Glass
Top Vacuum Press.
The Hot Press Glass Top Vacuum Press incorporates a
proven, high technology heating system. The top panel
of the press is made up of two sheets of reinforced
tempered glass. The inner surface of the lower sheet has
a transparent conductive coating applied to it. A controlled
electric current is passed through this conductive fi lm
creating a highly effi cient heating system. A sensor
on the glass monitors and controls the temperature
by means of a digital thermostat. The transparent top
offers a high level of operator confi dence as work can be
viewed throughout most bonding processes. The glass
is extremely smooth and scratch resistant.
The Hot Press Glass Top Press handles a wide range of presentation
materials from foam board and wood to photos, art prints and delicate
fabrics. The Hot Press brand is well regarded by picture framers and
other fi nishing professionals for its ability to produce consistent, high
quality results.
All models feature an electronic timer with a manual override switch
and vacuum pressure adjustment capabilities. Upon completion of the
cycle, vacuum pressure is automatically released and the timer resets
itself.
To ensure operator safety and to achieve the best results from your
Glass Top Vacuum Press, the machine must be set up and operated
in accordance with the instructions in this manual. Please review the
entire manual before using the press for the fi rst time.
We maintain a policy of constant improvement to our products. This
means that you may fi nd that some illustrations and descriptions will
vary from the equipment you are using.
If you have questions concerning applications of the Glass Top
Vacuum Press, please give us a call. Expert assistance is available at
no charge. We can also supply many of the adhesives, overlaminates
and other materials used in conjunction with this equipment. For more
information, please contact our Customer Service Department (see

Safety Considerations
This product should only be used for the purpose and manner for
which it was designed. Before installing and using the equipment,
please read this entire manual and be sure that you understand
all the aspects of proper use. Some of the more important safety
considerations are listed below.
• Ideally, the vacuum press should be used with a metal stand
(available from Drytac). If a stand is not used, the press
must be located on a sturdy table or countertop capable of
supporting its weight (refer to Technical Specifi cations on page
17 of this manual). The largest model (HGP560) is supplied
with a stand, which must be used due to the weight of the unit.
• Connection of the equipment to the power source must be
handled by a qualifi ed electrician familiar with local and
national electrical codes. It is mandatory that the equipment be
properly grounded.
• The gas struts which support the lid are a critical safety item.
They must be fully extended (in other words, the lid must be
open completely) in order for them to support the weight of the
lid. The press must be installed in a location which allows the
lid to be completely raised without interference. If the lid is only
partially opened, it may close unexpectedly.
• Before each use, the struts should be checked to be sure they
are operating properly. Over a period of time, the struts will
lose pressure and will eventually require replacement.
• The inner surface of the glass top is very hot during normal
operation. Be very careful not to touch the glass when
inserting or removing materials from the press.
• Before servicing the equipment, it must be disconnected from
the power source.
• If either of the circuit breakers on the rear panel of the unit
should trip repeatedly, unplug the equipment and have it
serviced. The same applies to the fuses on the side panel.
• The vacuum press incorporates a high-temperature safety
cutout device, which disconnects all power from the unit if the
internal temperature reaches a predetermined level (257°F
/ 125°C). If the unit unexpectedly shuts off during use and
later comes back on after cooling down, it is likely that this
safety device has activated. This indicates a problem with the
temperature control system, and the unit should be repaired by
a qualifi ed technician.
• Do not use a knife to cut materials while they are inside the
press. This could cause damage to the diaphragm.

