Connect the wires to the terminals according to the wiring diagram
and firmly tighten them.
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 mains supply connection is made through a switch
that disconnects all poles, with contact gap of a least 3 mm.
• The cables must be H07 RN-F type, for mains supply and for
interconnecting wires.
The above mentioned cables must have synthetic rubber
insulation with Neoprene coating, according to EN 60335-2-40
and HD277.S1 codes.
• The terminal block label refers to indoor unit A4.
This only refers to model 38VYM-32.
• 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
(A1, A2, A3, A4) using the special adhesive references
supplied.
