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
equivalent.
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manual might be outdated.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. There is a
dedicated place for it on the wiring diagram label.

Connecting the electrical wiring
DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several
minutes during normal operation for "defrosting the unit", or
when in "thermostat stop" operation.

NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
1 Remove the service cover.
2 Connect the interconnection cables and power supply as
follows:
