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 let the machine OFF.
• In the canisters, stirring of each colorant takes place automatically (stirring times can however be
customized).
• Be careful not to ll the canisters with too much colorant. In case of overlling, act 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 right 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
• Rell 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.

3.2 Description of units
Canisters
The machine canisters are suitable for containing the product to be dispensed.
Covers in the upper part of the machine provide access for lling the canisters.
Nozzle Center
The ends of the dispensing pipes coming from the canisters converge and
are xed 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 Lift manual shelf is xed to the machine and can be raised or lowered
by the operator. The shelf is provided with a locking handle that must be
pulled to release the shelf and allow it to be moved to the desired height.
Can centering device
The can centering device is useful for positioning pre-punched cans right under
the dispensing center and is custom-made based on the size of the cans to be
handled.
Bung Hole Locator (B.H.L.)
This is a system that emits laser beams that allow the positioning of pre-punched
cans, so that the hole is in line with the center of the dispensing nozzles.
COROB™ FLEX 900
Page 15
FEATURES - 11
Nozzle Humidier 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 humidier 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 conrms the can presence to begin dispensing.
The Sliding Autocap is an automatically activated cap, whose movement
is managed by the application program, which opens it automatically
before dispensing and closes it automatically immediately afterwards. A
photocell prevents dispensing from taking place when no can is resting
on the shelf.

5.7 Shut-down
WARNING
WE RECOMMEND THAT YOU NEVER SHUT DOWN THE MACHINE, even when closed for business,
because the automatic, timed functions help keep the colorant preserved and homogeneous.
Should it be essential to shut down the machine, avoid keeping it off for extended periods of time. When the
machine is not being used, shut off only the computer.
Very little power is used by the machine itself when inactive or during a stirring cycle.
Shut off the machine as follows:

6.1 General warnings
DANGER
The machine must be used by a single operator.
It is strictly forbidden to bypass and disable the safety devices and protections.
Do not, for any reason, place your hands in the dispensing area when running the machine, except for loading
and unloading the cans.
The panels must be kept closed at all times.
6.2 At the beginning of the working day
At the beginning of each work shift, always carry out the following operations:
• 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.
6.3 Running the machine
The operator is guided in running the machine by the COROB™ management software, which displays the
instructions to be carried out and the actions performed by the machine.
Steps Options Reference
Make the selections from the management software
(selection of the product, formula and cansize).
Adjust the height of the can shelf. chapter 6.3.1
Load the can in the machine. chapter 6.3.2
Adjust can position with respect to the dispensing
center.

6.3.1 Adjusting the can shelf height
1. Release the shelf by pulling the handle.
2. Raise or lower the shelf, adjusting its height
based on the size of the can to be used.
3. Release the handle to lock the shelf in the
desired position.
Figure 11
WARNING
With sliding cap: the shelf position must be such that it allows the can -- to be lately placed -- to push the
cap opening bar.
With sliding Autocap: the shelf position must be such that it does not cause the can to interfere with the
opening movement of the autocap, but must anyway ensure proper engagement of the photocell.
6.3.2 Loading the can
with sliding cap with sliding Autocap
Place the can on the shelf to push the cap opening bar
inward and thus cause it to open.
Place the can on the shelf, making sure that photocell
(A) is obscured.

6.3.5 Dispensing
When the dispensing command is entered, the Autocap (if present) opens to expose the nozzles and the machine
begins to dispense the products included in the formula in the set amounts; the Autocap will automatically close
when dispensing is nished.
The dispensing system depends on the machine version (sequential or simultaneous).
6.4 Automatic timed processes
Colorant stirring is a timed process, activated automatically to properly store the product in the canisters and
keep it in ideal, homogeneous conditions for dispensing, through the movement of stirring paddles inside
canisters.
The recirculation process circulates the colorant through the dispensing circuits, avoiding pigment sedimentation
in the various parts of the circuit. The colorant leaves the bottom of the canister and returns in the canister
through the recirculation connector, without being dispensed through the nozzle center.
The duration and the interval between one stirring or recirculation cycle and another can be customized via
the conguration software (refer to the CorobTECH user’s manual), based on the nature of the products used
on the machine.
We recommend to keep the canisters closed with their corresponding lids; do not insert hands in the
canister even when no colorant is present.
When an automatic timed process is in progress, the machine can still be used; the process will be suspended
and restarted after a few seconds that the machine is inactive.

1. Push the off-line button for an instant (chapter 5.6).
2. Open the upper covers.
3. Remove the lid of the canister to be lled.
Shake the container of colorant to be poured into the canister manually. Do not use automatic shakers.
4. Make sure that the bottle draining system is correctly positioned, then add the desired colorant to the
canister, by pouring it directly on the bottle drainer, so as to avoid spattering or creating air emulsions in
the colorant.
WARNING
To avoid colorant spills from the shaft of the stirring system, it is essential that you DO NOT REMOVE the
bottle drainer while topping up. The colorant level MUST NOT exceed the maximum level, placed at 6 cm from
the upper edge of the canister. Colorant spills cause the circuit pumping unit to be blocked.
5. Close the canister with its corresponding lid.
6. Repeat the above steps to ll other canisters.
7. Close the upper covers and restore the machine by pressing for an instant the off-line button (chapter 5.6).
COROB™ FLEX 900
Page 34
30 - USING THE DISPENSER
8. Update the colorant level value for the topped up canisters in the machine management software (refer to
the software user’s manual).
WARNING
In case of improper actions, which caused canister overlling with colorant:
• In case the colorant has poured inside the machine, do not try to clean; turn the machine off at once and
contact an authorized service center.
• If, on the contrary, the product has already poured out of the canister, it is necessary to shut off the
machine immediately and clean with paper or a moistened cloth. Whenever possible, leave the colorant to
dry itself and remove with a spatula.
• If the product has not yet come out of the canister borders, it is necessary to avoid closing the canister
with its lid and provide immediately to dispense the exceeding colorant until the correct level is reached.
Clean carefully the upper border of the canister with paper or a moistened cloth before closing it with the
lid.
NEVER USE WATER OR SOLVENT-BASED CLEANING PRODUCTS TO CLEAN THE MACHINE.
DANGER
When using colorants containing volatile solvents the canister top up must be carried out opening one
canister at the time.
WARNING
Failure to update the colorant levels in the canisters may compromise the accuracy of the hue produced or,
worse yet, lead to emptying the machine canisters and circuits.
If “SOLVENT FREE” colorants are used, or those that dry out quickly, we recommend that you keep the
canisters full at all times by topping up frequently.
After topping up the colorant, it is advisable to carry out the stirring process using the functions provided in the
management software, to eliminate any air that may be emulsied and incorporated into the colorant.
Here below you will nd a reference diagram to perform canister lling.
