Verehrter Kunde
The Static Combi Cleaner SCC is a high-power ionization cleaning station
for the non-contacting removal of dust and dirt deposits on three-dimen-
sional or structured surfaces.
Static dust is discharged and blown off by a rotating nozzle with two air out-
lets. The rotation creates a pulsating effect on the surface. The nozzle dia-
meter and the angle of the air jets can be adjusted independently of each
other.
The effective elimination of static charges from cleaned surfaces prevents
dust from settling back on product surfaces. The cleaning unit with concen-
tric suction flow is designed for integration into flowing manufacturing pro-
cesses; a relative movement between the component and the SCC-P is
required for the desired cleaning effect.

2.6 Work and operational safety
Warning!
Carefully observe the following notes and the complete chapter 2 "Safety”,
page 8!
• 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 17, chap-
ter 5 "Maintenance”, page 17).
• 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 17, chapter 5 "Maintenance”, page 17).
• Any work involving the units must be carried out by qualified electrici-
ans (see chapter 5 "Maintenance”, page 17, chapter 6 "Troubleshoo-
ting”, page 19).
• Connect/disconnect the high voltage cables only if the power supply
unit is switched off (see chapter 3.4 "Connecting the high voltage cable
to the ion blower nozzle”, page 14, chapter 3.5 "Connecting the high
voltage cable to the power supplies of series ES5x, ES6x and PI”,
page 14).
• For units with existing ground cables, these must be permanently con-
nected to ground potential. The ground cable should have a minimum
cross section of 1.5 mm2 (see chapter 3.6 "Connecting to ground”,
page 14).
• 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 R36 ion blower nozzle and must
on no account 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 3.7 "Routing the high
voltage cable”, page 15).
• 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 3.9 "Routing the air hose”, page 15.
• Cleaned apparatuses air must be used as compressed air (see chapter
3.10 "Compressed air properties”, page 15).

BA-en-2087-2207_Static Combi Cleaner SCC_P 11
• To ensure that the permissible operating temperature is not exceeded,
the blower nozzle must not be exposed to direct heat radiation (see
chapter 3.11 "Impact of heat radiation”, page 15).
• To avoid severe damage, keep other objects from hitting against the
nozzle (see chapter 4 "Operation”, page 16).
• 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 in solvent and do not
damage the emission tips; allow the solvent to evaporate completely
before restarting the unit (see chapter 5 "Maintenance”, page 17, chap-
ter 6 "Troubleshooting”, page 19).
• 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).

3.2 Connecting the suction line
The unit is designed for a static conductive suction hose with a nominal dia-
meter of 50 mm in a light version. (e.g. Airduc PUR 351 EC D=50 mm).
Metal hose clamps must be grounded.
3.3 Adjusting the suction apron
The distance (A) of the rotation nozzle to the product in interaction with the
air pressure must be adjusted individually. To prevent the ablation from rea-
ching the surroundings, the apron should be guided as close as possible to
the object or the support system. If the gap (D) is less than or equal to
3 mm, complete suction is possible.

It is intended that the apron (3) be shortened to dimension (C) by the cus-
tomer and a contour be cut if necessary. The 1 mm thick conductive poly-
carbonate film should be worked on with a suitable cutting tool. From an
apron length (C) of less than 60 mm, the lower wire clamp is no longer
necessary..
3.4 Connecting the high voltage cable to the ion blower nozzle
The high voltage cable is fixed permanently to the ion blower nozzle.
3.5 Connecting the high voltage cable to the power supplies of
series ES5x, ES6x and PI
Warning!
Connect or disconnect the high voltage cables only with the power supply
switched off!
Connect the ion blower nozzles to the power supply using the prefabrica-
ted high voltage cable. Push the high voltage cables into the sockets up to
the stop. Then secure the cable in the socket with the clip provided (see
Fig. 5).
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 sui-
table clamps to attach the high voltage cables.
3.6 Connecting to ground
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.

BA-en-2087-2207_Static Combi Cleaner SCC_P 15
3.7 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.
3.8 Connecting the compressed air
The R36 ion blower nozzle is supplied with a plug-in connection for pneu-
matic hoses with an outer diameter of 8 mm. The plug-in connection can
be replaced by other hose connections with a G 1/4" or R 1/4" screw
thread.
3.9 Routing the air hose
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).
3.10 Compressed air properties
The compressed air must be free from oil, water and dust. If the air supply
hoses are very long, a water separator must be fitted immediately
upstream from the ion blower nozzle, the ion blower pistol or the ion
blower nozzle bar. Maximum rated air pressure depends on the used
nozzle type (see chap. 7 Technical specifications).
3.11 Impact of heat radiation
To ensure that the permissible operating temperature is not exceeded, the
blower nozzle must not be exposed to direct heat radiation.
Please also observe the operating instructions for the ion blower nozzles
R36, BA-en-2043 for all connections.

BA-en-2087-2207_Static Combi Cleaner SCC_P 17
5. Maintenance
Warning!
Electric shock hazard!
• Switch off the power supply unit and disconnect the supply voltage
before carrying out any maintenance or repair work.
• 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 discharge and
may lead to a risk of injury. Disconnected high voltage plugs are not per-
mitted or have to be grounded.
• The machine which has the units fitted must not be in operation.
• Repairs and maintenance work must be carried out by qualified electrici-
ans only.
• Disconnect the compressed air supply before carrying out any mainte-
nance or repair work.
5.1 Cleaning
To ensure the trouble-free function of the ion blower nozzles, the surface
from which the emission tip and the blown air exit must be clean and dry at
all times. Dirty blower nozzles must be cleaned with a suitable solvent (ben-
zine) and a brush with soft plastic bristles (Eltex article RBR22). To prevent
the air exit holes from clogging up with dirt during cleaning, the compressed
air (0.3...0.5 x 105 Pa) must be switched on during cleaning.
Warning!
Risk of deflagration!
Allow the solvent to evaporate completely before restarting the unit.
Caution!
Do not damage the emission tips when cleaning.

18 BA-en-2087-2207_Static Combi Cleaner SCC-P
5.2 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.
Please additionally observe the operating instructions for the ion blower
nozzles R36, BA-en-2043.
