NOTE

To protect your customer rights, it is very important that you follow cleaning and service instructions carefully. Failure to do so may result in your rights being forfeited.

THE REFRIGERANT

• To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The used refrigerant is the fluoride R32, which is specially cleaned. The refrigerant is flammable and inodorous.
  Furthermore, it can lead to explosion under certain conditions. But the flammability of the refrigerant is very low. It can be ignited only by fire.
• Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The influence upon the greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a really high energy efficiency. The units therefore need a less filling.

WARNING:

Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacture. Should repair be necessary, contact your nearest authorized Service Centre. Any repairs carried out by unqualified personnel may be dangerous. The appliance shall be stored in a room without continuously operating ignition sources. (for example: open flames, an operating gas appliance or an operating electric heater.) Do not pierce or burn.

Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer's instructions only. Be aware that refrigerants not contain odour.

1. Position the air filter and Titanium Apatite Photocatalytic Air-Purifying Filter as they were previously and close the front panel.

- Operation without air filters may result in problems as dust will accumulate inside the indoor unit.

1. Wash the air filters with water or clean them with a vacuum cleaner.

- If the dust is not removed easily, wash the filters with neutral detergent diluted with lukewarm water, then allow them to dry in the shade.

- It is recommended to clean the air filters every week.

Titanium Apatite Photocatalytic Air-Purifying Filter

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

Maintenance

1. Vacuum out dust and soak in warm water or water for about 10 to 15 minutes if the dirt is heavy.
2. Do not remove the filter from the frame when washing with water.
3. After washing, shake off remaining water and allow to dry in the shade.
4. As the material is made out of paper, do not wring 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:

• cannot deodorise the air.
- cannot clean the air.
• results in poor heating or cooling.
- may cause odour.

Before a long idle period

1. Operate in "FAN only" mode for several hours on a fine day to dry out the inside.
2. Press the "Mode" button and select "FAN" operation.
3. Press the "ON/OFF" button and start operation.
4. After operation stops, turn off the circuit breaker for the room air conditioner.
5. Remove, clean and reinsert the air filters.
6. Take out batteries from the remote control.

Before using after a long idle period

• Check that the base, stand and other fittings on the outdoor unit have not deteriorated or corroded.
• Check that nothing is blocking the air inlets and outlets of the indoor and outdoor units.
• Check that the drain water flows smoothly out of the drain hose during COOL or DRY operation. If no drain water is visible, water may be leaking from the indoor unit. Stop operation and contact the service agent if this is the case.

OPERATING GUIDE

Operating principle and special functions for cooling

Principle:

The air conditioner absorbs heat in the room and transmits/discharges this heat outdoors so that the indoor ambient temperature decreases. The unit's cooling capacity will increase or decrease depending on the outdoor ambient temperature.

Anti-freezing function:

If the unit is running in COOL mode and at a low temperature, frost will form on the heat exchanger. When the indoor heat exchanger temperature falls below 0 °C , the indoor unit microcomputer will stop the compressor from running and protect the unit.

Working principle and special functions for heating

Principle:

• The air conditioner absorbs heat from outdoors and transmits this indoors, thereby increasing room temperature. This is the heat pump heating principle. Heating capacity will fall depending on the decrease in the outdoor temperature.
• If the outdoor temperature becomes very low, please operate in conjunction with other heating equipment.

Defrosting:

• When the outdoor temperature is low but there is high humidity, after a long period of operation frost will form on the outdoor unit. This will impact the heating effect and at this point the auto-defrosting function will activate and the heating will cease to run for 8-10 minutes.
• During auto-defrosting, the fan motors of the indoor unit and outdoor unit will stop.
• During defrosting, the indoor indicator will flash and the outdoor unit may emit vapor. This is due to the defrosting and is not a malfunction.
  • After defrosting is finished, the heating will be restored automatically.

Anti-cold wind function:

In Heat mode, if the indoor heat exchanger has not achieved a certain temperature, the indoor fan motor will not start, thus preventing the blowing of cool wind (within 3 minutes):

1. The heat operation has just begun.
2. After the auto-defrosting operation is finished.
3. Heating at low temperatures.

The climate type of this unit is as noted on the nameplate.

• The temperature should not be set lower than what you need. Otherwise this will result in increased energy costs.
• To distribute cool air throughout the room, adjust the air flow direction as shown by the arrows (see picture) to diffuse the cool air.
• Clean the air filter every week for more efficient performance.
• Close windows and doors while operating the unit to prevent escape of cooled air and to save energy.
• Close curtains and/or glass windows when cooling to prevent heating of the room by sunlight, which may result in higher electricity costs.
• In the event of ineffective ventilation, occasionally open the window(s) to ventilate the room, though not so long that a significant amount of cooled air will escape.

OPERATING PRECAUTIONS

• Check the electrical system (voltage and frequency). Use the appropriate power supply, as indicated on the unit, to operate the air conditioner. Use only fuses with the specified capacity. Do not use loose wiring instead of fuses.
• Turn off the air conditioner if electricity interference occurs while running. If the unit is not to be used for a long period of time, turn off the main switch of the power supply.
• Do not insert objects into the air inlet or outlet when the air conditioner is running as this may cause damage or personal injury. Also pay special attention when children are present.
• Do not place any obstacle against the air flow direction of the indoor and outdoor unit. Inefficient performance or malfunction may result.
• Do not aim the air flow directly at people, especially infants, the elderly or medical patients.
• Do not place a heater or any other heat source close to the unit. The heat may degrade the plastic parts
