Dear customer,
Electrostatic charges occurring during production processes often cause
severe disruptions, reducing production speed and product quality.
The R36 ion blower nozzle, the PR36 ion blower pistol, the LR36 ion
blower nozzle bar and the EAR36E discharge adapter are components of
the newly developed discharging system with outstanding range and
depth effect. This is particularly important in winding reels up or down
because the reel diameter and therefore also the distance from the dis-
charging units changes. The powerful decoupling effect of neutralizing
charge particles supported by the blown air results in a high degree of effi-
ciency in discharging, even at larger distances from the product.
Charged surfaces which attract dirt particles can be effectively discharged
with the help of either the blower pistol or the blower nozzle, keeping the
surfaces free of dust before converting and finishing.
Designing the ion blower nozzle as an adapter allows the integration of
the ionization system into commercial blower nozzles. The combination of
ionization with a high degree of efficiency and flow-optimized air nozzles
results in synergies showing in excellent discharge performance.
The R36 ion blower nozzle, the PR36 ion blower pistol, the LR36 ion
blower nozzle bar and the EAR36A discharge adapter are characterized
by the following features:
• high degree of discharging efficiency
• compact design
• adapter design
• small dimensions
• easy installation
• flow-optimized air nozzle
• variable air supply
The compact design of the ion blower nozzles and its high efficiency allow
a wide variety of applications. Flexible ball-joint hoses allow the accurate
alignment of individual nozzles.
Each single nozzle is equipped with an air cock to select any desired flow
profile. The air can be connected to the existing air supply or to an
optional compressor.
The ion blower nozzle is used in fixed installations; the ion blower pistol is
designed for manual use.

6BA-en-2043-2307_R36
The EAR36E discharge adapter is specially designed for neutralising elec-
trostatically charged and thus adhering pneumatically conveyed goods in
the hose system and/or a downstream metal hopper.
The injected ions discharge and loosen the adhering conveyed material
(granulate) and thus reduce the standstills required for cleaning the con-
veyor system.
Please read the operating instructions carefully before operating the unit.
This will help you prevent personal injuries and damage to property.
Please note and observe the safety and warning notices.
Please give us a call if you have any suggestions, proposals or ideas for
improvements. We greatly appreciate the feedback from the users of our
appliances.

2. Safety
The units have been designed, built and tested using state-of-the-art engi-
neering, and have left the factory in a technically and operationally safe
condition. If used improperly, the units may nevertheless be hazardous to
personnel and may cause injury or damage. Read the operating instruc-
tions carefully and observe the safety instructions.
For warranty conditions, please refer to the General Terms and Conditions
(GTC), see www.eltex.de.
2.1 Identification of risks and hazards
Possible risks and hazards resulting from the use of the units are referred
to in these operating instructions by the following symbols:
Warning!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in serious personal injuries.
Caution!
This symbol appearing in the operating instructions refers to operations
which, if carried out improperly, may result in damage to property.
2.2 Contact protection
The site of installation and/or use of the units is outside the control of
Eltex, contact protection against inadvertent contact of the bars and of live
components by personnel as specified by the employer’s liability insu-
rance association may have to be provided (e.g. DGUV V3 in Germany).
Contact protection devices made of conductive material must be
grounded.
2.3 Inspection of the protective resistors - contact protection
The function and the appearance of the protective resistors must be
inspected at regular intervals. The inspection intervals are specified in the
accident prevention regulations, as amended (e.g. in Germany DGUV
V3).
The function of the series resistors must be checked using a suitable
measuring device. The test voltage must be 1,000V. The measured resis-
tance between the high-voltage connection and the individual emission tip
must not fall below 80 MOhm and not exceed 120 MOhm.

