WARNING! Risk of personal injury
• Ensure that there is no vacuum present in the
system during service.
• Always disconnect the compressed air supply
before any service.
Check all power conductors and protective con-
ductors one month after installation and tight-
en, if required, to ensure good contact. Service
to the electrical equipment may only be carried
out by a qualified electrician.
One month after installation, and then every year,
perform the following checks:
• Check all power and protective conductors and
ground wire connections. Tighten, if required, to en-
sure good contact.
• Inspect the integrity of the dust separator.
• Ensure that the inside of the unit and the connec-
tion ducts are free from deposits. A build-up of de-
posits inside the duct system may cause the dis-
charge of static electricity.
• Clean the area around the unit and all areas where
the collected material is stored to ensure that there
are no dust deposits.
• Check that all signs/markings regarding safe opera-
tion are in place and that the personnel knows about
them.
• Verify the function of all emergency stop buttons,
alarms and signalling devices.
6.2 Empty the collector bin
WARNING! Risk of personal injury
• Ensure that there is no vacuum in the dust
separator before removing the collector bin.
• Crush hazard. Be careful when lowering and
refitting the collector bin. Use proper pro-
tective equipment.
• Wear goggles, a dust mask and gloves when
emptying the collector bin.
The plastic bag is to be replaced when filled up
to 2/3, see Figure 11 .
Do the following to replace the plastic bag:
1 Ensure that there is no vacuum in the dust separ-
ator.
2 Remove the collector bin.
3 Seal and remove the plastic bag. Use a cable tie or
equivalent, see Figure 12 .
4 Fit a new plastic bag in the collector bin, see Fig-
ure 13 .
5 Refit the collector bin onto the dust separator.
6 Check that the pressure equalizer hose is attached
to the collector bin, see Figure 14 .
7 Check that the collector bin seals properly once
the vacuum is re-applied to the dust separator.
6.3 Replace the main filter
Fitting the steel ring correctly is important to
maintain the tightness and durability of the
unit, see Figure 7 .
Filter replacement is to be noted in the service pro-
tocol of the unit. Replacing individual filter bags is
possible, but it is recommended that the whole filter
package is replaced since it is quicker and causes less
spreading of dust. The work is easy if the unit is placed
so it can be tilted, see Figure 15 . Also, the filter may be
lifted straight up, see Figure 16 , with a crane or other
lifting device.
If the filter bags are replaced separately, the plastic
holders will also have to be replaced.
Figure 17 , items A–C, shows how the rubber sealing
rings are to be fitted. When a used sealing ring is to
be re-used, the form when open may differ from the
original form as shown in item A. Use a screwdriver to
bring the edge of the module between the rubber lips
to obtain the result shown in item C.
6.4 Check the filter cleaning function
WARNING! Risk of personal injury
Crush hazard. Pay attention when the com-
pressed air pressure cylinder and valve disc
move. Make sure that the protection hood over
the filter cleaning unit is fitted after the check.
Check the automatic filter cleaning as follows:
1 Check the automatic cleaning equipment once a
year.
2 Remove the top cover from the filter and inspect
the valve disc.
3 Start the unit and press the filter cleaning button,
see Figure 8 . The compressed air cylinder should
lift the valve disc. Loud noise can be heard as air
rushes into the filter bin to blow off the dust from
the outside of the filter package. This will be re-
peated 3 times for each filter cleaning cycle.
4 Stop the vacuum unit and shut off the air supply.
5 Check the valve disc fastening, damage and wear.
Replace if required.
6 Replace the protecting top cover.
6.5 The motor and the fan unit
Inspect and clean the motor compartment regularly.
The motor has 2 ball bearings. The bearings are to be
replaced after approximately 15,000 hours of opera-
tion. If the ambient temperature often reaches 35°C
(95°F), the time between replacements is to be re-
duced. In any case, the bearings are to be replaced
every fifth year.
