5.3   Temp Mode

› 

If the main display shows “t”, press MODE to select TEMP MODE�The main display shows °C or °F in TEMP MODE�

›

  The selected temperature is shown on the main display� The default temperature for bearings is 110°C (230°F)� If a different 

temperature is desired, adjust the temperature on the main display�

›  

It may be desirable to heat bearings to temperatures above 110°C (230°F) for increased mounting time� Consult the bearing 
specifications to determine the maximum permitted temperature� Always ensure the bearing does not lock due to an 
excessive expansion of the inner ring compared to outer ring� See section 5�8�

›

   All Spherical Roller Bearings (SRBs) are subjected to a special heat treatment� These bearings can be operated at temperatures 

as high as 200°C (392°F)� Heating these bearings above 110°C (230°F) will not cause any damage as long as the bearing is 
still able to rotate� For other bearings, a temperature of 125°C (257°F) must not be exceeded unless otherwise specified�

› 

Press the 50% key to reduce the POWER to 50%� Use the guidelines in section 5�8 to determine the correct power setting�

›

  Press START/STOP to start the heater� The main display shows the current temperature of the workpiece�

›

  When the selected temperature has been reached, the heater demagnetises the workpiece, switches off, and generates an 

acoustic signal for 10 seconds or until START/STOP is pressed�

›

  Press START/STOP to stop the heater�

›

  Remove the workpiece with proper handling equipment�

›

  If the workpiece remains on the heater, the heater will start again when the temperature of the workpiece drops 10°C (18°F)� 

Press START/STOP to stop the heater and demagnetise the workpiece�

›

  The IHN800 is now ready to heat another workpiece with the same settings�

5.4   Time Mode

› 

Select TIME MODE� The main display shows “t” in TIME MODE�

› 

Set desired heating time by adjusting on the main display�

› 

Press 50% to reduce the POWER to 50%� Use the guidelines in  section 5�8 to determine the correct power setting�

› 

Press START/STOP to start the heater� The main display shows the time that remains�
