If other antifreeze agents are used, they must be ethylene glycol
based. They must also have been approved by reputable companies in
the automotive industry (GM, Ford, Chrysler).
Example: DOWTHERM SR-1.
Concerning the electrical conductivity of the antifreeze and water
mixture, the antifreeze manufacturer's guidelines apply.
The water that is mixed with the antifreeze must strictly comply with the
defnition given in the Section "Definition of cooling water".
Use of other agents can shorten the service life.
Mixing different antifreeze agents is not permitted under any
circumstances.

Corrosion protection agent

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. +49-697934-410). Concentration of the
corrosion protection inhibitor in the cooling water 0.1 ... 0.14 %.
The cooling water should be checked 3 months after the first filling of
the cooling circuit and then once a year.
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.