SETTING UP YOUR NEW VACCUM PRESS
Equipment Location:
The smaller vacuum press models
such as the HGP220 and HGP260 may be used on a
table or countertop, provided that it is able to support
the weight of the equipment. The larger models should
be used with a fl oor stand due to their size and weight.
The ideal working height of the press will vary depending
on the operator. We suggest a height of 28 to 31 inches
(700 to 790 mm). It is critical that the lid of the press is
able to open fully. Please be absolutely sure that nothing
interferes with this!
For proper operation, it is very important that the press
be fl at and level. The best way to verify this is to use a
carpenter’s (bubble) level. If one corner of the unit is at a
different height from the others, it may be diffi cult to achieve
a proper vacuum. For best results, we recommend that
the press be located away from air conditioning vents,
fans and other sources of moving air.
Unpacking:
Carefully inspect the vacuum press for possible shipping
damage. If any is discovered, please contact our Customer Service
Department immediately. If you are using a fl oor stand, unpack and
assemble it using the instructions provided. Remove the vacuum press
from the shipping carton and place it on the stand or table. Leave room
to make connections to the rear of the unit.
Unpack and remove the vacuum pump from its box. The pump
should be placed on or near the fl oor. There are suction cups
on the bottom of the pump to help keep it in place, since the
pump vibrates during operation. The pump will become warm
during extended usage. If the equipment is going to be used in a
high-volume production environment, please allow for adequate
ventilation of the area where the pump is located.
Stand Assembly (Model HPG560 Only)
Loosely fi t the four tie bars to the ends of the stand (Illustration
4B), using the 16 M10 x 50 bolts, 32 x M10 plain washers and 16
M10 nuts. Tighten all nuts and bolts. Move stand into fi nal position
and ensure that it is level by using the leveling spacers. The stand
may be leveled by supporting the low corner of the stand on the
tie bar and removing the wheel. The leveling spacers can then
be inserted between the stand and the wheel assembly and the
wheel assembly re-bolted to the stand. Lower the stand back to
the ground and re-check to make sure it is level.
Mount The Press Onto the Stand
(Model HPG560 Only)
Remove the divider panels from the crate. Remove the screws
from the side pieces of crate. Remove protective packaging from
the press. HOLDING THE FRONT AND REAR OF THE PRESS
ONLY AND NOT WITHIN 75 mm OR 3 INCHES OF THE ENDS, lift the
press from the crate onto the stand. Align the press with the ends of the

at front of diaphragm and draw diaphragm forward by approximately
300 mm or 12 inches. Working on underside of diaphragm, remove
hoses from fi ttings on diaphragm by pushing collar on hose end of fi tting
inwards and pulling out hose. Remove diaphragm from press. Using the
4 M6 x 80 mm bolts, 8 M6 penny washers, 4 M6 spring washers and 4
M6 nuts, secure the press to the stand by passing the bolts up through
the holes in the stand ends and into the base of the press. Tighten these
nuts and bolts. Insert the diaphragm back into the press and unsert the
hoses back into the fi ttings on the underside of the diaphragm.
Push the diaphragm back into position ensuring it fi ts into the three
clips at the back of the press and re-fi t the three screws at the front of
the diaphragm.

Connecting the Vacuum Pump
A length of plastic vacuum tubing (either red or green, depending on
the model) is supplied with the equipment. Connect one end to the
pump and the other end to the rear of the vacuum press. No tools are
needed - the tubing is a simple “push fi t” into the special connectors.
You will feel two stages of resistance as the tube is inserted. The ends
of the tubing must be clean and smooth to ensure a good seal. If
damaged, simply cut off 1/4” (5mm) with a sharp knife. To remove the
tubing, press the end of the metal fi tting and pull the tubing out.
Plug the electrical cord from the pump into the matching connector on
the rear of the vacuum press.

