GENERAL
The high wall fan coil unit provides quiet, maximum comfort. In
addition to cooling and/.
IMPORTANT: The high wall fan coil unit should be installed by
authorized personnel only; using approved tubing and accessories.
If technical assistance, service or repair is needed, contact the
installer.
The high wall fan coil unit can be set up and operated from the
remote control (provided). If the remote is misplaced, the system
can be operated from the “Auto” setting on the unit.
Operating Mo
five operating modes.
SFan only
SAuto
SHeating (heat pump models only)
SCooling
SDehumidification (DRY)
Fan Only
In Fan Only mode, the system filters and circulates room air
without changing room air temperature.
Auto
In Auto mode, the system will automatically cool or heat the room
according to the user--selected set point.
Heating
In Heating mode, the system heats and filters room air.
Cooling
In Cooling mode, the system cools, dries and filters room air.
Dehumidification (DRY)
In Dehumidification mode, the system dries, filters and slightly
cools room air temperature. This mode prioritizes air
dehumidification but it does not take the place of a dehumidifier.
Remote Control
The remote control transmits commands to set up and operate the
system. The control has a window display panel that shows the
current system status. The control can be secured to a surface
when used with the mounting bracket provided.

Symptom 4: Noise of air conditioners cooling
Symptom 4.1: Indoor unit
When humidity is high during cooling operation If the interior of
an indoor unit is extremely contaminated, the temperature
distribution inside a room becomes uneven. It is necessary to
clean the interior of the indoor unit. Ask your dealer for details
on cleaning the unit. This operation requires a qualified service
person.
When the system is changed over to heating operation after
defrost operation Moisture generated by defrost becomes
steam and is exhausted.
A continuous low "shah" sound is heard when the system is in
cooling operation or at a stop.
When the drain pump (optional accessories) is in operation,this
noise is heard.
A "pishi-pishi" squeaking sound is heard when the system stops
after heating operation.
Expansion and contraction of plastic parts caused by
temperature change make this noise.
Symptom 4.2: Indoor unit, outdoor unit
A continuous low hissing sound is heard when the system is in
operation.
This is the sound of refrigerant gas flowing through both indoor
and outdoor units.
A continuous low hissing sound is heard when the system is in
operation.
This is the sound of refrigerant gas flowing through both indoor
and outdoor units.
A hissing sound which is heard at the start or immediately after
stopping operation or defrost operation.
This is the noise of refrigerant caused by flow stop or flow
change.
Symptom 4.3: Outdoor unit
When the tone of operating noise changes.
This noise is caused by the change of frequency.
The operation lamp is flashing rapidly (5Hz).
This lamp is still flashing rapidly after turn off the power and turn
on again. (See in Table 8-1)
Remote controller receives malfunction or the button does not
work well.
A safety device such as a fuse, a breaker frequently actuates.
Obstacles and water enter the unit.
Water leaks from indoor unit.
Other malfunctions.
8. TROUBLESHOOTING
If one of the following malfunctions occur, stop operation, shut
off the power, and contact with your dealer.
If the system does not properly operate except the above
mentioned cases or the above mentioned malfunctions is
evident, investigate the system according to the following
procedures. (See in Table 8-2)
8.1 Troubles and causes of air conditioner
Symptom 5: Dust comes out of the unit
Symptom 6: The units can give off odours
When the unit is used for the first time in a long time.
This is because dust has gotten into the unit.
The unit can absorb the smell of rooms, furniture, cigarettes,
etc., and then emit it again.
Symptom 7: The outdoor unit fan does not spin.
During operation. The speed of the fan is controlled in order to
optimize product operation.
8.2 Troubles and causes of remote controller
Before asking for serving or repairing, check the following points.
(See in Table 8-3)
7. FOLLOWING SYMPTOMS ARE NOT AIR
CONDITIONER TROUBLES
Symptom 1: The system does not operate
Symptom 2: Change into the fan mode during cooling
mode
Symptom 3: White mist comes out of a unit
The air conditioner does not start immediately after the ON/OFF
button on the romote controller is pressed.
If the operation lamp lights, the system is in normal condition.To
prevent overloading of the compressor motor, the air
conditioner starts 3 minutes after it is turned ON.
If the operation lamp and the " PRE-DEF indicator(cooling and
heating type) or fan only indicator(cooling only type)" light, it
means you choose the heating model, When just starting, if the
compressor has not started, the indoor unit appears "anti cold
wind" protection because of its overlow outlet temperature.
In order to prevent the indoor evaporator frosting, the system
will change into fan mode automatically, restore to the cooling
mode after soon.
When the room temperature drops to the set temperature, the
compressor goes off and the indoor unit changes to fan mode;
when the temperature rises up, the compressor starts again. It
is same in the heating mode.
Symptom 3.1: Indoor unit
Symptom 3.2: Indoor unit, outdoor unit
When humidity is high during cooling operation If the interior of
an indoor unit is extremely contaminated, the temperature
distribution inside a room becomes uneven. It is necessary to
clean the interior of the indoor unit. Ask your dealer for details
on cleaning the unit. This operation requires a qualified service

The following should be noticed to ensure economical
operation.
Adjust the air flow louver properly and avoid direct air flow to
room inhabitants.
Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.
Prevent direct sunlight during cooling operation by using
curtains or blinds.
Ventilate often. Extended use requires special attention to
ventilation.
Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room a decrease
in the cooling or heating effect.
Never place objects near the air inlet or the air outlet of the unit.
It may cause effect or stop the operation.
Set the timer .
If you don't plan to use the unit for a long time, please take the
batteries from the remote controller. When the power is on,
some energy will be consumed,even if the air conditioner isn't in
operation. So please disconnect the power to save energy.
Keep the indoor unit and remote controller at least 3.28ft (1m)
away from televisions, radios, stereos, and other similar equipment.
Fail to do so may cause static or distorted pictures.
A dirty air filter reduce cooling or heating efficiency, please
clean it once two weeks.
While the unit is in operation, you can adjust the air flow louver
to change the flow direction and naturalize the room
temperature evenly. Thus you can enjoy it more comfortably.
