WARNING
If appliances contain R32 refrigerant, then the floor area of
the room in which the appliances are installed, operated
and stored must be larger than the minimum floor area.
This applies to:
▪ Indoor units without refrigerant leakage sensor; in
case of indoor units with refrigerant leakage sensor,
consult the installation manual
▪ Outdoor units installed or stored indoors (example:
winter garden, garage, machinery room)
▪ Field piping in unventilated spaces
NOTICE
▪ Pipework shall be protected from physical damage.
▪ Installation of pipework shall be kept to a minimum.
CAUTION
The total refrigerant charge in the system cannot exceed
the requirements for minimum floor area of the smallest
room that is served. For minimum floor area requirements
for indoor units, see the installation and operation manual
of the outdoor unit.
WARNING
▪ The area MUST be checked with an appropriate
refrigerant detector prior to and during work, to ensure
the technician is aware of potentially toxic or flammable
atmospheres.
▪ Ensure that the leak detection equipment being used is
suitable for use with all applicable refrigerants, i.e. non-
sparking, adequately sealed or intrinsically safe.
▪ Prior to and during work, the area MUST be checked
with an appropriate refrigerant detector capable of
detecting R32 refrigerant,
environment free of refrigerant.
WARNING
Do NOT apply any permanent inductive or capacitance
loads to the circuit without ensuring that this will NOT
exceed the permissible voltage and current permitted for
the equipment in use.

WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable
legislation.
▪ All field wiring MUST be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do NOT come in contact with the piping and sharp
edges. Make sure no external pressure is applied to the
terminal connections.
▪ Make sure to install earth wiring. Do NOT earth the unit
to a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
▪ Make sure to use a dedicated power circuit. NEVER
use a power supply shared by another appliance.
▪ Make sure to install the required fuses or circuit
breakers.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electrical shock or fire.
▪ When installing the earth leakage protector, make sure
it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
