Features
Protections of the air conditioner:
a. Compressor Protection
• The compressor will not restart for 3 minutes
following an o cycle or for initial start.
b. Draft-Prevention Mode (Warm-Start Mode)
• The indoor unit fan is designed to not start in
HEAT mode, when the indoor heat exchanger
is in one of the following four situations, and
the set temperature has not been reached:
A) When heating has just begun.
B) During defrosting.
C) Low temperature heating.
D) Indoor heat exchanger is not warm yet.
• The indoor or outdoor fans stop running when
defrosting, in order to speed up the defrost cycle.
c. Defrosting (automatically handled as needed)
• Frost will accumulate on the outdoor unit coils
during a heat cycle when outdoor temperature
is low and humidity is high, resulting in lowered
heating eciency and performance.
• Under these conditions, the air conditioner will
stop heating operations and will automatically
begin defrosting for a brief period.
• The time to defrost may vary from 4 to 10
minutes, depending the outdoor temperature
and the amount of frost buildup on the
outdoor unit heat exchangers.
d. Auto-Restart (can be user deactivated)
In case of power failure, the system will
immediately stop. When power returns, the
operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on the
remote control. If the system has the auto-restart
function enabled, the unit will restart with the
same settings without any action (by default).
White mist may emerge from the indoor unit
• White mist may be generated, due to a large
temperature dierence between the air inlet and
air outlet, in COOL mode in places with high
relative humidity.
• White mist may also be generated due to moisture
created in the defrosting process, when the air
conditioner restarts in HEAT mode operation
after defrosting.
Noise coming from your air conditioner
• You may notice a low hissing sound when the
compressor is running, or has just stopped
running. This sound is the eect of the
refrigerant owing or coming to a stop.
• You may also hear a low "squeaking" sound
when the compressor is running, or has just
stopped running. This is caused by heat
expansion and cold contraction of plastic
parts in the unit due to changing
temperatures.
• A noise may be heard due to the louver
restoring itself to its original position when
the power is rst turned on.
Dust blowing out from the indoor unit.
This is happens when the air conditioner has not
been used for a long time or during its rst use.
Smell emitting from the indoor unit.
This is caused by the indoor unit giving o smells
permeated from building materials, furniture,or
smoke.
NOTE: For multi-split type air conditioners, one outdoor unit can be matched with other types of
indoor units of various dierent styles, as well as those with similar capacities, within the same system.
Your system may be slightly dierent in shape. The following pages introduce several kinds
of indoor units that can be matched with the multi zone outdoor units.

Energy Saving Tips
•
DO NOT
set the unit to excessive temperature levels.
• While cooling, close the curtains in order to avoid direct sunlight.
• Doors and windows should be kept closed so as to keep cool or warm air in the room.
•
DO NOT
place objects near the air inlet or outlet of the unit.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you do not plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks.
• Adjust louvers properly and avoid direct airflow toward people, animals, or plants.
The air conditioner turns to FAN-ONLY
mode from COOL or HEAT (for cooling and
heating models only) mode.
When the indoor temperature reaches the set
temperature setting, the compressor will stop
automatically, and the air conditioner shifts to
FAN-ONLY mode. The compressor will start again
when the indoor temperature rises on COOL
mode, or falls on HEAT mode, to the set point.
Droplets of water may form on the surface of
the indoor unit when cooling during relatively
high humidity (dened as higher than 80%).
Adjust the horizontal louver to the maximum air
outlet position, and select HIGH fan speed.
Heating mode (for cooling and heating
models only)
The air conditioner draws in heat from the
outdoor unit and releases it via the indoor unit
during heating. When the outdoor temperature
falls, heat drawn in by the air conditioner
decreases accordingly. At the same time, heat
loading of the air conditioner increases due to
larger dierence between indoor and outdoor
temperature. If a comfortable temperature
cannot be achieved with the air conditioner
alone, it is recommended that you use a
supplementary heating device.
Lightning or a wireless devices operating
nearby may cause the unit to malfunction.
Disconnect the unit from its power source and
then re-connect the unit with the power source
again. Push the ON/OFF button on the remote
controller to restart operations.
Closing curtains during heating also
helps to keep the heat in
Doors and windows should be kept
closed as much as possible
Inverter models will adjust their refrigeration
capacities automatically based on actual room
loads. Fan will keep running during operation.
Manual Operations
And Maintenance

