Anti-freezing function:

Working principle and special functions for heating

Principle:

Defrosting:

Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that indoor ambient temperature decreased, its cooling capacity will increase or decrease by

outdoor ambient temperature.

If the unit is running in COOL mode and in low te

mperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0 , the indoor unit microcomputer will stop compressor running and protect the unit.

℃

Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase room temperature. This is the heat pump heating principle, its heating capacity will be

reduced due to outdoor temperature decrease. If outdoor temperature becomes very low, please operate with other heating equipments.

When out frost will form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting

function will act, the heat running will stop for 8-10mins.

During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.

During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor. This is due to the defrosting, it isn't malfunction.

After defrosting finished,the heating will recover automatically.

door temperature is low but high humidity, after a long while running,

The climate type of this unit is according to the nameplate.

The external static pressures at which the appliance was tested should be zero Pa.

Notices for use

Anti-cool wind function:

In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't arrive at certain temp., indoor fan will not act, in order to prevent cool wind blowing(within 2 mins):

1. Heating starts. 2.After Auto Defrost finished. 3.Heating under the low temperature.

The operating temperature range (outdoor temperature) for cooling unit is -7℃~ 43℃； for cooling and heating unit is -7 ℃~43℃.

Troubleshooting

CAUTION

Don't attempt to repair the air conditioner by yourself, it can cause an electric shock or fire. Please check the following items before asking for repair, it can save your time and money.

Phenomenon

Troubleshooting

Not operate immediately when the air conditioner is restarted.

There's unusual smell blowing from the outlet after operation is started.

The unit has no peculiar smell by itself. If has, that is due to the smell accumulated in the ambient.

Solution method: Cleaning the filter. If problem still has, so need to clean air conditioner. (Please contact with the authorized maintenance center.)

Sound of water flow can be heard during the operation.

The air conditioner is started, when it is running the compressor started or stopped running, or the unit is stopped, sometimes there is swoosh or gurgle, the sound is due to refrigerant flowing they are not malfunctions.

In COOL mode, sometimes the mist emitted from the air outlet vent.

When the indoor temperature and humidity are very high, this phenomenon would happen. This is caused by the room air is swiftly cooled down. After running for a while, indoor temperature and humidity will fall down, the mist will die away.

Creaking noise can be heard when start or stop the unit.

This is caused by the deformation of plastic due to the changes of temperature.

The air humidity is on the high side.

Condensing water over flowed.

The connection position of indoor unit drainage pipe is loosed.

If water leakage in outdoor unit.

When the unit is running in COOL mode, the pipe and connection of pipe would be condensed due to the water cooled down.

When the unit is running in Auto Defrosting mode the ice thawed and flowed out.

When the unit is running in HEAT mode, the water adhered on heat exchanger dripped off.

Noise from indoor unit emitted. The sound of fan or compressor relay is switching

Installation of Drain Hose

Connect the drain hose to the outlet pipe of the indoor unit.

Bind the joint with rubber belt.

Put the drain hose into insulating tube.

Wrap the insulating tube with wide rubber belt to prevent the shift of insulating tube. Slant the drain hose downward

slightly for smooth drainage of condensing water.

Note: The insulating tube should be connected reliably with the sleeve outside the outlet pipe. The drain hose should be

slanted downward slightly, without distortion, bulge or fluctuation. Do not put the outlet in the water.

● Make sure that all wiring connections are secure and the cover plates are reinstalled

NOTE:

All wires between indoor and outdoor units must be connected by the qualified electric

contractor.

Electric wires must be connected correctly. Improper connection may cause malfunction.

Tighten the terminal screws tightly.

Make sure that the electric connections are earthed properly to prevent electric shock.

Installation of Indoor Unit

The piping can be output from right, right rear, left or left rear.

When routing the piping and wiring from the left or right side of indoor unit, cut off the tailings from the chassis when necessary(As shown in Fig.7)

Cut off the tailings 1 when routing the wiring only;

Cut off the tailings 1 and tailings 2 when routing both the wiring and piping.

Take out the piping from body case, wrap the piping,

power cords, drain hose with the tape and then make them pass through the piping hole. (As shown in Fig.8)

Hang the mounting slots of the indoor unit on the

upper hooks of the mounting plate and check if it is

firm enough.(As shown in Fig.9)

The installation site should be 250cm or more above

the floor.

Installation of Connection Pipe

Align the center of the piping flare with the related valve.

Screw in the flare nut by hand and then tighten the

nut with spanner and torque wrench by referring to the following:

NOTE: Connect the connection pipe to indoor unit at first and then to outdoor unit. Handle pi-

ping bending with care. Do not damage the connection

pipe. Ensure that the joint nut

is tightened firmly, otherwise, it may cause leakage.

Items to be checked Possible malfunction

Has it been fixed firmly?

The unit may drop, shake or emit noise.

Have you done the refrigerant leakage test?

It may cause insufficient cooling(heating) capacity

Is heat insulation sufficient?

It may cause condensation and dripping.

Is water drainage well?

It may cause condensation and dripping.

Is the voltage in accordance with the rated voltage marked on the nameplate?

It may cause electric malfunction or damage the part.

Is the electric wiring and piping connection installed correctly and securely?

It may cause electric malfunction

or damage the part. Has the unit been connected to a secure earth connection?

It may cause electrical leakage.

Is the power cord specified?

It may cause electric malfunction

or damage the part.
