7-13. Installing the Receiver

The receiver can only be installed on the corner indicated in Fig. 1-219. Consider how the panel will
face when it is installed on the indoor unit.
1  Remove the air inlet grill.
2  Remove the screw holding the adjustable corner cover. Then slide the cover to the side and remove it. (Fig. 1-220)

3  To pass the wire through the panel, bend the part (shaded area) on the square hole and then
    pass wire protrudingfrom the wireless receiver through the grill. (Fig. 1-221)
4  After wiring according to the directions in “Wiringfor the Receiver”, leave enough wire length so that the
    receiver’s adjustable corner cover can be removed andfasten the wire with the clamper. (Fig. 1-221)
5  Hang the corner cover string on the pin of the ceiling panel (Fig. 1-222). Then slide the corner cover
    onto the ceiling panel until the three clips are correctly located, and then fix it in place with the screws.

Wiring Diagram

How to Connect the Wires

  Connect the wires from the receiver to the terminals for RC wiring on the indoor unit. (No polarity)

7-15. Test Operation

Attention

Preparation : 

Turn on the circuit breaker of units and then 

                       turn the power on. After the power is turned
                       on, remote controller operation is ignored for
                       approx. 1 minute because setting is being
                       made. This is not malfunction. (Contents 
                       received while setting are disabled.)
1. To start test operation, press and hold the emergency 
    operation button for 10 seconds.

 

2. The indication lamps (OPERATION, TIMER, STANDBY)
    blink during test operation.
3. To finish test operation, press and hold the emergency
    operation button for 10 seconds.

Temperature cannot be changed.
The test operation mode is automatically turned off in
60 minutes. (To prevent continuous test operation)
Outdoor units do not operate for approx. 3 minutes after 
the power is turned on or operation is stopped.

Before installing the receiver, see the sections on

“Wiringfor the Receiver” and “Setting Address Switches”.

Then check the settings of the [S003] DIP switch on the
