SETTING AIR PURIFYING FILTER
TIPS ON SAVING ENERGY
The air purifying filters are packed as
accessory of this unit. During operation, the
fi lters remove dust and tobacco smoke from the
air and discharges clean air.
Take out the air fi lters.

Below are some simple ways to save energy.
SET THE PROPER TEMPERATURE
• Setting to higher or lower than necessary
temperature point will result in increased power
consumption.
BLOCK DIRECT SUNLIGHT AND PREVENT
DRAFTS
• Blocking direct sunlight during cooling operation
will reduce power consumption.
• Close the windows and doors during cooling and
heating operations.
SET PROPER AIR FLOW DIRECTION TO OBTAIN
THE BEST AIR CIRCULATION
KEEP THE FILTER CLEAN TO ENSURE THE
MOST EFFICIENT OPERATION
USE THE TIMER OFF FUNCTION WHEN
POSSIBLE
TURN OFF THE CIRCUIT BREAKER WHEN THE
UNIT IS NOT USED FOR AN EXTENDED PERIOD
OF TIME
• The indoor unit still consumes a small amount of
power when it is not operating.

COOLING
• The built-in protective device may prevent the unit
from operating when used out of this range.
• Condensation may form on the air outlet if the unit
operates continuously in the COOL or DRY mode
when humidity is over 80 percent.
WHEN POWER FAILURE OCCURS
This unit has a memory function to store settings
when a power failure occurs.
After power recovery, the unit will automatically restart in the same settings which were active before
the power failure, except for timer settings.
If the timers were set before a power failure, they
will need to be re-set after power recovery.
PREHEATING FUNCTION
In the HEAT operation, the indoor fan may not start
for two to fi ve minutes after the unit is turned on to
prevent cold air from blowing out of the unit.
DE-ICING FUNCTION
• When ice forms on the heat exchanger in the
outdoor unit during the HEAT operation, an
automatic de-icer provides heat for about 5 to 10
minutes to remove the ice. During de-icing, the
inside and outside fans stop operating.
• After de-icing is completed, the unit automatically
resumes operation in the HEAT mode.
HEATING EFFICIENCY
• The unit employs a heat pump that draws heat
from the outside air and releases it into the room.
The outside air temperature therefore greatly
affects the heating effi ciency .
• If the heating effi ciency is reduced due to low
outside temperatures, use an additional heater.
• It takes time to warm up and heat the entire room
because of the forced air circulation system.

BEFORE CALLING FOR SERVICE
The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the unit. Wait 3 minutes before
operating the unit.
UNIT DOES NOT SEND OUT WARM AIR
The unit is preheating or de-icing.
ODORS
Carpet and furniture odors that entered into the unit
may be recirculated by the unit.
CRACKING NOISE
This sound is generated by the friction of the unit
expanding or connecting due to a temperature
change.
A LOW BUZZING NOISE
This is a sound of the unit generating Plasmacluster
ions.
SWISHING NOISE
The soft, swishing noise is the sound of the
refrigerant fl owing inside the unit.
MIST SEEN AT INDOOR AIR OUTLET
In cooling operation, this is caused by the difference
between the room air temperature and the air
discharged.
Check the following points before calling for
service.
IF THE UNIT FAILS TO OPERATE
Check if the circuit breaker has tripped or the fuse
has blown.
IF THE UNIT FAILS TO HEAT (OR COOL) THE
ROOM EFFECTIVELY
• Check the fi lters. If dirty, clean them.
• Check the outdoor unit to make sure nothing is
blocking the air inlet or outlet.
• Check the thermostat is properly set.
• Make sure windows and doors are closed tightly.
IF THE UNIT FAILS TO RECEIVE THE REMOTE
CONTROL SIGNAL
• Check whether the remote control batteries have
become old and weak.
• Try to send the signal again with the remote
control pointed properly towards the unit’s signal
receiver window.
• Check whether the remote control batteries are
installed properly.
Please call for service when OPERATION lamp,
TIMER lamp and/or PLASMACLUSTER lamp on
the unit blink.
WATER VAPOUR
In heating operation, water vapour may fl ow out of
the outdoor unit during de-icing.
THE OUTDOOR UNIT DOES NOT STOP
After stopping the operation, the outdoor unit will
rotate its fan for about a minute to cool down the
unit.
ODOR EMITTED FROM THE PLASMACLUSTER
AIR OUTLET
This is the smell of ozone generated from
the Plasmacluster Ion generator. The ozone
concentration is very small, posing no adverse
effect on your health. The ozone discharged into the
air rapidly decomposes, and its density in the room
will not increase.
