Connections of units for outdoor installation must be additionally sealed (sealant not included).
If the outdoor unit will be switched off during the cold season, supply and extract air ducts (on the indoor side) must be
fitted with additional air shut-off dampers. These should prevent warm indoor air from circulating inside the unit when it is
stopped to avoid condensation, which may be detrimental to electronic components.

and applicable legal acts and safety requirements. Before installation of any electrical components:
• Make sure the unit is unplugged from the mains.
• If the unit has been standing in an unheated room for a long time, make sure there is no con-
densation inside and check if contacts and electronic parts of the connectors are not damaged
by moisture.
• Inspect the power cable ant other wiring for damage in insulation.
• Locate the wiring diagram for your unit according to the unit type.
