Features
Protection of the air conditioner
Compressor protection
• The compressor can't restart for 3 minutes
after it stops.
Anti-cold air (or Warm-Start mode)
• The unit is prevented from blowing cold air in
HEAT mode, when the indoor heat exchanger
is in one of the following three situations and
the set temperature has not been reached.
A) Briey at startup cycle of the compressor.
B) During defrosting.
C) Under low temperature heating.
• The indoor or outdoor fans stop running when
defrosting.
Defrosting (Heat Mode)
• Frost may be generated on the outdoor heat
exchanger when outdoor temperature is
low and humidity is high resulting in lower
heating eciency of the air conditioner.
• During this condition air conditioner will enter
into defrost mode automatically.
• The time to defrost may vary from 4 to 10
minutes according to the outdoor temperature
and the amount of frost buildup on the
outdoor unit.
• System will revert back to heat model at the
termination of the defrost cycle.
Auto-Restart
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 enables, the unit will restart automatically
using the last memorized settings.
A white mist blown out from the indoor unit
• A white mist may generate due to a large
temperature dierence between air inlet and
air outlet on COOL mode in an indoor
environment that has a high relative humidity.
• A white mist may generate due to moisture
generated from defrosting process when the
air conditioner restarts in HEAT mode
operation after defrosting.
Certain sounds from the air conditioner
• You may hear a low hissing sound when the
compressor is running or has just stopped
running. This sound is the sound of the
refrigerant owing or coming to a stop.
• You can also hear a low "squeak" sound when
the compressor is running or has just stopped
running. This is caused by heat expansion and
cold contraction of the plastic parts in the unit
when the temperature is changing.
• A noise may be heard due to louver restoring
to its original position when power is rst
turned on.
Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner
has not been used for a long time or during rst
use of the unit.
A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving o smells
permeated from building materials, from furniture,
chemicals used around or cigarette smoke.
NOTE: For multi-split type air conditioner, one outdoor unit can match dierent types of indoor
units. So all the pictures in this manual are for explanatory purpose only. Your air conditioner may
be slightly dierent. Dierent indoor units may be combined. The actual shape shall prevail.
The following pages introduce several kinds of indoor units matching with the outdoor units.

Energy Saving Tips
•
DO NOT
set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
•
DO NOT
place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow toward people and animals.
The air conditioner turns to FAN only mode
from COOL or HEAT mode.
When indoor temperature reaches at the
temperature setting on air conditioner, the
compressor will stop automatically and the air
conditioner switches to FAN only mode. The
compressor will start again when the indoor
temperature rises in COOL mode or falls in
HEAT mode, as compared to the set point.
Condensated mousture may generate on the
surface of the indoor unit when cooling in a high
relative humidity (relative humidity higher than
80%). Adjust the horizontal louver to the maximum
open air outlet position and select HIGH fan speed.
Heating mode
The air conditioner draws in heat from the
outdoor unit and releases it via the indoor unit
during heating operation. 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 can't be achieved by the air
conditioner, a supplementary heating device
must be used under extreme conditions.
Lightning or external electronic interferences
nearby may cause the unit to malfunction.
Disconnect the unit from the power and then
re-connect to clear the cause. Push the
ON/OFF button on the remote controller to
restart operation.
Closing the curtains while heating also
helps keep the heat in
Doors and windows should be kept
closed

Operation mode selection
Maintenance
While simultaneously operating two indoor units
or more, make sure the operation modes will not
conict with each other. The heat mode claims
precedence over all other modes. If the rst unit
intially started to operate under heat mode, the
other units can operate under heat mode only.
For example: If the rst unit intially started to
operate under cool (or fan) mode, the other units
can operate under any mode except heat. If one
of the units switches to heat mode, the other
operating units will stop operation and diplay ”--”
(For the units with display LED) or the Auto and
Operation indication light ash rapidly, the
Defrost indication light turns o, the Timer
indication light remains on (For the units
without display LED), or the Defrost and
Alarm indication light (if applicable) illuminate,
the Operation indication light ashes rapidly
and the Timer indication light turns o ( For the
Floor and standing type).
If you plan to keep the system idle for a long time,
perform the following:
1. Clean the indoor unit and air lter.
2. Select FAN only mode, let the indoor fan run
for a while to dry the inside of the unit.
3. Disconnect the power supply and remove
battery from the remote control.
4. Check components of the outdoor unit
periodically. Contact your installer 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 the dust
accumulated on rear air intake grille, in order to
avoid the dust blowing out 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 airconditioner has not been used for a long
time.
Suggestion: For the systems with an Electric
Heater, when the outside ambient
temperature is below 0°C (32°F), we strongly
recommend you to keep the machine plugged
in order to guarantee smoothl restart.
Optimal operation
To achieve optimal performance, please note the
following:
• Adjust the air ow direction correctly so that it
is notdirected on people or pets.
• Adjust the temperature to achieve the highest
comfort level. Do not adjust the unit to
excessive temperature levels.
• Close doors and windows on COOL or HEAT
modes, or performance may be reduced.
• Use TIMER ON button on the remote controller
to select a time you want to start your air
conditioner.
• Do not put any object near 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 per formance may be
reduced.
• Do not operate unit with horizontal louver in
closed position.
NOTE: Before you clean the air conditioner, be
sure to switch the power o by turning OFF the
circuit breaker feeding the system.

Troubleshooting
CAUTIONS
If one of the following conditions occurs, switch o the power supply immediately and contact
your installer 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.
• The indoor unit leaks.
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.
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
anti-cold (warm-start) function 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 on 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 brief discharge of 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 water 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 dierent sounds based on its current operating mode.
