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.

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  "

",  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.

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

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.
