requirements; the CE marking certifies its compliance.
All measures and precautions were taken during its design, manufacture, testing and installation
to ensure the highest possible level of safety considering rational use of the machine.
The warnings listed below are to be considered general in nature; specific safety instructions
related to the type of intervention to be carried out and the type of accessories installed on the
machine are given in detail in the specific paragraphs.
R E A D T H E S A F E T Y W A R N I N G S C A R E F U L L Y

WARNING WARNINGS WARNING
Do not operate near the plant without suitable personal protections such as:
glasses
protective suit (against chemical agents)
safety shoes
Do not operate the machine with permanent and/or movable protections disabled
When the Compacta is connected to the main power it will perform the automatic timed
controlled process of re-circulation and stirring at pre-set intervals. This involves sudden
activation of the pump motor during the re-circulation process and the sudden activation of
the stirring motors during the stirring process
The customer must make sure that environmental conditions and power supply conditions
where the machine operates are always in compliance with the instructions of this manual.
Do not disable safety precautions installed on the machine
Do not modify for any reason any part of the machine (joints, holes, finishing, ... ) to adapt
additional devices . (We advise to ask for modifications directly to DROMONT S.p.A.)
Clean machine coverings panels and commands carefully, with dry and soft cloths, or lightly
soaked in a non-flammable detergent.

4. FEATURES
4.1 General description
The Compacta is an automatic dispenser with innovative architecture, it operates up to 32
internal circuits and supports both simultaneous volumetric and gravimetric dispensing and
combined operational modes.
The Compacta uses the piston pump technology combining high accuracy with low wear.
picture 4-1 shows the working principle of the machine.
picture 4-1 working principle and fluid flow
The principle is basically as a bicycle pump: the pump (03) goes down which creates a
depression in the piston volume. Due to this depression the colorant will pass from the canister
through the filter and the three-way valve (02) to the piston. When the piston goes up it will push
the fluid back to the canister (in recirculation) or it will go to the dosing head (04) passing
through the three-way valve.

4.4 Features and options Compacta
4.4.1 Canisters
The Compacta has a fixed combination of canister sizes of 3 and 5 liters.
The canisters can be chosen in plastic (POM) or stainless steel (depending on the type of
colorant) and are compatible with every type of colorant. Each canister has a stirrer that stirs at
20Rpm during the re-circulation or a dosing cycle. As you can see in picture 4-4 the stirrer has
been developed to guarantee the best mixing avoiding settling or the drying of the colorant. The
stirring motor is independent and very easy exchangeable.

4.4.4 Elevator
On the Compacta dispenser two different types of elevator can be installed: manual or automatic
version.
Manual elevator
The Compacta is equipped with a manual shelf. Highering or lowering the shelf can be done
tearing the handle that you'll find on the bottomside of the shelf. After the shelf is positioned in
its position the handle is relieved and the shelf will be blocked in its position.
Automatic elevator
The elevator has a motor integrated which highers/lowers the cans until they are detected by the
photocell . Operating the elevator is very easy and effortless: just pushing the vertical arrows on
the display moves the elevator up and down.
The elevator stops automatically when the photocell detects a can.
4.5 Options
4.5.1 Printer
There is the possibility to connect a printer to the Prima software. Follow the instructions for
installation that comes with the printer and read the software manuals.
