Checking the sacrificial an-
odes
IMPORTANT!
Corrosion of sacrificial anodes depends on the
operating environment. Therefore, check the
sacrificial anodes every third month during the
first year of commissioning or when changing
the operating environment.
1. Drain the sea water circuit as described in the
Draining the sea water circuit
section.
2. Remove all sacrificial anodes.
3. Check all sacrificial anodes:
– Scrape off all loose material and check the
corrosion.
– Renew all sacrificial anodes if there is less
than ¾ (2) remaining of any of the sacrifi-
cial anodes.
– If the sacrificial anodes are very corroded
(3), the length of the intervals for checking
the sacrificial anodes should be halved. If
the sacrificial anodes are very corroded,
they often come loose entirely.
4. Renew the gasket when fitting.
