GENERAL INFORMATION

• Inverter
  On start-up, the air conditioner will operate at maximum capacity to bring the room quickly down to desired temperature. Once the temperature in the room begins to achieve the set temperature, the air conditioner will reduce its capacity and energy usage to the minimum capacity and input ratings.

• 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 insuffi cient, 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 fi rst 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 briefl y (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.

• 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.

• Indoor unit temperature and humidity range
  Permissible ranges of temperature and humidity are as follows:Indoor temperature| Cooling/Dry| [°C]| 18 to 32
  ---|---|---|---
  | Heating| [°C]| 16 to 30
  Indoor humidity| [%]| 80 or less *”

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 emperature 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 informations

• Do not use the air conditioner for any purpose other than room cooling/dry, room heating or fan.

• For the permissible ranges of temperature and humidity for the outdoor unit, refer to the outdoor unit installation manual.

• 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.

10.4. Multi-type air conditioner
This indoor unit can be connected to a multi-type outdoor unit. The multi-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-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 effi ciency 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 diff erences of operating effi ciency. We recommend that you try various operating patterns in order to confi rm 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 diff erent operating modes. If the indoor unit is instructed to do an operating mode that it cannot perform, [ ] indicator on the indoor unit will fl ash (1 second on, 1 second off ) and the unit will go into the standby  ode.  Heating mode and Cooling mode (or Dry mode) Heating mode and Fan mode
• Operation can be done in the following diff erent 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  theoperating mode of the  indoorunit that was operated fi  rst.If the indoor unit was started in the Fan mode,  the operating mode of the outdoor unit  ill 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, [ ] indicator for indoor unit (A) would begin to fl ash (1 second on, 1 second off ) and it would go into standby mode. Indoor unit (B) would continue to operate in Heating mode.

10.5. Simultaneous multi air conditioner
This indoor unit can also be connected to a simultaneous multi connection that enables simultaneous operation of multiple indoor units by connecting the outdoor unit using a separation tube.
NOTES: The number of connectable indoor units and connectable  type of the separation tube vary by model.