Electrical
ELECTRICAL CONNECTION
All four models of the Drytac Glass Top Vacuum Press require single-
phase AC power. The current and power requirements are different for
each model, and are summarized below.
Please be sure to provide adequate ventilation if the equipment is to be
used in a high-volume production environment.
Make certain that the power source conforms to the requirements
specifi ed above. All local electrical and safety codes, as well as the
current National Electrical Code (NEC) must be followed. All wiring
must be installed by a qualifi ed electrician.
To reduce the risk of electrical shock, the vacuum press must be used
only with a properly installed 3-wire grounding-type receptacle and
plug combination. Do not use extension cords or 2-prong adapters with
this equipment. Proper grounding of the receptacle must be verifi ed
before use.
The electrical cord should be routed and secured so that it does not
present a hazard. Protect the cord at all times from sharp objects, hot
surfaces, oil and chemicals. Avoid kinking the cord. Periodically inspect
the cord and plug, and replace immediately if worn or damaged.
Disconnect the equipment from the power source before moving or
servicing.
Test the GFCI (Ground Fault Circuit Interrupter) circuit breaker. It
is the circuit breaker located nearest to the center of the rear panel
of the press. It should be tested after installation (and periodically
thereafter) to ensure that it is functioning correctly. To test it, press the
test button (labeled “T”) adjacent to the breaker handle. The breaker
should immediately trip. If it does not, the GFCI is defective and must
be replaced. Note that the equipment must be connected to a power
source in order to perform this test.

PRINCIPLES OF OPERATION
Your Hot Press Glass Top Vacuum Press is precision
engineered to deliver the optimum heat and pressure for
a variety of mounting and overlaminating applications. A
conductive coating is applied to the upper surface of the
lower of two sheets of tempered glass that form the lid
of the press. When an electrical current is applied to the
coating, the glass heats up in a very even and consistent
manner.
When the lid is closed onto the gasket around the
outside of the bottom frame, it forms an airtight chamber
from which air is drawn out by the vacuum pump. The
vacuum causes the fl exible diaphragm in the base, and
any materials placed on it, to be pressed against the
glass, thus applying the heat and pressure needed to
bond materials together.
Key Processing Factors:
There are three key processing settings that apply to virtually all
mounting and laminating jobs.
• Temperature
• Time (Dwell)
• Pressure
Temperature:
The temperature setting is primarily dictated by the
requirements of the heat-activated adhesives used in the dry mounting
tissue and the overlaminating fi lm recommended for your job. It is
important that the press be operated at the correct temperature to
activate the adhesive and bond the materials. See page 8 for more on
temperature controls.
Time (Dwell):
This factor works in conjunction with temperature to create
a permanent bond between materials. Assuming that the temperature
setting of the press is suffi cient to activate the adhesive, it is almost
always preferable to increase dwell rather than temperature. Dwell time
is set using the Timer (page 9) and dictates the vacuum cycle (see
Pressure, below).
Pressure:
Pressure is established in the press by the vacuum pump,
which is controlled by the Timer (see page 9). The vacuum presses
the materials together for the amount of time chosen by the operator
using the timer controls. Pressure should usually be set at over 25” of
mercury. It should be reduced for softer mounting materials such as
foam board using the vacuum adjustment valve.
Other Factors
Following the recommended temperature and time settings on your
Glass Top Vacuum Press will almost always produce excellent results.
However, other factors can affect the settings on the machine.
Materials
: Manufacturer’s dwell and termperature settings are based on
paper graphics. However, heavier materials such as canvas absorb more
heat and may require a higher temperature setting or longer dwell time
setting. This is also true for denser or thicker mounting substrates.
Workpiece size:
The same principle applies to the overall size of the
job. Larger jobs absorb more heat and may require longer dwell times.
Controls
NOTE:
Whenever possible, test actual
materials together prior to processing a
challenging or unusual job.

