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 type of heating appliance.
Heat-pump air conditioners heat your entire room by
recirculating 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.
*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 per-
formance.
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
on the remote controller. 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 1 of the fans may stop
intermittently.
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.
Group control cannot be used when using it by the multi
type.
