8.1 General instructions
Caution!
Prior to commissioning, all functions must be
tested and compliance with performance data
must be checked.
8.2 Connection to Power Mains
Before commissioning, check that the rated mains
voltage and mains frequency stated on the type
plate match your power supply.
When connecting the three-phase version (SPA
2002 D) pay attention to the direction of rotation.
Warning!
Assembly, commissioning, maintenance and
repair work may only be carried out by trained and
instructed specialist personnel.
General maintenance instructions in the operating
and installation instructions for this chip extraction
system must be observed.
Warning !
When carrying out any work on the system, it
must be ensured that the power supply is switched
off (on all poles), the mains plug is disconnected
and secured against unauthorised reconnection.
Only open inspection doors when the fans are
switched off and stationary. After switching off the
device, the impeller continues to run for approx. 1
to 3 minutes.
The impeller must never by slowed down by hand
or using objects.
Prior to commissioning the system, the tight fit of all
installed filters, especially the fine dust filters, must
be checked.
The operating instructions of other connected
devices must be observed.
Always install an RCD with a maximum trip
current of 30 mA upstream.
8.3 Commissioning the chip extraction
system
The packaging film and other packaging material
must be removed. The dust extractor should be set
up as close as possible to the machine to
extracted. It should be set up on a level surface.
The lockable swivel castor must be locked at the
operation site. The filling container must be
loosened and removed from the two clamping
closures to ensure that it is ready for operation.
The chip bag (one chip bag is included in the
scope of delivery) in the filling container (1) is taken
out and unfolded. Now you put the bag into the
filling container (1)and fold it, if possible without
creases, over the edge for approx. 100 mm (fig. E).
Make sure that it lies flat particularly at the
inspection window (2) so you can read the fill level.
After retracting the container, the filling container is
inserted tightly by simultaneously operating both
clamping closures (3).
Caution!
Switch off the main switch before pulling out the
collection container.
For this activity, a dust mask (filter mask with
particle filter, filter class 2) must always be used.
Avoid covering third parties with dust.
The new dust bag is inserted as described above
(inserting the chip bag) (fig. E).
8.4 Fan
Commissioning:
1stCheck the clean air area for foreign bodies.
2.Check the impeller for free running by turning it
by hand.
3.Check the fan for dirt and unbalance, damage
and corrosion.
4.Re-tighten all fastening screws.
5.Check direction of rotation of the drive elements!
6.Check the direction of rotation of the fan (see
arrow on fan housing) by briefly switching on the
motor.
7.Correct the direction of rotation if necessary.
8.Measure the current consumption with a
completely connected chip extraction system
(pipe network) and compare it with the rated
current stated on the motor nameplate.
9.Carry out a PE conductor test.
Caution!
Danger of overloading the motor if the direction of
rotation is wrong. The current consumption must
not exceed the specified rated current. The
maximum motor speed must not be exceeded.
The maximum fan speed must not be exceeded.
Hazard warning:
Within the scope of commissioning and later
on, the fans must be checked for inadmissible
vibrations at regular intervals and the same must
be documented!
The fans must not be operated in the event of
unusual vibrations and noises or inadmissible high
vibration speeds!
Operation with inadmissible high vibration values
can cause the impellers to brake, which can lead to
serious damage to property and personal injury.
8.5 Filter (14)
8.5.1 Dedusting the filter
The filter resistance is monitored using a
manometer installed on the device (9). When the
max. permissible negative pressure (red range) is
reached, the device must be switched off and the
filter (6) must be cleaned by moving the cleaning
lever (14) up and down several times.
Caution!
Cleaning (6) is only effective when the fan is at a
standstill!
Do not move the cleaning lever up to the stop when
cleaning the filter in upward movements!
8.5.2 Cleaning the main filters
Over the course of time, the filter elements will
slowly become clogged with fine dust embedded
deep in the pores. This fine dust can no longer be
removed by the filter cleaning system. In this case,
the filter must be replaced.
