NOTICE
▪ Do NOT use gasoline, benzene, thinner polishing
powder or liquid insecticide. Possible consequence:
Discoloration and deformation.
▪ Do NOT use water or air of 50°C or higher. Possible
consequence: Discoloration and deformation.
▪ Do NOT scrub firmly when washing the blade with
water. Possible consequence: The surface sealing
peels off.
Clean with a soft cloth. If it is difficult to remove stains, use water or
neutral detergent.
7.3 About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Please contact your installer for more information.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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
▪ 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.
7.3.1 About the refrigerant leakage sensor
WARNING
It is necessary to replace the sensor after every detection
or at the end of the lifetime. Authorized person only MUST
replace the sensor.
NOTICE
Functionality of the safety measures are periodically
automatically checked. In case of malfunction, error code
will display on the user interface.
NOTICE
The R32 refrigerant leakage sensor is a semiconductor
detector which may incorrectly detect substances other
than R32 refrigerant. Avoid using chemical substances
(e.g. organic solvents, hair spray, paint) in high
concentrations, in the close proximity of the indoor unit
because this may cause misdetection of the R32
refrigerant leakage sensor.
INFORMATION
Lifetime of the sensor is 10 years. The user interface
displays error "
CH-05 " 6 months before the end of the
sensor lifetime and error " CH-02 " after the end of the
sensor lifetime. For more information refer to the reference
guide of the user interface and contact you dealer.
In case of detection when the unit is standby
When the detection occurs when the unit is standby, "false detection
check" will occur.
False detection check
1 Unit starts fan operation on the lowest setting.
2 User interface displays error code " A0-13 ", emits alarm sound
and status indicator is blinking.
3 Sensor checks if refrigerant leakage or misdetection occurred.
▪ If refrigerant leakage is NOT detected, Result: system returns to
normal operation after approximately 2 minutes.
▪ If refrigerant leakage is detected, Result:
1 User interface displays error " A0-11 ", emits alarm sound and
status indicator is blinking.
2 Contact your dealer immediately. For more information, see the
installation manual of the outdoor unit.
In case of detection when the unit is turned on
1 User interface displays error " A0-11 ", emits alarm sound and
status indicator is blinking.
2 Contact your dealer immediately. For more information, see the
installation manual of the outdoor unit.
INFORMATION
To stop alarm of the user interface see the reference guide
of the user interface.
INFORMATION
The minimum airflow during normal operation or during the
refrigerant leakage detection is always >240 m
3
/h.
8 Troubleshooting
If one of the following malfunctions occur, take the measures shown
below and contact your dealer.
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, electric shock or fire. Contact your dealer.
The system MUST be repaired by a qualified service person.
