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.
Select 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.
