6.3. CLEANING
• Before any cleaning operation, verify that the equipment is disconnected from the electric socket.
• Carry out the cleaning operations only with empty and completely cooled oven.
For the cleaning of the machine:
• Do not use detergents and instruments that can scratch or damage the surfaces;
• Do not use abrasive sponges or aggressive or corrosive detergent products;
• Avoid foam products, e.g. self-cleaning for oven;
• Do not clean the equipment with water jets or pressure steam jets, as they could provoke damages to the electric installation;
use commercial products homologated for the aim;
• Observe the modalities of use and adopt individual protection devices foreseen for the use of these products.
6.4. CHECKLIST: ORDINARY MAINTENANCE CARRIED OUT BY THE OPERATOR
For any type of operation or for the replacement of the parts, activate the maintenance service.
Table of the ordinary maintenance (6.4.):

• of the electric connections
ELECTRIC OVEN
The work place and all the external parts of the electric equipment must be clean; besides, even-
tual parts placed on the electric equipment must be removed, because they could prevent the cor-
rect operation and compromise the safety conditions originally present in the electric equipment.
The lamp of illumination of the baking chamber, the tempered glass of the baking chamber and
the oven door must be intact without fissures.
Carry out a visual inspection and a functional test of the control devices, the foreseen interlocks
and the stop functions in order to ensure their correct operation and stop of
the movable elements.
Carry out, with the suitable tools, a tightness control of the terminals, screws, nuts, bolts and
connections in general.
Verify the whole electric equipment for requirements of continuity of service and functioning.
You must control that all the elements subject to wear, e.g. cables, terminal boxes, actuators
actuated by the user, are intact and functioning.
With suitable instruments, measure the resistance towards the grounding of the equipoten-
tial and protection installation and of any connection, so that the values are within the limits
of acceptability of the law in force in the country where the machine is installed. In connec-
tion with the above instructions/indications, the corresponding grounding system must
completely conforming to the applicable requirements for coordination with active associa-
ted devices, in accordance with IEC364-5-54 / HD382-5-54 / CEI 64-8 (5-54) (latest editions).
With suitable instruments, measure the absorption on each conductor of users feeding;
Values that are not in a range of 10% indicate breakages; in this case, activate the maintenance
service in order to verify all the other characteristics of the users and the motor, as this could
fail soon. Verify the absence of possible loosening. If present, restore the connections in a stable
and long-lasting way by tightening the connections with suitable torque moment reported di-
rectly on the electric components.
The control must besides regard:
• the integrity of the junction boxes, casings, pushbuttons and protective sheaths of the electric
cables;
• the functionality of all the control and power actuators.
