0. WARNINGS

IMPORTANT

Read this instruction manual before switching the oven on.

FOR YOUR SAFETY

Do not use or store petrol, inflammable liquids, or gases near this equipment. Nothing should be baked
in this oven that contains alcohol or gives off inflammable gases during baking.

STARTING UP INSTRUCTIONS

This unit must be grounded for your protection in order to avoid the risk of electrical discharges. It
should be connected directly to the ground terminal of the control cabinet. The ground cable must not
be cut or disconnected from the oven.

CAUTION

During the baking process in order to avoid the possibility of burns produced by the steam, the door
shall be opened with care.

NOISE LEVEL

The acoustic power emitted by the oven is lower than 70 dB.

Keep this instruction manual in a safe and accessible place.

1. PREASSEMBLY INSTRUCTIONS

1.1 STORAGE AND TRANSPORT

The oven is sent packed on a wooden platform, covered with plastic film, that protects the machine
against humidity and rain.

The oven should be transported in a completely closed vehicle and it should never be left outdoor.

1.2 CONDITIONS FOR USE

• The oven has been manufactured to be installed indoor. It is not made to work outdoor. Any possible
contact with water has to be avoided.

• The oven should not be installed in places with excessive heat, steam and/or humidity production.

• The oven is prepared to work under the following external conditions: -10 <t> 40 ºC (14 <t> 104 ºF),

and 0 <h> 90 % of humidity

• The room in which the oven has to be installed must have an adequate ventilation. If there is a

fumes extractor, then a window with at least the section of the fumes extractor should be kept open.

• The position of the oven regarding the side and back wall of the installation premises should have a

minimum distance of 2" (50 mm) between the oven sides and the walls of the room.

VERY IMPORTANT

1.4 ELECTRICAL CONNECTION

This should be carried out by authorized professionals according to regulations in the country in
question. The appropriate circuit breaker for total amperage should be installed at the same time as the
premises’ electrical installation. The appliance should also have a plug fitted. UNPLUG THE OVEN

before accessing any of its electrical parts.

1.4.1 Three phase oven

Three phases plus ground are required for 230 V connection, three phases plus neutral and ground
for 400V connection.

EN 60204-1 requires that sections for three-phase cables plus ground or four-pole plus ground be as
follows:

1.4.3 Change of voltage of three-phase oven

The oven is supplied totally assembled and set for 400 V.

If the current on the premises is 230 V then prior to connection it will be necessary to alter the following
components accordingly:

1- Voltage change in the terminal plates of the motor and of the heating elements.

It will be necessary to disassemble the bridges connected for 400 V and reassemble then with the

230 V connection, as shown in the figure.

IMPORTANT: Securely tighten the nuts and locknuts of all terminals.

2- Bridge the terminals "T" and "N" (See scheme).

IMPORTANT: Before the oven is used, check that the air turbine is turning in the right direction, i.e.

from left to right as indicated by the arrow on the front separating plate of the baking
chamber. If the direction is wrong, then it will be necessary to change between two the
pin phases of the current intake on the oven cable

1.5 CHIMNEY

The steam outlet chimney should be installed by authorized professionals according to local
regulations.

Fundamental aspects:

• The chimney should preferable be insulated along its length and not in contact with combustible

materials (such as wooden beams or ceilings).

• Sections should not be horizontal, but should instead have a slope of at least 10º without bends or

elbows of radius less than twice the tube diameter.

• The chimney should incorporate a system for preventing backflow of condensates.

• It is recommended that the chimney used be insulated and of interior diameter 2 1/2".

• The steam outlet pipe from the oven should be coupled to this chimney.

1.5.1 Outlet chimney for oven steam.

To the draft outlet it is advisable to fit a hood and conduits, of the standard type normally fitted in
the case of butane water heaters, and release into chimney or directly to the exterior.

A- Optional

1.5.2 Joining two ovens steam outles.

When an oven is assembled on top of another oven, we recommend you to fit only one fumes outlet
for both, using a K5-K5 pipe coupling.

