ORDINARY MAINTENANCE
GENERAL INFORMATION
Check the cleanliness of the heating tool's contact surfaces. If
necessary, clean it with a soft cloth.
Check the cleanliness of the infrared lamp glass and, if
necessary, clean it with isopropyl alcohol and a soft cloth.
Keep the machine clean. Do not use water jets to clean the
machine as they could penetrate inside. Also avoid using
strong solvents, thinners or gasoline that could damage the
paint or the machine's plastic parts.
Clean the control unit's screen using a dry soft cloth; do not
use water, solvents, alcohol or abrasive cloths. Limit the
exposure of the control panel to direct sunlight.
ELECTRICAL CIRCUIT
You should frequently check the condition of the power cord,
the plug and the heating tool connecting cables. Replace the
power cord if you notice any cracks, cuts, scrapes, etc.
Make sure the machine is connected to the protective
conductor and that the ground wire, both inside the power cord
and the heating tool connecting cable, is not interrupted.
Periodically check the ground efficiency of the system.
COOLING CIRCUIT
Keep the water level in the chiller
within the “normal” water
level.
Clean the chiller heat exchanger, Item CHH5480, using
compressed air, on a regular basis.
Check that slag/waste of any kind does not deposit inside the
tank and hoses, otherwise remove and wash properly.
WARNING: do not keep the machine in places where the
coolant could FREEZE.
If you have to store the machine in a place where the aforesaid
risk subsists, be sure to use an appropriate amount of antifreeze
otherwise empty the cooling circuit completely.
EXTRAORDINARY MAINTENANCE
Only specialized technicians are allowed to perform
interventions inside the machine.
The machine is equipped with a thermostatic safety device. If it
overheats, the following message is displayed:
TEMP
Do not power off the machine but let it cool down. This message
clears automatically once the machine has cooled.
The control unit's internal memory is powered by a lithium battery
type CR2032. Replace the battery in case of a memory
malfunction. Perform the replacement after unplugging the
power cord and be sure to use only a similar battery.
