only an exposure unit, no washout or drying. You can expose liquid
photopolymer using the glass sandwich above the bank of UV tubes, or
expose sheet photopolymer in the vacuum unit beneath them. There is a
three-unit digital timer for exposure, with readout in seconds, and
you just push those tiny buttons to set each number, say 240 for 4
minutes. There are safety switches connected to the top cover and the
two drawers that will shut off the lamps if opened so your skin and
eyes aren't exposed to a very dangerous part of the light spectrum.
The vacuum drawer has a removable bottom, handy when replacing the
cover sheet or cleaning it, and needs to be seated correctly against a
rubber o-ring to get a proper seal for vacuuum drawdown.
If there is anything wrong with the electrical components you may
have your work cut out fixing them.
