Allowable refrigerant charge
The calculation of the allowable refrigerant charge depends on the combination of
the "access category" and the "location classification" as described in the following
table.
INFORMATION

requirements apply. If occupied spaces are isolated, e.g. by sealed partitions, floors
and ceilings, the requirements of the individual access category apply.
