1. DESCRIPTION
1.1 PURPOSE OF USE
PHOTOPOL Digital has been expressly designed to carry out curing operations under the effect of ultraviolet rays.
The system has been developped to suit with the requirements of Dental, Jewellery and Rapid Prototyping
laboratories for the hardening (post-curing) process of objects manufactured with 3D DLP printers which use
liquid resins and for the final stabilisation of photosensitive composites. The UV spectrum range achieved by this
unit corresponds to the specific value of those resins (from 320 to 450nm) thus assuring to reach the complete
result.
The curing process of PHOTOPOL Digital is performed in a wide working chamber, the radiation sources have
been uniformly distributed on all walls assuring to reach the objects from any direction.
All functions are controlled and run by an electronic microprocessor circuit. The operating software features a
logical user interface providing ease of use and immediate understanding. All operating data are always clearly
displayed and can be modified directly on the full-colour touch screen.
The unit works under independent condition, it may not be supervised by the User himself therefore no defined
working place is required.
1.2 IMPROPER USE
Do not use the UV radiation performed by this unit for any different purposes of use not herewith stated; the
manufacturer will assume no liability further to improper use of the unit for any damage which could incur to
persons, animals or things.

Installation of this ma
chine is quite easy but it must be carried out paying utmost a
ttention
in order to avoid any mistake which may originate problems during operation,
inconvenience or even damages.
Store the original package of the unit for any further handling or shipment under exraordinary maintenance
intervention. Remove the protective foils all around the metallic housing and inside the transparent shelves
positioned at the inside of the working chamber.
1. Place the machine on a suitable work bench, in a stable position appropriate to its weight, at least 10cm away
from the wall to allow the necessary space for the connections. During operation no vibrations are originated,
therefore no additional precautions are required at installation
2. Check the plate data, referring to the electrical feeding and the absorption then feed the unit through a
protected line by 10Amp magneto-thermic bipolar switch and circuit breaker with 30mA sensibility (devices
not part of the supply)
3. Connect the feeding cable (A) to the socket (B) placed on the right side panel and plug the other end into an
approved 230v AC - 50Hz socket with ground connection
4. Switch on the unit (C), the display (D) will light up.

7. SETTING THE WORKING CYCLE
From the main menu select the central icon PROGRAM STORAGE
Find a free number to be attributed to the program (at the beginning they
are all free, once the cycle contains some stored data the V combined to the
number will turn from green to red), START will appear allowing the
immediate execution with no need to browse all parameters
RIGHT ARROW to next page
When setting a working cycle some important parameters have to be selected:
1. Environmental condition (namely the quality of site where the curing will be carried out – highly
important for resins in class IIa)
2. Applied voltage (speed and intensity rate the LEDs will be working at)
3. Working time (length of the irradiation step)
The preparation of a polymerization cycle starts with the choice of the
WORKING CONDITIONS, the selected symbol will turn darker.

8. INSTRUCTIONS FOR USE
1. Switch on the main switch, the display will light up and the unit is ready to input
the operating data, touch the display to access the main menu
2. Click the central icon ARCHIVE, select the desired working cycle or create a new
one if the cycle had already been stored and data should not be modified, the
start up procedure can be activated right away by pressing START at the top
3. Open the lid to access the inside of the working chamber and position the objects
to be treated, then close it completely (in case the lid is not fully closed the
working cycle will not start)
4. Press the green start up key.
When the lid is opened the cycle will be immediately interrupted and once closed it will restart from the step it
had been cut off.
Once the cycle is definitively completed, the unit will emit a sequence of sound signals. When the lid is opened to
pick up the object, parameters will be reset to zero and the furnace is ready for a new cycle.
In case of voltage drop during the cycle, it will cause it to stop permanently and can not be recovered, as a
consequence it is recommended to protect the unit with an Uninterrupted Power Suppply (UPS) to avoid
wasting the objects as a result of an incomplete treatment (in any case a structural verification of the treated
objects is always recommended).
9. CHECK OF LED CONSUMPTION
The partial or complete deterioration in performance of the UV LEDs will cause the failure or partial curing of the
treated objects, the result is clearly visible (the object is not hardened or moist) or emerging in the following
treatments (finishing). To help prevent this problem it is necessary to check always the efficiency (test cycle and
visual inspection of the treated objects). In addition the software manages a control system on LED consumption.
As the
deteriorat
ion level is approaching,
a warning symbol will
appear on the display
; operation is
still allowed by slightly extending the working time. Spares replacement is promptly recommended.
After an additional
short period, a
b
an symbol i
s shown locking the unit and forcing the technical
intervention.
10. MAINTENANCE
/!
\
ATTENTION:
Before c
arryin
g
out any maintenanc
e operation inside the machine
, unplug the
e
lectric
cable from the socket; in such a way the machine will be completely insulated from the
electric wiring system. If you still have any doubts, difficulties or any possibility of mistake,
contact our Technical Service to avoid any risks or damages.
Any technical intervention involving to remove the protections and to manipulate the
machine internal components can be carried out exclusively by skilled personnel or staff
trained by the Manufacturer.
Cleaning of the working chamber
It is advisable to keep always clean the internal surfaces of the working chamber to allow the correct refraction of
the emitted rays; be careful to use exclusively non-aggressive liquid detergent specific for glass and PMMA
(absolutely with neither abrasive components nor alcohol).
