2.6. General safety instructions
The following safety instructions are given for the heating device:
DANGER
Damaged or awed electrical connections or unlicensed hot
components lead to heavy injuries or even death.
• All work on electrical connections shall be provided by qualied
personnel only.
• Immediately change damaged cables or plugs.
DANGER
Never use the heating device in potentially explosive areas.
WARNING
The heating device generates a magnetic eld that can cause inter-
ference with pacemakers and electronic devices such as wrist-
watches.
• Electronic devices and persons with pacemakers must keep a safe
distance of 5 metres during operation.
CAUTION
Risk of injury from heated individual parts.
• Keep a safety distance of 50 cm from the workpiece and the heating
tower during the heating process.
• Use heat-resistant gloves when handling the workpiece.
NOTICE
Moisture can damage the heating device.
• Never expose the heating device to high levels of humidity.
• Do not immerse the unit in water or other liquids.

3. Description of function
3.1. Design
IND 220 is suitable for mounting all ring-shaped metal parts (e.g. rolling bearings, gear wheels,
anges and pulleys) that are mounted on shafts with press tension. As with an induction cooker, a
magnetic eld is generated in the medium frequency range, which induces a voltage in the inner
ring of the workpiece. The eddy currents thus generated heat the workpiece and expand it so that
it can be mounted on the shaft without applying force. All components of the heater remain cold.
All workpieces to be heated must be made of magnetic metals. This property can be easily checked
by means of the temperature probe supplied.
