Explanation of heating operation
Defrost operation
■As the frost on the coil of an outdoorunit increase,
heating effect decreases and the system goes into
DEFROST OPERATION.
■The fan operation stops and the DEFROST lamp of
the indoorunit goes on.
After6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
Heating capacity and outdoor air temperature
■Heating capacity drops as outdoorairtemperature
lowers.If feeling cold, use anotherheaterat the same
time as this airconditioner.
■Hot airis circulated to warm the room.It will take
some time from when the airconditioneris first
started until the entire room becomes warm.The
internal fan automatically turns at low speed until the
airconditionerreaches a certain temperature on the

DISPOSAL REQUIREMENTS
Batteries supplied withthe remote controller
are marked withthis symbol.
This means that the batteries shall not be
mixed withunsorted household waste.
If a chemical symbol is printed beneaththe symbol, this
chemical symbol means that the battery contains a
heavy metal above a certain concentration.Possible
chemical symbols are:
■Pb: lead (>0.004%)
Waste batteries must be treated at a specialized
treatment facility forre-use.
By ensuring waste batteries are disposed of correctly,
you will help to prevent potential negative consequences
forthe environment and human health.
Example Reason
The remote controller
indicates "U4" and "U5",
the unit stops.Within
several minutes the unit
restarts.
Due to electrical noise
otherthan that from the
airconditioner, the
communication between
the units is cut off and the
unit stops.
When the noise is gone,
the unit automatically
restarts.
Example Reason
The indoorunit makes a
"PEEE" receiving sound.
When operation
changeoveris under
control, the control is set
to the mode that cannot
be carried out.
Example Reason
Even if the airflow rate
adjusting button is
pressed, the airflow rate
does not change.
When the room
temperature reaches the
indoorunit set
temperature, the outdoor
unit stops and the airflow
rate of indoorunit drops
to the minimum.
This is to avoid the cold
airfrom getting in contact
withthe people in the
room.
Example Reason
The remote controller
indication and the air
discharge direction is not
the same.
Airdischarge direction
swing is impossible.
Because it is controlled
by microcomputer. Refer
to "AIR FLOW
DIRECTION ADJUST" on
page 5.
Example Reason
Even if the unit is
operated, only the
operation indication
shows, oreven if the
indication shows, soon
after, the indication other
than that foroperation
disappears.
The corresponding indoor
unit is that formulti-
system and the remote
controlleris set to the
multi-system.
Example Reason
When the remote
controllerbutton is
pressed.
The battery is dead.
Example Reason
It is in program dry
operation.
The program dry
operation is an operation
mode trying to keep the
room temperature
constant as muchas
possible.Referto
"Cooling, Heating,
Automatic, Fan and
Program dry operation"
on page 4.
