4.2.4 Switching off the appliance
To switch off the pasta cooker turn the thermostat to position 0 (shown in figure 2). At
this point the line indicator light will switch off.
4.2.5 Safety thermostat
The appliance is equippedwith a safety thermostat. The safety thermostat trips if the tem-
perature of the heating elements increases excessively (fire protection function). This is a
safety feature in the event of malfunctions, faulty components, or improper use (no water
in the tank, dirty heating elements, etc.).
If the safety thermostat trips, disconnect power to the appliance and proceed as follows:
1. Wait for about 10 minutes for the water temperature to fall below 90°C.
2. Reset the safety thermostat as follows:
• Open the doors.
• Unscrew the nut under the control panel (shown by the arrows in figure 4);

General
Main causes for deterioration or corrosion of stainless steel:
• using abrasive or aggressive detergents, especially products containing chlorine
such as hydrochloric acid or sodium hypochlorite (bleach). For this reason, before
using a commercial detergent make sure it will not corrode stainless steel;
• accumulation of ferrous deposits(such asthose created by rust dissolved in the wa-
ter in the pipelines, especially after the appliance has remained idle for prolonged
periods); accumulation of ferrous deposits must be avoided as far as possible. Do
not use abrasive metal pads to remove stubborn food stains. Instead, use scourers
or spatulas made of stainless steel or softer, non-ferrous materials;
• accumulation of acidic substances such as vinegar, lemon juice, sauces, salt, etc.
Avoid prolonged contact of substances of this type with the stainless steel surfaces
of the appliance. Particular damage is caused by allowing saline solutions to evap-
orate on the appliance surfaces resulting in the formation of salt deposits.

Routine cleaning
Cleaning the appliance thoroughly on a daily basis is the best way to keep it in perfect
working condition and increase its working life. Clean the appliance with a damp cloth
and soapy water or detergent. Avoid acid or abrasive cleaners as discussed above. Do not
use aggressive detergents, even for washing the floor around the appliance, since these
products give off corrosive vapour that can deposit on stainless steel surfaces and damage
them. If the appliance is very dirty, clean it using a synthetic scourer (e.g. Scotch-
BriteTM). Rinse the appliance with clean water and wipe it dry with a clean cloth. Do not
use wire wool pads (risk of rust deposits and stains). For the same reason, do not bring
ferrous objects into contact with the appliance.
In order to prevent the formation of spots of corrosion ensure that all salt residues on the
sides and bottom of the tank are completely removed.
Never use direct water jets to clean the appliance: risk of water infiltration resulting in
malfunctions and damage.
Stains and scratches on the stainless steel
Scratches and stains can be removed using stainless steel wool pads or synthetic scourers;
always rub in the same direction as the satin finish.
Rust
If you need to remove rust stains seek advice from industrial cleaner manufacturers to
choose a suitable product. Industrial descaling products can also be used for this purpose.
After using the cleaning product and rinsing the appliance with clean water, an alkaline
detergent may be required to neutralize any acid compounds remaining on the surface.
Cleaning the pasta cooker
Periodically remove any accumulated limescale deposits using a specific scale remover
product as indicated below:
Do not breathe the vapours generated during this operation. Wear a facemask and rubber
gloves.
4.3.2 Periods of disuse
If the appliance is to remain idle for a prolonged period, after cleaning and drying the sur-
faces should be protected by applying a film of a suitable product (e.g. vaseline oil spray
or similar products).
Disconnect the electrical supply by setting the external safety breaker switch to OFF.

4.3.3 Routine maintenance
Service and maintenance procedures must be performed exclusively by qualified person-
nel.
The following maintenance operation should be performed at least once a year:
• checking proper operation of control and safety devices;
We strongly recommend entering into a technical assistance agreement providing for at
least one service per year.
4.3.4 Supplementary cleaning
Cooking pasta gives rise to the production of starch (of similar properties to egg white)
that tends to bake on to the heating elements. Clean regularly, 3-6 times a day, according
to the frequency with which the appliance isused. Turnthe thermostat toposition 0. Emp-
ty the tank following the instructions, open the drain valve and carefully wipe the heating
elements and the tank bottom to remove residual starch. Close the drain valve and fill the
tank up to the maximum level. Turn the thermostat knob to the required cooking temper-
ature.
