SmartTEMP induction heaters are used to heat rolling bearings. Other metal components forming a closed circuit such
as bushings, shrink rings, pulleys and gears can also be heated. This will facilitate mounting where an interference
fit is required.
Our range of standard heaters are designed to heat the workpiece to a maximum temperature of 240ºC (464°F).
The heaters can be used on a continuous basis. 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.
Bearings generally should only be heated to a maximum temperature of 110ºC (230ºF).
Do not use induction heaters for bearings or workpieces with dimensions outside the ranges specified
in this manual. Do not switch off the heater with the main switch while heating cycle is running.
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.

SAFETY GUIDELINES
The operating instructions should always be followed when using an induction heater.
NTN-SNR Roulements 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.
`Since a magnetic field 4&5 is generated by the induction heater, people wearing a pacemaker 1or other
implant device 2should not work or be in the immediate vicinity of the device. Other sensitive equipment
such as wrist watches, magnetic carriers, electronic circuits, etc.
3might also be affected. The safety
distance is 1 metre (38”).
`Use safety gloves as protection against burns to hands. The gloves 7delivered are suitable for use up to
temperatures of 240°C (464°F) (resistant to contact heat only).
`Hot surface, avoid contact 6.
`Do not operate an induction heater in areas where there is risk of explosion.
`Wear safety shoes 8.
In order to prevent danger or damage to the induction heater or workpiece, follow these guidelines:
`All repairs must be carried out by an official repair center.
`Use original spare parts only.
`Protect the heater from water or very high humidity during storage.
`Protect the heater core and yokes against corrosion, damage and deformation.
`Only preheat bearings to max. 110°C (230°F).
`To ensure proper operation of the device, it is important to provide the device with the latest software
updates. A description can be found in chapter OPERATION - USER MENU.

SAFETY INSTRUCTIONS
` The user should have an appreciation of the contents of this user manual, and be familiar with safe
workshop practices.
`Follow the user manual at all times.
`Ensure that the induction heater operates at the correct supply voltage. If the heater is not supplied with

Should an error occur during the heating process, the induction heater will automatically stop. The corresponding error will
be displayed on screen. In the case of user error, the display indicates what steps are to be taken to correct the problem.
More information about the types of errors can be found in chapter ERRORS.
An induction heater produces an electromagnetic field within a coil to transfer energy
to a workpiece. The table below shows values of the flux density in microTesla (µT).
These measurements can be used as a guide conforming to local regulations regarding
the maximum time exposure to magnetic fields. Different configurations may give
different values. It is impossible to provide values for all combinations as the variety
of bearing types in combination with the different yokes is large.
SAFETY FEATURES
Total 50Hz RMS field for magnetic measurement results. Max. magnetic flux in safe exposure area, according
to the German BG 11 Regulations is 423 µT.

SETTING UP THE WORKPIECE
`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.
` The weight of the work-piece should not exceed the maximum weight as shown in chapter WORKPIECE
DIMENSIONS. Exceeding these limits may result in catastrophic equipment failure and may also lead to
personal injury.
`Ensure there is no contact between the mains cable and the workpiece. Damage to the cable may result in
electrocution.
` Never support components with a metal cable and avoid metal cables hanging in the proximity of the magnetic
field. Extremely high currents can flow through the cable causing it to heat quickly, resulting in risk of burning.
The workpiece can be set up in two different ways and must never touch the housing. Small objects are to be heated in
a vertical position.
VERTICAL HORIZONTAL
`Choose largest possible yoke which fits 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.
`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.

To prevent the hardware from overheating, make sure
to reduce the maximum power output according to
the table.
` Always use the magnetic temperature probe (hereafter referred to as the ‘probe’) for heating in Temperature
Mode or Ramp Mode.
`Place the probe on the workpiece, close to the bore. Make sure that the surface used for the probe is
free of grease and/or oil.
`If the induction heater has two probes: place one close to the bore and the other on the outer ring.
` Our standard probes are suitable for operation up to a maximum temperature
of 240°C (464°F). The connection between magnet and probe will break above
the maximum temperature. If this occurs when operating in Temperature
Mode, the heater will turn itself off as the probe will fail to register any
increase in the temperature over a set period of time. Probes for higher
temperatures are optional.
`Connect the probe by inserting the plug into the socket at the front of the
heater, with the red dot facing upwards.
When using Ramp Mode or Temperature Mode with two sensors, the actual effective power will constantly
change during the heating cycle. This is done automatically. When using Time Mode or Temperature Mode with
one sensor, the standard effective power is 100%. Turning the power down is needed when:
`Applying smaller yokes, especially during continuous use.
POSITIONING THE MAGNETIC TEMPERATURE PROBE(S)
