FILLING AND WATER REPLACEMENT
Fill the cooling unit with distilled water and add the additives (the kit is pre-dosed and a safety handling manual is
included).
Notice
The conductivity of the water must not exceed 1000 μS. This value will not be reached if mixing the
distilled water and additive accurately. A conductivity meter is available on request from Trotec Laser
GmbH.
Water replacement must be carried out once a year. Empty the cooling unit, clean it with distilled water, fill it with fresh
distilled water and add new additives.
Notice
In case of extremely strong impurities the additive *Nalco CCL2567 is recommended for the cleaning rinse.