1 - Chimney.
2 - Outlet fumes pipe.
3 - Damp hood.
4 - Female T 90º 2 _ " x 2” x 2 _ ” G.
5 - Conical joint.
6 - Reduction nut 2 1/2" - 1".
7 - Reduction nut 1" - 3/4".
8 - Spigot 3/4" - 16 mm inside diameter pipe.

1.6 STEAM CONDENSER

When the premises are so situated that the steam outlet from the oven cannot be to the exterior, a
good solution is to fit a SALVA CV-K CONDENSER. Designed for such cases, this will condense oven
steam and facilitate its removal by drain or sink.

1.6.1 Joining two ovens steam outlets to a condenser.

When an oven is assembled on top of another, it is advisable to join both steam chimneys toghether,
so that a single chimney is required, using a K5-K5 pipe coupling, that can then be joined to a
fumes condenser.

1.7 WATER INSTALLATION

It is very important that feedwater to the oven be demineralized.

The place where the oven is to be installed must have a water intake on which a constant water
pressure of 1,5 kg/cm2 is assured during a steam injection by means of a pressure regulator device.

The connection between this connector and the oven will be by flexible hose-pipe of an inner
diameter of 10 mm (0.4 inc.)..

NOTE: For those cases in which water is calcareous, it is necessary to install a water softener between
the water supply and the oven intake. (Not supplied with the oven)

Fitting of the water softener decalcifier is shown in the following drawing.

A - Water intake from mains.
B - Water input to oven.
C - Drain-off from water softener.
1 - Water softener.
2 - Pressure regulator.
3 - 3/8" manual valve.
4 - Couple hose, 3/8".
5 - Coupling hose.

If a connection between point B (water softener outlet, Fig. ka0021c0.ei1) and point D (oven water
intake Fig. vistatra.dft, see point 2.1), is desired, this must be done with 3/8 “ diameter hose leaving at
both ends a 1/2 “ male pipe.

1.8 DRAIN (OPTIONAL)

It is necessary to construct a drain of diameter at least 1". This should preferably be made of metal and
should be temperature-resistant in any case. It will be coupled to the oven by a flexible hose of internal
diameter 18 mm, washing-machine type.

4. MAINTENANCE INSTRUCTIONS

IMPORTANT

Maintenance and reparation works should be made by the INDUSTRIAL SALVA, S.A. Official
Technical Service or by one of our distributors.

IMPORTANT: Before carrying out any repairing or servicing of the electrical oven parts, the
magnetothermical protection devices located behind the control panel must be switched off. As far
as possible, work with the current disconnected from the power supply..

Daily maintenance

The glass panes of the door are to be cleaned carefully and with soft, nonabrasive detergents, to avoid
damaging the silkscreen print. To access the inside of the panes, the mould on the opposite side of the
hinges must be slid upwards in order to let the pane down. Carry out the same procedure inversely to put
the pane back, making sure the rubber seal is well placed.

Monthly maintenance

The internal parts of the oven should be cleaned: floor, roof, and sliders (to clean the internal parts of
the oven it is necessary to withdraw the sliders from the chamber. (see point 2.3)..

The internal parts of the oven should be cleaned: floor, roof, and sliders (to clean the internal parts of
the oven it is necessary to withdraw the sliders from the chamber. (see point 2.3).

NOTE: If this oven is been used continuously without stop, the internal parts of the oven has to be
cleaned more than once a month.

6 month period maintenance (should be made by the Official Technical Service of INDUSTRIAL
SALVA, S.A.)

The motor cavity and sorroding areas must be cleaned.

NOTE: Lach of clean may causean early failure on the electrical motor.

The electrical parts of the oven should be cleaned. Special care should be taken in not wetting the
oven controls, since major faults could occur in the electrical system.

NOTE: Dust and flour could cause malfunctions of the electrical components of the electrical

control box.
