• Weight-loaded safety valve "H": being adjusted at 50
kPa (0,5 bar) it starts allowing steam to exhaust as
the pressure in the jacket approaches this value. It is
equipped with a liftable knob enabling the control air
escape.
Note: check the effectiveness of the safety valve
when installing the equipment for the first time,
and then every six months.
• Working pressure switch, calibrated at 40 kPa (0,4
bar): it enables to keep the jacket pressure adjusted
in a range near this value.
• Indicator of water level in the jacket via two cocks
"F1" and "F2".
The water level in the jacket must be checked
every day.
• Safety thermostat: it trips to close the gas solenoid
valve when the bottom wall is overheated for lack of
water or for other causes.
After waiting until the appliance is cold and adding
decalcified water in the jacket, restart the equipment
operation unscrewing the protection cap "L"
available on the control board of the cooker and
pressing the red pushbutton.

8 - CLEANING AND MAINTENANCE

Before
starting
any
operation, disconnect always the power supply
before the appliance.
• When cleaning the appliance (outside and, where
necessary, inside), use only products with a
biodegradability exceeding 90% to reduce the
emission of pollutants in the environment.
• Wash the steel parts with soapy lukewarm water
every day, then rinse out with plenty of water and
dry carefully. Remove any scales with a nylon brush.
• Avoid any continuous or occasional contact with iron
material
absolutely
processes. Consequently ladles, spatulas, spoons,
etc. must be of stainless steel.
• For the same reason do not clean stainless steel
with wool, brushes or scrapers of common steel. If
necessary, wipe with stainless steel wool or with a
Scotch Brite™ cloth in the direction of glazing.
• Add salt only when water is boiling, and any
leftovers must be eliminated immediately after the
end of every cooking operation.
• Never use coarse salt because it could provoke
corrosion phenomena on the tank bottom as it melts
down very slowly. Therefore use fine salt (with grain
size lower than 3 mm); if this is not available,
dissolve the salt with hot water in a separate pot
previously.
• If the cooker is not used for long periods, wipe all the
steel surfaces strongly with a cloth soaked with
white mineral oil to cover them with a protective film;
moreover drain the water from the jacket and
ventilate the rooms periodically.
• When the cooker is not used, its lid must be kept
open.

• The equipment must undergo a total check
periodically (at least once in a year). The efficiency
of the safety devices and the lid balance must be
checked by a skilled engineer at least every six
months.
• It is better to drain the jacket completely once in a
year by opening drain valve "P".

9 - IMPORTANT ADVICES

• When washing the equipment, do not flush out
nor use water at high pressure because any
infiltration
in
compromise the good operation and the safety.
• Do
not
use
any
containing chlorine (bleach, hydrochloric acid,
etc.) to clean the steel.
• Do not use any corrosive substance (e.g.:
hydrochloric acid) to clean the floor under the
equipment.
• The ventilation capacity for combustion and the
electric system cannot absolutely be modified.
• This appliance is manufactured with recyclable
metals
(stainless
galvanized sheet, copper, etc...) for over 90% of
their weight, therefore these materials can be
recycled
in
normal
compliance with the regulations in force in every
country.
• When disposing of this equipment, first of all
remove the power cord. Then remove also the
lid to avoid that somebody can be kept closed
inside the tank.
