WARNING:

Wrong wiring may cause a burn-out to some electrical parts.

Be sure to use the cord clamps attached to the product.

Do not damage or scratch the conductive core and inner insulator of power and inter-connecting cables when peeling them.

Be sure to comply with local regulations of the cable from outdoor unit to indoor unit.

(wire size and cabling method etc.)

Use the power and Inter-connecting cables with specified thickness, specified type and protective devices required.

The indoor - outdoor unit interconnecting wires must be A07 RN-F type (245 IEC 57) or higher, with synthetic rubber insulation with Neoprene coating, according to EN 60335-2-40 codes.

The mains supply connecting cable for 38VYX units, must be H07 RN-F type (245 IEC 57) or higher, with synthetic rubber insulation with Neoprene coating, according to EN 60335-2-40 codes.

Refer to the indoor unit installation manual for sizing of the power supply wires.

2.For inter connecting cable, do not use a wire jointed to another on the way.

Use wires long enough to cover the entire length.
