Heat transfer liquid
The device is designed exclusively for non-combustible heat transfer liq-
uids according to class I as per DIN 12876-1.
The use of heat transfer liquids poses a risk of injury from high and low
temperatures if certain upper or lower temperature thresholds are
exceeded or the external application is broken and a reaction is initiated
with the heat transfer liquid.
All possible risks in handling the heat transfer liquid are specified in the
safety data sheet for the liquid together with corresponding safety
measures. The safety datasheet must therefore be observed in order to
use the device as intended.
