Follow the safety instructions to avoid personal injury and property damage. Also, the
valid safety instructions for workplaces must be followed.
• Only connect the unit to a power socket with an earthing contact (PE – protective
earth)!

• Set the excess temperature safety installation at least 25 °C below the fire point of
the bath fluid.
• Observe the limited working temperature range when using plastic bath tanks.
• Never operate the unit without bath fluid in the bath.
• Pay attention to the thermal expansion of bath oil during heating to avoid
overflowing of the fluid.
