6 Electrical installation

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

DANGER: RISK OF ELECTROCUTION
WARNING
Rotating fan. Before powering ON the outdoor unit, make
sure that the discharge grille covers the fan as protection
against a rotating fan. See
grille" [ 4 11].
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
Do NOT push or place redundant cable length in the unit.
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50 mm.
