FEATURES AND FUNCTIONS

INVERTER

At the start of operation, large amount of power is used to

bring the room quickly to the desired temperature. After-

wards, the unit automatically switches to a low power setting

for economic and comfortable operation.

ECONOMY OPERATION

When ECONOMY operation mode is operated, the room

temperature will be little higher than the set-temp under

cooling mode and lower than set-temp under heating

mode. Therefore, the ECONOMY mode is able to save

more energy than other normal mode.

SUPER QUIET OPERATION

When the FAN button is used to select QUIET, the indoor

unit begins super-quiet operation; the indoor unit’s airﬂ ow

is reduced to produce quieter operation.

AUTO CHANGEOVER

The operation mode (cooling, dry, heating) is switched automatically

to maintain the set temperature, and the temperature is kept constant

at all times.

TEMPERATURE SET BACK TIMER

Use this timer function to change the set temperature in

the operation times set for each day of the week. This can

be used together with other timer settings.

REMOVABLE AIR FILTER

The indoor unit’s air ﬁ lter can be removed for easy cleaning

and maintenance.

MILDEW-RESISTANT FILTER

The AIR FILTER has been treated to resist mildew growth,thus

allowing cleaner use and easier care.

CLEANING AND CARE

Cleaning the Air Filter



Before cleaning the unit, be sure to stop the unit and disconnect the power supply.



Turn off the electrical breaker.



A fan operates at high speed inside the unit, and personal injury could result.



When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that

the unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized

service personnel.



When cleaning the unit’s body, do not use water hotter than 104 °F, harsh abrasive cleansers, or volatile agents like

benzene or thinner.



Do not expose the unit body to liquid insecticides or hairsprays.



If the unit will not be operated for a period of 1 month or more, be sure to allow the inner parts of the unit to dry thor-

oughly, in advance, by operating the unit in fan mode for half a day.



Remove the dust from the air ﬁ lters by vacuuming or washing them. After washing, allow the air ﬁ lters to dry thoroughly

in an area protected from sunlight.



Dust can be cleaned from the air ﬁ lter either with a vacuum cleaner, or by washing the ﬁ lter in a solution of mild deter-

gent and warm water. If you wash the ﬁ lter, be sure to allow it to dry thoroughly in a shady place before reinstalling.



If dirt is allowed to accumulate on the air ﬁ lter, air ﬂ ow will be reduced, lowering operating efﬁ ciency and increasing

noise.

CAUTION!

ECONOMY OPERATION

Begin Air Conditioner operation before performing this procedure.

To Use the ECONOMY Operation

Press the ECONOMY button.

The ECONOMY display will light.

ECONOMY operation begins.

To Stop the ECONOMY Operation

Press the ECONOMY button again.

The ECONOMY display will go out.

Normal operation begins.

About ECONOMY Operation

At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation for cooling and

heating.



If the room is not cooled (or heated) well during ECONOMY operation, select normal operation.



During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation

even if ECONOMY operation is selected by pressing the ECONOMY operation button.



When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cool-

ing mode and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy

than other normal mode.



In case of multi-type air conditioner, the ECONOMY operation mode is only available for the set indoor unit.



Can be used if set correctly during installation. Please consult authorized serviceman when using this

function.

TROUBLESHOOTING

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

WARNING!

In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the

electrical breaker, and consult authorized service personnel.

Merely turning off the unit’s power switch will not completely disconnect the unit from the

power source. Always be sure to turn off the electrical breaker to ensure that power is com-

pletely off.

Before requesting service, perform the following checks:

Symptom Problem

See Page

NORMAL

FUNCTION

Doesn’t operate immedi-

ately:



If the unit is stopped and then immediately started again, the

compressor will not operate for about 3 minutes, in order to

prevent fuse blowouts.



Whenever the electrical breaker is turned off then on again, the

protection circuit will operate for about 3 minutes, preventing

unit operation during that period.

