Machine service
T
he DC 11-module should be tested and
maintained once a year. Worn parts must be
changed.
Do not jeopardise function and lifetime. Use only
Dustcontrol spare parts.
During maintenance and service the machine
must be switched off at the main switch.
Lubrication (1) (for the DC 11-Module S and
P models)
The turbopumps bearing should be lubricated
at least once a year with lithium saponi
fi cated
roller bearing grease, Part No 9683.
• Release
rear bearing cooling fl ange.
• Check the grease condition and
fi ll until 2/3
of the cover volume.
• Change the
O-ring, Part No 4789, and re-
mount the cooling fl ange.
Filter change (3)
It is important that the fi lter is changed when it can
no longer clean ef fi ciently. The space between
the changes depends on which type of dust you
extract and the air
fl ow the fi lter is exposed to.
The fi ne fi lter should be changed at least once per
year. Only a Dustcontrol fi lter should be used. Use
breathing protection during the fi lter change. Do
not expose unprotected persons to harmful dust.
1. Turn off and lock the power disconnect switch.
2. Use breathing protection
3. Disconnect the top of the cyclone
4. Disconnect the locking ring for the
fi lter.
5. Lift out the fi ne fi lter and seal it in a plastic
bag.
6. Lift in the new fi lter cartridge
7. Re-connect the fi lter locking ring
8. Lift the top on and connect.
Service DC Green System
DC Green System (2b):
The function of the sensors should also be check-
ed in conjunction with servicing of the pump.
1. Check the switchover between energy-saving
mode and control mode according to ”Test run-
ning” above.
2. Check the operating pressure when the sys-
tem is in control mode (at least one outlet open).
Service DC 11-Module
If the thermal sensor alarm occurs, the function of
the
fl ow sensor should be investigated fi rst. If the
system does not switch to energy-saving mode
when all the outlets are closed the pump will over-
heat. This fault can be due to the failure of the
fl ow
sensor to function as it should, to the presence of
e a major leak in the system, or to the extraction
equipment that is being used admitting too little air.
