2 Specific installer safety instructions
Charging refrigerant (see "16 Charging
WARNING
▪ The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the
formation of a harmful gas.
▪ Turn OFF any combustible heating devices, ventilate
the room, and contact the dealer where you purchased
the unit.
▪ Do NOT use the unit until a service person confirms
that the part from which the refrigerant leaked has been
repaired.
WARNING
Charging of refrigerant MUST be in accordance with the
instructions from this
refrigerant" [ 4 36].
WARNING
▪ Only use R32 as refrigerant. Other substances may
cause explosions and accidents.
▪ R32 contains fluorinated greenhouse gases. Its global
warming potential (GWP) value is 675. Do NOT vent
these gases into the atmosphere.
▪ When charging refrigerant, ALWAYS use protective
gloves and safety glasses.
Electrical installation (see "17 Electrical
WARNING
Electrical wiring MUST be in accordance with the
instructions from:
▪ This manual. See "17 Electrical
▪ The wiring diagram, which is delivered with the unit,
located at the inside of the service cover. For a
translation of its legend, see
unit" [ 4 62].
Outdoor
WARNING
The appliance MUST be installed in accordance with
national wiring regulations.
CAUTION
Do NOT push or place redundant cable length into the unit.
WARNING
▪ If the power supply has a missing or wrong N-phase,
equipment might break down.
▪ Establish proper earthing. Do NOT earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earthing may cause electrical shocks.
▪ Install the required fuses or circuit breakers.
▪ Secure the electrical wiring with cable ties so that the
cables do NOT come in contact with sharp edges or
piping, particularly on the high-pressure side.
▪ Do NOT use taped wires, extension cords, or
connections from a star system. They can cause
overheating, electrical shocks or fire.
▪ Do NOT install a phase advancing capacitor, because
this unit is equipped with an inverter. A phase
advancing capacitor will reduce performance and may
cause accidents.

WARNING
The electrical components shall only be replaced with parts
specified by the appliance manufacturer. Replacement with
other parts may result in the ignition of refrigerant in the
event of a leak.
WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
▪ When connecting the power supply: connect the earth
cable first, before
connections.
▪ When disconnecting the power supply: disconnect the
current-carrying cables first, before separating the earth
connection.
▪ The length of the conductors between the power supply
stress relief and the terminal block itself MUST be as
such that the current-carrying wires are tautened before
the earth wire is in case the power supply is pulled
loose from the stress relief.