—

Noise is heard:



During operation and immediately after stopping the unit, the

sound of water ﬂ owing in the air conditioner’s piping may be

heard. Also, noise may be particularly noticeable for about 2 to

3 minutes after starting operation (sound of coolant ﬂ owing)

—



During Heating operation, a sizzling sound may be heard

occasionally. This sound is produced by the Automatic

Defrosting operation.

Smells:



Some smell may be emitted from the indoor unit. This smell is

the result of room smells (furniture, tobacco, etc.) which have

been taken into the air conditioner.

—

Mist or steam are

emitted:



During Cooling or Dry operation, a thin mist may be seen emit-

ted from the indoor unit. This results from the sudden Cooling

of room air by the air emitted from the air conditioner, resulting

in condensation and misting.

—



During Heating operation, the outdoor unit’s fan may stop, and

steam may be seen rising from the unit. This is due to the Auto-

matic Defrosting operation.

Airﬂ ow is weak or stops:



When Heating operation is started, fan speed is temporarily

very low, to allow internal parts to warm up.



During Heating operation, if the room temperature rises above

the thermostat setting, the outdoor unit will stop, and the indoor

unit will operate at very low fan speed. If you wish to warm the

room further, set the thermostat to a higher setting.

—



During Heating operation, the unit will temporarily stop opera-

tion (between 4 and 15 minutes) as the Automatic Defrosting

mode operates. During the Automatic Defrosting operation,

will be shown on the remote controller display.



The fan may operate at very low speed during Dry operation or

when the unit is monitoring the room’s temperature.

—



In case of Multi-type unit, if multiple units are operated in

different operation modes as shown below, the units operated

afterward will stop and

 This air conditioner operates on the heat-pump principle,

absorbing heat from outdoor air and transferring that

heat indoors. As a result, the operating performance is

reduced as outdoor air temperature drops. If you feel that

insufﬁ cient heating performance is being produced, we

recommend you use this air conditioner in conjunction

with another type of heating appliance.

 Heat-pump air conditioners heat your entire room by

recirculating air throughout the room, with the result

that some time may be required after ﬁ rst starting the air

conditioner until the room is heated.

*When Indoor and Outdoor Temperature

are High

 When both indoor and outdoor temperatures are high

during use of the heating mode, the outdoor unit’s fan

may stop at times.

*Microcomputer-controlled Automatic

Defrosting

 When using the Heating mode under conditions of low

outdoor temperature and high humidity, frost may form

on the outdoor unit, resulting in reduced operating per-

formance.

In order to prevent this kind of reduced performance,

this unit is equipped with a Microcomputer-controlled

Automatic Defrosting function. During the defrost cycle,

the indoor fan will shutdown and

will be displayed

on the remote controller. It will take anywhere from 4 to

15 minutes before the air conditioner starts up again.

 After heating operation stops, if frost forms on the outdoor

unit, the unit will start Automatic Defrosting operation.

At this time, the outdoor unit will automatically stop after

operating for a few minutes.

OPERATING TIPS

Mode operation: AUTO

About Mode Operation

During Heating mode:

Set the thermostat to a temperature set-

ting that is higher than the current room

temperature. The Heating mode will not

operate if the thermostat is set lower

than the actual room temperature.

During Cooling/Dry mode:

Set the thermostat to a temperature set-

ting that is lower than the current room

temperature. The Cooling and Dry modes

will not operate if the thermostat is set

higher than the actual room temperature

(in Cooling mode, the fan alone will ope-

rate).

During Fan mode:

You can not use the unit to heat and

cool your room.

* Heating:



Use to warm your room.



When Heating mode is selected, the air conditioner will operate at

very low fan speed for about 3 to 5 minutes, after which it will switch

to the selected fan setting. This period of time is provided to allow

the indoor unit to warm up before beginning full operation.



When the room temperature is very low, frost may form on the out-

side unit, and its performance may be reduced. In order to remove

such frost, the unit will automatically enter the defrost cycle from

time to time. During Automatic Defrosting operation, the heat opera-

tion will be interrupted.



After the start of heating operation, it takes sometime before the

room gets warmer.

Cooling:



Use to cool your room.

Dry:



Use for gently cooling while dehumidifying your room.



You cannot heat the room during Dry mode.



