OMNIA ST 3.2
NOTE
For floor standing models, the value of "Installation height (H)" is considered 600 mm to comply to IEC 60335-2-40:2018 Clause GG2. For intermediate mc
values (i.e. when mc is between two values from the table), consider the value that corresponds to the higher mc value from the table. If m
value that corresponds to "m =2kg". Systems with total refrigerant charge lower than 1.84kg are not subjected to any room requirements.

For floor standing models, the value of "Installation height (H)" is considered 600 mm to comply to IEC 60335-2-40:2018 Clause GG2.
Based on the value of m (total refrigerant change of the system) use the subtable with the higher value, for instance if m

CAUTION
Frequency of Refrigerant Leakage Checks
For unit that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO
equivalent,at least every 12 months, or where a leakage detection system is installed, at least every 24 months.
For unit that contains fluorinated greenhouse gases in quantities of 50 tonnes of CO
equivalentat least every six months, or where a leakage detection system is installed, at least every 12 months.
For unit that contains fluorinated greenhouse gases in quantities of 500 tonnes of CO
where a leakage detection system is installed,at least every six months. Only certificated person is allowed to do installation, operation
and maintenance.
