 At higher temperatures vaporisation losses occur. In this case use a bath cover.

Only use distilled water or fully demineralized high purity water after adding 0.1 g of soda (Na
carbonate) per liter of water. Otherwise there is the risk of corrosion!
 Water content falls with longer operation at high temperatures. The mixture becomes flammable (flash point
119 °C). Check the mixture ratio with a hydrometer.
 With the selection of the heat transfer liquid it should be noted that impairment of the properties is to be
expected at the lower limit of the temperature range due to increasing viscosity. Therefore, only make maxi-
mum use of temperature ranges when essential.
 Application ranges of heat transfer liquids and hoses are general figures, which may be restricted by the oper-
ating temperature range of the units.
With silicone rubber, silicone oils lead to substantial swelling. Never use silicone oil with silicone hoses!
