All other application need our written consent or happen on risk of the operator.
The Bungard GmbH & Co. KG accepts no liability for damages incurred in non-authorised use or
application of the machine.
Safety instructions
Generally
Please read the following text carefully and pay particular attention to the information on
occupational safety and commissioning.
Please keep this folder carefully. It contains information that is also important for later
maintenance or cleaning work.
The machines are not intended for integration or interconnection with other machines or
systems. They may only be operated in rooms equipped for this purpose and may only be
operated by qualified specialist personnel. Keep children and pets away!
The Hellas is designed for use in the laboratory. The device may only be serviced by a qualified
specialist. The user should never try to do more for the maintenance of his device than is
allowed to do according to the operating instructions. He should always consult a specialist for
maintenance work that is beyond his authority.
transport
Use only suitable lifting and transport equipment such as forklifts or pallet trucks. ecure the
machine against slipping / tipping. Risk of damage!
site
The machine needs a flat table of approx. 700 x 800mm. There must be sufficient space
around the machine for operation and maintenance.
Do not place the device near heat sources such as radiators, warm air ducts, ovens and the
like.
The installation environment is crucial for problem-free work with the Hellas. You must therefore
place particular emphasis on a room that is as dust-free as possible and room air free of
corrosive vapors in order to ensure that it functions properly.
Electrical
The machine is manufactured using tested parts according to the usual guidelines for electrical
safety. However, this does not release the user from his duty of care when handling electrically
operated devices.
Only connect the device to the power source marked in the operating instructions or on the
device. We assume that the power source will be protected on-site. The connection to the
power supply may only be carried out by a specialist.
The circuit and the fault circuit must be protected by the customer.
Before starting any work on the machine (cleaning, etc.) and when not in use for a long time,
switch off the machine and pull out the mains plug.
fluorescent tubes
Due to the high intensity of the emitted light, it is u. It may be uncomfortable to look into the
fluorescent tubes that are switched on. However, the danger of the emitted UV light is just as
low as that of tube-equipped tanning devices. Intended use is in the closed state to avoid eye
injuries
Avoid contamination with iron chloride. Because of its reddish-brown color, they lead to a partial
absorption of UV light.

cleaning
Follow the manufacturer's recommendations when cleaning the device.
vacuum
The thickness of the workpieces to be processed should not exceed 5 mm, as otherwise the
vacuum may be impaired or the vacuum film may even be damaged. For this reason, no sharp
objects may lie between the glass plate and the vacuum film when the vacuum is switched on.
Also make sure that the vacuum hose, which opens into the glass plate (Hellas-E: aluminum
plate) at the front left, is not blocked by objects.
work safety
Do not look into the UV lamps! Intended use is carried out in the closed state to avoid eye
injuries.
protect from moisture
Protect against falling
Only open the lid briefly for loading (prevent it from falling).
environmental Protection
Attention: Fluorescent tubes must be handled with care and disposed of as special waste
according to the rules of waste disposal. If the lamp breaks, be sure to consult your safety
officer and wear suitable protective clothing to avoid serious damage to health.
Set Up
The unit should be put onto a table in a way that it can be accessed from the front. Please keep a
distance of 30 cm from walls, radiators etc. and make sure that the cover can be easily opened up
to a vertical position.
If you encounter any transport damages be sure to directly inform us and the carrier.
Remove the tape locking the cover and verify that the fluorescent tubes have not been damaged
during transport. To do so, take the cover's handle and lift it so that the cover stands vertically on the
rear mounted rubber pads.
Looking onto the lower part of the set, you can see the vacuum frame with its polyester foil spanning
over a crystal glass plate. Please check the foil, the frame and the glass plate for any damage. You
may lift the frame vertically so that it leans against the upper part of the unit. Using a soft cloth,
please remove dirt or rests of packing material from the foil and the glass plate.
To check that the electrical components of the unit work correctly, please follow the operating
instructions given here below. The set requires a 230 V, 50 Hz main supply.
Operating
Put the cover and the vacuum frame into a vertical position. Place the board to be exposed onto the
glass plate. Be sure to have removed any protective foil from the board. Place the artwork onto the
board. For double sided boards, we propose that you mount the top and bottom artwork on an L-
shaped carrier so that they superimpose and form a "bag" with lateral stops for the board. You will
have best results with the emulsion side of the artwork (film) lying directly on the photoresist. Take
care not to enclose dust particles between the board and the artwork.

