QUICK GUIDE
At the beginning of the working day
• Check that the nozzle center is clean.
• Check that the sponge is clean and saturated; if it is necessary to saturate, use only appropriate liquid (the
choice of the liquid depends on the nature of the colorants, and must be done directly by the manufacturer
of the products used).
• Carry out system Initialization and Purge.
Things to remember
• Never turn the machine OFF.
• In the canisters, stirring of each colorant takes place automatically.
• Be careful not to ll the canisters with too much colorant. In case of overlling, refer as indicated in the
user’s manual.
• The colorant to be poured inside the canisters must be stirred manually. Do not use automatic shakers.
• Close the canisters with their lids immediately after lling operations.
• Remember to update accordingly the canisters lling levels via the management software.
• The sponge must be saturated at least twice a week (the frequency of intervention is indicative, since it
depends on the nature of colorants and the environment conditions).
At the end of the working day
• Rell the canisters.
• Update the canister lling levels in the management software.
• Shut down the computer. Do not shut off the machine.
It is recommended to carefully read the user’s manual.

COROB™ FIRST 70
3.2 Description of units
Canisters
The machine canisters are suitable for containing the product to be dispensed.
A cover in the upper part of the machine provides access for lling the
canisters.
Nozzle Center
The ends of the dispensing pipes coming from the canisters converge and are
attached to the nozzle center, from which the tinting product to ll the can is
dispensed.
Shelf
The can shelf allows for the correct positioning of the can under the dispensing
nozzles.
The Retractable shelf is removable and can be positioned at the desired
height by simply inserting it in the slots provided.
An adapter is provided to position smaller Quart (1-liter, height 100 mm)
and Pint-size (0.5-liter, height 70 mm) cans.
Nozzle Humidier Cap
Colorants tend to dry out; this tendency may be more or less strong depending
on the type of colorant and the environment conditions (temperature, relative
humidity, etc.). To prevent colorants from drying out in the nozzle center,
the machine is equipped with a humidier cap which requires constant
maintenance.
The Sliding cap is a simple cap, which opens thanks to the push applied
to the opening bar while the can is being positioned. The cap closes when
the can is removed. The system checks that the cap is properly opened
and conrms the can presence to begin dispensing.