BA-en-2043-2307_R36 15
2.4 Technical advance
The manufacturer reserves the right to make changes to the technical
specifications without prior notice in order to adapt the units to state-of-
the-art engineering. Eltex will provide the latest information on any
changes or modifications in the operating instructions on request.
2.5 Proper Use
The R36/R36E ion blower nozzle, PR36 ion blower pistol, LR36 ion blower
nozzle bar and the EAR36E discharge adapter must be used only for dis-
charging static surfaces, for separating stacked or wound sheets, for
cleaning dusty surfaces and for neutralising charged conveyed goods.
The R36f/R36E ion blower nozzle, PR36 ion blower pistol, LR36 ion
blower nozzle bar and the EAR36E discharge adapter must be operated
only together with the 5 resp. 6 kV AC Eltex power unit which ensures an
optimum match with the required operating conditions.
Other uses are not permitted. The manufacturers will not assume any
liability and warranty if the units are used improperly or used outside the
intended purpose.
Modifications or changes made to the devices are not permitted.
Use only original Eltex spare parts and equipment.
2.6 Work and operational safety
Warning!
Carefully observe the following notes and the complete chapter 2 "Safety”,
page 15!
• Before carrying out repairs, cleaning or maintenance work and before
resetting after malfunctions, switch off the power supply and disconnect
the mains supply voltage (see chapter 5 "Maintenance”, page 29, chap-
ter 6 "Troubleshooting”, page 31).
• Before carrying out any work involving the units, the machine which has
the units fitted must not be in operation (see chapter 5 "Maintenance”,
page 29, chapter 6 "Troubleshooting”, page 31).
• Any work involving the units must be carried out by qualified electrici-
ans (see chapter 5 "Maintenance”, page 29, chapter 6 "Troubleshoo-
ting”, page 31).
• The bars passively absorb energy from the moving substrate web. The
high voltage cable must be plugged in or grounded to the generator. If
the high voltage cable is disconnected, the plug is live (high voltage)
and applies with full power on the plug; this may cause a spark dis-
charge and may lead to a risk of injury. Disconnected high voltage plugs
are not permitted or have to be grounded (see chapter 5 "Mainte-
nance”, page 29).

16 BA-en-2043-2307_R36
• The minimum spacing between the ion blower nozzle tip and grounded
metal parts should be 10 mm (see chapter 3.1 "Installation”, page 20).
• Connect or disconnect the high voltage cables only with the power sup-
ply switched off (see chapter 3.2 "Connecting the high voltage cable to
the ion blower nozzle”, page 21, chapter 3.3 "Connecting the high vol-
tage cable to the power supply of series ES5x, ES6x, ES24 and PI”,
page 22).
• Depending on the type of power supply unit, only devices with a perma-
nently connected high voltage cable (e.g. R36E, PR36) are permitted
(see chapter 3.3 "Connecting the high voltage cable to the power sup-
ply of series ES5x, ES6x, ES24 and PI”, page 22).
• In applications involving moving ion blower nozzles, the high voltage
cable must be attached such that there is no cable movement near the
connection zone of the ion blower nozzles and the power supply unit.
Use suitable clamps to attach the high voltage cables (see chapter 3.3
"Connecting the high voltage cable to the power supply of series ES5x,
ES6x, ES24 and PI”, page 22).
• In units equipped with existing ground cables, the cables must be per-
manently connected to ground potential. The ground cable should have
a minimum cross section of 1.5 mm2(see chapter 3.4 "Connecting to
ground (LR36)”, page 22).
• Check the units and the high voltage cables at regular intervals and
before startup for any damage. Any damaged components must be
repaired or replaced before continuing to operate the unit, or the units
must be disabled.
Warning!
The cable is permanently fixed to the PR36 ion blower pistol, the R36E
ion blower nozzle and the EAR36E discharge adapter and must on no
account be changed; the cables of the LR36 ion blower nozzle bar must
also not be changed.
In the event of defects, please notify Eltex Service or return the unit for
repair.
• The high voltage cable must be routed to make sure that it does not
make contact with moving machine parts. Avoid mechanical deforma-
tions and bending radii smaller than 60 mm. The high voltabe cable must
not be installed on the floor, as it may break under load; the cable must
also not be subjected to tensile stress (see chapter 3.5 "Routing the high
voltage cable”, page 22).
• The air hose must be routed to make sure that it does not make contact
with moving machine parts. Avoid mechanical deformation and exces-
sively small bending radii (see manufacturer´s specifications); see
chapter 3.7 "Routing the air hose”, page 23.
• Cleaned apparatuses air must be used as compressed air (see chapter
3.8 "Compressed air properties”, page 23).

