6.2 COOLANT REFILLING
Check and refill the coolant before each device starting. Use the original coolant only! DO NOT USE WATER!
The device has integrated coolant level inspection. In case the coolant runs out, the device stops heating and
displays the error message “E##”. In that case, refill the coolant in the tank as described above.
The DHI-44E LKW induction heater device comes with a basic focusing heating inductor. The other accessories
are listed in Chapter Spare and consumption parts.
Correct and safe functioning of the device requires the use of only original heating inductors, extenders,
adaptors and other accessories in accordance with their respective instructions for use.
The lifetime of each type of heating inductor and accessory is shown in its instructions for use along with
inspection and maintenance frequencies.
7.1 HEATING INDUCTOR EXTENDER REPLACEMENT PROCEDURE
1. Turn off the device using the switch at the back of the device.
2. Make sure the coolant tank is safely closed.
3. Grasp the grip so that it is in a vertical position with the extender facing upwards, at leat 20 cm
above the power supply unit. Maintain this position through the entire replacement procedure.
4. Unscrew the heating inductor extender by rotating it counterclockwise until it is released.
5. Make sure the threads and contact surfaces of both the grip and the extender are clean and free of
signs of corrosion.
6. Mount the new complete extender by freely rotating it clockwise until the outer contact surface of
the extender makes permanent contact.
7. Turn on the device and, after an initial venting of the cooling circuit, check the coolant level and add
coolant if necessary.
8. Make a visual check of the tightness of the extender-grip connection and any other connections of
the new extender. If there is a coolant leak, safe use of the device is no longer possible.
9. Check the conductivity of the connection by briefly activating the device without any heating
inductor load.
-
If the device display shows the output power, everything is alright.
If it shows „A.Fr“, the contact between the contact surfaces is incorrect. In that case, safe use of the
device is no longer possible
