FXMA-A
VRV system air conditioner
3P680922-1A – 2022.01

CAUTION

After a long use, check the unit stand
and fitting for damage. If damaged, the
unit may fall and result in injury.

CAUTION

Before accessing terminal devices,
make sure to interrupt all power supply.

DANGER: RISK OF
ELECTROCUTION

To clean the air conditioner or air filter,
be sure to stop operation and turn all
power supplies OFF. Otherwise, an
electrical shock and injury may result.

WARNING

Be careful with ladders when working
in high places.

DANGER: RISK OF
ELECTROCUTION

Disconnect the power supply for more
than 10 minutes, 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
warning label for persons performing
service and maintenance.

CAUTION

Turn off the unit before cleaning the air
filter and air outlet.

WARNING

Do NOT let the indoor unit get wet.

Possible consequence: 

Electrical

shock or fire.

About the refrigerant (see 

"7.3 About the refrigerant"

 [

 12])

WARNING: MILDLY FLAMMABLE
MATERIAL

The refrigerant inside this unit is mildly
flammable.

WARNING

▪ Do NOT pierce or burn refrigerant

cycle parts.

▪ Do NOT use cleaning materials or

means to accelerate the defrosting
process other than those
recommended by the manufacturer.

▪ Be aware that the refrigerant inside

the system is odourless.

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

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).

WARNING

The R32 refrigerant leakage sensor
must be replaced after every detection
or at the end of its lifetime. ONLY
authorised persons may replace the
sensor.

Troubleshooting (see 

"8 Troubleshooting"

 [

WARNING

Stop operation and shut OFF the
power if anything unusual occurs
(burning smells etc.).

Leaving the unit running under such
circumstances may cause breakage,
electrical shock or fire. Contact your
dealer.
