correct data, see the plate attached to the panel and the
data shown in the section on the machine’s technical
specifications.
1.10. Inteded use
Roaster Centoventi was designed to work on a continuous
cycle of automatic processing, it has a tank capacity of
20/25Kg and has the ability to roast 50Kg of coffee or dried
fruit per hour. It uses an original and exclusive air cyclone
system (vertiflow® patent) which has a temperature
sensor at the heart of the product. It is particularly versatile
for the roasting of coffee, hazelnuts, almonds, pistachios
and any other appropriate product...The machine has a
number of programs which control the heating
temperature, the roasting time, the cooling time and the
final automatic discharge of the products. The programs
can be personalised to obtain the desired grade of
roasting time after time.
Warning
A use other than that specified is considered
improper. The machine is intended for professional
use only.
Attention
Do not place any small objects near the control
panel or the tank: they could fall and enter the tank,
which would contaminate the product.
1.11. Operating environment
To guarantee proper functioning the machine must be
protected from atmospheric agents. Its ambient
operational temperature should be between 15C° and
35C° with relative humidity not exceeding 70%.
The working environment must be clean, sufficiently
illuminated and away from an explosive environment.
The environmental characteristics of the installation site
are specified in section 4.
Attention
The machine’s fixed guards have a variety of
openings to allow the internal units to cool. When
the machine is running, make sure that these
openings are not covered by cloths or objects that
obstruct proper air flow.
1.12. Noise level
The phonometric tests carried out on this specific machine
model show an acoustic pressure lower than 70 dB(A).

1.15. Storage
Remove the remaining product left in the machine
following the instructions in the appropriate section.
Stop the machine using the main switch and
disconnect it from the electricity main. Move it to a
spacious place (it is necessary to work all around the
machine).
Clean the tank, the removable components (i.e. screw
pump, mixer, nozzle) and the pipes as described in the
appropriate section.
Attention
It is absolutely necessary to follow the
instructions in order to insure the safety of the
operators and to avoid damaging the machine’s
removable parts.
Use a brush to cover the movable components and the
mechanical moving parts with a thin layer of food grade
lubricant. This can later be removed with an alkaline
de-greaser (Sodium Hydroxide) if the machine needs
to be re-installed.
Carry out the same operation on the machine surfaces,
taking care of avoiding the heating elements located in
the inner part of themachine.
Gather the parts (use as reference the delivery packing
list) and put them in the original packaging. Place
packets of hygroscopic salt based on silica gel in the
packaging.
Store all the parts in a sheltered place away from
atmospheric agents and in temperatures from 0° C to
40° C. Cover the parts with nylon in order to prevent
the accumulation of dust.
1.16. Disposal
Disposal will occur at the end of the working life of the
machine, which under normal conditions of use and
maintenance will be over ten years.
In the case of disposal all the components of the
machine will have to be disposed of in adequate waste
yards according to the legislation in force.
Before disposal it will be necessary to separate the
plastic or rubber parts and the electrical and electronic
material.
Environment
Parts made solely of plastic, aluminium and steel
can be recycled in the appropriate collection
centres.
According to the RoHS regulations electronic
boards and electric material should be recycled
separately in authorised collection centres.
1.17. Warranty
The manufacturer offers a warranty on this machine
model for a period of 24 months from the purchase
date, as shown on the fiscal document issued at the
time the machine is delivered.
The warranty will be void if the machine is repaired by
a third non authorized party or if fixtures and
accessories not supplied by or recommended or
approved by the manufacturer are used.
The warranty will also be void upon removal or
alteration of the plate showing the serial number and
other data.
Within the warranty period the manufacturer will repair
or replace, free of charge, parts that are faulty due to
manufacturing.
In case the repair has to take place at the
manufacturer’s site, the machine will have to be sent to
the manufacturer in its original packaging.
Transportation expenses will be covered by the
manufacturer during the warranty period.
The warranty does not cover the cleaning of the
functioning parts.
Defects not clearly attributed to the material or the
manufacturing will be examined. If the claim should
turn out to be unjustified all repair expenses, changed
parts and transportation will be charged to the buyer.
The warranty does not cover damage caused by the
following:
accidental damage during transportation
damage due to lack of care or procedures carried
out incorrectly
damage due to improper use not conforming to the
warnings of the user and service manual
components subject to wear and tear; a detailed list
is available in the components section.
Structural damage, modifications, improper alterations
or repairs can affect the functioning of the safety
mechanisms, thus making the declaration of conformity
and warranty void. Alterations on the machine can be
carried out solely by technicians authorised by the
manufacturer.