FUNDAMENTALS OF DRYMOUNTING
Dry mounting an image to a substrate can be performed in a variety
of ways and varies according to the nature of the mounting substrate,
mounting adhesive and the print, photo or artwork being mounted.
However, the basic methods described below will provide excellent
results for most standard applications.
1. Set the vacuum press to reach an operating temperature of
185°F (85°C)*.
2. Cut a piece of dry mounting tissue slightly larger (on all sides)
than the work to be mounted.
3. Place your print face down onto a clean work surface and
cover with the dry mounting tissue. Lightly tack the tissue to the
back of the print with a tacking iron. To avoid adhesive build-
up on the tacking iron, tack through silicone release paper/fi lm,
shiny side toward the tissue. Trim the excess tissue.
4. Place the print, with the tissue attached, onto the mounting
substrate. Lift the opposite end of the print/mounting tissue
and tack the mounting tissue side directly onto the mounting
substrate.
5. Place the three components into the press between two
sheets of release paper/fi lm for approximately 30 seconds to
3 minutes*– from the time the press has achieved the desired
pressure setting.
* Your actual settings will vary according to the size of the press, type
of dry mounting tissue, the type of mounting substrate, the artwork
material used (in terms of material and the size of the print). See
individual product specifi cations for recommended dwell times.
PROCESSING TIPS:
• Maximum vacuum pressure is
recommended - except when
mounting onto foam board, as this
type of substrate may be subject
to “crushing”. When mounting
onto foam board, we recommend
using reduced vacuum pressure
during the mounting cycle.
• We recommend silicone coated
clear release fi lm over silicone
release paper. Clear release fi lm
is transparent (allowing you to
see the work in progress), less
prone to “creasing” and has a
longer usage life.
• The diagram in Illustration 11A
shows the positioning for each
component in the dry mount
package prior to being placed in
the press.
Note:
Clear release fi lm or silicone release paper must be placed on
top of the “mounting package” to prevent any exposed adhesive from
sticking to the glass.

Laminating
FUNDAMENTALS OF LAMINATING
Laminating is the process of applying a thin clear fi lm to the surface
of a print, photograph or other type of graphic. Drytac manufactures
a wide range of Artshield
TM
laminate fi lms for use with the Hot Press.
TM laminate fi lms for use with the Hot Press. TM
The materials are activated by temperatures in the 185°F–210°F
(85°C–99°C) range, with processing times ranging from 2 - 10
minutes. Please check the specifi c product recommendations before
laminating.
1. Cut a piece of ArtShield™ UV HeatSet laminating fi lm (or
other appropriate heat activated laminating fi lm) approximately
1⁄2” (1cm) larger (on all sides) than the print to be laminated. At
this stage, your print may already be mounted or, if you choose,
you may dry mount at a later time without affecting the laminated
fi nish (refer to step 8 below).
2. If the print/graphic to be laminated has a non-breathable
surface such as a resin coated (RC) photograph, it will be
necessary to use a pre-perforated ArtShield laminating fi lm. If
the selected fi lm is not pre-perforated, place it onto a cutting mat
or card stock with the fi lm surface face up. Using a perforating
tool, lightly pierce the fi lm in a crisscross pattern; ensuring the
holes are approximately 1/4” (6mm) apart.
3. A release paper backing protects the adhesive-
coated side of the laminating fi lm. Peel this back
approximately 1” (2.5cm), exposing one edge of
the laminating fi lm. Place your print face up on
a clean work surface. Position your laminate on
top, exposed adhesive edge down. While holding
it fi rmly on the table with one hand, gently pull
the release paper away and toward you from
underneath.
4. Check that there is no dirt or dust trapped under
the laminating fi lm. If necessary, the fi lm may be
gently lifted, the contaminants removed and the
fi lm repositioned.
5. Using a burnishing pad or soft cloth, lightly
smooth the laminating fi lm down onto the print to remove excess
air bubbles.
6. Place the print onto a larger piece of silicone release paper/
fi lm shiny side up.
7. Preheat your press to 180 - 210ºF (82 - 99ºC)*.
8. Cover your work with the foam overlay blanket and place into
the press.
9. Your work piece should be processed for two to ten minutes* -
beginning from the time that the press has achieved the desired
pressure setting.
10. The fi nal result should be a blemish-free fi nish. If any silvering
is apparent under the clear fi lm (especially visible in the dark
areas), re-insert and process for an additional 2-10 minutes*.
Caution:
ArtShield™ Glossy laminating fi lm cannot be pierced and is
not recommended for photographs.
* Your actual settings will vary according to
the size of the press, type of dry mounting
tissue, the type of mounting substrate, the
artwork material used (in terms of material)
and the size of the print. See specifi c
product specifi cations for recommended
dwell times (dwell times provided are for
paper graphics).
Note:
Put the foam overlay blanket directly
on top of laminating fi lm. Do not put release
paper/fi lm between fi lm and foam overlay
blanket or between foam overlay
blanket and top of press.

