Annual energy efficiency perfomance ratio is calculated by overall capacity and average operaing time (apr 500 hours) multiplication in full-load coling mode operation.

Cooling capacity

is device cooling capaciy (demanded in kWh) in full-load cooling mode operation. ERR energy

label index is ratio of cooling capacity to its electric energy input attainment. Energy label depends on ERR index rate.

3.3 Titanium Apatite Photocatalytic

Air-Purifying Filter

The Titanium Apatite Photocatalytic Air-Purifying Filter can be renewed by washing it with water once every 6 months. We recommend replacing it once every 3 years.

● Maintenance

1. Vacuum dusts, and soak in warm water or water for about 10 to 15 minutes if dirt is heavy.

2. Do not remove filter from frame when washing with water.

3. After washing, shake off remaining water and dry in the shade.

4. Since the material is made out of paper, do not wring out the filter when removing water from it.

● Replacement

Remove the tabs on the filter frame and replace with a new filter.

• Dispose of the old filter as flammable waste.

NOTE

• Operation with dirty filters: (1) cannot deodorize the air. (2) cannot clean the air. (3) results in poor heating or cooling. (4) may cause odour.

Check

Check that the base, stand and other fittings of the outdoor unit are not decayed or corroded. Check that nothing blocks the air inlets and the outlets of the indoor unit and the outdoor unit.

Check that the drain comes smoothly out of the drain hose during COOL or DRY operation.

• If no drain water is seen, water may be leaking from the indoor unit. Stop operation and consult

the service shop if this is the case.

3.4 Before a long idle period

1. Operate the “FAN only” for several hours on a fine day to dry out the inside.

• Press “MODE” button and select “FAN” operation.

• Press “ON/OFF” button and start operation.

Working principle and special functions for cooling

Principle:

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.

Anti-freezing function:

If the unit is running in COOL mode and in low temperature, 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.

Working principle and special functions for heating

Principle:

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.

OPERATION INSTRUCTIONS

℃

Defrosting:

When outdoor temperature is low but high humidity, after a long while running, 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(or display “H1”), the outdoor unit may emit vapor,

After defrosting finished,the heating will recover automatically.

Anti-cool wind function:

In Heat mode, the following three kinds of status, if indoor heat exchanger hasn't achieve certain temperature that indoor fan motor will not start, in this way to prevent blowing cool

wind (within 3mins):

1. Heat operation just startedup. 2. After Auto defrosting operation is finished.

3. Heating under low temperature.

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

This is due to the defrosting, it isn't malfunction.

3) Once refrigerant piping and drain piping connections are complete, fill in the gap of the through hole with putty. A gap can lead to condensation on the refrigerant pipe, and drain pipe, and the entry of insects into the pipes.

4) Attach the front panel and front grille in their original positions once all connections are complete.

Flaring the pipe end

1)Cut the pipe end with a pipe cutter.

2)Remove burrs with the cut surface facing downward so that the chips do not enter the pipe.

3)Fit the flare nut on the pipe.

4)Flare the pipe.

5)Check that the flaring is properly made.

WARNING

1) DO not use mineral oil on flared part.

2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.

3) Never use piping which had been used for previous installations. Only use parts which are delivered with the unit.

4) Do never install a drier to this R410A unit in order to guarantee its lifetime.

5) The drying material may dissolve and damage the system.

6) Incomplete flaring may cause refrigerant gas leakage.

The pipe end must be evenly flared in a perfect circle

Caution on piping handling

1)Protect the open end of the pipe against dust and moisture.

2)All pipe bends should be as gentle as possible. Use a pipe bender for bending. (Bending radius should be 30 to 40mm or larger.)

If no flare cap is available,cover the flare mouth with tape to keep dirt or water out.

Selection of copper and heat insulation materials

When using commercial copper pipes and fittings, observe the

Gas pipe

Inter-unit wiring

following:

1)Insulation material: Polyethylene foam Heat transfer rate:0.041 to 0.052W/mK(0.035 to 0.045kca/(mh Refrigerant gas pipe’s surface temperature reaches 110 max.

Choose heat insulation materials that will withstand this temperature.

INSTALLATION NSTRUCTIONS

Checking for gas leakage

1)Check for leakage of gas after air purging

2)See the sections on air purges and gas leak checks in the installation manual for the outdoor unit.

Check for leakage here Apply soapy water and check carefully for leaking gas. wipe soapy water off after the check is complete.

Attaching the connection pipe

Attach the pipe after checking for gas leakage, described above.

1)Cut the insulated portion of the on-site piping, matching it up with the connecting portion.

2)Secure the slit on the refrigerant piping side with the butt joint on the auxiliary piping using the tape, making sure there are no gaps.

3)Wrap the slit and butt joint with the included insulation sheet, making sure there are no gaps.

CAUTION

1)Insulate the joint of the pipes securely. Incomplete insulation may lead to water leakage.

2)Push the pipe inside so it does not place undue force on the front grille.

Connecting the drain hose

Insert the supplied C drain hose into the socket of the drain pan. Fully insert the drain hose until it adheres to a seat of the socket.

Wiring

With a Multi indoor unit, install as described in the installation manual supplied with the Multi outdoor unit.

Live the sensor securing plate, remove the front metal plate cover, and connect the branch wiring to the terminal block.

1)Strip wire ends (15mm)

2)Mach wire colours with terminal numbers on indoor and outdoor unit’s terminal blocks and firmly screw wires to

the corresponding terminals.

3)Connect the earth wires to the corresponding terminals.

4)Pull wires to make sure that they are securely latches up, then retain wires with wire retainer.

CAUTION

1)Do not use tapped wires, stranded wires, extensioncords, or starburst connections, as they may cause overheating,

electrical shock, or fire.

2)Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc, from