Now slowly return the vacuum frame into its horizontal position. (If any displacement of the artwork
has occurred, reopen the frame and rearrange the artwork.)
Locate the switches, the timer, the ampere meter
and the vacuum control on the front panel of the
unit (Hellas-E: no Amperemeter). All to the left,
there is a switch controlling the vacuum pump. Put
it into its ON position. The pump will start running
and the indicator lamp in the switch will light.
Within a few seconds, the pump will have
evacuated the air between the frame and the glass
plate. The vacuum indicator will show approx. 0.8
bar.
The polyester foil is structured to allow an easy
and complete evacuation on the whole surface.
Nevertheless, there might remain an air cushion
between the artwork and the board. Wipe over the
polyester foil with your hand or with a soft cloth to remove any rest of air. Using the handle, smoothly
close the cover.
elect single or double side exposure by turning on the appropriate switches for the upper and lower
set of tubes. They are located to the right of the timer. Hellas-E: You may switch on only the upper
unit.
To start the exposure, follow the instructions below to operate the electronic timer. Alternatively you
can operate Hellas in continuous mode. To do so turn on the switch left to the timer. Turn the switch
off to stop the continuous operation mode. The indicator lamp in the switch is lit during automatic
exposure and continuous operation as well. The switch is marked ventilator to indicate that there is
a built-in fan always running together with the lower tube set. Hellas-E: there is no switch for
continuous exposure.
Timer
The exposure time is controlled by a digital-read-out and digital-adjustable timer. The range of time
is from 1 second to 9 minutes 59 seconds. The device supports easy time pre selection and recall
by one hand operation and can be run in stop-and-go turns.
On the timer front panel there are the LCD time display and the three buttons MODE, + and -.
To adjust the desired exposure time, press the + or - buttons accordingly. Keeping one of them
down makes the settings change faster.
To start exposure, press the MODE button once. The remaining time is displayed continuously on
the LCD display. The process is interrupted and restarted for the remaining time at each time the
MODE button is pressed. The timer beeps several times when exposure has finished.
To redisplay the previous setting, press the MODE button once. You may then use the +/- buttons to
change the setting or just restart the unit by pressing the MODE button.
Do not switch off the vacuum during exposure! With the artwork loosing contact to the board, severe
under-cut may result.
When having completed the exposure, open the cover, switch off the vacuum and open the frame.
Never lift the frame with the vacuum pump running. Abnormal usage of the frame would result.
The intensity and spectre of the UV light from the fluorescent tubes can be compared to that of skin
tanning sets: It may irritate your eyes. You should therefore avoid to look directly into the light for a
longer time.

Maintenance
There is only little maintenance necessary for the HELLA exposure set. The vacuum pump, for
instance, is maintenance free. To protect it from dirt and dust, there is a filter put in front of it.
The fluorescent tubes are subjected to wear. After about one or two years, they should be replaced.
A reduced Amps reading on the emission control meteor dark shadows appearing at the tubes
ends indicate that they should be renewed.
To do so, at first disconnect the exposure set from the main supply. Carefully lift the crystal glass
plate and pull off the small blue vacuum hose to get access to the lower tube set. Turn the tubes
along their axis until they snap off from the fittings. Replace them only with tubes of the same type
and strength. Check that the new tubes are well locked. It is recommended also to replace the
starters.
We want to tear your special attention to a careful maintenance of the vacuum foil. It should be
cleaned regularly using water and a soft detergent. Do not use solvents.
Be extremely careful not to contaminate the foil with spots of developer or etching liquid.
Do not put pieces with an height of more than about 5 mm under the frame. This could lead to
serious deformation or even cuts in the foil.
