5. INSTALLATION
WARNING! CARRY OUT ALL INSTALLATION AND ELECTRIC
CONNECTION OPERATIONS WITH THE MACHINE SWITCHED OFF AND
DISCONNECTED FROM THE MAINS.
THE ELECTRIC CONNECTIONS MUST ONLY BE CARRIED OUT BY EXPERT OR
QUALIFIED TECHNICIANS.
5.1 HEATING SYSTEM POSITION
Identify the place where the heating machine is to be installed so that there are no
obstacles that block the cooling air entry and exit vents; make sure at the same time
that conductive powder, corrosive vapours, humidity, etc. are not being sucked in.
Keep at least 250mm of free space around the machine.
WARNING! Position the heating machine on a flat surface or
trolley that is suitable for supporting the weight to avoid machine toppling or
dangerous movements.
5.2 CONNECTION TO THE MAIN POWER SUPPLY
Warnings
- Before carrying out any electrical connection, make sure the rating plate data on the
machine to make sure they correspond to the voltage and frequency of the electric
network available in the installation place.
- The machine must only be connected to a power supply system with neutral
conductor connected to earth.
5.2.1 Plug and socket
The machine is supplied from the factory with a power supply cable fitted with a
standard plug (2P + T) 16A/250V
It can therefore be connected to a mains socket fitted with fuses or automatic circuit
breaker; the corresponding earth terminal should be connected to the earth conductor
(yellow-green) of the power supply line. Table 1 (
TAB. 1
) shows the recommended
delayed fuse sizes, in amps, for the main supply, which have been chosen according
to the maximum rated current output from the heating machine, and to the nominal
power supply voltage.
WARNING! Failure to observe the above rules will render the
manufacturer’s (class I) safety system ineffective and constitute a serious risk
to people (e.g. electric shock) and property (e.g. fire).
5.3 TOOL AND FOOT CONTROL CONNECTIONS (FIG. C)
WARNING! BEFORE CARRYING OUT THE FOLLOWING
CONNECTIONS, MAKE SURE THE MACHINE IS OFF AND DISCONNECTED
FROM THE MAINS.
5.3.1 Tool connection
- Insert the tool connector into the machine outlet (
FIG
.
C-1
).
Please note: The connector can be inserted into the socket in one direction only!
- Lock the connection using the relative lever.
5.3.2 Connecting the foot control
- Connect the rubber tube as shown in
FIG
.
C-2.
- Press the tube well into the outlet to ensure that it is well connected.
6. TOOL USE
6.1 PRELIMINARY OPERATIONS
Before carrying out any operation with the heating machine, a series of checks must
be carried out with the main switch at “O”:
1- Make sure the electric connection has been carried out correctly in compliance
with the instructions given previously.
2- Make sure the heating machine is not damaged. Check the integrity of the power
cable and plug, the inductor cable, insulation, etc.
3- Connect the tool as indicated in the previous paragraph (
FIG
.
C-1
).
6.2 OPERATING PRINCIPLE
The operating principle is based on the generation of an alternate magnetic field
that the inductor concentrates on the metal piece to be heated: “eddy” currents are
generated in the piece, which is heated very quickly. The currents do not circulate
within insulation materials: therefore this system does not heat materials such as
glass, plastic, ceramic, wood, fabric, etc. The inductor generates the eddy currents
in non-magnetic materials such as aluminium, copper, silver, etc. but these materials
are not heated much because of their low electric resistance. The inductor, instead,
generates strong eddy currents in all ferromagnetic materials such as iron, steel, cast
iron, etc. which, because of their high electric resistance, are heated very quickly.
The various types of inductor make it possible to concentrate the magnetic flow,
therefore the heat, in different ways according to the use they were designed for.
Consider that the flow generated can heat metals at a distance of no more than 2 –
2.5 cm from the tool, and the closer the inductor to the piece, the more powerful the
heating power.
6.3 AUTO AND MANUAL MODE (FIG. B-3).
- AUTO (automatic adjustment): The same heating power can always be transferred
to the piece independently from the distance between the two (but remaining within
the tool working range of 2 – 2.5 centimetres). This control function is very important
especially when heating painted panels in which the temperature must not increase
too quickly to prevent burning the piece.
