The foundation
Our company was founded in 1963 by the Lorenzo, Luigi and
Paolo Cuppone brothers. It immediately specialized in the
production of ovens and equipment to prepare and cook pizza.
The constant research and experimentation of new equipment
that are even now the strength of our company, have led us
to design and patent the machinery and ovens that have
revolutionized the way pizza is made.

2CHECKS BEFORE PURCHASING
Before purchasing the steamer and installing it, check the
following conditions, necessary for the correct installation,
operation and maintenance of the steamer.
A Transport (Owner’s inspection)
√Make sure that, on the day when you receive the
steamer or it is installed:
• lifting equipment is available that can handle the
appliance safely (check weight and dimensions in the
following pages), together with staff qualified to carry
out this operation;
• personal protection equipment is available (e.g. safety
shoes, gloves, etc.)
B Oven it can be tted to
The steamer can only be connected to the following
versions of the Leonardo oven:
• LN2T/1TS-B6-US - LN2T/1TSH-B6-US
• LN3T/1TS-B6-US - LN3T/1TSH-B6-US
• LN650/1TS-B6-US
C Electrical connection
• Fig. 1
The steamer does not have its own power supply
(therefore it is not necessary to provide additional
sockets) but connects directly to the Leonardo oven on
which it is fitted with the cable already provided.

FINAL SITUATION AFTER ASSEMBLY
DWaterconnection (qualiedplumber’sinspection)
Fig. 2
The steamer requires a permanent connection to the water
supply by means of a 1/4 ”connector on the back of the
same. The steamer is equipped with a ow reducer and a
Y lter with a 300 micron filter mesh on the water loading
circuit (both are located inside the steamer and therefore are
not visible from the outside).
To avoid corrosion and limescale phenomena, the
incoming water must have the following chemical/physical
characteristics:
• have a maximum temperature of 30°C;
• be drinkable;
• have a pressure value between 150 and 600 kPa (200 kPa
recommended). If the inlet water pressure is lower than
the specified minimum value (150 kPa), a pump must be
installed (minimum flow rate: 300 l/h);
• have 1000 μS/cm maximum water conductivity;
• Free chlorine ≤ 0.1 ppm
• Chloramines ≤ 0.1 ppm (mg / L)
• TDS ≤ 125 ppm
• Silica ≤ 12 ppm
• pH 7 ÷ 8.5
• Total hardness (TH) ≤ 6 °dH
• Chlorides ≤ 25 ppm
• Alkalinity ≤ 150 mg/L as CaCO3
If the water values differ from those listed above, it is
necessary to adequately treat the incoming water to bring
the values within the limits indicated for each circuit.
It is advisable to install an shut-o cock (not supplied)
between the water mains and the steamer.
For the connection to the water mains, a new hose (not
supplied) must be used; the hoses already used must not
be reused.

What this equipment is for
The steamer is an appliance capable of emitting steam inside
the Leonardo oven to which it is connected.
The steamer was designed exclusively for use with water;
different types of liquids can cause irreparable damage, not
recognized under warranty, thus reducing the life span.
How to use the steamer
Fig. 4
• AActivate the steamer by pressing the power button on the
control panel of the Leonardo oven to which it is connected,
the steamer does not have its own controls.
• BThe steamer starts to preheat; the first time it is switched
on, preheating will take approximately 10 minutes. In this
phase, the "STEAMER" icon is RED to indicate that the steamer
cannot be used yet.
• When the steamer reaches the temperature of use, the
"STEAMER" icon turns GREEN and it will be possible to
insert steam into the cooking chamber either manually
or automatically, using the Touch control panel of the
Leonardo oven to which it is connected. For the use of the
Touch panel, see the dedicated chapter "Using the steamer (if
provided)" in the Leonardo oven manual.
• After injecting steam into the chamber, it takes a while for
the steamer to return to temperature; during this interval
the "STEAMER" icon turns RED, this means that it is heating
the water again and therefore CANNOT be used until the icon
turns GREEN again. Recovery time depends on the quantity
of steam injected into the chamber, the maximum time is
about 15 minutes.
If the icon is red, the steamer is warming up
and cannot be used yet.
If the icon is green the steamer can be used.
B
The temperature of the steamer is controlled by a temperature probe. If for any reason the probe does not work, the
steamer is equipped with a manual reset safety thermostat on the back which will intervene by removing power from the
elements. IT IS ABSOLUTELY FORBIDDEN TO BLOCK THE SAFETY THERMOSTAT RESET BUTTON WITH ANY MEANS. If for any
reason the capillary of the thermostat breaks and oil leaks out, the safety thermostat will intervene and can no longer be reset.

Warnings
Before any cleaning, it is necessary to switch o the
power to the Leonardo oven it is connected to (acting
on the system switch) and wear suitable personal
protection equipment (e.g. gloves, etc.). The user must carry
out only routine maintenance, for extraordinary maintenance,
contact the Dealer requesting service from an authorised
technician.The Manufacturer warranty does not cover damages
due to negligent or incorrect maintenance or cleaning (e.g. use
of unsuitable detergents).
Any cleaning must be carried out with the steamer
andunderlying ovencompletelycoldandwearing
adequate personal protection devices (e.g.
gloves, etc.).
When cleaning any part or accessory do NOT use:
• abrasive or powder detergents;
• aggressive or corrosive detergents (e.g. hydrochloric
or sulphuric acid, caustic soda, etc,).
• abrasive or sharp tools (e.g. abrasive sponges, scrapers, steel
brushes, etc.);
• steamed or pressurised water jets.
It is best to have an authorized service centre perform
maintenance and inspection on the appliance at least
once a year to ensure top working and safety conditions.
Cleaning the steamer
Cleaning the external steel parts
Fig. 5
Use a cloth dampened with hot soapy water and end with

Problem Solution
The steamer does not
deliver steam
• Check that the steamer is correctly connected to the Leonardo oven (plug correctly inserted Fig. 7).
• Check that the electricity has not been interrupted and that the system's mains switch is turned ON.
• Check that the steamer is correctly connected to the water supply by means of a hose and that the
water shut-off cock is not turned off.
• The steamer, both in the preheating phase and after delivering steam, needs some time to return
to temperature; during this interval the "STEAMER" icon turns RED, this means that it is heating the
water again and therefore CANNOT be used until the icon returns to GREEN. Recovery time depends
on the quantity of steam injected into the chamber, the maximum time is about 15 minutes. If the
icon is fixed red, it is necessary to contact the Reseller.
