1.
Turn the power off and take off the cover of the outdoor units.
2. Fix the case with bolts to the side of the control box referring to
the figure on the right side.
In case of FJM outdoor unit, there is not enough space to fix all
parts of transmitter. So you may use transmitter main PCB.
3. Attach the transmitter main PCB to the case, then connect F1/
F2 lines, R1/R2 lines which are upper controller communication
cables and DC 12V power cables to the interface module referring
to the figure on page 17. (Upper controller power should be off.)
4. You must check the position of dip switch on the transmitter's
main PCB and the main PCB of MH**/NJ** indoor units. For AQV**/
AJN**/AR** indoor units, refer to page 30.
5. Assemble a cover of the outdoor unit and turn the power on.
6. Check the communication status.
7. If you install a transmitter to the outdoor unit, every indoor unit
which is connected to the outdoor unit can be controlled simulta-
neously.
8. Each outdoor unit connected to the same centralized controller
has its own transmitter.
