point does not improve the efficiency of the filter seal
and may result in permanent damage to the filter or
cover parts.
– Fill the container as described above, close it and then
insert it in the housing.
Drying the main filter
– In rare cases, regeneration of the main filter may not
be sufficient to clear a blockage. Should this be expe-
rienced, allow the main filter to dry for at least 24
hours in a warm, dry place before it is reused.
Replacement main filter
– The main filter is a wearing part with a limited life
expectancy. The housing has provision for storing a
spare main filter (not supplied). A spare filter is
recomended. The container must be removed on order
to access the storage location and insert a spare filter.
Insert the grip section of the spare main filter in the
holder in the base of the housing at an angle and then
bring the filter into a vertical position until it engages
with the plastic tab. To remove the spare main filter,
lift the plastic tab slightly and pull the filter out of the
holder to the side.
Switching off after use
– Before each long break between periods of use (e.g.
after finishing work for the day), the recycling unit
must be switched off as follows:
1. Disconnect the main plug.
2. Release the hose connectors to the diamond core
drilling machine. Connect the extraction hose and
water supply hose couplings together.
3. Release the keyed plug from the diamond core
drilling machine. To do this, pull on the ring and
turn the plug in a counterclockwise direction, as
far as it will go, and then pull it out.
– Proceed as follows in order to avoid malfunctions
caused by dirt deposits:
1. Clean the container tank and main filter.
2. Refill with fresh water.
3. Plug the supply cord into the mains socket.
4. Switch on the PRCD/GFCI by pressing the green but-
ton.
5. Switch on the unit by turning the ON/OFF switch in a
clockwise direction, as far as it will go.
6. Run the recycling unit for 10 minutes. Switch the recy-
cling unit on/off at the main switch four times during
these 10 minutes. This will flush out the internal tub-
ing and valves of the recycling unit.
7. Disconnect the mains plug.
– Clean the container and regenerate the main filter.
– Allow the main filter to dry in a warm, dry place.
Storing the main filter in water for a long period may
cause it to become blocked and thus reduce its life
expectancy.
– Do not close the container and cover. Leave them
open until they are completely dry.

Transport without wheel assembly
– A handle, which can be folded out easily, is provided
for transporting the unit by hand. Grip sections are
provided at the sides for lifting the unit with both
hands. Take care to avoid pinching your fingers at the
grips.
– A suitable means (net or straps) must be used
when the unit is lifted by a crane. The wheel
assembly, housing or container grip must never be
used as a lifting point for a crane hook or other sim-
ilar lifting tackle. When transporting the unit by crane,
the applicable safety regulations must be observed
.
Transport with wheel assembly
– Attaching the wheel assembly: Hold the unit against
the guide tubes on the wheel assembly and allow it
to slide down until the catch engages automatically.
Take care to ensure that the feet of the unit are locat-
ed in the corresponding sockets in the wheel assem-
bly .
– Wind the hose set around the wheel assembly han-
dle for transport. If desired, the toolbox for the DD
EC-1 diamond core drilling machine can be placed on
the unit first.
– Detaching the wheel assembly: Push the lever to dis-
engage the catch and, at the same time, lift the unit
away from the wheel assembly.
– When using the wheel assembly, care must be
taken to ensure that the wheels and the unit are
standing securely. For safety reasons, the wheel assem-
bly must not be used when working from scaffolding
or similar platforms.

Care and maintenance

Care
The housing, container and cover are made of impact-
resistant plastic. The protective sleeve of the cable and
the hoses are made of an elastomer material. The out-
er sheath of the hose set consists of a hard-wearing
woven synthetic material.
Clean the parts of the unit regularly with a
damp cloth. Do not use spray equipment, a
steam cleaning system or running water for cleaning.
This may negatively affect the electrical safety of the unit.
Always keep the grip sections of the unit free of oil and
grease. Do not use cleaning agents which contain sili-
cone. Do not allow foreign objects to enter the interior
of the unit.
Regenerate the main filter and clean the container at
regular intervals, particularly before each long pause
between periods of use (e.g. at the end of the work-
ing day). Check the entire diamond drilling system for
leakage before each period of operation. Check and
