The Lumitron is a high end exposure system in a small package. This unit has high output UV uorescent bulbs that oer balanced
light distribuon throughout. Using the same powerful vacuum as our larger units, the Lumitron gives you perfect contact between
your lm posive and screen.
The Luminator is an expandable exposure unit specially designed for the startup shop on a budget. This unit has high output UV
uorescent bulbs that oer balanced light distribuon throughout. This system is compable with direct emulsion or capillary lms
that allow versality in your stencil systems. It comes standard with a 16 x 20" pressure pad to ensure even contact between your
lm posive and your screen.
Introducon:
Standard Operang Guide:
Plug in the unit, make sure it is plugged into a 3-wire grounded circuit (115 or 220 volt) depending on which machine you have. If
you are unsure of the power requirements please call Workhorse Products 1-800-778-8779
DO NOT ALTER OR MODIFY THE PLUG IN ANY WAY!
Turn on main power rocker switch unl it lights up. Release the single latch and open the vacuum frame and place the coated, dry
screen, print side down in the center of the glass with the lm or vellum underneath, either taped to the glass or taped to the print
side of the screen. (For opmum performance, place your screens in the center of the unit above the light source) Place one end of
the rope next to the vacuum nipple located toward the rear and in the center of the vacuum frame, drape the other end of the
rope across the inside (squeegee side) of the frame. This will allow all of the air to be evacuated out of the inside of the screen and
provide necessary contact between your lm or vellum and the emulsion. (Do not place the rope directly under the vacuum nipple
as this will reduce the vacuum speed and could negavely aect your blanket to screen contact)
Close the vacuum frame and lock it into posion with the single latch, then turn on the unit , the vacuum will automacally come
on. Wait unl the blanket has drawn down around the screen completely before you start your exposure. The vacuum motor will
change sound slightly as it goes into idle mode. Once the exposure mer has beeped indicang its nish, turn o the vacuum
rocker switch and release the latches. Open the vacuum frame and remove your screen.
NOTE: Open the frame slowly as screens can get stuck to the vacuum blanket due to tape, ink residue or wet emulsion( Keep your
screens as clean as possible and inspect your frames periodically for sharp edges and splinters. This will aid in keeping your vacuum
blanket and glass clean, and prevent wear on the vacuum blanket).

FAQ:
1. The vacuum is taking along me to remove all of the air.
This can be caused by incorrect placement of the nylon cord. The nylon cord is used to create “paths” for the air to escape from the
center of the screen. Place one end of the rope next to the vacuum nipple located toward the rear and in the center of the vacuum
frame, drape the other end of the rope across the inside (squeegee side) of the frame. This will allow all of the air to escape out of
the inside of the screen and provide necessary contact between your lm or vellum and the emulsion. Do not place the rope
directly under the vacuum nipple as this will reduce the vacuum speed and could negavely aect your blanket to screen contact
If the nylon cord is properly placed, check the adjustment of the vacuum frame clamps, if out of adjustment ghten the nylon lock
nuts an equal amount of turns on each one and try closing the frame. If it takes an excessive amount of force to lock them down
back the nuts o and try again. They should be rm but no excessive to ensure a ght seal is formed. Also check the clear vacuum
line running from the vacuum pump to the modied stem (Image 1) Check for kinks or disconnected lines, if necessary un-kink or
replace vacuum lines. Image 1
2. The bulbs in my exposure unit are ickering (When I touch them they stop)
This is caused by improper grounding. Make sure the receptacle that the unit is plugged into is properly grounded. Also have an
electrician check the building ground.
Another Symptom of a bad ground is when the mer is acvated only some of the lights come on.
3. One of my bulbs is not coming on.
This may be cause by a bad ballast. To test the bulb/ ballast with power to the unit o, remove the non-funconing bulb and swap
it with a known working bulb. Turn the unit o, if the if the posion of the non funconing bulb has not changed the ballast
controlling that bulb is bad.
If the posion of the non funconing bulb does change, the bulb will need to be replaced.

3. (Connued)
To replace the ballast, rst remove the glass. Next, Idenfy which bulb is not working (See page 14, Ballast to Lamp Relaonship)
Lamp #1 Lamp #2 Lamp #3 Lamp #4 Lamp #5 Lamp #6
Image 2
Next locate the ballast covers located on the le and right sides. The posion of the non funconing light will determine which
cover to remove. If the non funconing lamps are 1, 2, or 3 the le cover will need to be removed. If the non funconing lamps are
4, 5, or 6 the right cover will need to be removed (Image 3 and 4)
Image 3, Le Ballast Bank, Lamps 1-3Image 4 Right Ballast Bank, Lamps 4-6
With the correct cover now removed, using the guide one page 15 to locate the faulty ballast. Once idened take notes of how
the original ballast is wired, then, with the unit unplugged remove the ballast and place the new ballast in the same locaon.
Connect the new ballast the same way the original was, if the correct plugs are not present on the new ballast use wire nuts to
secure the wires together. Replace the covers and glass, then plug the unit back in. With the new ballast installed the unit is now
ready for use.

4. The mer starts to countdown but no lights come on.
This may be caused by a faulty mer. To test the mer remove the glass, located at the front of the unit the mer will now be
exposed (Image 5)
(Image 5)
Locate the terminals marked #3 and #4, with power to the unit o, using a blade style fuse (Image 6) most commonly found it
automove applicaons, jumper the two wires together. Now turn the unit on, if the lights come on the mer will need to be
replaced.
(Image 6)
5. The vacuum pump is not running.
With power to the unit o, unplug the vacuum from the rear of the unit. Next plug the unit into a receptacle in the building. If the
vacuum sll will not run the vacuum will need to be replaced.
If the vacuum begins to run, with power to the unit on, using a digital Volt/Ohm meter in the ACV (200 –750) seng, place one
probe in one side of the receptacle and the other probe in the other (Image 7) the meter should read 115v-120v AC. If not turn the
unit o and check the receptacles for loose connecons.

Seng Interval Timer: In modes 1 – 3, the device funcons as a simple countdown mer. When you set the value, press the Start/
Resume buon. When the value reaches 0, the relay is turned OFF and the beeper beeps 6 sets of 2 (250ms) beeps.
To enter one of the 3 countdown modes, press and hold the Mode buon for 1 second. Holding down this buon the mode will
switch every 2 seconds. Each me the mode switches, the appropriate LED of mode LEDs will be turned ON and the value displayed
will change to the modes default value. An audible ¼ beep will also be heard.
Once the countdown value has been set, you can now start the mer by pressing the Start/ Resume buon, the relay is turned ON.
While the mer is counng down the user can stop the event by pressing the Stop buon. The current countdown value will
remain on the display. If you want to resume the session you just need to press the start buon again. Counng will proceed from
the point where stopped. During this operaon, the “run” LED blinks once a second. Once the mer has counted down to 0 and
stopped, you can execute the same session (me value) by pressing the [START/RESUME] buon again. This will recall the mer
value and display it. At this point, you have two opons. The rst being the ability to change the value by using the Increase or
Decrease buons and the second being the ability to use the same value and starng the event again by pressing the
Start/ Resume buon.
Mode 1: 0 – 99 second: DEFAULT DISPLAY = .01
Mode 2: 0 – 99 minute: DEFAULT DISPLAY = 00.00
Mode 3: 0 – 99 hour: DEFAULT DISPLAY = 00.00
Repeat Feature: the mer will remember the last me set. To change the seng from the original seng, press start switch to
recall previous seng then input new seng.
Before using exposure unit for the rst me obtain an exposure calculator from your supplier.
