9.3.5.4 Replacing the Filter Cartridge, Cleaning the Filter Bowl
NOTE
This work should only be carried out when there are no components in the star as the machine needs to be
switched off for this work.

Switch the automatic placement system off at the main switch and disconnect from the power supply.
●
Remove the cover over the compressed air unit from the machine base
(see Fig. 9.1.1, Page 9 - 3). To do so, unscrew and remove the two special hexagon socket screws using
a size 3 hexagon socket spanner.
●
In addition turn off the compressed air supply at the stop valve of the compressed air unit (see Fig. 9.3.5,
Page 9 - 29).
●
Open the drain plug for draining the condensate to reduce the pressure in the compressed air hoses (see
Fig. 9.3.5, Page 9 - 29).
●
Remove the filter bowl by rotating it a quarter-turn and pulling it downwards (bayonet closure).
●
Clean the filter bowl if necessary. Only use soapy water for this.
●
Empty the condensate container.
●
Unscrew and remove the support spring and remove the sealing ring.
●
Pull the filter cartridge downwards and out.
●
Slide in the new filter cartridge.
●
Place the seal on the threaded rod and then screw on the support spring. The black plastic disk must be
placed in the filter bowl.
●
Screw the filter bowl back on.
●
Open the stop valve of the compressed air supply (see Fig. 9.3.5, Page 9 - 29).
●
Switch the machine back on at the main switch.
●
Check the pressure at both manometers:
–
operating pressure of the lefthand manometer: 5.6 bar
–
operating pressure for the stopper at the right-hand manometer: stopper: 2.3 bar
NOTE
If, despite changing the filter cartridges, the manometers still do not show 5.0 bar and 2.3 bar this will be
due to other reasons, as described in Section 9.3.5.1 from Page 9 - 28.
●
Fit the cover plate back on the machine base using the size 3 hexagon socket spanner.

9.3.6 Emptying the Rejects Container for the IC Head (SIPLACE 80F)
As regards the position of this rejects container at the machine base, please refer to Fig. 9.3.6.
●
The machine is switched off at the main switch and the sliding safety hoods are open.
●
Check first whether the z axis (sleeve) is in its top end position. If it is not, this indicates a fault. You should
inform Siemens’ SMD service department.
●
Move the gantry away from the rejects container by hand. Do not touch the placement head.
●
Lift the rejects container vertically upwards and off the magnetic disk, making sure that no components
drop into the working area of the machine.
●
Place the empty container back in the center of the magnetic plate.

9.3.7 Cleaning the IC Head Nozzle Changer (SIPLACE 80F)
NOTE
Carry out maintenance of the nozzle changer whenever possible in conjunction with maintenance or inspec-
tion of the nozzles since for this work the nozzles have to be removed from the nozzle changer and afterwards
put back in their correct allocations.
The position of the nozzle changer in the machine base is shown in Fig. 9.3.6.
