1. INTRODUCTION
SYNTHESIS E 5
1. INTRODUCTION
The electric conveyor ovens mod. SYNTHESIS have been designed
mainly for the automatic cooking of pizza and similar products. They are
conveyor ovens. Favourable peculiarity of these particular ovens is that it is
possible to make excellent baking, without controlling the same. For this
reason it is possible for un unqualified staff to use the oven.
SYNTHESIS belong to the family of conveyor ovens. Another important
innovation is that SYNTHESIS, thanks to their ventilation system, enable
an excellent and uniform baking. In fact, the flow of hot air surrounds the
product, removing the barrier of colder air that normally insulates it. This
ensures an uniform distribution of the heat in appropriate dosage, in order
to prevent the product from drying out excessively and giving it proper
fragrance.
Thank you for the preference given to us. We can confidently assure you
about your good choice, as our company has been committed to the
production of quality items since decades, without useless restriction in the

10 SYNTHESIS E
Install the appliance in a dry and easily accessible place both to facilitate
its use and to carry out cleaning and maintenance.
The appliance must be installed at least 20 cm from the walls of
the room or from other equipment so that the ventilation outlets
located on the sides of the oven are not obstructed.
Whilst in operation, cooking equipment produces vapor and cooking
smells that compromise the integrity of a healthy working environment.
A check must be made to ensure that the temperature and relative
humidity never exceed the maximum and minimum values indicted in the
specifications (see Enclosure A) even when the machine or other machines
in the room are functioning.
Exceeding these values especially the temperature or the maximum
relative humidity can easily and unexpectedly damage electrical equipment
creating hazardous situations.
4.3.Moving the unit
To offload and transport the unit, use
a pallet truck or a transpallet lifter with a
load capacity at least equal to that of
the unit. Raise the doors at the
entrance and exit of the oven to the
position of maximum aperture. Insert
the forks into the cooking chamber by
way of the tunnel entrance or exit
(Fig.1).
To avoid damage, place protective material between the forks
and the unit.
Make sure that the lifting equipment has a lifting capacity superior to
that of the weight of the load.
All responsibility for the lifting of loads rests with the person doing the