Mounting
P
REPARING YOUR MOUNTING SUBSTRATE
Once you have decided on the most appropriate adhesive/substrate
combination for your application, it is important that you properly
prepare your substrate before coating. Although often overlooked, this
can be the most important step when mounting a print or artwork for
display.
FOAM BOARDS
(E.G. FOME-COR®, ETC.)
The surface of these types of substrates is porous and often contains
particles that can spoil an otherwise perfect mount. Clay-coated
surfaces such as Fome-Cor®, Foam-X® and similar boards should
simply be wiped with a TacCloth™ to remove dust particles.
MAT BOARDS/MILL BOARDS
To prepare mat board or millboard for mounting, use the Anti-Static
Wisk™ brush to remove dust particles and other debris.
HARDBOARD
(E.G. MEDIUM DENSITY FIBERBOARD, MASONITE, ETC.)
To prepare hardboard substrates for mounting, wipe down the
surface with a TacCloth. Should the surface contain irregularities, use
sandpaper to remove them, then wipe the surface with a TacCloth.
Please note:
Due to their highly absorbent properties, do not wipe
down the surfaces of any of these substrates (i.e. foam board, mat/
millboard or hardboard) with a moist rag.
Tip:
It is important that you remove dust
and other debris from your prints prior to
mounting.

Each day before using the press, check the pump fi lter bowl
for water. To drain the bowl, ensure the pump is turned off, then simply
unscrew the bowl, dump the water out and re-attach the bowl. If the
press is used for mounting on foam board, the water trap may have
to be emptied quite frequently. Do not allow the bowl to become full,
as this may allow water to enter the vacuum pump and cause serious
damage.
Use a brush or vacuum to remove dust and debris from the rubber
diaphragm as needed. Keeping the diaphragm clean will help prevent
the pump fi lter from becoming blocked.
Clean all the way around the grey silicone seal with a damp cloth,
checking for foreign matter and cuts.
If any adhesive has accumulated on the glass, it may be dissolved
with acetone or nail polish remover. Do not use abrasive cleaners.
A single-edged razor blade may also be used, but be careful not to
scratch the glass.
The outside of the press may be cleaned with any standard, non-
abrasive household cleaner.
Latch Adjustment:
The latches on the front of the unit should close
easily with a comfortable “click”. If they are too loose or if they
need excessive pressure to close, they can be adjusted by turning
the latch on the pivoting, threaded shaft. Adjust only one turn at a
time. Lengthening the amount of threaded shaft visible (by turning
counterclockwise) will tighten the latch and shortening the amount (by
turning clockwise) will loosen it.
Overtightening the latches will not improve the effectiveness of the
vacuum seal and will cause the latches to wear out prematurely.
Hinge Adjustment:
The hinges at the rear of the press are designed
so that they can be easily adjusted to ensure a good vacuum seal.
Make sure that both hinges are adjusted by the same amount to keep
the press lid level.
The top part of the hinge is bolted to the top frame and cannot be
moved. Adjustment is carried out on the bottom part of the hinge. Both
bolts pass through elongated holes in the frame. Should it become
apparent that the grey sealing gasket is not in contact with the
underside of the lid across the entire back of the press, the adjustment
procedure is as follows:
Close the press; loosen both Bolts “A” half of a turn. Turn on the
vacuum pump. Using a wrench, turn Bolt “B” on each hinge a little at a
time until a vacuum is pulled. Only a small adjustment will be required.
Re-tighten both Bolts “A”.
Vacuum Pump:
The vacuum pump is built with sealed, permanently
lubricated bearings and does not require lubrication or other periodic
maintenance other than cleaning the fi lter & water trap.

