Assembly
Getting started:
Your Exposing Unit has been fully assembled and tested in our factory. Both lid lifting cylinders have
been removed from their upper mounting stud and secured to the side of the cabinet. Be careful not to
damage the rubber vacuum blanket when removing the Exposing Unit from it's crating.
It is best to keep the lid locked closed when lifting the exposing unit. Carefully remove the unit from its
crate and place it on a suitable surface. It is important that the surface be flat, an uneven surface can put
stress on the glass causing it to crack.
Placing the equipment into service and operating the equipment:
To place equipment into service, follow steps 1-4 on Page 5
To operate your exposure unit, follow the instructions on Pages 6-8
For troubleshooting and maintenance instructions see pages 9-12.

Sequence of Operation
1) Raise the exposing unit lid and wipe the glass
surface clean with a lint free rag.
2) Position the screen with positive attached, onto
the glass and against the two back screen
stops.
Do not position any screen outside screen area
indicated by the blue tape. Damage to vacuum
blanket can result.
3) Lay the small string attached to the rear of the
exposing unit over the edge of the screen to
assist in achieving a good vacuum in the center
of the screen.
4) Lower the lid and lock closed with both
handles.
5) Turn on the power switch.
6) Set the Vacuum Time. (See Touchscreen
Controls).
7) Set Exposure Time. (See Touchscreen
Controls).
8) Start Exposure Cycle. The vacuum pump will
start. After the vacuum timer has reached
preset time the UV lights will start. After the
exposing time has expired, the lights and
vacuum pump will automatically shut off. The
screen is now exposed.
9) Unlock the lid to break the vacuum and remove
the screen.
Tips
Vacuum Time: (for each size screen)
Lock lid and set vacuum time to 90 Seconds. Start
cycle and record the time it takes to flatten the
blanket to a size larger than your positive. If unsure,
wait until blanket is flat to within 2” (5cm) of frame.
Exposure Time:
A full and complete exposure will be effected by
several variables listed by importance.
1) Type and brand of emulsion
2) Thickness of stencil (qty. of coats or capillary
film thickness)
3) Mesh color
4) Humidity
For this reason the only proper way to determine
the correct time for a full and complete exposure is
to use a “Exposure Calculator”. Several types of
calculators are available, contact your supplier to
determine which is best for you.
Approximate setting for single part or “Pure
Photopolymer” is: 10 – 30 seconds. (LED)
Approximate setting for “Dual Cure”: 60 – 300
Seconds. (LED)
Overview:
Your Exposing Unit is equipped with UV Lights, a vacuum pump, and touchscreen controls to digitally
set vacuum and exposure times.
The vacuum pump draws the air out from between the blanket and glass. This flattens the coated
screen and positive to the glass making for a sharper exposed image.

Glass Removal / Installation
There are three glass retainers. One on each side
to square the glass to the rear seal and one in the
front with special cams. The cams are used to
gently push the glass back against the rear seal.
1) Remove the cams and front retainer. Slide
the glass towards the front to remove.
Carefully set glass on a flat, protected
surface. The cams are used to gently push
the glass back against the rear seal.
2) It is important to keep the inside of the
cabinet clean. Vacuum out any loose debris
from inside the cabinet. Refer to the replacing
a light bar if needed.
3) Reinstalling the glass.
Before installing the glass, switch the vacuum
pump on and off to verify it is functioning
properly. Clean both sides of the glass with
glass cleaner and a lint free rag. Vacuum
inside of cabinet. Position the glass seal side
down, blue tape towards the front, on the
front edge of the cabinet, and between the
side retainers. Slide glass back until it
contacts and it seated squarely against the
back seal. Place the front glass retainer and
the three cams against the glass front. Install
the screws but only snug the screws. Using a
1/4” flat screw driver in the cam slots, rotate
each cam to push the glass back. Do not
over tighten the cams but apply enough
pressure to make a seal. Now tighten the
center screws. If the vacuum leaks, go back
and tighten the cams a bit more.
4) Inspection of LED light bars should be
conducted monthly. See page 11, Step 1,
for instructions.
Inspection of UV Black bulbs should be
conducted bi-monthly. See page 12, Step 1,
for instructions
Note: The glass must be tight
against the back glass seal in
order to make a good vacuum.
Special cams help to apply
pressure. Do not over tighten.
Wear gloves when handling the
glass. Glass is tempered and
although strong, can shatter if the
edges are subjected to an impact.
Do Not allow objects to
contact the UV lights.

1) Verify that vacuum pump is running.
2) Examine the rubber blanket for holes or cuts.
3) Check that the holes in the back left screen stop
is not blocked. Turn on the pump and verify that
there is vacuum through the left stop.
4) Check that the clear tube protruding through left
side of cabinet wall is unobstructed. This is the
vacuum pump exhaust.
5) Verify that the back glass seal is not damaged.
If it is not try tightening the front cams just
slightly. If this does not work, pull the glass away
and inspect the seal, then reseat the glass
squarely against the back seal and retighten the
front cams.
6) There is a foam seal around the perimeter of the
lid between the rubber blanket and lid frame.
With the lid locked down, check that the lid seal
and blanket is contacting the glass at all four
sides. If this seal is not contacting the glass it
will be necessary to adjust the lid lower.
Proceed as follows (pictures below for
reference).
a) Remove both Lid Lifting Cylinders from their
upper mounting stud. Carefully lower the lid.
b) Rear Seal Adjustment. Start with the lid
down and locked. Using a 1/2" wrench,
loosen the top nut 1/2 turn then tighten the
bottom nut 1/2 turn. This will adjust the lid
down .025". Do this to both sides until
vacuum seal is achieved
c) Front Lid Adjustment. Using a 9/16
wrench, loosen (2) bolts at each front corner
about 1/8 of a turn. Using a piece of wood
and a hammer, tap on the top bolt head
slightly to move the bearing down. Be
careful to avoid moving it too much. For
reference, measure from the top of the
bearing to the bottom of the lid when closed,
do not adjust more than 1/16 of an inch.
Retighten all fasteners.
7) Contact Vastex for technical support if these
steps fail to resolve the problem.
