The coolant level is too low. Check the cooling system for leaks and add more
coolant if needed.
3.3 Water quality
Subject to the equipment to be cooled or heat-balanced, certain requirements have to be met
by the cooling water regarding purity. The degree of the water`s contamination, as well as the
size and construction of the heat-exchanging- or -balancing plant determine the process most
suitable for the application of additives and/or care of the water-supply in question. You can
use normal tap water when filling the tanks.
With deviating water-quality, we recommend using the services of consultants, or to have a
water analysis or water sample sent to us.
Kemppi is not liable for any malfunctions or damages arising from deviating water qualities.
When employing chillers at temperatures below + 8°C, an anti-freeze medium must be added.
