If the temperature is higher than 30°C and the humidity is higher
than RH80%, the thickness of the insulation materials should be at
least 20 mm to prevent condensation on the surface of the
insulation.
13.2 Connecting the refrigerant piping
DANGER: RISK OF BURNING/SCALDING
13.2.1 To connect the refrigerant piping to the
indoor unit
CAUTION
Install the refrigerant piping or components in a position
where they are unlikely to be exposed to any substance
which may corrode components containing refrigerant,
unless the components are constructed of materials that
are inherently resistant to corrosion or are suitably
protected against corrosion.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
▪ Pipe length. Keep refrigerant piping as short as possible.
▪ Flare connections. Connect refrigerant piping to the unit using
flare connections.
▪ Insulation. Insulate the refrigerant piping on the indoor unit as
follows:

2 Attach to the base of the unit.
3 Tighten the tie wrap on the insulation pieces.
4 Wrap the sealing pad from the base of the unit to the top
of the flare nut.
NOTICE
Make sure to insulate all refrigerant piping. Any exposed
piping might cause condensation.
14 Electrical installation
DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provides full
disconnection under overvoltage category III.
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.
14.1 Specifications of standard wiring
components
NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.
