1.3 ADVISES
1.3.a Important maintenance
• Before carrying-out the cleaning and maintenance operations, disconnect the equipment from the mains
power supply.
Check and clean the jets frequently. The frequency of such operation should be determined according to
the amount of residuals and crusts or to the results of the washing operation not being satisfactory.
Never use corrosive products like sodium hypochlorite (chlorine water or similar) and chloride acid
(muriatic acid), acids, steel-wools, steel brushes, to clean the inner and outer surfaces of the machine.
• In order not to jeopardise the good operation of the equipment, in the presence of calcium or magnesium
salts in the water it is suggested to make a periodical scaling; this operation should be carried-out by
professionally qualified personnel.
• In order to avoid any risks of oxidation or chemical aggressions in general, it is necessary to keep all steel
surfaces well cleaned.
1.3.b Achievements
Any halos might be caused by an insufficient rinsing: in this case, check that the rinsing jets are clean and there
is a sufficient pressure in the water distribution network.
Any deficiency in the washing process is apparent when dirty residuals are visible.
In the case that dirty residuals are present, check that:
• the washing jets are clean
• the water temperature is 55°C
• there is a chlorine-active detergent in the right concentration and for industrial washing;
• the pump suction filter is clean
• the rack is suitable for the dishes to be washed
• the positions of the objects in the rack are correct.
1.3.c Extended machine stop
Should the machine be stopped for an extended period of time (some weeks), it is suggested to make the
machine run with no load and clean water, to prevent unpleasants smells and dirty from resting in the pump.
If necessary, repeat this operation several times until water is well clean after no-load washing.
If the stopping period is very long, it is suggested to oil the stainless steel surfaces by Vaseline oil and drain
the water from the boiler and the electric pump. It is always advisable to carry out sanitization and descaling
operations before and after the non-use period.
1.3.d Sanitizing
It is vital to thoroughly clean the machine at least once a week. It is advisable to use specifically a detergent
which disinfects, the use of which will substantially increase the following advantages:
• establishes a secure hygenic state by using active detergents and disinfectants.
• maintains the machine in perfect hygienic conditions even during periods of non-use
At the end of the operation, it is necessary to run the machine empty,so as to rinse it, for a few minutes.
1.3.e Disencrustation
In the presence of the use of hard water, lime deposits may formulate internally and on the dishes, which for
hygienic reasons and for good care of the machine must be removed by disencrustation.
The frequency of such procedure is according to the detergent manufacturers advice, those products which
generally contain a phosphoric acid base.
So as not to damage the machine, do not exceed doses and when the operation is complete, rinse thoroughly.
