20 - START-UP
5.4 Initialization
INITIALIZATION is a preparatory phase that must be carried out when the machine is turned on.
If the computer is turned off and back on again, initialization is not strictly necessary, even if required
by the software; it is solely at the discretion of the operator.
Moreover, initialization must be carried out in the following cases:
• At the beginning of each work shift, even if only the computer had been shut down.
• To send new operating parameters set via the management software.
For more information about the Initialization function, refer to the software user’s manual.
5.5 Use of the off-line button
When the off-line button is pressed, all functions of the machine are interrupted; the ON lamp blinks to indicate
that the machine is switched on but with the functions blocked. In these conditions, any commands coming
from the computer are refused.
After interrupting the machine functions, it will be possible to carry out canister relling.
The status of the ON lamp highlights the condition in which the machine is:
Status of the ON lamp Meaning

6.3.4 Dispensing
When the dispensing command is entered, the machine begins to dispense the products included in the formula
in the set amounts.
The dispensing system depends on the machine version (sequential or simultaneous).
6.4 Automatic timed stirring
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 duration and the interval between one stirring 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 (chapter 5.5).
2. Open the machine upper cover.
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 5 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 machine upper cover and restore the machine by releasing the off-line button (chapter 5.5).
28 - 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.
