HEATING INDUCTOR REPLACEMENT PROCEDURE

1. Leave the device on a fireproof surface for a time needed for the induction coil to cool down.
2. Disconnect the device from the grid power supply to prevent unwanted starting while replacing
the induction coil.
3. Loosen the screws securing the coil and then slide the coil off the cooled terminal.
4. Insert the desired induction coil and tighten the fastening screws.
5. Connect the device to the grid power supply and wait for the fan to start; the device is ready for
heating after that.

WORKING CYCLE

The INDUCTION HEATER is designed so that it can heat for up to 20 minutes when started cold under
normal conditions with an ambient temperature of 25°C. However, various influences may occur in use
that result in a shorter heating time.
These influences include:
Reduced air supply to the device, reducing its cooling.
Reverse heat transfer from the working object to the heating inductor.
Dust clogging the device.
Heating inductor condition.
That is why the device working cycle information is approximate only and always depends on the
working conditions. The device has temperature measurement for critical components and does not
permit the user to engage the output circuits for so long that device overheating might pose a risk arising
from device overheating.
The recommended working cycle is 10 minutes of heating followed by a minute of cooling.
CAUTION: The coil and the heated object may reach high temperatures and cause burns and/or
a fire.

PROTECTIONS AND LIST OF ERROR MESSAGES

Protection from short circuit and output
overcurrent
Device overheating protection
Accessory overheating protection
Protection from operation under non-standard
grid conditions
Error messages comprise simultaneous acoustic and light signals. The error message number always
equals the number of short (0.5 s) light and acoustic signals following the long (2 s) light and acoustic
signal, repeated 3 times. The error message repetition can be cancelled after the first indication by
pressing the button. Pressing the button one more time places the device in the heating mode.
