HEATING OPERATION
PREPARATION OF HEATING
• Heat pump type
Heat pump type heating applies the mechanism that draws the heat from the outside air to warm up the room by means of the refrigerant.
• Defrost operation
During heating with a heat pump type air conditioner, frost will be formed on the outdoor unit if the temperature outside the room drops. If left alone, the
heating efficiency decreases. In order to deal with this, the operation is automatically switched to defrost operation to remove the frost. During the period,
the air ow of indoor/outdoor unit is stopped and “heating defrost” is displayed.
• Outer air temperature and heating capacity
The heating efficiency of heat pump type air conditioner decreases as the outside temperature becomes lower. If the capacity of air conditioner for heating
is not sufficient, please use other heating device.
• Time required until the room temperature increases
A heat type air conditioner circulates warm air to warm the entire room, so it takes a while to rise up the room temperature. It is recommended to start
operation earlier on a very cold day.
• When room temperature adjusting device operates during heating
If room temperature rises and the room temperature adjusting device is activated, the air ow becomes automatically low. When the room temperature
drops, it switched back automatically to the normal operation.
“ (PREPARATION OF HEATING)” is displayed in the remote control display area in the following cases.
For wireless devices, the run/check display lamp on the main body display unit will ash green.
Setting temperature and preparation of heating are displayed on the wired remote control.
• At Starting Heating Operation
In order to prevent cool air from blowing out, the air ow into the room may be stopped depending on the room temperature at the
start of heating operation. please wait for a while and the operation automatically switches to the normal heating operation.
• At defrost operation (during heating operation)
When frost may easily formed on the outdoor unit, the heating operation automatically is stopped (both indoor/outdoor unit
stop fan operation) for approximately 5 to 10 minutes per hour and defrosting is operated. After the defrosting is complete, the
operation automatically switches back to the normal operation.
CASES WHEN “ (PREPARATION OF HEATING)” IS DISPLAYED
NOTICE
An auto restart function, which is disabled at the factory setting, is applicable to the remote control. Consult your dealer.
What is auto restart
• When a power failure occurs or the power supply is turned off, the function allows the system to automatically resume operation with the remote control
setting made set before the power failure when the power supply recovers. If the system is stopped before power failure it remains stopped after the power
recover.
• Note that in the following cases it is needed to set again with the remote control.
1
Timer setting is cancelled. But the sleep timer recovers after power failure recovers. When recovering from a power failure, holiday setting will override
the weekly timer setting. And time setting returns to default. To return to original setting, after time setting, execute “holiday cancel”.
2
Louver stops at the horizontal position.
CAUTION
Make sure to stop the operation before turning off the power supply when the auto restart function is enabled. (If the power supply is turned off while the
system is operating, the indoor unit fan will start immediately when the power supply is turned on. In addition, the outdoor unit starts operating 3 minutes
after the power supply is turned on.)
AUTO RESTART <WIRED REMOTE CONTROL>
TROUBLE SHOOTING
The phenomena mentioned below is not malfunction.
Slapping sounds are heard. These sounds are generated when plastic components are expanded or shrunk by the heat and rubbed with
each other.
Hissing sounds are heard
when the operation is
stopped or during defrost
operation.
These sounds are generated when the refrigerant valve inside the air conditioning system is activated.
The air conditioner starts
operation automatically as
soon as the power supply is
turned on.
In case the automatic restart function is enabled, and when the power supply recovers, the system restarts the
operation automatically as same condition as before power supply is cut.

POOR COOLING OR HEATING POOR COOLING
If, after checking the items above, the air conditioner still does not operate normally or in the next cases, stop operating and contact your dealer.
• If the fuse and breaker blow frequently. • If water drips at cooling/dehumidifying operation. • If the operation or operation noise is abnormal.
• If the check indicator light ashes.
The phenomena mentioned below is not malfunction.
NO AIRFLOW AT HEATING
The air conditioning system
sounds as if water is
draining from it.
