Indoor Unit
1. WIDE AIRFLOW
The new wide shape vane capable of wide angle air supply provides comfort even at the corners of a room regardless of cooling and heating operation. A reduction in the air speed by 20% compared to the conventional product eliminates uncomfortable draft sensation for friendly air conditioning.
2. WAVE AIRFLOW SYSTEM (HEATING MODE)
The wave airflow system has 4 vanes where each vane runs independently. Repeating of horizontal and down blows with a time lag allows the conditioned warm air to be distributed even to room corners thus preventing uneven room temperature distribution.
Operation image of "Wave Airflow"
3. AUTOMATIC AIR SPEED ADJUSTMENT MODE
The automatic air speed adjustment mode is provided in addition to the 4 air speed stages of "High/Medium 1/Medium 2/ Low." Air speed can be changed freely in accordance with a difference between the set temperature and the room temperature. The automatic air speed adjustment mode presents quick cooling of a room with the high mode, such as at the starting up of cooling operation, for example. After the room temperature is stabilized, the low mode will be applied by automatic switching to keep your comfort.

4. i-see Sensor (OPTIONAL CORNER PANEL)
The i see sensor is a radiation temperature sensor originated from Mitsubishi’s new technology. In order to create a really comfortable space in shops and offices, it is essential to control the temperature near the floor where occupants/visitors gather. The i see sensor measures the infrared rays generated from the surrounding wall and floor surface at an angle of 360° and the infrared ray energy is computed to convert it into the value of temperature. In addition, the floor temperature at distant spots (radiation temperature) is also measured to supply the optimum airflow to realize comfort which was never experienced in the past.

5 4-WAY AIR FLOW SYSTEM
5-1. PLACEMENT OF THE AIR OUTLETS
•For this grille, the blowout direction comes in 11 patterns.
Also, by setting the remote controller to the appropriate settings, you can adjust the air flow and speed. Select the settings from Table1 according to the location in which you want to install the unit.
1) Decide on the pattern of the airflow direction.

5-2. BRANCH DUCT HOLE AND FRESH AIR INTAKE HOLE
At the time of installation, use the duct holes (cut out) located at the positions shown in following diagram, as and when required.
• A fresh air intake hole for the optional multi function casement can also be made.
Note:
The figures marked with * in the drawing below represent the dimensions of the main unit excluding those of the optional multi function casement.
When installing the optional multi function casement, add 5-5/16” (135 mm) to the dimensions marked on the figure. When installing the branch ducts, be sure to insulate adequately.
Otherwise, condensation and dripping may occur.

5-3. OPERATION IN CONJUNCTION WITH DUCT FAN (Booster fan)
•Whenever the indoor unit is operating, the duct fan also operates.
(1)Connect the optional multiple remote controller adapter (PAC-SA88HA-E) to the connector CN51 on the indoor controller board.
(2)Drive the relay after connecting the 12V DC relay
between the Yellow and Orange connector lines. MB: Electromagnetic switch power relay for duct fan.
X: Auxiliary relay (For DC 12V, coil rating: 1.0W or smaller)
