WARNING
13.1.3.3

Corrosion protection agent

NOTE
13-20
Use of other agents can shorten the service life.
Mixing different antifreeze agents is not permitted under any
circumstances.
We recommend the use of a corrosion protection inhibitor for the
cooling circuit, e.g. NALCO 00GE056 corrosion protection from
ONDEO Nalco (Nalco Deutschland GmbH, www.nalco.com,
D-60486 Frankfurt, Tel. +49-697934-0). Concentration of the corrosion
protection inhibitor in the cooling water 0.2 ... 0.25 %.
The cooling water should be checked 3 months after the first filling of
the cooling circuit and then once a year.
Control kits for testing the inhibitor concentration are available from
ONDEO Nalco.
Always observe the manufacturer's instructions when refilling the anti-
corrosion agent.
If any clouding, discoloration or bacteria are detected in the cooling
water, the cooling circuit has to be flushed out and refilled.
An inspection glass should be installed in the cooling circuit to be able
to monitor the cooling water easily.
