water maybe dripped from the air outlet in

cooling or drying mode.

3-minute Protection Function

If restart the unit immediately after stopping,

the compressor will start only 3 minutes later

to protect the machine.

Variation of Fan Speed

If fan speed in auto mode, it will automatically

lower when the room temperature close to the

setting temperature in cooling mode.

In heating mode,the compressor stops when the

room temperature at setting temperature and fan

turns into low speed or stops.

In Dry mode,fan speed will be automatically varied.

Remote Control:

There is a telecommunication interface for remote control on the control

panel of the indoor unit. After the peripheral equipment have been installed

in accordance with the instruction manual of the selected remote control

detector, the air conditioner will be computerized and controlled from a far-

away place.

refer to Centralized Controller installation and operation manual.

Main points of Operation

Prevent Cool Air Blowing Off

In heating mode,the indoor fan will not run

immediately after the unit starts to prevent

the cool air blowing off.

Defrosting Function

In heating mode, when frost formed on the outdoor heat

exchanger, the air conditioner will automatically defrost a

few minutes. During defrosting, both indoor and outdoor

fan will stop running. When defrosting finished, air condi-

tioner will automatically back to running.

Hints

The air conditioner absorbs heat form outside and

releases inside when in heating mode, therefore the

outside environmental temperature will affect heating

effects.

Power Failure Compensation(to be applied for a necessary situation):

After the power failure compensation is set, if power failure suddenly occurs while the air

conditioner is working,it will resume the previous working state when the power is supplied

again.

Setting Method: When the remote controller is on (excluding timer mode and fan mode),press

the ìsleepingî button on the remote controller 10 times within 5 seconds,and

after the buzzer rings 4 times,the air conditioner will enter the state of power

failure compenstation.

Cancel Method:Press the ìsleepingî button on the remote controller 10 times within 5 seconds,

and after the buzzer rings 2 timer,the power failure compensation mode will be

cancelled.

Note: When a power failure suddenly occurs during the air conditioner si working after the

power after the power failure compensationis set,if the air conditioner will not be used

for a long time, please cut off the power supply to prevent its operation from being res-

umed after the power is supplied again, or press the ì Switch On/Off î button after the

power comes again.

power is consumed even the air conditioner is in stop.

Clean the air filter, indoor unit and outdoor unit,and cover

the unit with dustcoat.

Pre-season Care

See that there is no bostacles blocking the air

inlet and air outlet of both indoor and outdoor

unit to avoid reduce the working efficiency.

Be sure to install the air filter, ensure that the air filter is not dirty. Otherwise may result in

machine damages or cause malfunciton due th dust inside the unit

To prevent compressor when start in HEAT mode,

please cut in the power supply switch 12 hours

before starting run,furthermore, always keep the

power supply switch on during the using senson.

Post-season Care

Troubleshooting

The followings are not malfuncition

Hua

Water flowing sound is heard

When the air conditoner is started, when the

compressor starts or stops during operation

or when the air conditioner is stopped,it som-

etimes sounds ì Bi- Bi-î or ìGodo-Godoî. It is

the flowing sound of the refrigerant , not a

malfunction.

Cracking sound is heard

It smells.

This is caused by heat expansion or contra-

ction of plastics

Air blown out from the indoor unit sometimes

smells. The smell results from smells of

furniture, paint , tobacco absorbed by indoor

unit.

During operation, white fog comes out of

indoor unit.

When in COOL or DRY mode, a thin water

fog can be seen blown out of unit ,this is the

condensed fog because the suddenly cooled

indoor air is blown out.

Automatically switch into FAN mode during

cooling.

To prevent frost from being accumulated on the

indoor unit heat exchanger, it sometimes auto-

matically switched into the FAN mode,but it will

soon back to the cooling mode.

The air conditioner cannot be restarted soon

after it stops.

Air conditioner does not start?

This is because of the self-protection function

of the system, therefore,it cannot be restarted

for about three minutes after it stops.

Air does not blow or the fan speed cannot be

changed during drying.

In DRY mode, when room temperature

becomes 2 C higher than temperature setting,

unit rill run intermittently at LO speed regardless

of FAN setting

Please wait for

three minutes

Troubleshooting

**?

OFF

During heating,indoor fan is still running even

unit is stopped.

To get ride of the excess heat, indoor fan will

continue running for a while after unit autom-

atically stops.

Water or vapor generated from the outdoor

unit during heating.

This happens when the frost accumulated on

the outdoor unit is removed (during defrosting

operation).

Defrosting operation

Please check the following things about your air conditioner before making a

service call.

Unit fails to start.

Is the power supply switch on ?

Power supply switch is not in

ON position.

Is city supply power normal ?

Is the earth leakage breaker

in action ?

Be sure to turn off the power

supply switch immediately and
