Description of the machine
The Shannon HRT line heater is a rapidly convertible
machine for the production of large series of items with
multiple bends for the plastic sheet processing industry.
The machine has two adjustable heating elements as
standard. The temperature of which can be adjusted
independently by electronic controls.
The filaments of the heating elements on the working
surface are adjustable in height.
The workpiece can be heated from one side and it is
possible to bend sheet up to 8 mm thick.
The working surface is made of scratch-resistant solid
core material with which the space between the zones to
be heated can be filled to support the plastic sheet.
When heated, thermoplastics become so flexible that they
can be shaped. When a plastic sheet is heated to its
softening point in a narrow zone, if can be bent to any angle
desired.
The bending radius is determined by the width of the heated
zone. The zone is determined by the thickness of the
material, the type of heating element and the distance
between the plastic and the filament.
Every plastic has its specific softening point. By co-
ordinating the temperature, heated zone and heating time all
kinds of thermoplastic can be processed.

Safety instructions
SAFETY INSTRUCTIONS:
To ensure safety when using the machine you should read
this User's Guide carefully and follow the safety instructions
closely.
Attention!
The machine contains parts which are hot. Touching
them will cause burns.
Allow hot parts to cool sufficiently (at least 10 minutes)
before touching them.
Never touch the filaments or the reflectors when the
machine is in operation.
Always wear close-fitting clothing.
Be particularly careful of sleeves and always tie back long
hair.
Never leave objects on the working surface.
The machine may only be used for heating narrow
zones in flat plastic sheet.
Any other use could lead to very hazardous situations or
cause damage to the machine!
Before commissioning and servicing always check the
connection cable and plug for defects.
When servicing switch off the machine and remove the
plug from the socket.
Only switch on those heating elements which are
needed.
Never leave the machine unattended without switching
it off.

Installation
5.1 ASSEMBLY
1. Place the machine on a level floor with sufficient space
around and above the machine.
2. Ensure there is adequate ventilation and lighting at the
workplace.
3. Avoid draughts, in order to prevent uneven heating.
5.2 CONNECTING MAINS VOLTAGE
1. Check that all control units are in position O(switch H).
2. Plug in the machine.

Operation
6.1 PREPARATION
1. Clear the working surface.
2. Check that all the heating elements are connected to
the control units.
3. Check that no scraps of material remain in the
reflectors.
6.2 SWITCHING ON HEATING ELEMENTS
Each heating element can be switched on and
controlled individually.
1. Switch on control unit with switch H.
6.3 SETTING TEMPERATURE
The temperature of the filament can be set using the
temperature control.
1.When turning on the on/off switch, the display will show
the value that was last saved (keeping the machine on a
certain value for >20 seconds will make it remember this
value).
2.Press the right button (arrow up) to increase the value, up
to 99 (keeping this pressed in will make the value cycle
much faster)
3.Press the left button (arrow down) to decrease the value,
down to 00 (keeping this pressed in will make the value
cycle much faster)
4.Press both buttons at the same time to go directly to 00.
Doing this also resets the machine.

Adjustment
7.1 SAFETY PRECAUTIONS
Always take the following safety precautions before adjusting
the heating elements:
1. Switch off the heating elements one at a time (Switch H).
2. Clear the working surface.
3. Allow the heating elements to cool for at least 10
minutes.
7.2 HEATING ELEMENT
1. Remove the strips of solid core material next to the
heating element to be adjusted by loosening the two
socket head screws. (Use socket screw key no. 5).
2. Loosen the socket head screws in the supporting prongs
on the left and right of the heating element one half turn.

3. Loosen the socket head screw in the centre of the
heating element one half turn. (Use socket screw key no.

4. Take the heating element with both hands close to the
supporting prongs on the left and right and slide it into the
desired position. Hold the heating element parallel to the
front of the machine and the supporting prongs. This
prevents the notched nuts in the X-profiles from binding.
5. Hand tighten the socket head screws, starting in the
supporting prongs and then in the centre.
6. Position the other profiles in the same way if necessary.
7. Fill up the space between the heating elements as far as
possible with solid core strips and hand tighten them.
First slide the notched nuts into the aluminium X-profile
roughly level with the holes and then lay the solid core
strip on top.
8. Switch on the machine again as in Section 6.
7.3 FILAMENT HEIGHT
1. Adjust the height of the filament using the knurled nut.
These can be reached from the sides. Make sure that
the filament height is the same on both sides.
2. Start up the machine again as in Section 6.

7.4 STOP
1. Loosen both the handles on the stop one half turn.
2. Slide the stop into the desired position.
Hold the guide parallel to the front of the machine. This stops the
clamping blocks from binding.
3. Tighten the handles.
4. Pull the handle upwards against the spring pressure and
turn it outwards.

Tensioning and changing filament
9.1 SAFETY PRECAUTIONS
Before tensioning and changing the filament always take the following safety
precautions:
1. Clear the working surface.
2. Switch off the control units one at a
time (switch H).
3. Allow the heating elements to cool
for at least 10 minutes.
9.2 TENSIONING
1. Turn the filament to the lowest position.
2. Hold the end of the wire on the right with pliers and undo screw in the
wire pin.
(Use socket screw key no. 2)
3. Pull the wire taut with pliers and tension the spring.
4. Tighten the socket head screw firmly again.
5. Cut off the end of the filament. Always leave 8-10 mm
projecting in order to be able to tension the filament again. Bend the
projecting piece down.
Attention! The end of the filament is sharp.
