refrigerant cycle DSW switches (DSW1 and RSW1 on outdoor
units, DSW5 and RSW2 on indoor units) and of the unit number
of the indoor units is suitable for the system. Check whether
indoor and outdoor units is correct. Pay particular attention to
the outdoor unit nunber, the refrigerant cycle number and the

measuring the resistance between the ground and the terminal
of the electrical components. If not, do not use the system until

Check that all cables, L1, L2, L3 and N (R, S, T and N) are
correctly connected to the power line. If they are not correctly
connected, the unit will not work and the remote control will
