and firmly tighten.
IMPORTANT:
Make ground connection prior to any other electrical
connections.
• Make electrical connections between units prior to proceeding to
mains supply unit connection.
• 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.
• Ensure that each mains supply connection has been made
through a switch with contact gap of at least 3 mm.
• The mains supply connecting cable must be H07 RNF
(245IEC57) or higher type, synthetic rubber insulation with
Neoprene coating, according to
EN 60335-2-40 codes.
• The electric cable connecting the indoor unit to the outdoor unit
must be of A05 RN-F type (245IEC57) (or higher) with synthetic
rubber insulation and neoprene coating according to the EN
60335-2-40 standards.
• Make certain the refrigerant pipes and the electrical
connection lines between the indoor unit and the outdoor
unit have the same colours and reference codes (A, A1, A2,
B, B1, B2) using the special adhesive references supplied.