VACUUM TROUBLESHOOTING
The vacuum gauge should indicate approximately 25” of
mercury during normal operation. If the reading is too low, or
the press takes a long time to “pull a vacuum”, check for one
or more of the following common problems:
1. Foam or other materials trapped in the seal:
It is very
easy for the foam overlay blanket to become misplaced and
inadvertently become trapped in the seal. This will allow air
to leak in, preventing a good vacuum from forming. Foam
used in the press will tend to expand over time. As this
happens, you should lay it on the bench and trim a strip off
each edge. Also check for paper, canvas or other materials
that may be stuck to the lid and interfering with the seal.
2. Press is not level:
If all four corners of the press are not
level, it may be diffi cult to achieve a proper vacuum. Use
a carpenter’s (bubble) level to verify. If one corner is out
of alignment, use shims under the press as necessary to
correct.
3. Misalignment of press lid:
To verify this, do the “bookmark” test.
Cut thin strips of paper and place at different sections of the seal all the
way around the press. Close the lid and secure the latches, then try
to remove the paper strips. The paper will normally be held tight. If the
paper can be pulled out, this will indicate there is a gap between the
seal and the lid of the press.
Normally, this can be resolved by adjustment of the hinges at the rear
of the press. Refer to the Routine Maintenance section on page 14 for
the procedure.
A gap at the front of the press may also indicate that the latches need to
be adjusted. The latches should snap shut with a fi rm “click” but should
not be diffi cult to close. If they are too loose, follow the adjustment
procedure in the maintenance section. Do not overtighten the latches,
as this will cause them to wear out prematurely and will not improve
the vacuum.
4. Diaphragm has split or has been cut
: Inspect the diaphragm
carefully for holes, particularly around the edges and in the corners.
Small holes can be repaired with a bicycle tube repair kit. (Apply the
patch to the bottom of the diaphragm.) If necessary, the diaphragm can
be removed from the press for inspection. Be sure to disconnect the
press from the power source before taking the diaphragm out.
5. Internal vacuum leakage:
Put your thumb over the hole in the rear
corner of the diaphragm and observe the reading on the vacuum gauge.
If the reading is still too low, check the following:
a. Check that all vacuum hose connections are tight.
b. Check the pump fi lter for blockage. Ensure the pump is off, then
unscrew the fi lter bowl, pull the fi lter cartridge out and refi t the bowl. If
this fi xes the problem, the fi lter element will need cleaning. Unscrew
the retaining plate at the bottom of the cartridge and withdraw the fi lter
element, wash in household detergent and re-assemble.
Note:
The HPG560 has two vacuum inlets, one in each corner.

ELECTRICAL TROUBLESHOOTING
1. Press shows no readings on temperature or timer controls
• Check the two circuit breakers on the rear panel of the unit. The
levers should both be pointing to the right (as seen from the back).
Some models have circuit breakers with a color code – green indicates
off, and red indicates the on position.
• Check power source – verify that the power cord is fi rmly connected,
and that the power outlet is live. If it is not, check the circuit breaker at
the building’s electrical distribution panel.
• Unplug the power cord and check the fuses on the left side of the
unit.
2. Press starts up normally, then overheats and shuts off, or the
temperature controller displays an error code such as “PFA” or
“LOR”.
• There is a problem with the temperature controller or temperature
sensor. Contact Drytac for assistance with repairs.
3. Vacuum pump does not operate in either automatic or manual
mode.
• Electrical cable from pump to rear panel of vacuum press is
disconnected.
• Pump fuse (on left side panel has blown). Unplug the power cord
and check the fuse.
• Vacuum pump has failed.
