INFORMATION
▪
H = Height measured from the bottom of the casing to the floor.
▪
For intermediate H values (i.e. when H is between two H values from the table),
consider the value that corresponds to the lower H value from the table. If
H=1450 mm, consider the value that corresponds to "H=1400 mm".
▪
Systems with a total refrigerant charge (m
<27 m) are NOT subjected to any requirements to the installation room.
▪
Charges >1.9 kg are NOT allowed in the unit.

For intermediate H values (i.e. when H is between two H values from the table),
consider the value that corresponds to the lower H value from the table. If
H=1450 mm, consider the floor area that corresponds to "H=1400 mm".
▪
For intermediate dm values (i.e. when dm is between two dm values from the
table), consider the value that corresponds to the higher dm value from the table.
If dm=1.55 kg, consider the value that corresponds to "dm=1.6 kg".
