Checking and replacing the impressed current anode (if
required)
1.
Check impressed current anode
G
for damage (see page 41).
2.
If required, remove impressed cur-
rent anode
G
from flange lid
E
and fit a new electrode.

Please note
To safeguard the protective
effect ensure during installa-
tion, that impressed current
anode
G
has no contact
with the internal indirect coil.
After the installation, check
the resistance between
cable
C
and anode con-
nection
D
–
the resistance
must go towards infinity.
3.
Push cable
C
onto anode connec-
tion
D
.
4.
Open the on-site shut-off valve and
check for leaks.
5.
Install thermal insulation hood
B
.
Checking the diaphragm expansion vessel and heating cir-
cuit pressure
Note
Carry out this test on a cold system.
1.
Drain the system or close the cap
valve on the diaphragm expansion
vessel and reduce the pressure
until the pressure gauge indicates
"0".
