• During the Wind-Free Cooling operation, the cold air may
be intermittently weakened depending on the temperature
and humidity in the room. But the Wind-Free air currents are
maintained and the weakened cold air is immediately recovered,
consequently keeping the room comfortable. (During the Wind-
Free Cooling operation, the air flow blades may open to control
the indoor air currents smoothly, depending on the installation
settings. In this case, as soon as the indoor temperature and
humidity change, the air flow blades are closed and the Wind-
Free Cooling operation restarts. For more information on the

• While the defrost function is running, the indoor unit provides no
breeze to prevent cold wind.
• If the outdoor temperature is low and the humidity is high while the
Heat mode is running, the heating performance of the air conditioner
may decrease due to frost and ice that formed on the outdoor heat
exchanger. When this condition happens, the air conditioner runs the
defrost function for about 5 to 12 minutes to remove the frost and ice,
and water steam is released from the outdoor unit.

• Under the installation of both A2A (Air-To-Air type air conditioner) and A2W (Air-To-Water type hydro
unit) at the same time, our outdoor machine can supply its full capacity to the operating indoor
machines (including A2A or A2W). If there are simultaneous operating demands from many A2A
machines with A2W, the priority of controlling the outdoor machine (ex: compressor frequency) will be
given to A2A, because of their fast response for use’s comfort. Only the remaining capacity of outdoor
machine will be given to A2W during A2A’s normal operation. In this case, it might take very long time
for A2W heating, so the outdoor machine will alternate the controlling priorities between A2A and A2W
with time basis.
• Priority maximum operation time (at FSV #5033=0): FSV #5031 (Default 30 min., Range 10 ~ 90 min.),
After elapsing A2A maximum time, the outdoor machine will operate only for A2W to speed up the A2W’s
heating/cooling performance, even though there are A2A’s continuous operation demands.
• Non priority minimum operation time (at FSV #5033=0): FSV #5032(Default 5 min., Range 3 ~ 60 min.),
in this minimum time, the outdoor machine will operate only for A2W, even though there are no more
A2W’s continuous operation demands.

Cleaning and Maintenance
1
Dry the air conditioner thoroughly by operating in Fan mode for 3 to 4 hours and disconnect the power
plug. There may be internal damage if moisture is left in components.
2
Before using the air conditioner again, dry the inner components of the air conditioner again by running
in Fan mode for 3 to 4 hours. This helps remove odours that may have generated from dampness.
Periodical checks
Refer to the following chart to maintain the air conditioner properly.
Type Description Monthly
Every 4
months
Once a
year
Indoor unit
Clean the air filter (1).
Clean the condensate drain pan (2).
Thoroughly clean the heat exchanger (2).
Clean the condensate drain pipe (2).
Replace the remote control batteries (1).
Outdoor unit
Clean the heat exchanger on the outside of
the unit (2).
Clean the heat exchanger on the inside of the

Clean the electric components with jets of
air (2).
Verify that all the electric components are
firmly tightened (2).
Clean the fan (2).
Verify that all the fan assembly is firmly
tightened (2).
Clean the condensate drain pan (2).
NOTE
• The checks and maintenance operations described above are essential to guarantee the efficiency of the
air conditioner. The frequency of these operations may vary depending on the characteristics of the area,
the amount of dust, etc.
(1) The above mentioned operations should be performed more frequently if the area of installation is
very dusty.
(2) These operations must always be performed by qualified personnel. For more detailed information,
refer to Installation Manual.
If the air conditioner will not be used for an extended period of time, dry the air conditioner to maintain in
best conditions.

Internal protections via the unit control system
This internal protection operates if an internal fault occurs in the air conditioner.
Type Description
Against cold air The internal fan will be off against cold air when the heat pump is heating.
De-ice cycle The internal fan will be off against cold air when the heat pump is heating.
Protect compressor
The air conditioner does not start operating immediately to protect the
compressor of the outdoor unit after it has been started.
NOTE
• If the heat pump is operating in Heat mode, the de-ice cycle is actuated to remove frost from an outdoor
unit that may have deposited at low temperatures.
• The internal fan is switched off automatically and restarted only after the de-ice cycle is completed.
• When the de-ice cycle is operating,it may generate strange sound. It is normal operation for product
safety.

Problem Solution
The air conditioner does not
operate immediately after it
has been restarted.
• Because of the protective mechanism, the appliance does not
start operating immediately to keep the unit from overloading.
The air conditioner will start in 3 minutes.
The air conditioner does not
work at all.
• Check that the power plug is properly connected. Insert the power
plug into the wall socket correctly.
• Check if the circuit breaker is switched off.
• Check if there is a power failure.
• Check your fuse. Make sure it is not blown out.
The temperature does not
change.
• Check if you selected Fan mode.
Press the button on the remote control to select another
mode.
The cool (or warm) air does
not come out of the air
conditioner.
• Check if the set temperature is higher (lower) than the current
temperature. Press the
or button on the remote control
to change the set temperature. Press the Temperature or
button to increase or decrease the temperature.
• Check if the air filter is blocked by dirt. Clean the air filter every
two weeks.
• Check if the air conditioner has just been turned on. If so, wait for
3 minutes.
The fan speed does not
change.
• Check if you selected Auto or Dry mode.
The air conditioner automatically adjusts the fan speed to Auto in
Auto/Dry mode.
Timer function is not set.
• Check if you press the
and button on the remote control
after you have set the time.
Odours permeate in the room
during operation.
• Check if the appliance is running in a smoky area or if there is a
smell entering from outside. Operate the air conditioner in Fan
mode or open the windows to air out the room.
Refer to the following chart if the air conditioner operates abnormally. This may save time and unnecessary
expenses.

Problem Solution
The air conditioner makes a
bubbling sound.
• A bubbling sound may be heard when the refrigerant is circulating
through the compressor. Let the air conditioner operate in the
selected mode.
Water is dripping from the air
flow blades.
• Check if the air conditioner has been cooling for an extended
period of time with the air flow blades pointed downwards.
Condensation may generate due to the difference in temperature.
Remote control is not
working.
• Check if your batteries are depleted.
• Make sure batteries are correctly installed.
• Make sure nothing is blocking your remote control sensor.
• Check that there are strong lighting apparatus near the air
conditioner. Strong light that comes from fluorescent bulbs or
neon signs may interrupt the electric waves.
Operation Ranges
The table below indicates the temperature and humidity ranges the air conditioner can be operated within.
Refer to the table for efficient use.

• The standardized temperature for heating is 7 ˚C. If the outdoor temperature drops to 0 ˚C or below, the
heating capacity can be reduced depending on the temperature condition.
• If the cooling operation is used at over 32˚C (indoor temperature), it does not cool at its full capacity.