Sounds of rustling or gurgling may be heard when the operation is started, when the compressor is activated/
deactivated during operation, or when the operation is stopped. These are the sounds of the refrigerant
owing through the system.
Sounds of rustling or
gurgling may be heard from
a stopped indoor unit.
These sounds can be heard when the air conditioning system is performing automatic control.
The supply air from the
indoor unit smells bad.
The supply air from the indoor unit may smell bad if the smell of cigarettes, cosmetics and/or furniture has
saturated the air conditioning system.
White vapor is generated
from the indoor unit during
operation.
White vapor may be generated during operation if the system is used in environment where oils and fats are
frequently used, such as in restaurants. In this case, consult the dealer and clean the heat exchanger.
The operation switched to
fan operation during cooling
operation.
The operation may switch to fan operation automatically in order to avoid frost being built up on the surface of
the heat exchanger. The operation will soon return to cooling operation.
The indoor fan does
not stop even when the
operation is stopped in
heating mode.
The indoor unit fan may continue operating for 40 seconds in order to remove remaining heat in the indoor
unit.
CAUTION
Do not turn off the power supply until the fan stops.
The air conditioning system
cannot start operating again
immediately after stopping.
During the rst 3 minutes after stopping operation, it is not possible to perform cooling, dehumidifying or
heating operation even if the ON/OFF button is pressed to indicate “operation.” This is because a circuit for
protecting the compressor is activated (the fan is operating during this period).
No air comes out during
dehumidifying operation.
The air ow volume cannot
be changed.
During dehumidifying operation, the fan speed is automatically controlled in low speed/stop cycle in order to
avoid both drastic temperature drop and humidity rise.
The swing louver moves
without any operation.
The swing louver automatically swings twice when the power supply switch is turned on. This is not a trouble.
The louver also moves automatically to the horizontal position when “PREPARATION OF HEATING” is
displayed.
The outdoor unit discharges
water or steam during
heating operation.
Water or steam is discharge during defrosting operation which removes frost built up on the surface of the
heat exchanger in the outdoor unit in heating mode.
The outdoor unit fan is not
running even when the
system is in operation.
The fan speed is automatically controlled according to the ambient temperature. It may be stopped in high
ambient temperature in case of heating, and in low ambient temperature in case of coding. Also, the fan is
stopped during defrosting operation.
CAUTION
The fan will suddenly begin to operate even if it is stopped. Do not insert nger and/or stick.
The operation switched to
fan operation during cooling
operation.(in case of FDFW
type)
In case the relative humidity is 73% or higher, the operation may alternate between fan operation and cooling
operation even though the thermostat has not been activated. The objective of this operation mode is to
prevent condensate dew formation and dew dropping from indoor unit air supply port.
The operation mode cannot
be selected (in case of the
heat recovery system KXR).
When operation mode is set to the main and sub indoor unit during the heat recovery system KXR, operation
mode of the sub unit cannot be selected.(In this case, the system conforms to operation mode of the main
unit.)
The airflow becomes weak
if the operation mode is
changed during operation
(in case of the heat recovery
system KXR).
When you switch the operation mode from Cool to Heat or from Heat to Cool during operation, the airflow
becomes weak for 3 minutes.

NOTICE
Please observe the following points in order to use the air conditioner in a safe and comfortable manner.
Make sure to request your dealer for installation, and do not attempt to do by yourself.
Is the system installed in a well-ventilated place?
Are there any obstacles? If so, it leads to the decrease of the efficiency and the increase of operation noise.
Avoid the place where cool/warm air and operation noise cause problems to your neighbors.
INSTALLATION LOCATION
Normally the efficiency of the air conditioning system will become lower after a while, because dirt accumulates inside the system. This occurs gradually in
around 3 years of use, depending on the condition of use and surrounding environment. It is thus necessary to conduct inspection maintenance in addition
to regular maintenance. We recommend you to consult the dealer from whom you purchased the system and make a contract for periodical inspection.
