
heating performance is being produced, we recommend you
use this air conditioner in conjunction with another kind of
heating appliance.
Heat-pump air conditioners heat your entire room by recircu-
●
lating air throughout the room, with the result that some time
may be required after fi rst starting the air conditioner until the
room is heated.
When Indoor and Outdoor Temperature
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.
Fan speed: AUTO
Heating*: The fan will operate at very low speed when the
temperature of the air issued from the indoor unit is
low.
Cooling: As the room temperature approaches that of the set
temperature, the fan speed becomes slower.
Fan: The fan runs at the low fan speed.
Microcomputer-controlled Automatic
Defrosting*
When using the heating mode under conditions of low outdoor
●
temperature and high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
unit is equipped with a microcomputer-controlled automatic
defrosting function. During the defrost cycle, the indoor fan will
shutdown and will be displayed on the remote control-
ler. It will take anywhere from 4 to 15 minutes before the air
conditioner starts up again.
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.
Low Ambient Cooling
When the outdoor temperature drops, the outdoor unit's fans may
switch to low speed, or one of the fans may stop intermittently.
Hot Start*
The indoor unit prevents cold drafts when heating operation
begins.
The indoor unit fan will not operate or it will operate at a very low
speed until the heat exchanger reaches the set temperature.
Dual Remote Controllers (optional)
An additional remove controller can be added up to the maximum
of two remote controllers. Either remote controller can control
the air conditioner. However, the timer functions cannot be used
at the slave unit.

Group Control

One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same set-
tings.
