• Do not use water hotter than 40˚C or polishing fluid
to clean the unit.
■ Cleaning the Air Filter
(Recommendation:- If the unit is operated in a dusty
environment, clean the filters every two weeks,
continuous use of this dirty filters will reduce cooling
or heating efficiency)
1
Remove dirt using a vacuum cleaner.
2
Wash back of the air filter with water.
3
If badly soiled, wash it with soap or a mild household
detergent.
4
Let it dry and reinstall it.

Remove the air filters
● Triple Deodorizing Filter
• Absorb odours produced by wall paper, construction
material and living environment.
• Reusable.
• Vacuum, place under direct sunlight for 6 hours and
fit it back in place.
(Recommended : every 6 months)
● Catechin Air Purifying Filter
• The filter is coated with catechin to prevent growth
of bacteria and viruses.
• Reusable.
• Vacuum and fit it back in place
(Recommended : every 6 months)
• Recommended to change these filters every 3 years.
Do not reuse damaged filters.
Consult the nearest authorized dealer to purchase a
new filter.
Catechin Air Purifying Filter No.: CZ-SF70P
Triple Deodorizing Filter No.: CZ-SFD72P
• If you operate the air conditioner with dirty filters:-
– Air is not purified
– Cooling capacity decreases
– Foul odour is emitted
■ Pre-season Inspection
● Is the discharged air cold/warm?
Operation is normal if 15 minutes after the start of
operation, the difference between the air intake and
outlet vents temperature is:-
COOL – 8°C or above
HEAT – 14°C or above
● Are the air intake or outlet vents of the indoor or
outdoor units obstructed?
● Are the remote control batteries weak?
If the remote control display appears weak, replace
the batteries.
■ When the Air Conditioner is Not Used
for an Extended Period of Time
1
To dry the internal parts of the indoor unit, operate
the unit for 2 - 3 hours using:-
FAN operation
2
Turn off the power supply and unplug.
Note: If the unit is not switched off by the remote
control, it will start operating when you plug in
(because the unit is equipped with Auto Restart
Control).
3
Remove the remote control batteries.
■ Recommended Inspection
• After used over several seasons, the unit will
become dirty and thus decreases the unit’s
performance. Depending on the operation
conditions, a dirty unit may produce odour and dust
may pollute dehumidification system. Therefore, a
seasonal inspection is recommended in addition to
regular cleaning. (Consult an authorized dealer).
HELPFUL INFORMATION
■ Auto Operation Button
• Raise the front panel and press.
● Automatic Operation
• If the remote control fails to function or has been
misplaced, press the Auto Operation button to start
the Automatic operation.
• The Automatic operation will be activated
immediately once the Auto operation button is
pressed. However, temperature cannot be adjusted
in this operation.
• The power indicator on the indoor unit will blink until
the operation mode is selected automatically.
• To cancel this operation, press once more.
■ Auto Restart Control
• If there is a power failure, operation will be
automatically restarted under the previous operation
mode and airflow direction when power is resumed.
(When the operation is not stopped by remote
control).
• If you do not want the unit to restart automatically
when power is resumed, switch off the power
supply.
• If you do not require Auto Restart Control, consult
your dealer.
• Auto Restart Control is not available when Timer
Mode is set.
• When the operation restarts, the outdoor unit will
operate only after 3~4 minutes.
■ Timer Setting
• When power failure occurs, the timer setting will be
cancelled. Once power is resumed, reset the timer.
■ Thunder and Lightning
• This air conditioner is equipped with a built-in surge
protective device. However, in order to further
protect your air conditioner from being damaged by
abnormally strong lightning activity, you may switch
off the main power supply and unplug from power
socket.
■ Voltage fluctuation
• The outdoor unit stops operation frequently due to a
fluctuation in the voltage. Consult your dealer.
ENERGY SAVING AND OPERATION
HINTS
Here are some useful tips for optimum performance
and cost-effective operation.
■ Setting the Temperature
• Approximately 10% of electricity can be saved.
• Set the temperature higher or lower than the
desired temperature.
Cooling Operation : 1°C higher
Heating Operation : 2°C lower
■ Air Filters and Air Purifying Filters
• Clean the air filters every 2 weeks and the Air
Purifying Filters every 6 months.
• Dirty filters may reduces cooling or heating
efficiency.
■ Keep All Doors and Windows Closed
• Otherwise, cooling or heating performance will be
reduced and electricity cost is wasted.
■ Outdoor Unit
• Do not block the air outlet vents. Otherwise, it will
lower the cooling or heating performance.
■ Timer Mode
• To prevent wastage of electricity, use Timer when
going out.
■ Avoid Direct Sunlight
• Keep curtains or drapes closed to avoid direct
sunlight during cooling operation.

TROUBLESHOOTING
Before calling your dealer, refer to the checklist
• The unit does not operate
• The unit does not cool or heat effectively
• The unit does not receive remote control signals, or
the remote control display is weak or non-existent
• Air is not discharged immediately
• Operation stops suddenly
• Fog is blowing out from the unit
• There is a noise
• The outdoor unit gives off water and steam
Problem?
Problem?
Check
• Has a circuit breaker been tripped or a fuse blown?
• Is the power supply plug disconnected from the outlet?
• Is the Timer being used correctly?
• Has the temperature been set correctly?
• Are the air filters dirty?
• Are the air intake or outlet vents blocked?
• Are all the windows and doors closed?
* Measure the temperature difference. Operation is
normal if, 15 minutes after the start of operation,
the temperature difference between the air intake
and outlet vents is 8°C or above for cooling and
14°C or above for heating.
• Are the batteries weak?
• Have the batteries been inserted with the e and r poles
in the correct position?
Reason
•
At Cooling • Soft Dry (auto Fan Speed)
Air will not be discharged for approximately 40 seconds.
The unit is designed to prevent tobacco, cooking and body
odors from being discharged together with the cool air.
• At Heating (POWER LED blinks)
This is to prevent cold air from blowing out. Please wait.
• At Cooling • Soft Dry (auto Fan Speed)
The indoor fan repeatedly stops for 80 seconds and
operates for 20 seconds to check the indoor temperature.
Whenever the temperature reaches the setting
temperature, operation starts again.
• At Heating (POWER LED blinks)
When the outdoor temperature is low and humidity is high,
frost accumulates on the outdoor unit. The POWER LED
blinks when the unit is melting the frost. (Please wait as
defrosting may take up to 10 minutes.)
• This occurs when the airflow from the air conditioner cools
the room.
• A ‘passt’ sound is heard during defrosting or when the air
conditioner operation has been stopped. This is caused by
the refrigerant inside the air conditioner flowing in the
opposite direction.
• The air conditioner will expand or contract due to changes
in temperature, causing a cracking sound.
• The sound of water flowing is caused by the refrigerant
flowing inside the unit.
• When defrosting, the frost melts and changes to water
and steam.

■ Call the Dealer Immediately
If the following conditions occur, turn off and unplug the
main power supply, and then call the dealer immediately.
• Abnormal noise is heard during operation.
• Water or foreign material gets into the remote
control by mistake.
• Water leak from the indoor unit.
• Switches or buttons do not operate properly.
• Circuit breaker trips or fuse blows frequently.
•
