Notes: 1. Outdoor unit is suitable for outdoor installation.
2. Wire size shown applies to line length up to 15 m.
3. 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.
4. The mains supply connecting cable must be H07 RN-F type (245 IEC 57) or higher, with synthetic rubber insuluation with Neoprene coating,
according to EN 60335-2-40 codes.
The mains supply must be connected to the indoor unit.
• Open control box panel (valve cover panel).
• Make electrical connections between units prior to proceeding
to mains supply unit connection.
• Connect the wires to the terminals according to the wiring
diagram and firmly tighten.
• Before proceeding with the unit connection to the mains supply
locate live L and neutral N, then make connections as shown
in the wiring diagram.
• Check that the impedance of the mains power supply is in
conformance with the unit power input indicated on the electric
data table IV.
• Ensure that mains supply connection is made through a switch
that disconnects all poles, with contact gap of a least 3 mm.
• The indoor - outdoor unit interconnecting wires 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.
• The mains supply connecting cable, 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.™