8.5.3 Replacing the filter
In order to be able to replace the filter (14), at first
the cleaning device must be removed. To do this,
remove the filling container (1) in order to access
the filter chamber from below.
After removing the nuts with a wrench (AF 10), the
wiper arms (17) can be taken out individually. As
soon as the wiper arms (17) and the earthing cable
have been removed from the vibrating rod (16), the
vibration rod can (16) can be pulled out at the side
by undoing the retaining screw. Now lift the upper
cover by unscrewing the star screw (7) .
To remove the filter unit upwards, unscrew the
upper fixing screw from the silencer sleeve (8) and
cut out the putty seam on the filter retaining plate
(13) with two cuts.
When inserting the new filter unit, the steps should
be carried out in the following order (see Fig. B and
C):
- Insert the filter unit (fig. B) from the top, paying
attention to the direction of the lug for the
vibration rod (16) .
- Thread in the vibration rod (16) and secure it with
the retaining screw when it exits on the other
side.
- Insert the wiper arms (17) (make sure the recess
for the shaft is positioned correctly) and secure
with the lock nut.
- Do not forget to screw on the earthing cable.
- Now insert the screws for fastening the silencer
sleeve (8) at the top.
- Seal the filter retaining plate (13) with putty all
around.
- Place the housing cover on the filter unit and
fasten it with the star screw (7) to the bracket of
the filter unit.
- Inserting filling container
Important:
It is advisable to observe the curing time of the
putty (approx. 24 hours) before the next start-up.
8.5.4 Disposal of collected dust
When the filling container is full or when it reaches
the maximum filling level, the device must be
switched off (before, however, the dust generator
should be switched off) and the cleaning process
should be repeated. By releasing the clamping
lever (3) the filling container (1) is lowered and can
be pulled out to replace the chip bag. Now carefully
close the chip bag and remove it from the
container. The disposal must be carried out in
accordance with local provisions.
Caution!
For this activity, a dust mask (filter mask with
particle filter, filter class 2) must always be used.
Avoid covering third parties with dust.
The new dust bag is inserted as described under
point 8.3.
8.6 Connecting the extractor hose
Only use electroconductive hoses. Hoses made
from plastic must be flame-retardant.
1. At one end of the spiral hose, strip the metal
spiral so that approx. 5 cm of the metal spiral
protrudes.
2. Cut off the piece of hose that the metal spiral
was removed from.
3. Bend the stripped piece of metal spiral in such
a way that it protrudes inside the spiral hose.
4. Push the end of the hose (and one hose clamp)
over the extractor connection piece from the dust
extractor and secure with the hose clamp: Attach
the hose clamp in such a way that the stripped
metal spiral is pressed against the extractor
connection piece on the dust extractor to ensure
that there is an electroconductive connection.
Make sure that the electrical connection between
the hose and extractor connection piece on the
dust extractor is perfect.
8.7 Drive components
8.7.1 Electrical connection
Caution!
for chip extraction system 100/230!
The dust extractor is subject to special connection
conditions according to EN 61000-3-11, the
maximum permissible mains impedance at the
installation site is (0.275 + j0.172) Ω .
Caution!
for chip extraction system 100/400!
Before commissioning, please ensure that the
direction of rotation of the motor or impeller is
correct. If the direction of rotation is wrong, the
device is subjected to impermissible
temperatures. In addition, the volume flow is
reduced, thus reducing the performance of the
unit.
Important:
When commissioning, always switch on the dust
extractor first and then the dust generator. The
reverse sequence must be observed when
switching off.
Caution!
The following maintenance work is urgently
required to keep the chip extraction system in
good working order.
The regular maintenance and repair consists
of:
The fan and drive units must be checked
periodically for dirt, damage and corrosion
9.1 Daily inspection:
- Visual inspection for obvious defects or damage
to the device or parts.
- The raw gas/filter chamber must be checked for
unusual deposits and cleaned if necessary.
- Procedure for leaks: Switch off the device, seal
leaks, replace defective filters.
