NAMES AND FUNCTIONS OF EACH PART

INDOOR UNIT

MODEL NAME AND DIMENSIONS

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 first continues to operate. Other indoor units which are turned on later go into standby 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 first 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 fl ow 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.

FOR USER’S INFORMATION

The Air Conditioner And The Heat Source In The Room

• Caution
  If the amount of heat in the room is above the cooling capability of the air conditioner (for example: more people entering the room, using heating equipments and etc.), the preset room temperature cannot be achieved.

• Not Operating For A Long Time

  • When the indoor unit is not to be used for a long period of time, please switch off the power from the mains. If the power from mains remains “ON”, the indoor unit still consumes about 3W in the operation control circuit even if it is in “OFF” mode.

• When Lightning Occurs

  • Warning
  • To protect the whole unit during lightning, please stop operating the unit and remove the plug from the socket.

• Interference From Electrical Products

• Caution

  • To avoid noise interference, please place the indoor unit and its remote controller at least 1m away from electrical products.

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-filter, as it removes dust inside the room. In case the Pre-filter 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-filter following the procedure below.

PROCEDURE

1. Pull the filter toward the center until it detached from the holders. Then take it out from holders (refer to diagram).
2. Remove dust from the filter using a vacuum cleaner. If there is too much dust, wipe the filter with wet cloth or sponge. Allow filter to dry in 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 fi lter 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.
