NOTICE

Make  sure  to  open  the  stop  valves  after  installing  the
refrigerant  piping  and  performing  vacuum  drying.  Running
the  system  with  the  stop  valves  closed  may  break  the
compressor.

Charging refrigerant

4.4.1

To determine the additional refrigerant
amount

To determine if adding additional refrigerant is necessary

If

Then

L1 ≤ chargeless length

L1 (m)

Chargeless length=

▪ 10 m (size‑down)

▪ 30 m (standard)

▪ 15 m (size‑up)

You do not have to add
additional refrigerant.

L1 > chargeless length

You must add additional
refrigerant.

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

INFORMATION

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

4.4.2

To determine the complete recharge
amount

When  piping  length  is  <5  m,  a  complete  recharge  of  the  unit  is
required.

Charging refrigerant: Setup

See 

"4.3.1 Checking refrigerant piping: Setup" on page 6

.

4.4.4

To charge additional refrigerant

WARNING

▪ Only use R410A as refrigerant. Other substances may

cause explosions and accidents.

▪ R410A  contains  fluorinated  greenhouse  gases.  Its

global  warming  potential  (GWP)  value  is  2087.5.  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  both  the  service  port  of  the
gas stop valve and the service port of the liquid stop valve.

2

Charge the additional refrigerant amount.

3

Open the stop valves.

4.4.5

If a multilingual fluorinated greenhouse gases label is
delivered with the unit (see accessories), peel off the
applicable language and stick it on top of

e

Quantity of fluorinated greenhouse gases

 of the total

refrigerant charge expressed as tonnes CO

 equivalent.

f

GWP = Global warming potential

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.  That  GWP  is  based  on  the  current  legislation  on
fluorinated greenhouse gases. The GWP mentioned in the
manual might be outdated.

2

Fix  the  label  on  the  inside  of  the  outdoor  unit.  There  is  a
dedicated place for it on the wiring diagram label.
