NOTE
For wall-mounted models, the “installation height (H)” is considered to be 1800 mm to be compliant with the IEC 60335-2-40 standard: 2018 clause GG2.
For intermediate Aroom values(i.e. when A
room
is between two values from the table), consider the value that corresponds to the lower A
room
value from the
table. If A
room
=3,6 m
2
, consider the value that corresponds to “A
room
=3,5 m
2
”.

NOTE
For wall-mounted models, the “installation height (H)” is considered to be 1800 mm to be compliant with the IEC 60335-2-40 standard: 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
c
=1,97kg, consider the value that corresponds to “m
c
=2kg”. Systems with total refrigerant charge lower than 1.84kg are not subjected to any room
requirements.

NOTE
For wall-mounted models, the “installation height (H)” is considered to be 1800 mm to be compliant with the IEC 60335-2-40 standard: 2018 clause GG2.
Based on the value of m
c
(total refrigerant change of the system) use the subtable with the higher value, for instance if m
c
= 2.05 kg use subtable m
c
= 2.1 kg
CAUTION
Frequency of Refrigerant Leakage Checks
For unit that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO
2
equivalent or more,but of less than 50
tonnes of CO
2
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
2
equivalent or more, but of less than 500
tonnes of CO
2
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
2
equivalent or more,at
least every three months, or where a leakage detection system is installed,at least every six months.
Only certificated person is allowed to do installation, operation and maintenance.
