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 insufficient
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 recir-
culating air throughout the room, with the result that some
time may be required after first 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.
The wired remote controller option is required to use the following function (**).
Dual Remote Controllers (optional)**
An additional remote controller can be added up to the maximum of 2 remote controllers. Either remote controller can control the
air conditioner. However, the timer functions cannot be used at the secondary unit.
Group Control**
1 remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same settings.
AUTO Restart
In Event of Power Interruption
● Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
● Should a power failure occur during TIMER operation, the
timer will be reset and the unit will begin (or stop) operat-
ing under the new timer setting. In this event, the TIMER
indicator lamp will flash.
Notices
Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
* ● During use of the heating mode, the outdoor unit will occa-
sionally commence the defrost operation for brief periods.
During the defrosting operation, if the user sets the indoor
unit for heating again, the defrosting mode will continue,
and the heating operation will begin after completion of
defrosting, with the result that some time may be required
before warm air is emitted.
Microcomputer-controlled Automatic Defrosting*
● When using the heating mode under conditions of low out-
door 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. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate
briefly (for about 4 to 15 minutes).
During automatic defrosting operation, the OPERATION
indicator lamp will flash.
Low Ambient Cooling*
● When the outdoor temperature drops, the outdoor unit's
fans may switch to low speed.
Hot Start (for heating)*
● 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.
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the
air conditioner to malfunction. In this event, temporarily
disconnect the power supply plug, reconnect it, and then
use the remote controller to resume operation.
* ● During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that coolant is
circulated through the indoor unit even when it is stopped;
it is not a malfunction.
