ating instructions, cleaning pad
See figure
and the explanation of operating compo-
nents and tool parts on page 1.
The following conditions must always be observed
when the unit is in use:
– The unit must be connected to an alternating current
electric mains supply in compliance with the infor-
mation given on the type plate.
– The unit may be used only with the supply cord for
the DD EC-1 diamond drilling machine (with built-in
GFCI ground fault interruptor).
– The unit must not be operated in areas where there
is a risk of explosion.
Main features of the unit

– Water is retrieved from the drilling slurry (recycling)
– Supplies water and power for the DD EC-1 diamond
core drilling machine
– Integrated supply and return hose set for connect-
ing the DD EC-1 diamond core drilling machine
– Automatic filter flushing
– Filter can be regenerated
– Stand-by operation
– Warning indicators for:
- inadequate water flow
- overheating

Intended uses
The unit is intended for the following uses
– Extraction of drilling slurry and supplying water and
power to the DD EC-1 diamond core drilling machine
for drilling in mineral materials (reinforced concrete,
masonry and natural stone)
– The unit may be operated only when positioned on a
horizontal surface and in an upright position.
– Caution: Clean water should be used as the cooling
and flushing medium.
The water recycled by the unit is almost entirely
free of particles but may contain substances released
Do not, under any circumstances, use this prod-
uct in any way other than as described in these
operating instructions.
by the material in which the hole is drilled. Under no cir-
cumstances should this water be considered suitable
for use as drinking water.
Only to be used with DD EC-1.
