3.2 ERP PERFORMANCE DATA
3.2.1 General considerations
• This appliance must be installed, maintained and dismantled by professionals. Do not pour contained refrigerant into the
atmosphere since this refrigerant uid is a uorinated greenhouse gas regulated under European Regulation (EU) No 517/2014.
• Data with the mark (*) corresponds to the “Energy efciency contribution (η
S
)” due to the use of temperature control.
OTC control (Factory-supplied)
