ELECTRICAL REQUIREMENTS
The AMERGRAPH AdVantage® 335, 340, 350, 355, & 370 SCREEN EXPOSURE
SYSTEMS are rated at 240 volts, 60 Hz, single phase power and require a dedicated
electrical service line of at least 20 amps (50 HZ units are available by special order).
Failure to have sufficient power will result in damage to the power supply and WILL VOID
THE WARRANTY OF THE UNIT. The unit must be connected to an approved electrical
ground to protect the user from electrical shock hazard. See your local electrician for advice
and service.
A wall disconnect switch for all models is recommended. All models should be wired by a
licensed electrician in order to conform to all existing local electrical codes.
Wiring for MODELS 335 & 340 should be directly to the wires accessible via the access
hole located at the right rear of the unit.
Wiring for MODELS 350, 355, & 370 should be directly into the electrical box located at
the right rear of the unit.
INSTANT START ULTRA VIOLET LAMP
Your AMERGRAPH AdVantage®SCREEN EXPOSURE SYSTEM is equipped with an
instant start U.V. lamp that only operates during an exposure. Therefore, considerable
savings in power costs result in comparison to other types of screen exposure units using
lamps which operate continuously with the aid of a shutter. In addition, via the patented
Megalumelighting system, Amergraph’s exclusive “true instant start” technology allows
the lamp to restart at all times – even while the lamp remains hot. This hot restrike feature
eliminates the cool down time required to restart the lamp for the next exposure. Since you
can reload and expose screens in rapid succession, Amergraph’s Megalumeinstant start
technology largely increases your production.

INSTALLATION
CAUTION – EXTREMELY HIGH VOLTAGE!
All AMERGRAPH AdVantage®SCREEN EXPOSURE SYSTEMS should be
installed by competent service technicians experienced in servicing and operating
high voltage, high power electrical circuits. Amergraph Corporation assumes no
liability for injury resulting from operation or servicing of this equipment.
Your AMERGRAPH AdVantage®SCREEN EXPOSURE SYSTEM is completely
assembled except for the following:
1. Lamp
2. Leveling Feet
3. AdVantage370 Step
The AdVantage370 comes equipped with a step for convenient access to
the blanket frame. It is shipped on top of the unit in separate packaging.
SELECTING THE LOCATION
Your AMERGRAPH AdVantage®SCREEN EXPOSURE SYSTEM is a compact design,
which requires a relatively minimum amount of floor space. Refer to the list below for the
width and depth of your particular unit.
MODELS 335 & 340: 37”wide x 38”deep
MODELS 350 & 355: 54”wide x 48”deep
MODEL 370: 60”wide x 56”deep
All models require 6 inches (15cm) minimum clearance at the rear and sides to allow for
blower exhaust.
The location you select is important and should be coordinated with the workflow through
your screen-making department. Proper placement of the unit will assure you maximum
production efficiency.

REMOVAL FROM THE SHIPPING PALLET
NOTE: REMOVE ALL EXPOSED EXTERNAL NAILS AND STAPLES FIRST!
1. Remove the nail and staple fasteners along the bottom edge of the shipping carton. Then
lift the shipping carton off the pallet.
2. Remove all packing materials such as tape, etc. DO NOT DISCARD ANY
PACKAGING MATERIALS UNTIL INSTALLATION IS COMPLETED.
3. Remove the 4 bolts securing the unit to the pallet. For MODELS 335 & 340 use a ½”
socket wrench. For MODELS 350, 355, & 370 use a 9/16”socket wrench.
4. Shift the unit on the pallet so that the four corners are exposed, and install the 4 leveling
feet, one in each corner. The leveling feet are packed in a bag taped inside the unit, and
MUST BE INSTALLED ON THE UNIT TO ENSURE PROPER VACUUM
DRAWDOWN.
5. You can now remove the unit from the pallet. It is advisable that enough individuals
assist in the removal by firmly supporting each corner. DO NOT LIFT THE UNIT BY
THE VACUUM BLANKET FRAME.
SET UP
NOTE: IF THE UNIT NEEDS TO PASS THROUGH A 30”OPENING, IT CAN BE
SEPARATED. SEE THE GUIDE FOLLOWING THE INSTALLATION SECTION.
1. Place the unit in the set-up location. Again, these models all require 6 inches (15cm)
minimum clearance at the rear and sides to allow for blower exhaust. Blocking of these
openings can affect the operation of the lamp and power supply, and WILL VOID THE
WARRANTY.
2. Ease the blanket frame open to its natural stopping point. Then push the blanket frame
further upward, at which time the glass frame will rise. Grab hold of the glass frame and
continue to open it to full extension.
3. Place a large size level on the top surface of the cabinet frame. Level the machine by
adjusting the leveling feet at each of the four corners, according to readings taken at the
front and sides of the top of the cabinet.
4. Check the opening and closing of the blanket and glass frames to full extension, making
certain that when closed the front sides remain even with the front side of the cabinet.
5. Open the blanket frame again, followed by the glass frame. Check the electrical and
vacuum connectors in the right front corner for full and proper connections.
6. Place the unit on a dedicated service line of at least 20 amps, as required.

