INFORMATION
▪
For HPSU models, the value of "Installation height (H)" is considered 600 mm to
comply to IEC 60335-2-40:2013 A1 2016 Clause GG2.
▪
For intermediate A
room
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
=12.5 m
2
, consider the value that corresponds to "A
room
=12 m
2
".

is between two values from the table),
consider the value that corresponds to the higher m
c
value from the table. If
m
c
=1.87 kg, consider the value that corresponds to "m

=1.88 kg".
▪
Systems with a total refrigerant charge (m
c
) <1.84 kg (i.e. if the piping length is
<27 m) are NOT subjected to any requirements to the installation room.
▪
Charges >1.9 kg are NOT allowed in the unit.
