4 Connect the (white, 5p) louver motor con-
nector.
5 Place each of the connectors inside the con-
trol box.
Note (1) : If the air supply louver does not operate us-
ing the remote controller, check the
connector's connection, then turn the main
power supply OFF for 10 seconds or longer
and turn the power ON again.
7) If the vertical air-flow direction is fixed
• This decorator panel is designed so that you can fix the vertical air-flow direction at each air supply to match the
environment at your installation location. Set it as required by the customer. Furthermore, when the vertical air-flow
direction is fixed, remote control operation and all automatic controls are disabled. The actual setting may also differ
from the LCD display in the remote controller.
1 Turn off the main power supply (turn it off at the ground fault circuit breaker).
2 Disconnect the connector to the louver motor at the air supply you want to fix the position of.
Wrap vinyl electrical tape around the disconnected connector to insulate it.
3 Slowly move the vertical air-flow louver you want to fix the position of by hand and set the vertical air-flow
direction so that it is within the range shown in the table below.

* It can be set anywhere desires as long as it is within a range of 22.5 and 36.5 mm.
Note (1) : Do not set the position outside this range.
Doing so causes condensate to drip and to form as well as dirtying of the ceiling surface, and could cause abnormal operation.
