5 Confirm that all hangers are fixed.
6 In case of bottom suction, close the air inlet grille. In case of
rear suction, close service duct opening.
7 Turn ON the power.
8 To remove warning screens, see the reference guide of the
user interface.
7.2.2 To clean the air outlet
WARNING
Do NOT let the indoor unit get wet. Possible
consequence: Electric shock or fire.
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.
Clean with a soft cloth. If it is difficult to remove stains, use water or
a 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.
