To determine the additional refrigerant amount (R in kg) (in
case of twin, triple and double twin)

Determine R1 and R2.

Then

G1>30 m

Use the table below to determine
R1

G1≤30 m

(and G1+G2>30 m)

R1=0.0 kg.

Use the table below to determine
R2.

RZASG100

Case: Twin, standard liquid pipe size

1 G1 Total Ø9.5

=> G1=35 m

G2 Total Ø6.4 => G2=7+5=12 m

2 Case: G1>30 m

R1 Length=G1−30 m=5 m

=> R1=0.35 kg

R2 Length=G2=12 m

=> R2=0.4 kg

3 R

R=R1+R2=0.35+0.4=0.75 kg

RZASG125

Case: Triple, standard liquid pipe size

1 G1 Total Ø9.5 => G1=5 m

G2 Total Ø6.4 => G2=15+12+17=44 m

2 Case: G1≤30 m (and G1+G2>30 m)

R1 R1=0.0 kg

R2 Length=G1+G2−30 m =

5+44−30=19 m

=> R2=0.4 kg

Charging refrigerant: Setup

See

"6.5.3 Checking refrigerant piping: Setup" on page 16

6.6.8

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.

CAUTION

To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.

Prerequisite:

Before charging refrigerant, make sure the refrigerant

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

Connect the refrigerant cylinder to both the service port of the
gas stop valve and the service port of the liquid stop valve.

Charge the additional refrigerant amount.

Open the stop valves.

If pump down is needed in case of dismantling or relocating the
system, see

"11.3 To pump down" on page 26

for more details.

6.6.9

To activate/deactivate the vacuum mode
field setting

Description

To  perform  vacuum  drying  or  a  complete  recharge  of  the  outdoor
unit’s  internal  refrigerant  piping  it  is  necessary  to  activate  the
vacuum  mode  which  will  open  required  valves  in  the  refrigerant
circuit  so  the  vacuuming  process  or  recharge  of  refrigerant  can  be
done properly.

To activate vacuum mode:

Activating the vacuum mode is done by operating the push buttons
BS* on the PCB (A1P) and reading the feedback from the 7‑segment
displays.

Operate the switches and push buttons with an insulated stick (such
as a closed ball-point pen) to avoid touching of live parts.

When the unit is powered on and not running, hold down the
BS1 pushbutton for 5 seconds.

Result:

You will reach the setting mode, the 7 segment display

will show '2 0 0'.

Press the BS2 button until you reach page

2–28

When

2–28

is reached, press the BS3 button once.
