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.
When using Ultra 350:

Do not use in combination with an EPDM hose.
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
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.
