OVERVIEW
This heat press has been designed to operate at high output without risk to operator safety in accordance with
article L 233-5 of the French labour code.
It has been designed for use by a single operator positioned in front of the machine.
OPERATION
Please read the Operating Manual carefully before operating the press.
The press should be operated by a qualified person who is aware of the potential dangers arising from improper
use of the equipment.
The factory-installed pneumatic, electrical and mechanical settings programmed by our technicians and the safety
features must not be altered under any circumstances. SEFA accepts no liability for problems that may be caused
by the machine if such alterations are made.

1. SAFETY
THIS MACHINE IS DESIGNED FOR USE BY A SINGLE OPERATOR
FOR USE BY QUALIFIED PERSONNEL
a) International symbols
b) Important safety precautions
Personal protective equipment should be worn (e.g. safety gloves and glasses).
Do not touch hot parts of the machine during use.
Do not place hands between the platens when the machine is switched on.
Make sure the operator is not exposed to risks of burns, electrocution or other hazards when handling the
machine.
Check the machine each day before use.
Make sure there is nobody in the vicinity of the machine before starting work.
If the machine malfunctions, cut the power supply and look for the cause of the problem (see the Servicing
section).
c) Safety features
No changes must be made to the safety covers and safety systems.
They must be refitted if they are removed for servicing work.
They must be held securely in place and kept in good condition during normal use.
DUPLEX PRO presses are fitted with safety systems to protect the operator from pinch-point hazards.
The main safety components are:
Emergency stop button
Front-mounted button that switches the machine off when pressed.
Safety cover
Two contact switches are located on top of the upper heat platen.
This system helps safeguard the operator against pinch points and crushing hazards.
If the system detects an obstacle, it raises the heat platen, immediately shuts off the swing function and puts the
press into safe mode.
To restore the machine to operating mode, press the RESET button, position the swing arm over one of the lower
platens and depress the foot pedal.

5 .OPERATING CYCLE
Move the swing arm away to the opposite side from the platen you want to work on.
Depress the foot pedal to confirm your selection.
Place the work item on the lower platen.
Position the transfer sheet correctly.
Depress the cycle start foot pedal.
The swing arm will move into place over the platen, the heat platen will lower and the press timer will
start.
Use this time to prepare the next work item and transfer sheet on the second workstation.
The heat platen will lift open when the timer has finished.
Depress the foot pedal if the machine is not in “FULL AUTO” mode.
If the machine is operating in Full Auto mode, the platen will swing away automatically after it has lifted clear and
the post-press timer has finished its countdown.
Remove the work item from the first workstation and get the next one ready.
Repeat from step three above.
Depressing the foot pedal during a cycle will stop the cycle and move the swing arm to the other side.

7. FULL-AUTO MODE (OPTIONAL)
a) Cycle options: "foot pedal", "single workstation" and "full auto"
DUPLEX PRO has 3 cycle options:
Foot-pedal mode: depressing the foot pedal causes the arm to move to the other platen and press.
Single-station mode: depressing the foot pedal causes the arm to move to the other platen, press and then
return to the original platen.
Automatic mode: depressing the foot pedal causes the arm to move to the other platen and press. When
the "post-press timer" has finished, the arm automatically returns to the other platen and presses again. This is
repeated until the operator stops the automatic cycle by pressing the STOP icon or depressing the foot pedal.

SERVICING
TO BE PERFORMED BY QUALIFIED PERSONNEL
THE MACHINE MUST BE SWITCHED OFF AND LOCKED AND TAGGED
PRIOR TO SERVICING
(ELECTRIC AND PNEUMATIC POWER SOURCES DISCONNECTED)
The following tools should be available at hand:
Phillips and flat-blade screwdrivers
Set of open-ended spanners and box spanners
Set of Allen keys
Multimeter
1. REPLACING WORN PARTS
a) Silicone foam pads
Check that the platen is cold.
Make sure the surface of the platen is clean.
The surface can be cleaned using a mild solvent such as isopropyl alcohol. Suitable personal protective equipment
must be worn.
Use RTV-1 glue to stick the foam pad to the aluminium platen (NB: read the instructions for use on the packet).
The pad and the platen must be clean and dry before they are stuck together.
Apply a thin layer of glue evenly over the platen and then stick the pad immediately into place, making sure there
are no air bubbles trapped between the platen and the pad (NB: a notched adhesive comb of the type used for
floor tiling would be suitable).
Leave to set overnight at room temperature with a slight pressure applied and the platen cold.
b) Other parts
Contact your stockist to determine whether they need to be renewed or repaired.
2. Maintenance
SEFA heat presses are practically maintenance-free. Follow the preventive maintenance instructions below to
ensure trouble-free operation:
Do not heat items that could perish or score the silicone pad or damage the heat platen’s teflon coating.
Clean the machine at regular intervals, with the platen cold, using a clean cloth and isopropyl alcohol (NB:
isopropyl alcohol is flammable - use with care and keep away from sources of heat) and wearing suitable personal
protective equipment.
Keep the heat platen in the raised position when it is hot but not in use.
DAILY CARE:
Clean the foam pad and the platen’s coating (when cold) with a dry cloth or a dry cloth and grease
remover.
Inspect the air inlet filter on the left side of the swing arm; drain the filter if it is heavily condensated.
MONTHLY CARE:
Check that the hinged joints are lubricated.
According to use:
Replace the foam pad every 6 months.
