Installation site (see "4.1 Preparing the installation site" [ 4 6])
CAUTION
▪ Check if the installation location can support the unit's
weight. Poor installation is hazardous. It can also cause
vibrations or unusual operating noise.
▪ Provide sufficient service space.
▪ Do NOT install the unit so that it is in contact with a
ceiling or a wall, as this may cause vibrations.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
Connecting the refrigerant piping (see "5.2 Connecting the
refrigerant piping" [ 4 8])
CAUTION
▪ No brazing or welding on site for units with R32
refrigerant charge during shipment.
▪ During installation of the refrigeration system, joining of
parts with at least one part charged shall be performed
taking into account the following requirements: inside
occupied spaces non-permanent joints are NOT
allowed for R32 refrigerant except for site made joints
directly connecting the indoor unit to piping. Site made
joints directly connecting piping to indoor units shall be
of non-permanent type.
NOTICE
▪ Use the flare nut fixed to the unit.
▪ To prevent gas leakage, apply refrigeration oil ONLY to
the inside of the flare. Use refrigeration oil for R32.
▪ Do NOT reuse joints.
NOTICE
▪ Do NOT use mineral oil on flared part.
▪ Do NOT reuse piping from previous installations.
▪ NEVER install a drier to this R32 unit to guarantee its
lifetime. The drying material may dissolve and damage
the system.
WARNING
Connect the refrigerant piping securely before running the
compressor. If the refrigerant piping is NOT connected and
the stop valve is open when the compressor is run, air will
be sucked in. This will cause abnormal pressure in the
refrigeration cycle, which may result in equipment damage
and even injury.
NOTICE
▪ Incomplete flaring may cause refrigerant gas leakage.
▪ Do NOT re-use flares. Use new flares to prevent
refrigerant gas leakage.
▪ Use flare nuts that are included with the unit. Using
different flare nuts may cause refrigerant gas leakage.
CAUTION
Do NOT open the valves before flaring is complete. This
would cause refrigerant gas leakage.
DANGER: RISK OF EXPLOSION
Do NOT start the unit if it is vacuumed.

2 Specific installer safety instructions
Charging refrigerant (see "6 Charging refrigerant" [ 4 9])
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
▪ 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.
NOTICE
To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
WARNING
NEVER directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.
Electrical installation (see "7 Electrical installation" [ 4 10])
WARNING
Appliance MUST be installed in accordance with national
wiring regulations.
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
legislation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST comply
legislation.
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 shock.
▪ 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, stranded conductor wires,
extension cords, or connections from a star system.
They can cause overheating, electrical shock 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.
