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.

WARNING

NEVER  directly  touch  any  accidental  leaking  refrigerant.
This could result in severe wounds caused by frostbite.

6.2

To determine the additional
refrigerant amount

If the total liquid

piping length is…

Then…

≤10 m

Do NOT add additional refrigerant.

>10 m

R=(total length (m) of liquid
piping⁠–⁠10 m)×0.020

R=Additional charge (kg) (rounded in units
of 0.01 kg)

INFORMATION

Piping length is the one-way length of liquid piping.

6.3

To determine the complete
recharge amount

INFORMATION

If  a  complete  recharge  is  necessary,  the  total  refrigerant
charge  is:  the  factory  refrigerant  charge  (see  unit  name
plate) + the determined additional amount.

6.4

To charge additional refrigerant

WARNING

▪ Only  use  R32  as  refrigerant.  Other  substances  may

cause explosions and accidents.

▪ R32  contains  fluorinated  greenhouse  gases.  Its  global

warming  potential  (GWP)  value  is  675.  Do  NOT  vent
these gases into the atmosphere.

▪ When  charging  refrigerant,  ALWAYS  use  protective

gloves and safety glasses.

Prerequisite: 

Before charging refrigerant, make sure the refrigerant

piping is connected and checked (leak test and vacuum drying).

1

Connect the refrigerant cylinder to the service port.

2

Charge the additional refrigerant amount.

3

Open the gas stop valve.

6.5

gases label

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

Use  the  GWP  value  mentioned  on  the  refrigerant  charge
label.

2

Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.

Electrical installation

DANGER: RISK OF ELECTROCUTION

WARNING

▪ All  wiring  MUST  be  performed  by  an  authorised

electrician  and  MUST  comply  with  the  applicable
legislation.

▪ Make electrical connections to the fixed wiring.

▪ All  components  procured  on-site  and  all  electrical

construction  MUST  comply  with  the  applicable
legislation.

WARNING

Appliance  shall  be  installed  in  accordance  with  national
wiring regulations.

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

Use  an  all-pole  disconnection  type  breaker  with  at  least
3  mm  between  the  contact  point  gaps  that  provide  full
disconnection under overvoltage category III.

WARNING

If the supply cord is damaged, it MUST be replaced by the
manufacturer,  its  service  agent  or  similarly  qualified
persons in order to avoid a hazard.

WARNING

Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.
