
When using Kryo 30:
The water content decreases during longer periods of operation at
higher temperatures and the mixture becomes combustible (flash point
119°C). Check the mixing ratio using a hydrometer.

When using Aqua 90:
Evaporation losses occur at higher temperatures. In this case, use a bath
cover.

Never use silicone oil in silicone tubes.

When using mineral oils:
Do not use in combination with an EPDM hose.

The proportion of alkaline earth ions in the water must be between
0.71 mmol/L and 1.42 mmol/L (equivalent of 4.0 and 8.0 °dH). Harder
water leaves limescale deposits in the device.

The pH value of the water must be between 6.0 and 8.5.

Distilled, deionized and demineralized water are unsuitable due to their
reactivity. High-purity water and distillates are suitable as a heat transfer
liquid after 0.1 g of soda (Na
2
CO
3
, sodium carbonate) is added for every
liter of water.

Sea water is unsuitable due to its corrosive properties.

Avoid chlorine content in the water at all costs. Do not add chlorine
to the water. Cleaning agents and disinfectants, for example, contain
chlorine.

The water must be free of impurities. Water with iron content is unsuit-
able due to rust formation and untreated river water is unsuitable due to
algae growth.

The addition of ammonia is not permitted.
