Easytherm induction heaters are designed to heat rolling bearings. Our range of standard
heaters are designed to heat the workpiece to a maximum temperature of 240ºC (464°F). The
heater is designed to be used in an industrial environment with an ambient temperature of 0°C
to 40°C (32°F to 104°F) and an atmospheric humidity between 5% and 90%, non-condensing.
The induction heater is intended for indoor use only.
Bearings generally should only be heated to a maximum temperature of
120ºC (248ºF). Do not use induction heaters for bearings or workpieces with
dimensions outside the ranges specied in this manual. Do not switch o the
heater with the main switch while heating cycle is running.
INDUCTION HEATING1.
The operating instructions should always be followed when using an induction heater. TM
Induction Heating shall not be held liable for damages caused by improper handling or by use
which does not comply with the designated purpose. Prerequisites for the operator: He/she
must be authorised for use of the heater and must be familiar with the safety precautions. The
operator should have an understanding of the contents of this user manual, and be familiar with
safe workshop practices. Follow the user manual at all times.
In order to prevent danger or damage to the induction heater or workpiece, follow these
guidelines:
`All repairs must be carried out by an ocial TM Induction Heating distributor.
`Use original spare parts only.
`Protect the heater from water or very high humidity. Do not store (or use) the heater in
humid environments. The heater is designed for indoor use only. Place heater on a stable,
horizontal surface. Do not place the heater on a metal surface.
`Protect the heater core and yokes against corrosion, damage and deformation.
`Always place the temperature sensor on the workpiece to check the heating cycle. When
heating an object using Time Mode, the heating cycle must be checked using an external
temperature meter.
`Ensure that the induction heater operates at the correct supply voltage. If the heater is
not supplied with a (correct) plug, changes should only be made by a suitably qualied
electrician.
`Use proper handling equipment, appropriate for the weight of the workpiece and/or yoke.
Never support components with a metal cable or have any hanging in the proximity of the
magnetic eld. Extremely high currents can ow through the cable causing it to heat up
quickly, resulting in a risk of burning.

Remove all packing material and place the induction heater on a non-ferrous, stable, at
surface. Ensure that supply voltage, current and mains frequency meet the specications.
These can be found on the type plate at the back of the induction heater.
Each induction heater is provided with a plug, but there are a large number of plug
types. Should the plug not t your power supply, a suitable plug must be axed by a qualied
electrician. Voltages may dier for customized heaters.
Insert the plug into a shockproof wall socket and then connect the heater to mains electricity.
Turn main switch from 0 to 1. The LED display will light up and the induction heater is now
ready for use.

`The weight of the workpiece should not exceed the maximum weight as shown in the
heater specications on page 12 - TECHNICAL DATA. Exceeding these limits may result in
catastrophic equipment failure leading to personal injury.
`Ensure that the mains cable cannot come into contact with the work piece. Damage to the
cable may result in electrocution.
`Never support components with a metal cable or have any hanging in the proximity of the
magnetic eld. Extremely high currents can ow through the cable causing it to heat up
quickly, resulting in a risk of burning.
WORKPIECE SET-UP
Use appropriate hoisting equipment for heavy components and yokes. Manual
lifting of heavy objects is a common cause of injury. Wear safety shoes during
these procedures.
`Choose largest possible yoke which ts the diameter of the workpiece. Position the
workpiece onto the yoke and place the yoke with the machine milled surface on the poles
of the heater core.
`When heating a workpiece horizontally, always use the largest yoke available for the best
results.
`Always make sure that the workpiece avoids direct contact with the housing of the heater.
`When a heating cycle is completed, always wear heat-resistant gloves. The maximum
temperature of the workpiece on a standard induction heater is 240°C (464°F).
`Always treat yokes carefully. Falling, bumping, etc. can damage the yoke and/or cause
personal injury. Always store the yoke safely immediately after use.
`The heater can tilt when hanging a bearing
on a yoke opened too far (>45°). The
potential tilting point depends on bearing
weight, opening angle of yoke and the
position of the bearing (on the yoke).
Using a heavier workpiece may cause
the induction heater to tip over, causing
personal injury and damage to the heater.

`Always use the magnetic temperature sensor (hereafter referred to as the ‘sensor’) for
heating in Temperature Mode.
`Connect the sensor by inserting the plug into the socket at the front of the heater, with the
red dot facing upwards.
`Place the sensor on the workpiece, close to the bore (see g. 1). Make sure that the surface
used for the sensor is free of grease and/or oil. To avoid overheating the workpiece, never
place the sensor on the outer ring (see g. 2).
POSITIONING THE MAGNETIC TEMPERATURE SENSOR
Treat the magnetic temperature sensor with care. It is a valuable part of the
heater and can easily be damaged through careless handling. After use, we
suggest that it is placed on the side of the vertical pole.

OPERATION4.
When the operator switches the heater on, the LED display will show
110°C (230°F). With the buttons labeled UP and DOWN you can
increase or decrease the temperature. The temperature range for
Easytherm is from 0°C (32°F) to 240°C (484°F).
Select the preferred temperature and press the button labeled START/
STOP to start the heating process. The LED display will now show the
the measured temperature of the workpiece.
Once the selected temperature is reached, an acoustic signal can be
heard and the LED display will ash. Press the START/STOP-button to
stop the heating cycle and remove the temperature sensor from the
workpiece. Remove the workpiece from the induction heater. During
the heating cycle, the progress can be stopped at any moment by
pressing the START/STOP-button.
TEMPERATURE MODE Available on
Easytherm 1 / 2 / 3.5 / 15 /30
After heating cycle completion: As soon as the temperature drops 5°C/°F, the heating cycle will
automatically restart and heat until the selected temperature is reached (again). This process
will repeat for a maximum of 5 times. Press the START/STOP-button to stop the heating cycle.

TIME MODE
Time Mode should only be used in production areas where the
workpiece to be heated is always of the same specications. To
determine the settings for Time Mode, the operator must heat the
part on Temperature Mode rst. During the heating cycle measure the
time using a stopwatch. The measured time can now be used as input
for Time Mode. When heating an object using Time Mode, the heating
cycle must be checked using an external temperature meter.
When the operator switches the heater on, the display will show
110°C (230°F). Press the Time Mode-button and the LED display will
show 00.00. Select the preferred time duration and press the button
labeled START/STOP to start the heating process. The LED display will
now show the time remaining.
Once the selected time duration has passed the heating cycle will automatically stop, an acoustic
signal can be heard, and the LED display will ash. Press the START/STOP-button to stop the
acoustic signal. Remove the workpiece from the induction heater. During the heating cycle, the
progress can be stopped at any moment by pressing the START/STOP-button.
Our standard temperature sensors are suitable for operation up to a maximum
temperature of 240°C (464°F). The connection between magnet and
temperature sensor will break above the maximum temperature.
MAINTENANCE5.
`Store in a dry, frost-proof area, free from humidity.
`Keep clean with a soft, dry cloth.
`Keep the touchpad clean for optimal visibility of the user interface.
`Keep the contact parts of the heater core poles greased. Grease regularly with an acid-free
grease for optimal contact and to avoid corrosion (in the case of heaters with a pivoting
yoke, also grease the vertical pin regularly).
`CRITICAL SPARE PART - Magnetic temperature sensor. Always use original spare parts, we
can not guarantee a proper functioning using other parts.
Proper maintenance and handling practices are critical. Failure to follow
installation and maintenance instructions can result in equipment failure,
creating a risk of serious bodily harm.