SELECTING THE PROPER OPERATING VOLTAGE
***CAUTION***
This procedure should only be performed by qualified service personnel experienced
in servicing high voltage, high power, electrical circuits.
AMERGRAPH AdVantage335, 340, 350, 355, & 370 EXPOSURE SYSTEMS
operate within a voltage range of 205-245 volts. To obtain maximum operating efficiency,
an adjustment must be made at the power supply to match the normal line voltage to the
input of the power supply.
Before making any adjustment, disconnect the power to the machine by removing the wall
plug or shutting off the disconnect switch. Then remove the power supply cover plate.
For MODELS 335 & 340, the cover plate is located at the bottom rear of the unit.
For MODELS 350, 355, & 370, the cover plate is the middle panel of the front drawer. The
drawer is secured by two Allen cap screws requiring a 3/16”Allen wrench. To open the
drawer, loosen the screws but do not remove them.
Locate the YELLOW wire #14 connected to the terminal board on the power supply bearing
the tap values, 208, 220, 240 volts. After measuring the line voltage, connect the YELLOW
wire #14 to the terminal closest to the normal line voltage. Should the line voltage be
below 205 volts or above 245 volts, there is improper voltage and the unit should not be
operated until the deficiency in power is corrected. Your local electrician and power
utility can assist you in this matter.
LINE VOLTAGE TRANSFORMER TAP
205-214 208V
215-224 220V
225-245 240V
It is suggested to measure the voltage at the power outlet while the unit is operating. If the
line voltage falls into a different range than when originally measured, move the YELLOW
wire #14 to the next recommended tap.
***IMPORTANT***
Replace the cover on the power supply. Otherwise, damage to the
power supply and lamp will result from inadequate cooling.

INSTALLING THE LAMP
CAUTION!
DO NOT INSTALL LAMP UNLESS THE POWER HAS BEEN TURNED OFF AT THE
POWER SOURCE.
IMPROPER LAMP INSTALLATION WILL DAMAGE THE LAMP ENDS AND SOCKET.
DO NOT HANDLE THE GLASS QUARTZ SURFACE OF THE LAMP.
Handle the lamp only with cotton gloves or a clean cloth. If the lamp surface is
accidentally touched, wash the lamp with isopropyl alcohol to remove all traces
of fingerprints, grease or oil. (Be sure the lamp is dry before installation.) Failure
to clean the lamp will result in premature failure.
IMPORTANT:
MODELS 335, 340, 350, 355 & 370 USE ONLY AMERGRAPH LAMP P/N 10266.
THE USE OF SUBSTITUTE LAMPS will result in premature
failure and possible damage to the electrical circuitry and
WILL VOID ALL WARRANTIES!
For MODELS 335 & 340, access to the lamp holder is through the top of the unit. Open
the blanket frame, followed by the glass frame. Reach down from above.
For MODELS 350, 355, & 370, access to the lamp holder is from the bottom front
drawer, which is secured by two Allen cap screws requiring a 3/16”Allen wrench. Loosen
the screws, but do not remove them. Then pull the drawer open to expose the lamp holder.
1. Carefully slide one end of the lamp into one of the lamp clips.
2. Then gently insert, without “snapping” or forcing, the other end of the lamp into
the other lamp clip.
3. Without handling the glass quartz surface, position the lamp with the tip of the
lamp pointing up.

GUIDE FOR PASSAGE THROUGH A 30”OPENING
1. Open the blanket frame to its natural stopping point. Then push the blanket frame
further upward, at which time the glass frame will rise. Grab hold of the glass frame and
continue to open it to full extension.
2. To separate the unit into two sections, reach down into the right front corner of the unit,
and disconnect the electrical connector and the vacuum hose. For MODELS 335 &
340, remove the 4 corner screws holding the two sections together (use a 5/16”nut driver
or standard screw driver).
3. Close and latch the blanket frame before removing the sections from the pallet. Have
enough individuals assist in the removal of each section by firmly supporting each
corner. Do not lift the top section by the blanket frame.
4. Move both sections through the opening sideways, taking care to prevent movement of
the blanket frame.
5. Reposition the sections in the set up area and open the blanket and glass frames. Reach
down into the right corner and connect the electrical connector and the vacuum hose
fitting. For the MODELS 335 & 340, re-insert and tighten the 5/16”screws.

and perform the following steps in rapid succession.
Scroll to Program C; then press and hold ‘EXP SET’.
While holding ‘EXP SET’, press ‘START’.
Release ‘EXP SET’ and ‘START’. The counter will increase to a number and hold.
The number should be between 90 and 110, just as it was in the step above.
Press ‘START’. The display will read “CAL”.
Calibration is now complete. Press ‘RESET’ to resume normal operation.