Operation mode selection
Maintenance
While two or more indoor units are
simultaneously operating, make sure the “modes”
do not conict with each other. The heat mode
claims precedence over all other modes. If the
unit initially begins operation in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit intially started operating under
COOL (or FAN) mode, the other units can operate
under any mode except HEAT. If one of the units is
set in HEAT mode, the other running units will
stop operation and diplay ”P5” (for units with
display window only) or the auto and operation
indication lights will ash rapidly, the defrost
indication light will turn o, and the timer
indication light will remain on (for units without
a display window). Alternatively, the defrost and
alarm indication light (if applicable) will light up,
or the operation indication light will ash rapidly,
and the timer indication light will turn o (for
the oor and standing type).
If you plan on leaving the unit idle for a long time,
perform the following tasks:
1. Clean the indoor unit and air lter.
2. Select FAN-ONLY mode and let the indoor fan
run for some time to dry the inside of the unit.
3. Disconnect the power supply and remove the
battery from the remote control.
4. Check the components of the outdoor unit
periodically. Contact a local dealer or a
customer service center if the unit requires
servicing.
When the air conditioner is to be used
again:
• Use a dry cloth to wipe o any dust that has
accumulated on the rear air intake grille, in order
to avoid the dust being dispersed from the
indoor unit.
• Check that the wiring is not broken o or
disconnected.
• Check that the air lter is installed.
• Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a long
time.
For units that feature an outdoor electrical heater,
when the outdoor ambient temperature is
below 0°C (32°F), it is strongly recommended
for you to keep the machine energized so as
to keep it warm for a smoother restarting operation.
Optimal operation
To achieve optimal performance, please note the
following:
• Adjust the direction of the air ow so that it is
not blowing directly onto any people.
• Adjust the temperature to achieve the highest
possible level of comfort. Do not adjust the
unit to extreme temperature levels.
• Close doors and windows in COOL mode or
HEAT mode.
• Use the TIMER ON button on the remote
controller to select a time that you want your
air conditioner to start.
• Do not place any objects near the air inlet or air
outlet, as the eciency of the air conditioner
may be reduced, and the air conditioner may
stop running.
• Clean the air lter periodically, otherwise
cooling or heating performance may be
reduced, and the heat exchanger can get clogged.
• Do not operate unit with the horizontal louver in
a closed position.
NOTE: Before you clean the air conditioner, be
sure to switch o the unit and disconnect the
power supply breaker.

Troubleshooting
CAUTIONS
If one of the following conditions occur, switch o the power supply immediately and contact
your installer or dealer for further assistance.
• The operation light continues to flash rapidly after the unit has been restarted.
• The remote control buttons do not work.
• The unit continually trips fuses or circuit breakers.
• A foreign object or water enters the air conditioner.
• Any other abnormal situation.
Common Problems
The following symptoms are not a malfunction and in most situations will not require repairs.
Problem Possible Causes
Unit does not
turn on when
pressing ON/
OFF button
The unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being
turned o, and within 3 minutes of each initial startup.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s
warm-start mode is activated in order to defrost the unit.
In Cooling-Only Models: If the “Fan-Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
The unit changes
from COOL mode
to FAN mode
The unit changes its setting to prevent frost from forming onto the unit. Once
the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns o the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits white mist
In humid regions, a large temperature dierence between the room’s air and
the conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
The indoor unit
makes noises
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped
running or is defrosting. This noise is normal and is caused by the refrigerant
gas stopping or changing direction.
The outdoor unit
makes noises
The unit will make certain expected sounds based on its operating mode.
Troubleshooting

Troubleshooting
Problem Possible Causes
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which
will be emitted when the unit is turned on. This can be mitigated by covering
the unit during long periods of inactivity.
The unit emits a
foul odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.), which will be emitted during operation.
The unit’s filters have become dirty or moldy, and should be cleaned.
The fan of the
outdoor unit
does not operate
During defrosting operations, the fan of the outdoor unit is stop-controlled to
optimize the defrosting operation. Otherwise, check for blockage by ice/snow.
