ATTENTION
Regularly check and clean the spray arms, removing
them from the columns and removing any debris and
deposits. The frequency of this operation depends
on the amount of residue or on unsatisfactory wash-
ing results. To wash the outside of the machine,
do not use corrosive products such as sodium
hypochlorite (bleach) or hydrochloric acid (muriatic
acid) with steel sponges or brushes.
2.4. DESCALING
In the presence of hard water, limestone deposits are formed
inside the machine and on the dishes which, for hygienic and
operational purposes, must be removed by descaling.
The operating procedures and their frequency are usually
recommended by the supplier of the descaler who has ap-
propriate products.
To avoid damaging the machine, do not exaggerate with the
dosages, and strictly abide by the instructions of the descaler
manufacturer. When the operations are completed, rinse with
plenty of water.
2.5. PUTTING TEMPORARILy
In case of a prolonged stop of a few weeks, before clos-
ing the machine, it is recommended to fill the tank with
clean water and to perform a few empty cycles. Then
drain the water so that bad smells are not produced
and the pump does not remain dirty.
If necessary, repeat this operation several times until
the water is clean after the empty wash cycle.
If the downtime is too long, it is recommended to oil the
stainless steel surfaces with vaseline and to drain the
water from the boiler and the electric pump.
2.6. DEMOLITION and
20
When you intend to scrap the machine, drain the water
16 from the tank and the boiler, as indicated in the previous
points, and disconnect the machine from the water and
electric mains. Then dismantle the components follow-
ing that prescribed in the relevant standards in force
in compliance with the national and local ecological-
environmental regulations, taking care to separate the
parts as follows:
- metal parts: body, surfaces, panels, filters;
- electric parts: motors, contactors, microswitches,
- plastic parts: fittings, dish racks;
- rubber parts: hoses, sleeves.
2.7 SCHEDULED

ing to the scheduled maintenance at least every 6
