4.2 Connecting the refrigerant piping
DANGER: RISK OF BURNING
4.2.1 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: FLAMMABLE MATERIAL
The R32 refrigerant (if applicable) in this unit is mildly
flammable. Refer to the outdoor unit specifications for the
type of refrigerant to be used.
▪ 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

1 Turn up the seams of the insulation pieces.
2 Attach to the base of the unit.
3 Tighten the cable ties 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.
4.3 Connecting the electrical wiring
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 provide 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.