During Dry mode, the unit will operate at low speed; in order to

adjust room humidity, the indoor unit’s fan may stop from time to

time. Also, the fan may operate at very low speed when adjusting

room humidity.



The fan speed cannot be changed manually when Dry mode has

been selected.

Fan:



Use to circulate the air throughout your room.

COOLING MODEL



When the room temperature is 4 °F higher than the set

temperature, the mode will switch between Cooling and

Drying.



During the Drying mode operation, the FAN setting

should be switched to LOW for a gently cooling effect

during which the fan may temporarily stop rotating.



When the room temperature is near the thermostat set-

ting, the air conditioner will begin monitor operation.

In the monitor operation mode, the fan will operate at a

very low speed. If the room temperature subsequently

changes, the air conditioner will once again select the

appropriate operation (Heating or Cooling) to adjust the

temperature to the value set in the thermostat.

OPERATING TIPS

Multi-type Air conditioner

This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units to be

operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.

Simultaneous Use of Multiple Units

Instructions relating to inverter (



) are applicable only to “INVERTER MODEL”.

If the indoor unit is instructed to do an operating mode

that it cannot perform,

will be shown on the re-

mote controller display and the unit will go into the

standby mode.

Heating mode and cooling mode (or dry mode)

Heating mode and fan mode



 Operation can be done in the following different operat-

ing modes.

Cooling mode and dry mode

Cooling mode and fan mode

Dry mode and fan mode



 The operating mode (heating mode or cooling (dry)

mode) of the outdoor unit will be determined by the

operating mode of the indoor unit that was operated

ﬁ rst.If the indoor unit was started in fan mode, the op-

erating mode of the outdoor unit will not be determined.

For example, if indoor unit (A) was started in fan mode

and then indoor unit (B) was then operated in heating

mode, indoor unit (A) would temporarily start operation

in fan mode but when indoor unit (B) started operating

in heating mode,

will be shown on the unit (A)

remote controller display and it would go into standby

mode. Indoor unit (B) would continue to operate in heat-

ing mode.

 When using a multi-type air conditioner, the multiple

indoor units can be operated simultaneously, but when

2 or more indoor units of the same group are oper-ated

simultaneously, the heating and cooling efﬁ ciency will

be less than when a single indoor unit is used alone.

Accordingly, when you wish to use more than 1 indoor

unit for cooling at the same time, the use should be

concentrated at night and other times when less output

is required. In the same way, when multiple units are

used simultaneously for heating, it is recommended that

they be used in conjunction with other auxiliary space

heaters, as required.

 Seasonal and outdoor temperature conditions, the struc-

ture of the rooms and the number of persons present

may also result in differences of operating efﬁ ciency.We

recommend that you try various operating patterns in

order to conﬁ rm the level of heating and cooling output

provided by your units, and use the units in the way that

best matches your family's lifestyle.

 lf you discover that 1 or more units delivers a low level

of cooling or heating during simultaneous operation,

we recommend that you stop simultaneous operation

of the multiple units.



 Operation cannot be done in the following different

operating modes.

 Should the power supply to the air conditioner be inter-

rupted by a power failure, the air conditioner will restart

automatically in the previously selected mode once the

power is restored.

 Use of other electrical appliances (electric shaver, etc.) or

nearby use of a wireless radio transmitter may cause the

air conditioner to malfunction. In this event, temporarily

disconnect the power supply, reconnect it, and then use

the remote controller to resume operation.

AUTO Restart

In Event of Power Interruption

Notice

* During use of the heating mode, the top of the indoor

unit may become warm, but this is due to the fact that

coolant is circulated through the indoor unit even when

it is stopped; it is not a malfunction.

* During use of the heating mode, the outdoor unit will

occasionally commence the defrost operation for brief

periods. During the defrosting operation, if the user sets

the indoor unit for heating again, the defrosting mode

will continue, and the heating operation will begin after

completion of defrosting, with the result that some time

may be required before warm air is emitted.

SELF-DIAGNOSIS

When “Er” in Temperature Display is displayed, inspection of the air conditioning system is necessary. Please consult

authorized service personnel.
