Requirement
Replenish only coolant of the same manufacturer having the same
specification. Mixing different coolants may lead to corrosion of the
cooling system and degradation of the coolant. The glycol content
must be min. 25%.
When switching the coolant to another product or changing the
manufacturer, the cooling system must be completely flushed and
cleaned with this coolant. When preparing the coolant from
concentrate and water, be sure to use demineralized water only. Only
then the machine may be put back into operation.

The information given in the Technical Data of the cooling water apply at an ambient
temperature of max. 40 °C.
The values specified in the table must absolutely be observed!
Deviating from these values will not ensure sufficient cooling of the
machine.
The maximum operating pressure must not exceed 8 bar!
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
Be sure to replenish with a ready-mix. Mixing different glycol alkalis
may trigger chemical reactions causing agglutination or clumping of
the coolant.
Procedure
1. Check coolant. Test criteria for this visual inspection are the clarity and
transparency of the coolant.
2. Check filling level on the level indicator.