BLANKET FRAME ADJUSTMENT PROCEDURE
FOR THE AdVantage®SCREEN LINE
***THIS PROCEDURE MUST BE DONE WITHOUT A SCREEN IN THE FRAME***
Minor adjustment of the blanket frame can be helpful for any loss in vacuum pressure.
The rubber on the vacuum blanket is very soft and supple, so it is common for it to take a set.
•Disconnect the power to the machine.
•Open the blanket frame.
•Use a screwdriver to remove the cap on the knuckle of the gas cylinder. (Do not attempt
to pry the knuckle off the pivot point without first removing the cap.) This knuckle is on
the pivot point attached to the blanket frame.
•Remove the knuckle from the pivot point.
•If there is more than one gas cylinder, repeat the previous two steps.
•Close and latch the blanket frame.
•On the back of the blanket frame, there are hinges that attach the blanket frame to the
glass frame assembly. There are two screws in the vertical slots on each hinge.
•Slightly loosen the screws in the vertical slots on one hinge. Apply pressure to the
blanket frame directly above the hinge. (This increases the pressure between the glass and
the blanket frame.) Tighten the screws.
•Repeat the above step for the other hinge, applying the same equal pressure as on the
previous one.
•Finish the procedure by adjusting the two front latches that attach the single bar latching
system to the frame of the unit as follows, keeping the blanket frame latched closed.
•Using a 5/32”allen wrench, slightly loosen the two screws on the one front latch. Adjust
the latch position while applying pressure to the front corner of the blanket frame. (This
increases the pressure between the glass and the blanket frame.) Tighten the screws.
•Repeat the above step for the other front latch, applying the same equal pressure as on the
previous one.
•Open the blanket and replace the gas cylinder(s).
•Reconnect power to the machine.

MAINTENANCE
Your AMERGRAPH AdVantage®SCREEN EXPOSURE SCREEN SYSTEM has been
designed to require a minimum of maintenance. Like all mechanical equipment, periodic
maintenance will prolong the life of the unit. The glass and the vacuum blanket are of
particular importance.
The GLASS should be kept clean using any commercial non-abrasive glass cleaner. Dust
particles, emulsions, or threads from screens will cause spots of unexposed areas on your
screen.
The BLANKET should be kept clean of dust by periodic vacuuming. The rubber seal
should be cleaned with blanket wash. An occasional application of rubber roller rejuvenator
will keep the seal pliable.
The VACUUM PUMP is oil-less and requires no service.
The REFLECTOR is made of a special material that reflects ultra violet light. It is therefore
important that it be kept clean. A dirty reflector will cause longer exposures and uneven
distribution of light across the vacuum frame.
CAUTION: Be certain to disconnect power to the unit before cleaning the reflector to
prevent an electrical shock from the terminals on the ends of the lamp.
Use a non-abrasive glass cleaner to clean the reflector. CAUTION: DO NOT SPRAY THE
CLEANER ON THE LAMP. Spray the cleaner on a cloth first and then apply it to the
reflector.
The EXPOSURE LAMP in your machine is designed to give you several thousand
ignitions. However, lamps are unpredictable in life expectancy, and as a result, may cease
when least expected. It is, therefore, recommended that a spare lamp be kept on hand at all
times to prevent any inconvenience when a lamp requires replacement. You can purchase
an authentic Amergraph spare lamp from your authorized Amergraph dealer.

The IN-LINE AIR FILTER protects the vacuum system from damage due to dust and dirt.
Replace the filter if it appears to be dirty. The air filter part # is 21783.
CAUTION: Be certain to disconnect power to the unit before performing any maintenance
function to prevent electrical shock.
For MODELS 335 & 340, the air filter is located next to the vacuum pump motor at the rear
of the unit. To gain access to the filter, remove the two Phillips head screws and the sheet
metal panel at the bottom rear of the unit. When finished, be sure to put the panel back and
tighten the two screws.
For MODELS 350, 355, & 370, the air filter is located outside the bottom front drawer, on
the right when standing in front of the unit. To open the drawer, loosen, but do not remove,
the Allen caps with a 3/16”Allen wrench.
REPLACEMENT GLASS
Replacement glass for under the blanket frame cannot be shipped from the factory. In the
event that the glass becomes either scratched or broken, contact your nearest glass
manufacturer and order the following.
Clear (i.e. free of imperfections like knots, etc.), Not Tempered, Polished Plate glass,
with Flat Ground edges and Dubbed corners, according to the respective dimensions.
