• Test operation can be carried out using the remote control unit or at the outdoor unit. (If carrying out test operation at the outdoor
unit, refer to "TEST OPERATION" in the outdoor unit installation manual.)
• If using the remote control unit to carry out test operation, follow the procedure given below.
NOTE 1
These units are equipped with connection error prevention circuits. If the units do not operate, it is possible that the connection
error prevention circuits have operated. In such cases, check that the power wires (connected to terminals
control wires
