The instrument's analog storage enables the set temperature to be protected from short power cuts so that the appliance
can resume operations from the state in which it found itself at the moment in which the power supply failed.
If the time that elapses between the switch-off of a board in 'START' status and the next switch-on falls within the
protection period, when power is restored all the previously set data are shown.
If the power remains switched off for a period that is longer than the protection the display shows the message 'PF',
which alternates with the measured temperature value and the intermittent acoustic signal is activated. Press switch A for
at least 1 second to leave this alarm status and restore the previously set conditions.
If the device has faults, the display shows the relative fault message:
"EO" flashing on the display and an intermittent sound indicate one of the following faults:
- incorrect type of probe or probe or connections fault;
- temperature outside measurable range.
Check instrument-probe connection and correct operation of the latter (output is deactivated).
"E2" flashing on display and intermittent sound indicate the following fault:
- damage to stored configuration data.
Try to switch off the appliance and switch it on again (output is deactivated).
"EOC" flashing on display and intermittent sound indicate the following fault:
- compensation circuit of cold joint faulty (output is deactivated).
Call after-sales service.

CLEANING AND MAINTENANCE

3.1 ROUTINE MAINTENANCE

At the end of the working day, clean the appliance, both for reasons of hygiene and to prevent operating faults.
Do not clean the appliance with direct or high-pressure jets of water, is forbidden to use flammable materials, solvents,
and do not use metal pads, brushes or scrapers in normal steel. If necessary, use stainless steel pads, but do not rub
them against the grain of the metal of the appliance.
Use warm soapy water on steel surfaces and then rinse in plenty of water and dry with a soft cloth. Maintain the shine by
regular polishing with a normal liquid polish.
Do not wash the work top or floor with hydrochloric acid.
OIL-COLLECTING TANK
Check regularly that the oil level does not reach the brim of the oil collector and that the filter is free. Empty it regularly
and clean the filter. The pull-out handle on the top edge makes it easier to catch hold of the tank..
3.2 SPECIAL MAINTENANCE
At regular intervals (at least once a year or more often in cases of frequent use), service the appliance thoroughly.
This includes checking the gas circuit, checking parts for damage and if necessary lubricating the taps if they are difficult
to use. Contact a specialized and experienced technician. A maintenance contract should be taken out with a centre
approved by the company.
