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

Refrigerant type: R410A

Global warming potential (GWP) value: 2087.5

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

Contact your installer for more information.

WARNING: MILDLY FLAMMABLE MATERIAL

The  R32  refrigerant  (if  applicable)  in  this  unit  is  mildly
flammable.  Refer  to  the  outdoor  unit  specifications  for  the
type of refrigerant to be used.

WARNING

The  appliance  using  R32  refrigerant  shall  be  stored  so  as
to  prevent  mechanical  damage  and  in  a  well-ventilated
room  without  continuously  operating  ignition  sources  (e.g.
open  flames,  an  operating  gas  appliance,  or  an  operating
electric heater). The room size shall be as specified in the
General safety precaution.

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

▪ R410A  is  a  non-combustible  refrigerant,  and  R32  is  a

mildly  flammable  refrigerant;  they  normally  do  NOT
leak. If the refrigerant leaks in the room and comes into
contact  with  fire  from  a  burner,  a  heater,  or  a  cooker,
this  may  result  in  a  fire  (in  case  of  R32),  or  the
formation of a harmful gas.

▪ Turn  OFF  any  combustible  heating  devices,  ventilate

the  room,  and  contact  the  dealer  from  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.

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,  electrical  shock  or  fire.  Contact  your
dealer.

The system MUST be repaired by a qualified service person.
