ADDITIONAL NOTES ON

OPERATION

OPERATING TEMPERATURE RANGE

BEFORE CALLING FOR

SERVICE

The following conditions do not denote equip-

ment 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 internal mechanisms. 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 sent out from the unit.

CRACKING NOISE

The unit may produce a cracking noise. This sound

is generated by the friction of the front panel and

other components expanding or connecting due to a

temperature change.

A LOW BUZZING NOISE EMITTED

This is a sound emitted when the unit is generating

Plasmacluster ions.

SWISHING NOISE

The soft, swishing noise is the sound of the refrigerant

ﬂ owing inside the unit.

WATER VAPOUR

• In the COOL and DRY operation, water vapour

can sometimes be seen at the air outlet due to the

difference between the room air temperature and

the air discharged by the unit.

• In the HEAT 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.

If the unit appears to be malfunctioning, check the

following points before calling for service.

IF THE UNIT FAILS TO OPERATE

Check to see if the circuit breaker has tripped or the

fuse has blown.

IF THE UNIT FAILS TO COOL (OR HEAT) 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 proper setting.

• Make sure windows and doors are closed tightly.

• A large number of people in the room can prevent

the unit from achieving the desired temperature.

• Check whether any heat-generating appliances are

operating in the room.

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 with the polarities properly aligned.

Please call for service when OPERATION lamp,

TIMER lamp and/or PLASMACLUSTER lamp on

the unit blink.

WHEN POWER FAILURE OCCURS

This air conditioner has a memory function to store

settings when a power failure occurs.

After power recovery, the unit will automatically re-

start 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 efficiency 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.
