1) Place the machine in its place of intended
use in compliance with the following instructions:
- Check that there is enough space (minimum 19”) from any walls or obstacles
which may prevent proper air flow (fig.2).
Fig.2
-
Check that maintenance can be performed
with a certain freedom of movement.
- Avoid placing the oven in places with poor
air circulation, in places exposed to sunlight,
where there are high temperatures, near
heat sources or in windy locations (fig.3).
- Ambient air temperature must not exceed
89°F. Above that temperature, proper operation of the oven cannot be ensured.
Fig.3
-
Always install the oven under a properly operating aspiration hood for the extraction of
vapors.
2) Remove the film which covers some parts
of the oven before starting to use it.
3) Clean all substances, including glue residue.
Do not use abrasive substances.
4) Position the machine so that it is perfectly
level and set the height by means of the
leveling feet (fig. 4).

ELECTRICAL CONNECTIONS
The oven is setup for operation at the voltage
set forth on the technical data plate.
All ovens are provided with a power cord.
Fig.5
The flexible cable for connection to the electrical mains must not have characteristics which
are less than those of a type with rubber insulation mod. H07RN F and it must have a section which corresponds with that set forth in
the section “Technical Data” of the oven. The
cable must also be anchored to the frame with
the cable clamp, the screw of which can be
reached through a hole in the frame. It must
in any case be positioned in such a way that at
no point does it reach a temperature which is
122°F greater than the ambient temperature.
It must be type SJTO plug 20A 250V P section
3xAWG12.
The connection to the electrical line must be
made by placing an automatic switch of sufficient capacity (see “Technical data” of the
oven) and with an opening distance between
contacts of at least 3 mm.
Also, during operation of the oven, the power
supply must not vary from the nominal voltage
value by ±10%.
The oven MUST be earthed by means of the
terminal which carries the earth symbol
on the connection board.
It must also be inserted in an equipotential
system (the efficiency of which must be
checked in accordance with current standards)
using the terminal with the equipotential symbol (fig. 6). It is located near the electrical cable
entry on the panel of the oven bottom.
The manufacturer will not be held liable if
this accident prevention standard is not
adhered to.

It is checked by the fuses positioned on a terminal block at the line entry.
Pr o T e c T i o n o f T h e c h a m b e r f a n
A remote switch stops the fan motor in the
event of a malfunction or overload. It is located
behind the oven and must be reset manually.
When it cuts in, it stops the motor and shuts
off the heating elements.
ov e n c h a m b e r S a f e T y T h e r m o S T a T
The safety thermostat disconnects the heating
elements if the temperature in the oven chamber is too high (644°F).
It must be reset manually. If it activates, technical service must be notified.
All components are protected by the following
type of fuse: CLASS CC,G 600V 20A.
REPLACEMENT OF SPARE PARTS
Replacement of spare parts must be performed exclusively by qualified and AUTHORIZED personnel.
Turn the main switch OFF and unplug
the convection oven before carrying out any
spare parts replacement.

GENERAL SAFETY STANDARDS
• This manual is
part of the documentation provided
with the oven and
contains all re-
quired information
for proper use and
maintenance of the convection oven.
• Carefully read the user’s instructions
contained in this manual before turning the oven on. Special attention must
be given to the standards concerning the
automatic safety and control devices.
• The user must carefully read the instructions in it and keep it where it is accessible
to all authorized users;
• The ovens is of a professional type and
must be used only by qualified personnel, which is the cooking of foods in
food service facilities.
•
Always turn off the main electrical switch after
using the oven, especially during maintenance
and repair or in the event of long periods of
disuse.
• It is advisable to have the oven checked on
a yearly basis by an authorized technical
service center.
• The owner of the oven must periodically
train their staff on the use of the machines
and provide them with safety instructions.
• During cooking, the external parts of the
oven (e.g. door glass) may get hot. Becareful when touching them.
ge n e r a l i n S T r u c T i o n S f o r u S e
• The oven may be used to bake creams,
cookies, cakes, sauces and pizza, for au
gratin cooking and for defrosting frozen food
convection ovens.
• Avoid adding salt to foods in the cooking
chamber.
•
Try to distribute foods evenly in the pans,
avoiding accumulations.
Fig.11
• Between one level and the next there must
be a space of at least 1 1/2”. Hot air must
be able to circulate both above and below
the food in order for it.
• Do not use pans with sides that are higher
than necessary. The sides create a barrier to
air circulation.
• When using the oven for the rst time, it
is advisable to run it empty at maximum
temperature for about an hour.
This will eliminate any unpleasant odors
from protective lubricants used in the factory.
• Leave room between dishes on the same
level.
• Preheat the oven. It is always better to place
the food in a pre-heated oven.
• During cooking, racks and pans reach very
high temperatures. Use caution to prevent
burns.

ROUTINE MAINTENANCE
Before performing maintenance, unplug
the oven.
During cleaning, use protective gloves, mask
and garments as required by standards.
At the end of each workday clean the inside of the oven with appropriate convection
ovens following the suggestions of your supplier. Do not use corrosive or acidic convection
ovens, or convection ovens which are not suitable for this type of cleaning.
To make cleaning easier, remove the lateral diffusers by lifting them slightly so they are free of
the holding pegs.
Clean the stainless steel parts daily with lukewarm soapy water, and rinse thoroughly. Then
dry.
Absolutely do not clean the stainless steel with
steel wool or common steel brushes, since they
may leave ferrous particles which may oxidize,
thus causing rust spots.
Stainless steel wool can be used in the direction of the satin finish.
If the oven is not used for long periods, use a
cotton ball to lay a coat of petroleum jelly on all
surfaces; also regularly ventilate the rooms.
ov e n c h a m b e r c l e a n i n g
•
Remove any food and/or fat residues from
the oven chamber after each cooking cycle.
• The combination of fat, heat and forced circulation dirties the oven. Only by cleaning
the oven daily is it possible to avoid difficult
cleaning operations.
• To clean the oven, use a suitable de-greasing convection oven (non-foaming) as suggested by your detergent retailer. A spray
is preferable to reach behind the protection shield. Do not use abrasive or corrosive substances, scrapers or steel wool (fig.
12).
Fig.12
Adhere to safety instructions included with
cleaning convection ovens for the protection
of skin and eyes. When cleaning, proceed as
follows:
a) Heat the oven chamber to approx.158-
176°F and clean it using the de-greasing
detergent in the recommended quantities.
b) Close the oven and heat it.
c) Let the cleansing convection oven act for
20-30 minutes and then turn the oven off.
d) Slowly open the oven with care to avoid
eye and skin damage.

move the rack supports attached to the side
and shield, remove the shield by loosening
the fastening screws. Wash separately (they
can also be placed in the dishwasher).
f) Clean and rinse the oven and fan with water.
g)
Re-install the shield and the rack supports.
h)
Dry the oven by turning the CONVECTION
cycle on.
To make cleaning the oven chamber easier, it
is possible to remove the door completely in a
few simple steps as shown in figure 13. Follow
the sequence in reverse order to re-install the
door.
cl e a n i n g d o o r g l a S S
To reach the inside glass of the oven door, use
the lower latch “A”, open outer glass “B” raising it from the bottom upwards. This will make
it possible to get inside the glass for normal
cleaning. Upon completion, close the external
glass by pushing it slowly downwards until the
click is heard of insertion in component
“A”.

cl e a n i n g T h e f a n
Periodically check the condition of the fan.
Make sure that there is not too much grease
on the blades since it may slow motor rotation
(which in turn may lead to overheating) and
uneven heat distribution (resulting in uneven
cooking).
