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".
▪ For intermediate A
room
values (i.e. when A
room
is
between two A
room
values from the table), consider the
value that corresponds to the lower A
room
value from the
table. If A
room
=8.5 m
2
, consider the value that
corresponds to "A
room
=8 m

".
