Before use

It is essential that the safety rules printed in
these operating instructions are read
and observed. Also read and observe the instructions
and safety precautions listed in the operating instruc-
tions for the DD EC-1 diamond core drilling machine.
The DD-REC1 water recycling system should
be used exclusively with the DD EC-1 dia-
mond core drilling machine and the corresponding sup-
ply cord with built-in GFCI ground fault interruptor (sup-
plied with the DD EC-1 diamond core drilling machine).
The mains voltage must comply with the infor-
mation on the type plate.
If extension cables are used: only extension cables
of a type approved for the intended use and of ade-
quate cross section may be used. Failure to observe this
point may result in reduced performance and could cause
the cable to overheat. Damaged extension cables must
be replaced.
The recommended AWG and maximum lengths are as
follows:

Assembly

Connecting the hose set to the drilling machine
– Connect the keyed electric supply cord plug from the
hose set to the socket on the underside of the drilling
machine. To do this, bring the marks on the plug and
the socket into alignment and then push the plug into
the socket on the machine as far as it will go. While
maintaining slight pressure on the plug, rotate it in a
clockwise direction until it is heard to engage
– Connect the thin end of the hose from the hose set to
the drilling machine and the thick end of the hose to
the water collector hose connector. The couplings
must be heard to engage when connected.
Removing and opening the container
– Never remove the container while the unit is
switched on. Switch the unit off by turning the
on / off switch in a clockwise direction and discon-
nect the mains plug
– Wear protective gloves and protec-
tive goggles. The contents of the container may irri-
tate the skin and eyes. The container and its contents
may be hot after long periods of use. Observe the

safety rules When handling the container, take care
to avoid pinching your fingers at the edges of the
housing, chips and latches.
– Lift the container grip approx. 45° and hold it in this
position until pressure compensation is heard to be
complete (approx. 2 seconds). Failure to observe this
point may cause a large quantity of the container con-
tents to escape at the nipples.
– Lift the container grip to the vertical position and pull
the container upwards out of the housing
– Always transport the container in an upright position
or place it on a horizontal surface.
– Ensure that it stands securely.
– Open the four container cover latches
– Lift the cover off the container and ensure that the
glaat doesn't get stuck. Place the cover gently on its
feet.
Filling, closing and inserting the container
– Fill the inner container up to the top edge with clean
water . Fill the outer container to the desired level
between the min. and max. marks.
– Check the inner and outer cover seals for damage.
Carefully remove dirt from the surfaces of the seals.
Ensure that the main filter is seated securely. Check
that the air release valve moves easily ¸.
– Place the cover on the container. Take care to ensure
that it is positioned correctly: The nipples of the cov-
er are on the same side as the volume sight glass.
When the cover is placed in position, take care to
ensure that the container latches and the float hose
are not pinched between the container and the cover
.
– Close the container latches. To do this, first engage
the latches on the container and then press the latch-
es towards the cover. The container latches must be
heard to engage. It may be necessary to press the
cover down slightly.
– Always use all four container latches. Never use
the unit when the container latches are dam-
aged.
– Lift the container by its handle and insert it carefully,
the right way round, in the housing. When doing so,
the guide ribs on the container must be carefully insert-
.
ed into the corresponding openings in the housing. Do
not allow the container to drop into the housing
– Fold the container handle down to the nipples side
until it is flush with the top surface of the housing. It
may be necessary to press the cover down slightly.
– Never attempt to fill the unit through the hoses. It
must always be filled as described above.

Operation

– Check the sight glass to ensure that sufficient water
is in the container.
