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.
4.5.3 To fix the fluorinated greenhouse gases

1 Fill in the label as follows:
Contains fluorinated greenhouse gases

a 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 a.
b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Quantity of fluorinated greenhouse gases of the total
refrigerant charge expressed as tonnes CO
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
Formula to calculate the quantity in CO
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manual might be outdated.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 near the gas and
liquid stop valves.
