Please read the entire manual and fully understand the
proper operating procedures before proceeding to use
the press
.
1. Place the vacuum press in either a BIENFANG
®
Floor
Stand or a sturdy, flat, level surface and ensure the
feet and hinges are properly adjusted. The press should
not be located in the direct path of air conditioning or
room-cooling vents.
2. Keep the vent cloth positioned so that it covers the
vacuum manifolds (located in the rear corners of the
press) and does not extend across the edge of the
rubber diaphragm. Failure to do so will result in tempo-
rary loss of vacuum.
3. Place all materials inside the press so that they fit into
the recessed chamber in the base. If any materials
extend across the edge of the rubber diaphragm, they
will prevent a seal and cause either low vacuum or no
vacuum at all.
4. When opening and closing the press grasp both han-
dles and keep your body, head and hands away from
the press opening.
5. Foreign objects such as knives, tools, rulers, paper
clips and markers should be kept out of the press and
away from the press opening at all times.
6. Do not stack boards in the press. Placing a smaller
board on top of a larger one may cause lines or dents
in the aluminum platen.
7. Do not use an exposed blade to cut materials in the
press. A slice or puncture in the rubber diaphragm will
result in loss of vacuum.
8. Allow the vacuum level to drop before opening the
press.
9. Turn the power breaker OFF and keep the press in the
closed position when not in use. Disconnect the power
supply before cleaning or replacing parts.
10. High-pressure gas springs make opening and closing
the press easier. If they are to be removed, the top
MUST be held in the fully opened position for safety
and to prevent damage.
Contact your authorized Hunt dealer or Hunt Technical
Service in the event the press needs service for parts not
covered in this Owner’s Manual.
IMPORTANT SAFEGUARDS
The Bienfang
®
Vacuum Press 3648H, 4468H and 5298H
presses are professional mounting and laminating systems
designed to provide the highest quality results with maximum
versatility and ease of operation. The combination of two
machines in one – a dry mount press and cold vacuum frame –
allows the quick professional application of dry mounting adhe-
sives and laminates, as well as wet and spray adhesives. The
presses decrease labor costs and increase production while
minimizing operator training and supervision.
Specific features and benefits include:
• Easy to Use: Close the top, press a key and wait for the
signal that the work is done - automatic operation frees
the operator for other duties.
• Digital Display: lets the operator know at all times the
vacuum level, platen temperature and cycle time remain-
ing; the display is switchable between showing the original
settings and actual readings.
• Locking: All current models have side latches. Previous
models have the front latch.
• Programmable Settings: The operator can store up to six
programs in memory for repeatable processes. Time and
temperature settings for each program are stored for
quick, easy access.
• High, Uniform Vacuum Pressure: 10-13 psi (20-27" Hg)
ensures good bond penetration for consistent, professional
results.
• Automatic Pressure Adjustment: Self adjusts for boards up
to 1" thick, or mounts several pieces of varying thickness
at one time — without additional set-up time.
• Double-Duty Top: Specially constructed heavy-duty flat top
doubles as work or storage space when the press is not
in use.
• Floor Stand: Optional for 3648H and 4468H. Used to
make the presses freestanding units rather than tabletop
machines. Each incorporates one shelf support. The
5298H model comes with a floor stand.
