9. GENERAL INFORMATION

• Inverter
At the start of operation, large amount of power is used to bring the room
quickly to the desired temperature. Afterwards, the unit automatically
switches to a low power setting for economic and comfortable operation.

• Heating performance
This air conditioner operates on the heat-pump principle, absorbing heat from air outdoors and transferring that heat to the indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops.

If you feel that the heating performance is insufficient, we recommend you to use this air conditioner in conjunction with other kinds of heating appliance.

please consult with your installation technician to ensure the unit is correctly sized for the room space required.
Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

• Automatic defrosting operation
When outdoor temperature is very low with high humidity, frost may form on the outdoor unit during the Heating operation, and it could reduce the operating performance of the product.

For frost protection, a microcomputer-controlled automatic defrost function is equipped in this air conditioner.

If frost forms, the air conditioner will temporarily stop, and defrost circuit will operate briefly (maximum of 15 minutes.)

If frost forms on the outdoor unit after the Heating operation, the outdoor unit will stop automatically after it operates for a few minutes. Then the automatic defrosting operation starts.

If you set to the Heating operation during the Automatic defrosting operation, the Automatic defrosting operation will continue. The Heating operation will begin after completion of defrosting. As a result, it may take some time before warm air is emitted.

• Hot start
The indoor unit prevents cold drafts when the Heating operation begins.
The indoor unit fan will not operate or it will operate at a very low speed until the heat exchanger reaches the set temperature.

• Auto-restart function
In Event of Power Interruption
Should the power supply to the air conditioner be interrupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.

• Malfunctions caused by other electrical devices
Use of other electrical appliances such as an electric shaver or nearby use of a wireless radio transmitter may cause the malfunction of the air conditioner.

If you encounter such a malfunction, disconnect the power supply once.
Then reconnect it, and resume operation by using the remote controller.

• Operable conditions of temperature and humidity
Permissible ranges of temperature and humidity are as follows:

•1: If the air conditioner is used continuously for many hours, water may condense on the surface and drip.
• If the unit is operated under the conditions except the permissible temperature range, the air conditioner operation may stop because of the automatic protection circuit working.
• Depending on the operating conditions, the heat exchanger may freeze, causing water leakage or other malfunction. (in the Cooling or Dry mode).

• When indoor and outdoor temperatures are high
When both indoor and outdoor temperatures are high during use of the
Heating mode, the outdoor unit’s fan may stop at times.

• Low ambient cooling
When the outdoor temperature drops, the outdoor unit’s fans may switch to low speed, or one of the fans may stop intermittently.

• Other information
• Do not use the air conditioner for any purpose other than room cooling/dry, room heating or fan.
• During the Heating mode, the top of the indoor unit may become warm, but this is due to the fact that coolant is circulated through the indoor unit even when it is stopped; it is not a malfunction.

10. OPTIONAL PARTS

10.1. Remote control
The remote controller is optional. You can select from th following types of remote control.
– Wireless remote controller
– Wired remote controller
To check the available model of remote controller, please consult authorized service personnel.
NOTE: Depending on the remote control, some function may be restricted. Please refer to the operation manual of the remote controller for details.
You can use both wireless and wired remote controller together.
However, some functions of the wireless remote controller may be restricted.

10.2. Multiple remote controller
You can connect two wired remote controllers to one air conditioner.
Either remote controller can control the air conditioner.
However, the timer functions cannot be used by the secondary unit.

10.3. Group control
One wired remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same settings.

10.4. Multi-split type Air Conditioner
NOTE: Depending on model, this function cannot be used. For details, consult authorized service personnel.
This indoor unit can be connected to a multi-split type outdoor unit. The multi-split type air conditioner allows multiple indoor units to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.

Simultaneous Use of Multiple Units

• When using a multi-split type air conditioner, the multiple indoor units can be operated simultaneously, but when 2 or more indoor units of the same group are operated simultaneously, the heating and cooling efficiency will be less than when a single indoor unit is used alone. Accordingly, when you wish to use more than 1 indoor unit for cooling at the same time, the use should be concentrated at night and other times when less output is required. In the same way, when multiple units are used simultaneously for heating, it is recommended that they be used in conjunction with other auxiliary space heaters, as required.

• Seasonal and outdoor temperature conditions, the structure of the rooms and the number of persons present may also result in differences of operating efficiency. We recommend that you try various operating patterns in order to confirm the level of heating and cooling output provided by your units, and use the units in the way that best matches your family’s lifestyle.

• If you discover that 1 or more units delivers a low level of cooling or heating during simultaneous operation, we recommend that you stop simultaneous operation of the multiple units.

• Operation cannot be done in the following different operating modes.
  Heating mode and Cooling mode (or Dry mode)
  Heating mode and Fan mode

• Operation can be done in the following different operating modes.
  Cooling mode and Dry mode
  Cooling mode and Fan mode
  Dry mode and Fan mode

• The operating mode (Heating mode or Cooling (Dry) mode) of the outdoor unit will be determined by the operating mode of the indoor unit that was operated first. If the indoor unit was started in the Fan mode, the operating mode of the outdoor unit will not be determined.

For example, if indoor unit (A) was started in the Fan mode and then indoor unit (B) was then operated in the Heating mode, indoor unit (A) would temporarily start operation in the Fan mode but when indoor unit (B) started operating in the Heating mode, indoor unit (A) would go into standby mode. Indoor unit (B) would continue to operate in the Heating mode.