BA-en-2043-2307_R36 17
• To ensure that the permissible operating temperature is not exceeded,
the blower nozzle, the ion blower pistol or the ion blower nozzle bar
must not be exposed to direct heat radiation (see chapter 3.9 "Impact of
heat radiation”, page 23).
• Do not open the balancer! It holds a set of springs which may result in
personal injury if used improperly (see chapter 3.10 "Balancer
(optional)”, page 24).
• To avoid severe damage, keep other objects from hitting against the
nozzle (see chapter 4 "Operation”, page 28).
• Make sure that the units are clean at all times.
Dirt results in malfunctions and in premature wear of the units.
• When cleaning the units do not soak the units and the high voltage
cable in solvent and do not damage the emission tips; allow the solvent
to evaporate completely before restarting the unit (see chapter 5 "Main-
tenance”, page 29, chapter 6 "Troubleshooting”, page 31).
• Do not touch the emission tips - risk of injury.
If the high voltage supply is connected, reflex responses to electrical
irritation can lead to secondary accidents. The charging bar as such is
safe to touch. If contact is made (single touch), the energy transferred
is so low that there is no risk of injury.
• Potential risk for wearers of cardiac pacemakers:
Moving the chest closer than 3.5 cm to the emission tips of the dis-
charging bar or making surface contact with several emission tips
(touching a single tip is not critical) can result in a temporary switchover
of the cardiac pacemaker into the fault mode. Permanent proximity or
contact can therefore cause severe problems. If it is likely that the chest
of such a person comes closer than 3.5 cm to the emission tips of the
discharging bar, or if several emission tips are touched at the same
time, the appropriate warning notices must be displayed.
• The operation of the units can generate ozone. The ozone concentra-
tion levels developing near the bars depend on many different factors
such as site of installation, bar current and voltage, air circulation, etc.,
and can therefore not be specified in general terms.
If the maximum allowable concentration of ozone must be observed at
the site of installation of the bar, the concentration must be
measured on site.
The AGW value (maximum admissible concentration) serves to assess
the ozone concentration at the workplace. The user must make sure
that the appropriate national AGW value is at no times exceeded, e.g.
in Germany the ozone concentration occurring during the operation of
the system must not exceed the recommended value based on interna-
tional limits of 0.06 ml/m³ (0.12 mg/m³).

3. Installation and assembly
3.1 Installation
The ion blower nozzles can be mounted via the attachment lugs of the bar
element using M5 screws.
The fishtail nozzle may be attached using the attachment lugs of the
blower nozzle.
The fishtail nozzle can be turned by 0...360° (max. 1 turn). To turn, loosen
the lock nut (4, Fig. 1) and tighten again after adjustment.
The compact fishtail nozzle can be set in request position using a clamp.
The version with the extensions (especially with the rotary nozzle) must
also be secured in place mecanically in the area of the extension.
To prevent damaging the nozzles, we recommend the use of a balancer
together with an ion blower pistol. A balancer is available as optional
equipment under article no. 111569.
Use the attachment angle pieces to mount the ion blower nozzle bar to the
wall of the machine or directly with the groove to the back of the profile.
During mounting, grounding as specified by the Machinery Directive must
be observed.
The blower nozzles can be positioned via a flexible ball joint hose.
The EAR36E discharge adapter is pressed into the upward-pointing
branch of a Y-branch pipe to be provided by the customer. To prevent
damage to the O-ring during installation, we recommend that the customer
fit an insertion chamfer, see Fig. 5.
Furthermore, it must be ensured that the Y-pipe is installed in such a way
that the discharge adapter and thus the ions are blown in in the material
conveying direction, see Fig. 5.
Warning!
For safe operation, please note the following:
• The minimum spacing between the ion blower nozzle tip and grounded
metal parts should be 10 mm.

3.2 Connecting the high voltage cable to the ion blower nozzle
Depending on the unit version, e.g. PR36, R36E or EAR36E with a fixed
high voltage cable, the high voltage cable is fixed connected to the ion
blower nozzle.
Unit version with detachable cable connection:
Warning!
Connect or disconnect the high voltage cable only with the power supply
switched off.
Connect the ion blower nozzle to the power supply using the prefabricated
high voltage cable. Push the high voltage cables into the sockets up to the
stop. Then the cable gland is screwed in up to the stop.

Depending on the type of power supply unit, only devices with a perma-
nently connected high voltage cable (e.g. R36E, PR36) are permitted.
Connect the ion blower nozzles to the power supply using the prefabri-
cated high voltage cable. Push the high voltage cables into the sockets up
to the stop. Then secure the adapter in the socket with the clip provided
(see Fig. 6).
Warning!
In applications involving moving ion blower nozzles, the high voltage cable
must be attached such that there is no cable movement near the connec-
tion zone of the ion blower nozzles and the power supply unit. Use suita-
ble clamps to attach the high voltage cables.
3.4 Connecting to ground (LR36)
In units equipped with existing ground cables, the cables must be perma-
nently connected to ground potential. The ground cable should have a
minimum cross section of 1.5 mm2.
3.5 Routing the high voltage cable
The high voltage cable must be routed to make sure that it does not make
contact with moving machine parts. Avoid mechanical deformations and
bending radii smaller than 60 mm. The high voltabe cable must not be
installed on the floor, as it may break under load; the cable must also not be
subjected to tensile stress.
