▪

Remove the batteries from the user interface (if applicable).

10.4 Maintenance after a long stop period

E.g., at the beginning of the season.

▪

Check  and  remove  everything  that  might  be  blocking  inlet  and  outlet  vents  of
indoor units and outdoor units.

▪

Clean air filters and casings of indoor units (see

air filter and suction grille"

 [

4

 34]).

▪

Insert batteries in the user interface (if applicable).

▪

Turn on the power at least 6 hours before operating the unit in order to ensure
smoother  operation.  As  soon  as  the  power  is  turned  on,  the  user  interface
display appears.

10.5 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.
