WARNING
Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:
▪ Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.
▪ Toxic gas may be produced if refrigerant gas comes
into contact with fire.
WARNING
Always recover the refrigerants. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.

Electrical

DANGER: RISK OF ELECTROCUTION
▪ Turn OFF all power supply before removing the
switch box cover, connecting electrical wiring or
touching electrical parts.
▪ Disconnect the power supply for more than 1 minute,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage must be less than 50 V DC before you can
touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
WARNING
If not factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, shall be installed in the fixed wiring.
WARNING
▪ Only use copper wires.
▪ 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 electric 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.
