3.1Assemblyandinstallaon
1.Electricalinstallaon
Take the NL-24 Pro from its box and place it on a stable work bench, near an earthed wall socket. Connect
the machine with the supplied power cord to the electrical mains (230V alternang current). The NL-24 Pro
is earthed and provided with two fuses (4A T (slow).
2.Pneumacalinstallaon
It is very important that the NL-24 Pro is provided with clean, dry air.
The water condenser is an addional safety measure.
Provide air pressure of 2 - 6 bar from the compressor or its own local air supply.
Connect the air tubing with a diameter of 6 mm to the compressor or to your own local air supply, and to
the pressure regulator mounted on the back of the machine.
3. Foot switch
The NL-24 Pro has been issued with a foot switch. Connect the foot switch by pushing the connector into
the socket on the back of the machine. Secure the connecon by fastening the ring by hand.

4.Operanginstrucon
4.1OperangtheNL-24Pro
You can start operang the NL-24 Pro as soon as it is connected to both the electricity mains and to an airsupply
which provides clean and dry compressed air set at a maximum of 6 Bar. Switch on the machine by pressing the
on/o (I-0) switch, which is placed on the back of the machine, to “on (I)”. Wait unl the set temperature has
been reached, which will take about one minute.
Starngup:
At start up the display will show the Thermopatch logo.
The element is now heang up to the set temperature and the display will show informaon about the sengs.
Stand-by
When the machine is idle for a longer period than the set me for Stand-by, it will go into power saving mode.
The factory set me for Stand-by is set aer 15 minutes.
The heang element will be deacveted if this funcon is enabled. De fabrieksinstelling voor Stand-by staat op
15 minuten.
4.1.1 The control unit and display
The display of the control unit will show the version number of the rmware on display; this will dissapear
aer about 3 seconds and then it shows the last seng in which the machine was used. If any failures are
found at starng up, these will be shown in the display and the machine will not heat up.
See paragraph 4.4, page 8; the cause of the error code needs to be repaired rst.
The display will show the actual temperature and is ready for use.

5. Overview of safety measures and warnings
5.1 Safety
De NL-24 Pro is ed with all required safety measures to ensure safe working as required by European
safety guidelines.
The safety frame
The heang platen of the NL-24 Pro is protected by a safety frame. When this frame is touched the
machine will interrupt the work cycle and open up immediately. In order to resume work switch o the
machine and switch it on again.
Theemergencystopbuon
In accordance to the safety measures required by the conformity with the Machinery Direcve, an
emergency stop buon has been installed, to be able to intervene with producon in case of unforeseen
events. See chapter 4, paragraph 4.2.
Warning symbols
For enhanced security following warning symols are mounted on the machine:
WARNING!

Always turn the power off (unplug it) when you need to carry out maintenance work or when cleaning
the machine.
ATTENTION!
In case of emergency, press the emergency stop button!
ATTENTION!
Take care that there is enough space around the machine. Cables and connections must not get
pinched. Although the heat radiation of the press is low, there should be enough
space for cooling down.
ATTENTION!
Avoid contact with the press and the heating element.
ATTENTION!
Pull the fabrics tight around the lower platenn and ensure that your hands are away from
the machine before operating the machine.

8. Maintenance
Before starng any maintenance or repairs, make sure that the machine has nished its work cycle.
Depending on the planned job you want to perform both the air - and electrical supply can be
disconnected.
The air cylinder and other parts of the machine are maintenance free and the bearings are self lubricang.
The precondion for a good working performance is the supply of dry and clean compressed air.
The mounted water condenser and pressure regulator is an added safety feature. Moisture and unclean air
disrupt the self lubricang properes of the air cylinder.
Arrange for your maintenance to be performed by qualied sta or a maintenance service.
Temperature:
The temperature of the heang platen can be tested regularly by using temperature indicator strips. These
can be obtained through your Thermopatch supplier.
Teoncover:
The teon sheet that protects the element has to be cleaned regularly to prevent scking of labels and
patches or transfer of dirt to the garments. Clean the teon cover with a dry and clean cloth when the
machine is sll warm. Repeat the procedure regularly as oen as is necessary. Damaged or soiled teon
protecon should be replaced. These can be obtained through your Thermopatch supplier.
Sealingpad:
Clean the sealing pad while sll warm, with a clean lint free piece of cloth. Clean it as oen as is necessary.
Damaged or soiled sealing pads have to be replaced. These can be obtained through your Thermopatch
supplier.
Replacement of the teon protecon and the sealing pad:
The teon protecon sheet and the silicone rubber sealing pad have to replaced regularly. At replacing
these consumable parts the machine should be cooled down suciently to avoid burns from the heang
platenn.
Remove the teon protecon cover like a band aid when the platenn is sll warm to the touch. Remove any
glue residue from the hean element carfully. When placing the new self adhesive teon ensure a smoot
and clean surface in order to have a bubble free adhesion.
The sealing pad can easily be worked loose with a screwdriver aer which the replacement sealing pad can
be clicked into place on the mounng platen.
Both the teon cover and the sealing pad are available through your Thermopatch supplier.
WARNING!
The supplied pressure should not be higher than a maximum of 6 bar
WARNING!
Remove the plug from the wall socket before starting loosening any screws and housing parts

Airlterpressureregulator:
The air lter pressure regulator (1) has to be checked daily and be cleaned by turning the plasc nut
underneath to open.
Replacing the fuses
Ensure that the NL-24 Pro is disconnected from the electrical supply and the plug is unplugged from the
wall socket. Replace the fuses 4 A (slow) (2) by taking them from the power entry which is mounted on
the back of the machine. Before reconnecng the plug into the wall socket, make sure the power entry
shows the right voltage seng (230V). If the wrong seng is shown, remove the fuse holder, turn it 180°
and insert it back in again. Aer the fuses have been replaced the machine can be reconnected to the wall
socket and switched on again.
ATTENTION!
Please ensure that the right voltage annotation is shown before powering the machine
ATTENTION!
Flip open for access to the fuse holder
make sure the power entry shows the right voltage setting reconnecting the machine!
