Notes:
For H values lower than 0.6 m, the value of H is to be considered as 0.6 m to comply to IEC 60335-2-40:2018 Clause GG2.
For intermediate A
room
values, the value that corresponds to the lower A
room
value from the table is to be considered.
Example: For A
room
= 10.5 m², the value that corresponds to “A
room
= 10 m²” is to be considered.
Step B: Determine compliance of total oor area (A
room
+ B
room
) to minimum required total oor area
(A
min total
):
1. Calculate the oor area (B
room
) of the room adjacent to the installation room.
2. Determine the minimum required total oor area (A
min total
) based on the total refrigerant
charge (m
c
) as specied in Table II (see below).
3. If the total oor area of both rooms (A
room
+ B
room
) exceeds the minimum required total oor
area (A
min total
), proceed to Step C, to determine how large the ventilation openings between
the two rooms must be. If not, the unit must not be installed.

Notes:
For H values lower than 0.6 m, the value of H is to be considered as 0.6 m to comply to IEC 60335-2-40:2018 Clause GG2.
For intermediate m
c
values, the value that corresponds to the higher m
c
value from the table is to be considered.
Example: If m
c
= 1.85 kg, the value that corresponds to “m
c
= 1.86 kg” is to be considered.
Systems with total refrigerant charge lower than 1.84 kg are not subjected to any oor area requirements.
Charges above 2.27 kg are not allowed in the unit.
