Typical  workflow  –  Completely  recharging  refrigerant  typically
consists of the following stages:

1 Determining how much refrigerant to charge.

2 Charging refrigerant.

3 Filling in the fluorinated greenhouse gases label, and fixing it to

the inside of the outdoor unit.

6.6.2

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

WARNING: 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  from  which  you  purchased
the unit.

Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.

6.6.3

Precautions when charging refrigerant

INFORMATION

Also  read  the  precautions  and  requirements  in  the
following chapters:

▪ General safety precautions

▪ Preparation

To determine the additional refrigerant
amount

To determine if adding additional refrigerant is necessary

If

Then

(L1+L2+L3+L4+L5+L6+L7)≤
30 m (chargeless length)

You do not have to add
additional refrigerant.

(L1+L2+L3+L4+L5+L6+L7)>
30 m (chargeless length)

You must add additional
refrigerant.

For future servicing, encircle the
selected amount in the tables
below.
