Safety features
• The heater will switch off automatically if the ambient temperature
exceeds 70ºC (158ºF).
• When using the temperature mode, the heater will switch off automati-
cally if the rate of temperature rise is too low.
• On models equipped with a swing arm, the arm can be fixed in the open
position.
An induction heater works due a magnetic field. In the table below are
there are some measured values of the flux density in milliTesla (mT). These
values are measured in different radii and heights around the heater. These
measurements can be used as a guide in conforming to local regulations
regarding the maximum time exposure of people to magnetic fields.
The values below are only valid for this combination of bearing type and
yoke bar.
Different configurations may give different values. Due to the large variety
of bearing types in combination with the different yoke bars it is impos-
sible for us to give every possible value.
