6.5 Adding refrigerant
The units contain a basic quantity of refrigerant. In
addition, an additional amount of refrigerant must
be added for refrigerant piping lengths exceeding 5
metres per circuit. Refer to the following chart:
Up to and
incl. 5m
From 5m to
max. length
ML 263 DC
0 g/m 30 g/mML 353 DC
ML 523 DC
CAUTION!
Wear protective clothing when handling refrig-
erant.
DANGER!
Only refrigerant in a liquid state may be used to
fill the cooling cycle!
NOTICE!
Check the overheating to determine the refrig-
erant fill quantity.
NOTICE!
The escape of refrigerant contributes to cli-
matic change. In the event of escape, refrig-
erant with a low greenhouse potential has a
lesser impact on global warming than those
with a high greenhouse potential. This device
contains refrigerant with a greenhouse poten-
tial of 1975. That means the escape of 1 kg of
this refrigerant has an effect on global warming
that is 1975 times greater than 1 kg CO

on the refrigerant circuit or dismantle the
device - always enlist the help of qualified
experts.
