1. GENERAL INFORMATION
1.1. INTRODUCTION
The CR6 is a dispenser intended for the production of paint
for bodywork and CarRefinishing sectors, able to produce
both small quantities (e.g. 50ml) for touch-ups or colour
tests, and the quantities required to paint a complete car
(max. 1 litre per package).
The machine can be configured with a variable number of
circuits and canisters having different capacity, as
described in more detail below.
Each circuit can dispense a different product (products for
bodyworks).
Thanks to the accuracy and high resolution of the cutting-
edge dispensing systems designed and patented by Alfa,
the machine can reproduce any colour with exceptional
precision and absolute repeatability.
1.1.1. MODELS AND VERSIONS
This dispenser is available in three different configurations:
−CR6 (three modules, for a total of six product
dispensing heads and max. 96 total circuits);
−CR4 (two modules, for a total of four product
dispensing heads and max. 64 total circuits);
−CR2 (one module, for a total of two product dispensing
heads and max. 32 total circuits);
Each dispensing head consists of a rotary turning table
where up to 16 independent canisters can be housed.
Each dispensing head is equipped with one single
dispensing station.

GENERAL INFORMATION
EN
1.3.2. COLORANT TURNING TABLE
Each dispensing head can house up to 16 product groups.
Circuits are placed on a turning table, which allows
dispensing from the various circuits sequentially.
Each product group can be equipped with one 1.5, 2.5 or 3
l canister and is provided with its own dispensing unit.
There is only one actuator allowing dispensing and is
exclusively coupled with the group opposite to dispensing
(in front of the operator). Therefore there is only one
dispensing station for each dispensing head, which is the
same where circuit recirculation can be executed.
1.3.3. ACCESSING THE GROUPS
The canisters of the groups housed in the upper part of the
machine can be accessed by opening the relevant upper
cover (1).
To open the cover, it is necessary to unlock the latch using
the key supplied.
The same key is required to unlock the lower carriages and
open them.
The groups in the lower part of the machine, instead, can
be accessed by extracting the relevant carriage (2).
The carriages are held in place by a locking system that
uses guides and a magnet.
When closing carriage and doors, pay attention to possible
risks of crushing.
Extract one carriage at a time: close the open carriage
before extracting the adjacent carriage.
By convention, numbering of the dispensing heads (1-6) is
that shown in the figure.

1.3.4. LOADING AND UNLOADING ROLLER CONVEYORS
On the left side of the machine there are can input (1) and
output (2) roller conveyors, as well as the output tunnel (3).
Cans can be transported in the machine only by using the
proper shuttles. The shuttle has to be chosen according to
the volume of the can you want to use and is defined
during machine configuration.
Manually load the shuttle containing the can on the loading
roller conveyor, then send the dispensing start command
on Alfa40 software (see chap.4 –“HOW TO PRODUCE A
COLOUR”).
The machine will load the shuttle through the motorised
roller conveyor and will perform a consistency check
between the selected volume and the volume of the can
actually loaded.
At the end of the process, the can will be positioned on the
output roller conveyor, where it can be manually removed.
1.3.5. AUXILIARY FUNCTIONS
In addition to the colorant turning table, each dispensing
head contains a cleaning station (1), a roller conveyor for
shuttle movement (2) and an electrical control panel (3)
that provides some service functions, as described in more
detail below.
The cleaning station is used to clean the dispensing nozzle
of each group from possible colorant residues, preventing
nozzle drying and clogging.
For each dispensing head, the following connections are
available:
4. IEC320 type C14 socket for the connection of a scale
(max. 100W*);
5. USB-A port for scale connection, through USB-RS232
converter (present only on dispensing head 1);
6. Main switch for dispensing head switching off and
IEC320 socket disconnection;
WARNING: dispensing head switch 1 switches off the
supervisor as well.

1.6. RESIDUAL RISKS AND DANGEROUS AREAS
USER AND MAINTENANCE OPERATOR
The potentially dangerous areas associated with mechanical moving parts:
−Colorant turning table movement: the support base
rotation during dispensing or refill operations does not
present any risk that is not obvious; however, it is
advisable to be careful and not to approach the parts
with hands, arms, hair or clothes during operation.
−Circuit canisters: risk of squeezing arms, hands or
fingers due to the movement of stirring blade in case of
failure or malfunction of door opening sensors. Stirring
start is timed by the software and is sudden (excluding
when the machine is in diagnostics or refill mode). Do
not insert your hands into the canisters. Always shut
off the machine prior to performing any necessary
interventions.
−Lower carriage extraction: be careful when refitting the
carriage. Possible risk of squeezing hands and fingers
between the fixed and the mobile parts (figures on the
side)
TECHNICIAN: The authorised technician can remove the machine fixed protections and access the internal parts
containing live electrical components.
−Electrical panel area: risk of electric shock.
Any intervention that requires the operator to access zones where risks of electric shock are present must be
performed with the machine off.
REMOTE ASSISTANCE: The machine may also be remotely activated via Personal Computer or
Smart device. Pay maximum attention during access to dangerous areas.
