function.

(1) Automatic running (applicable to fan-coil model)

When the running mode is turned to automation after starting the system, the system

will first determine the running mode according to the current room temperature and then

will run according to the determined mode. Tr in the following selection conditions

means room temperature, Ts means setting temperature, Tp means temperature of indoor

coil pipe

a. Tr≥23℃ running refrigerating mode Ts=26℃

b. Tr<23℃ running fan only mode

(2) Indoor temperature control

(3) Dehumidification running

The compressor, outdoor fan and indoor fan will run as per the following working

pattern so as to realize the refrigerating running of dehumidification:

① Tr> Ts+2℃, compressor, outdoor fan run continuously, indoor fan runs as per

setting wind speed (State 1);

② Ts+2℃≥Tr≥Ts, compressor, outdoor fan run intermittently with 10 minutes

ON, 6 minutes OFF. (Compressor and outdoor fan are synchronous) indoor fan

runs in fixed lower wind speed, and will cease at the stand-by time of 3 minutes

(State 2)

Is the air filter dirty? Normally it should becleaned every 15 days.Are there any obstacles before inlet and outlet?Is temperature set correctly?Are there some doors or windows left open?Is there any direct sunlight through thewindow during the cooling operation?(Usecurtain)Are there too much heat sources or too manypeople in the room during cooling operation?

Cause or check pointsPhenomenon

The system does not restartimmediately.

Noise is heard:

Smells are generated.

Mist or steam are blown out.

Does not work at all.Multiplecheck

NormalPerformanceinspection

Poor cooling

Before asking for service, check the following first.

When unit is stopped, it won't restartimmediately until 3 minutes have elapsedto protect the system.When the electric plug is pulled out andreinserted, the protection circuit will workfor 3 minutes to protect the air conditioner.

During unit operation or at stop, a swishingor gurgling noise may be heard. At first 2-3minutes after unit start, this noise is morenoticeable. (This noise is generated byrefrigerant flowing in the system.)During unit operation, a cracking noise maybe heard. This noise is generated by thecasing expanding or shrinking because oftemperature changes.Should there be a big noise from air flow inunit operation, air filter may be too dirty.

This is because the system circulates smellsfrom the interior air such as the smell offurniture, cigarettes.

During COOL or DRY operation, indoor unitmay blow out mist. This is due to the suddencooling of indoor air.

Is power plug inserted?Is there a power failure?Is fuse blown out?
