IMPORTANT
During functioning in heat pump heating mode, the unit performs defrost cycles to eliminate any ice that might
form at low temperatures inside the outdoor unit
!
Refrigerant charge check
This check becomes necessary after any refrigerant leak
or after replacement of the compressor.The best method
to correctly charge refrigerant is to completely empty the
refrigerant circuit using refrigerant recovery equipment.
Then charge the exact quantity of refrigerant according
to the data shown on the unit nameplate and always
considering the additional charges listed on the charge
sheet.
R-410A systems must be charged with liquid refrigerant. Use
the special recharging equipment (normally on the market)
to control the refrigerant correctly.
!
IMPORTANT
Any works carried out on the refrigerant circuit
must be undertaken by a person holding the
relevant Fgas certification
