CAUTION

| ●    A circuit breaker should be installed depending on the mounting site of the unit. Without a circuit breaker, the danger of electric shock exists.

●    Do not install near location where there is flammable gas. The outdoor unit may catch fire if flammable gas leaks around it.

●    Please ensure smooth flow of water when installing the drain hose.

●    Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist flows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may deform and in the worst case, break the plastic parts of the indoor unit.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

WARNING

• Should an abnormal situation arise (like burning smell), please stop operating the unit and turn off the circuit breaker. Contact your agent. Fault, short circuit or fi re may occur if you continue to operate the unit under abnormal situation.
• Please contact your agent for maintenance. Improper self-maintenance may cause electric shock and fire.
• Please contact your agent if you need to remove and reinstall the unit. An electric shock or fi re may occur if you remove and reinstall the unit yourself improperly.
• If the supply cord is damaged, it must be replaced by the special cord obtainable at authorized service/parts centers.
• If the air conditioner is not cool, one possible cause could be due to refrigerant leakage, so consult your dealer.

The refrigerant gas used in the air conditioner is harmless. But if refrigerant gas leaks into the room, harmful products are generated when in contact with fi re from appliances such as a stove heater. When there is refrigerant gas accumulation in the room, immediately stop the air conditioner. Open the windows for ventilation and contact your agent.

PRECAUTIONS DURING OPERATION

● Avoid an extended period of direct air flow for your health.

● Do not insert a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high speed, it will cause injury. Before cleaning, be sure to stop the operation and turn the breaker OFF.

● Do not use any conductor as fuse wire, this could cause fatal accident.

● During thunder storm, disconnect and turn off the circuit breaker.

●  Spray cans and other combustibles should not be located within a meter of the air outlets of both indoor and outdoor units. As a spray can’s internal pressure can be increased by hot air, a rupture may result.

PRECAUTIONS DURING OPERATION

• The product shall be operated under the manufacturer’s specification and not for any other intended use.
• Do not attempt to operate the unit with wet hands, this could cause fatal accident.
• When operating the unit with burning equipment, regularly ventilate the room to avoid oxygen insufficiency.
• Do not direct the cool air coming out from the air-conditioner panel to face the household heating apparatus as this may affect the working of apparatus such as the electric kettle, oven etc.
• Please ensure that the outdoor mounting frame is always stable, firm and without defect. If not, the outdoor unit may collapse and cause danger.
• Do not splash or direct water to the body of the unit when cleaning it as this may cause a short circuit.
• Do not use any aerosol or hair sprays near the indoor unit. This chemical can adhere on the heat exchanger fin and block the evaporation water fl ow to drain pan. The water will drop on the tangential fan and cause water to splash out from the indoor unit.
• Please switch off the unit and turn off the circuit breaker during cleaning, the high-speed fan inside the unit may cause danger.
• Turn off the circuit breaker if the unit is not to be operated for a long period
• Do not climb on the outdoor unit or put objects on it.
• Do not put a water container (like a vase) on the indoor unit to avoid water dripping into the unit. Dripping water will damage the insulator inside the unit and causes a short-circuit.
• Do not place plants directly under the air flow as it is bad for the plants.
• When operating the unit with the door and windows opened, (the room humidity is always above 80%) and with the air deflector facing down or moving automatically for a long period of time, water will condense on the air defl ector and drips down occasionally. This will wet your furniture. Therefore, do not operate under such conditions for a long time.
• If the amount of heat in the room is above the cooling or heating capability of the unit (for example: more people entering the room, using heating equipment and etc.), the preset room temperature cannot be achieved.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

MULTI-AIR CONDITIONER

Several indoor units can be connected to one outdoor unit. You can operate only one unit or several units according to your needs.

Combination of Operations

When operation mode is selected

You cannot operate the indoor units in the following combinations

Heating

| Cooling
Dehumidifying
Fan

• The indoor unit which is turned on fi rst continues to operate. Other indoor units which are turned on later go into stanby mode and the operation lamp lights.
• To operate the indoor units turned on later, set the operation mode as same as the indoor unit turned on first.

During automatic operation

When heating operation is automatically selected for the fi rst indoor unit, the next indoor unit will then start to heat. Also, if cooling or dehumidifying is automatically selected for the fi rst indoor unit, the next indoor unit will also start to cool or dehumidify

Adjusting the Number of Indoor Units:

Decrease the number of indoor units to be operated especially when it is very hot or cold or when you want to reach the present temperature quickly

Stopped Indoor Units:

When an indoor unit is operated in the cooling, heating or dehumidifying mode in the room, the sound of refrigerant flow may be heard from a stopped indoor unit or a stopped indoor unit may become warm. This is because the indoor unit returns refrigerant to the outdoor unit to be ready for operation.

WARNING

• Before cleaning, stop unit operation with the remote controller and turn off the circuit breaker

CAUTION

• Do not expose the unit to water as it may cause an electric shock.
• For cleaning inside the air conditioner, consult your sales agent.
• Avoid using detergent when cleaning the heat exchanger of the indoor unit. Unit failure may result.
• When cleaning the heat exchanger with a vacuum cleaner, make sure to wear gloves so as not to injure your hands on the heat exchanger fins.

PRE-FILTER

Clean the Pre-fi lter, as it removes dust inside the room. In case the Prefi lter is full of dust, the air fl ow will decrease and the cooling capacity will be reduced. Further, noise may occur. Be sure to clean the Pre-fi lter following the procedure below.

Procedure

1. Pull the filter toward the center until it detaches from the holders. Then take it out from holders (refer to diagram).
2. Remove dust from the fi lter using a vacuum cleaner. If there is too much dust, use neutral detergent. After using neutral detergent, wash with clean water and dry in the shade.
3. Install the filters. Gently insert back the filter into the holders

CAUTION

• Do not wash with hot water at more than 40°C. The filter may shrink.
• When washing it, shake off moisture completely and dry it in the shade; do not expose it directly to the sun. The filter may shrink.
• Do not operate the air conditioner with the filter removed. Dust may enter the air conditioner and cause trouble.

REGULAR INSPECTION

PLEASE CHECK THE FOLLOWING POINTS BY QUALIFIED SERVICE PERSONNEL EITHER EVERY HALF YEARLY OR YEARLY. CONTACT YOUR SALES AGENT OR SERVICE SHOP.

AFTER-SALE SERVICE AND WARRANTY

WHEN ASKING FOR SERVICE, CHECK THE FOLLOWING POINTS

Notes

• In quiet or stop operation, the following phenomena may occasionally occur, but they are not abnormal for the operation.
  1. Slight flowing noise of refrigerant in the refrigerating cycle.
  2. Slight rubbing noise from the fan casing which is cooled and then gradually warmed as operation stops.
• The odor will possibly be emitted from the room air conditioner because the various odor, emitted by smoke, foodstuffs, cosmetics and so on, sticks to it. So the air filter and the evaporator regularly must be cleaned to reduce the odor.
• Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above inspections. Inform your agent of the model of your unit, production number, date of installation. Please also inform him regarding the fault.