In the AUTO mode, the safety function that activates the inductor only when the piece
is within the tool working range is always active. In this mode, the potentiometer
(
FIG. B-4
) is disabled because the machine automatically sets the adjustment
according to the distance from the panel: the display shows the last % value used
by the machine to keep the effectively transferred heating power constant.
- MANUAL (manual adjustment): The power (as %) that the machine emits can be set
using the potentiometer (
Fig. B-4
); the display shows the selected value.
The closer the panel is to the inductor the higher the heating power, and the default
value of the AUTO mode can be exceeded notably. The LED’s in figure B-9 show
the actual heating power transmitted to the piece (“OK” refers to the default value of
the AUTO mode).
WARNINGS:
- Always use AUTO mode to avoid damaging the painted panels. In any case,
always keep the inductor at a speed of 3 – 4 cm/s above the piece to be heated
and release the pushbutton or pedal before the paint starts smoking. Never
leave the tool active on top the piece to be heated!
- It is a good idea to practice on an old car – this way the user can become more
familiar with the tools before starting to work on a client’s vehicle.
- Light-coloured paints are more delicate than dark-coloured ones because
they tend to become yellow or darken!
6.4 USING THE GLASS REMOVER
The tool (
Fig. D-a
) can remove glass from vehicles by heating the edges of the panel
where the glue that fixes the glass in position can be found. The adhesive is heated by
conduction until it detaches from the panel, which frees the glass.
FIG. E
shows the glass remover and the heat points on the panel:
the highest
concentration of heat can be found at the centre of the tool itself.
Procedure:
1- Remove the visible gaskets and the rubber or metal frames for the glass, so that
the relative plastic wedges can be applied between the glass and the panel.
2- Remove the antenna, the rain sensor, the windscreen wipers and all the
accessories that may be near the glass.
3- Clean the edges of the glass well. If necessary, use a suitable tape to protect
the visible parts of the body near the glass; this avoids scratching the paint while
working.
4- Make sure the protective tape positioned at the base of the inductor is clean and
integral; if necessary apply a new tape to avoid scratching the glass.
5- Set “AUTO” on the heating machine control panel;
6- Position the tool on the glass at a distance from the edges, as shown in FIG. F then
press the pushbutton (or foot control) and move the tool towards and in parallel
with the edge. When the machine identifies the panel it activates and begins
emitting a sound, while the LED’s illuminate in sequence up to “OK” (
FIG. B-9
)
indicating the area where the adhesive may be.
7- Make sure the adhesive is very close to the tool (better if under the tool) using a
probe as shown in FIG. F. If necessary move the tool closer to the edge of the glass
up to a distance of 1-2 cm from the body. If the user is obliged to work with the tool
too close to the visible body parts, we recommend cooling the paint with a damp
cloth or with a light film of nebulised water.
8- Begin from one corner of the glass, positioning the tool parallel to the edge at the
previously indicated distance from the body. Press the pushbutton and immediately
move the tool forward and backward over a surface of about twenty centimetres,
trying to follow the position of the glue as shown in FIG. G.
9- Slightly lift the corner of the glass, without forcing it, using the appropriate plastic
lever and at the same time push the corner with the hand from inside the vehicle.
As soon as the glass rises, insert the lever to maintain the position. If the glass has
not lifted, use the inductor to heat the area again, creating light traction with the
plastic lever.
10- Continue detaching the rest of the glass in the same way, covering small rectilinear
stretches (approx. 20 – 30 cm) at a speed of 3 – 4 cm/s.
WARNINGS:
- Remove any metal edgings from the windscreen before starting to heat,
otherwise the heat produced may damage the glass!
- The rear window is toughened glass that can splinter if worked too intensely:
use the levers but without forcing!
6.5 USING THE BOLT RELEASER
The tool (
Fig. D-b
) can concentrate the flow onto the nut, which dilates because of
heat and tends to separate from the screw, eliminating any rust or glue that may be
present. In this manner the nut that was blocked before can now be unscrewed.
The tool can be used to unscrew rusty nuts, to remove pins from doors and in general
to concentrate heat on small metal parts.
